/ 10 “CONSTRUCTIVE ARRANGEMENT IN MULTIDIAMETRAL INTEGRATED SOCKET COLLAR” Field of constructive arrangement
[001] The present constructive arrangement, belonging to the field of Mechanical Engineering, more specifically as an accessory for screwing pipe walls, making connections through the pipe walls while transporting fluid. More particularly, the present arrangement is indicated for use in treated water distribution systems, basic sanitation networks and urban hydraulic installations. It is especially recommended for branches of various materials such as cast iron, steel, polymers, among others, and allows greater flexibility and efficiency in the connection between different segments of the network, adapting to varied pressure and flow conditions found in urban supply systems.
[002] Therefore, this patent application presents an accessory specifically designed and developed for great practicality, offering significant advantages in both its use and manufacture. Furthermore, its applicability extends to urban drainage networks, where the efficiency and adaptability of the components are fundamental to optimizing hydraulic performance and ensuring low installation and operating costs, as discussed in recent studies on water distribution and drainage networks. The present application also aims to present an accessory with low industrial feasibility costs, while also meeting the requirements of robustness, safety, and practical utility, thus offering consumers an additional option in the market of similar products that, unlike conventional plug collar models, offers numerous possibilities and benefits to its users. Fundamentals of constructive arrangement
[003] As is common knowledge, fastening devices called plug collars are components that are positioned at predetermined points on Petition 870260039243, dated 04 / 28 / 2026, page 4 / 14 / 10 piping to simultaneously compose a reinforcement and a connecting element between the public pipe and residences, for example. They are basically composed of two pipe sections joined longitudinally by means of a fitting and locking system, and with a coincident lateral outlet where the connection to the residence is made. And for this purpose, this outlet has an internal thread.
[004] Several constructive arrangements applied to tapping collars are known. For example, document BR 11 2012 031285 5 A2 of 06 / 07 / 2011 teaches a tapping collar for a fluid pipeline, comprising: - a saddle intended to be applied, in a watertight manner, over this pipeline, via a gasket, having an opening intended to be placed in front of an orifice of this pipeline; means for tightening the saddle over this pipeline, comprising at least one flexible flange, intended to cooperate with the saddle to enclose the pipeline. According to the invention, this saddle and this flexible flange are adjusted in such a way as to enclose this collar over this pipeline, without discontinuity of contact of the collar between this saddle and the flexible flange, or at least limiting the discontinuity of contact between the saddle and the flexible flange.Document MU 6500930-4 U2 of 06 / 28 / 1985, for example, describes a tapping collar composed of two semicircular "U" sections, joined by a fitting and locking system, positioned at certain points in the water piping of a building for reinforcement and interconnection of internal valves, wherein the inner face of the U section(s) has part or all of its surface rough, uneven or grooved.
[005] Document MU 6802859-8 Y1 of 19 / 07 / 1988, in turn, teaches a system for anchoring a tapping collar in pipelines consisting of a clamp that surrounds the pipe, equipped with locking means and a cylindrical tubular protection, internally threaded, for threading a valve, and according to which the stresses are absorbed by the water intake hole itself, made in the pipe when the collar is mounted on it, with said collar being subjected only to a minimum tension, necessary for the structuring of the section where the hole is made; said anchoring of the collar in the pipe hole itself is effected by means of a locking element provided inside the tubular projection of the collar, equipped with appropriate retractable means, and which, when subjected to slight pressure, is displaced towards the pipe hole. Petition 870260039243, dated 04 / 28 / 2026, page 5 / 14 / 10
[006] Document MU 8302356-9 U of 09 / 18 / 2003 claims a tapping collar in the form of a single piece, formed by a body portion similar to a clamp with a longitudinal arc section and cooperating with a pipe surface, said clamp having a hole and whose body is adhered to the pipe by means of a seal.
[007] Document MU 8402873-4 U of 11 / 18 / 2004 teaches provisions introduced in a tapping collar that seeks to give it sufficient elasticity capable of relieving the stresses to which it is subjected, either in the collar or in the joining devices of the parts, when mounted on a pipe, in an attempt to eliminate the risk of breakage. It is foreseen to comprise a tapping collar composed of two main parts, which are the upper semi-collar with a pocket, the lower semi-collar and two locks, whose two semi-collars, upper and lower, will embrace a pipe, the pocket being the point to connect a connecting pipe for a building branch and through which the hole is also made in the pipe, characterized by the fact that in at least one semi-collar a profile is provided that provides in the two main parts of the same a small undulation (15) along its length, so that such small undulation generates a clearance when the semi-collar is mounted on the pipe.Document PI 8108136 of 12 / 15 / 1981 uses a similar principle, but adopts truncated conical wedges for locking between the half-parts.
