Description

Technical Field

[0001] The utility model relates to a saddle-shaped anti-corrosion pipe clamp for pipeline support, belonging to the field of pipeline anti-corrosion supports. Background Art

[0002] Corrosion under pipe supports (CUPS), also known as touchpoint corrosion (TPC), is a leading cause of pipeline failure. All types of pipe supports create crevices, trapping water near the pipe surface. This corrosion