[008] In the case of document PI 0203652-5 B1 of 09 / 09 / 2002, a tapping collar assembly is taught, consisting of the tapping collar itself, and a branch connection for the building branch with an attached cutting tool (bolt), said improvements being made up of the provision of a small ring-shaped protrusion in each hole of the upper tabs of the tapping collar, the provision of drawers in the lower tabs of the same, and the provision of a new form of coupling between the branch connection and the neck of the tapping collar, this coupling allowing total flexibility of rotation of the branch connection in relation to the collar itself, without compromising the sealing of the assembly.Document PI0004234-0 of 14 / 01 / 2000 teaches a device for connecting a diversion pipe to a fluid transport pipe, consisting of a support part on a pipe wall; a connection tip for the pipe; a piercing element equipped with a blade for piercing the wall of a cylindrical part that overlaps the blade, whose outer face is smooth; a cylindrical body, along an axis, which... Petition 870260039243, dated 04 / 28 / 2026, page 6 / 14 / 10 receives the drilling element and in which the drill can move by screwing, to go from a drilling position in the wall to a retracted position in the body; sealing means between the body and the drilling element; the support part, the tip, the body and the sealing means are joined by molding or overmolding, and the sealing means rest on this smooth outer face of the drilling element.
[009] Despite the widespread use of these types of tapping collars, some drawbacks can be attributed to them in current processes for fixing collars to PVC pipes. In the event of a collar displacement, caused by handling the pipe, for example, the tapping collar tends to move, and when this occurs the hole in the collar becomes misaligned with the hole in the pipe, which cannot be kept in its initial position because there is no element to center the holes. Another problem is the high pressure required to fix the tapping collar to the pipe, which can deform and consequently damage it. In addition, this type of connection requires sealing and two fasteners for the upper and lower parts, which means at least two more parts to complete the tapping collar, resulting in a lengthy assembly process and high cost due to the excessive number of parts.
[0010] There are also problems with misalignment of the sealing elements, which can compromise the tightness of the connection, favoring leaks and reducing the efficiency of the system. Additionally, the absence of adequate structural reinforcements in these systems can result in higher levels of deformation and stress under assembly and operating loads, as observed in structural analysis studies of tubular components, indicating the importance of incorporating reinforcement elements to ensure mechanical integrity and minimize failures resulting from excessive stress. Another drawback regarding the use of collars of these types of existing taps is the susceptibility to fatigue and progressive failures in the sealing elements under repetitive loading conditions, such as hydraulic impacts or pressure variations, since such effects have been proven critical to the durability and efficiency of connection systems in high-pressure applications. Petition 870260039243, dated 04 / 28 / 2026, page 7 / 14 / 10
[0011] Please note that it is impractical to think that even engineered designs can completely eliminate such vulnerabilities, and it is necessary to adopt additional mitigating measures, such as continuous monitoring of operating conditions and the development of materials that are more resistant to fatigue. Description of the construction layout
[0012] The present constructive arrangement concerns a multi-diameter integrated tapping collar system, intended for fixing and sealing piping systems in water and sanitation distribution networks, presenting a constructive configuration that allows its adaptation to different nominal pipe diameters.
[0013] In general, the device comprises a body preferably made of AISI 304 stainless steel, which has a structure compatible with pipes with diameters ranging from DN50 to DN400. To accommodate this diameter range, the system features two categories of perforated metal bands, one suitable for diameters between DN50 and DN150, and another for diameters between DN200 and DN400, thus allowing for proper matching to the target sizes.
[0014] The collar assembly consists of using a perforated metal band, adjustable to the diameter of the pipe, which is fixed to the main body by means of a locking mechanism consisting of a self-locking nut, ensuring structural rigidity and stability of the fixation. The band is guided by a specially developed cradle and shaft system, facilitating precise adjustment to the diameter of the target pipe.
[0015] The seal between the collar and the piping is ensured by an EPDM elastomer element, in accordance with ABNT NBR 7676, which makes the sealing contact without displacement of the element during assembly, ensuring efficient tightness even under conditions of temperature or pressure variation. The collar body is equipped with a high-resistance three-way valve, allowing for branch connections at different points in the piping system. Petition 870260039243, dated 04 / 28 / 2026, page 8 / 14 / 10
[0016] For securing the branch connections, the system features a coupling system compatible with polyethylene pipe branches up to 20 mm in outer diameter, which connects to the assembly via a coupling nut and a locking clamp, preferably made of POM (polyacetal) material. This configuration ensures compatibility with various types of piping materials used in hydraulic installations.
[0017] In addition, the device features permanent laser engraving containing manufacturing and traceability information, and reinforced stamping on the body that provides greater mechanical strength. Its assembly is carried out in such a way as to preserve the integrity of the elastomeric element's seal, even when tightening the locking system.
[0018] Thus, the combination of these characteristics gives the multidiameter tapping collar a constructive arrangement that allows for its versatile, resistant and safe installation, meeting applicable technical standards, guaranteeing compatibility, durability and ease of maintenance in water supply and sanitation networks.

[0024] It should be noted that these figures are merely representative and may present variations, as long as they do not deviate from what was initially required. Detailed description of the construction layout.
[0025] According to figure 2, the CONSTRUCTIONAL ARRANGEMENT IN MULTIDIAMETRAL INTEGRATED COLLAR, object of the present patent, consists of a collar assembly (1) formed by a three-way valve (2) and its fixing means on a tube (T).
[0026] The three-way valve (2) contains an internal sealing sphere, integral with a shaft (3) rotated by a socket (4), fixed to the shaft by means of a screw (5), its rotational opening and closing movement being limited by an arrow (6), confined between stops of the valve body (2) and the socket (4). Said valve (2) has a threaded upper port (7) on which a sealing disc (8) is seated, sealed with a cap (9), while at the rear it has a threaded rear port (10) in which a locking nut (11) is inserted, internally equipped with a locking claw (12) and a sealing ring (13).
[0027] The smooth lower way (14) integral with the lower part of the valve (2) is seated in an orifice (15) provided with an upper protrusion (16) and a lower sealing element (17) contained in the arched region (18) of a monobloc band (19), which subsequently has an elongated segment (19) that has orifices (21) containing respective lugs (22), while frontally it contains a smaller segment (23) from whose sides project bearings (24) provided with a housing (25).
[0028] The bearing housings (24) support the journals (26) of a claw shaft (27), which is centrally pierced by the upper end of a threaded rod. Petition 870260039243, dated 04 / 28 / 2026, p. 10 / 14 / 10 (28) fixed by nut (29), while the lower end has a threaded lower shaft (30).
[0029] For the installation of the tapping collar assembly (1) on the pipe (T), as illustrated in figure 1, the first crucial step is the careful cleaning of the surface of the pipe (T) itself, removing residues, dirt and encrustations. This procedure is essential to ensure that the lower sealing element (17) of the tapping collar assembly (1) has a perfect and flawless seal.
[0030] After cleaning, select the tapping collar assembly (1) with the strap size that corresponds to the diameter of the pipe (1) of the network and proceed with the installation by initially removing the nut (29) and the claw shaft (27) from the threaded rod (28), followed by positioning the arched region (18) of the monobloc strap (19) over the pipe (T), but already containing the smooth lower channel (14) inserted into the hole (15) containing the lower sealing element (17). Insert the threaded rod (28) into one of the holes (21), followed by insertion of the claw shaft (27), which rests on the respective hook (22) of the chosen hole (21), and the nut (29). After this, the strap (19) is bent around the tube (T), for subsequent insertion of the claw shaft (27) into the bearing housing (25) (24). With the collar (1) thus positioned on the tube, the nut (29) is tightened, applying a recommended torque of 80 N to ensure ideal fixation.
[0031] Before drilling the network, a leak test is performed. A test HDPE pipe is connected to the branch, always remembering to bevel the end of the pipe to avoid damaging the sealing ring (13). With a half-inch wrench inserted into the socket (4), the arrow (6) is positioned on the letter A (Supply). The hand pump is used to raise the pressure to 2.4 MPa. If there are no leaks in the sealing element (18), the network is ready for drilling under pressure.
[0032] To drill, remove the cap (9), attach the drilling tool to the 3 / 4 thread of the part, insert the drill bit manually and change the arrow (6) to the P (Drilling) position. As the valve (2) is in P mode, the ball allows the drill bit to pass through without damage. Rotate the tool clockwise until the tube (T) is fully drilled. Petition 870260039243, dated 04 / 28 / 2026, page 11 / 14 / 10
[0033] After drilling, raise the drill bit and, before removing the tool, you must change the arrow (6) to the S (Suppression) position. This blocks the water outlet while removing the equipment. Place the final cap (9) with manual tightening, reconnect the building branch and, finally, turn the arrow (6) to the A (Supply) position, so that water flows freely from the main network through the threaded rear channel (10), in which the supply pipe that derives from the connection must already be installed. Examples of concrete applications of the constructive arrangement
[0034] In one embodiment of the present CONSTRUCTIONAL ARRANGEMENT IN MULTIDIAMETRAL INTEGRATED TAKE-OFF COLLAR, the metal components of STAINLESS STEEL 304 such as three-way valve (2), CH ½ socket, internal sealing ball, shaft (3), flat head screw (5) M6-1.00 χ 12, arrow (6), cover (9), self-locking hexagonal coupling nut (11) M12-1.75, monobloc strap (19), claw shaft (27), threaded rod (28) M12-1.75 χ 124 and nut (29) and sealing ring (13).
[0035] The others are the sealing disc (8), lower sealing element (17) and sealing ring (Di = 19; W = 3), both made of elastomer (NBR 7676), while the locking claw (12) is made of polyacetal.
[0036] This descriptive report therefore dealt with a collar-type socket design, which, as we were able to demonstrate through the analysis carried out and the figures shown, presents numerous differences from conventional models available on the consumer market, in addition to constructive and functional technical characteristics that are completely different from those pertinent to the state of the art.
[0037] Due to the advantages it offers, and also because it has peculiar characteristics that fulfill all the requirements of novelty and originality in the genre, the present CONSTRUCTION ARRANGEMENT IN MULTIDIAMETRAL INTEGRATED SOCKET COLLAR meets the necessary conditions to deserve protection as a Utility Model. Petition 870260039243, dated 04 / 28 / 2026, page 12 / 14 / 10
[0038] Obviously, it will be perceived that while the above has been described by way of illustrative example, all other modifications and variations made to this constructive arrangement, in the form that would be apparent to those skilled in the art, are considered within the broad scope and reach of this Utility Model, as per the claims below.
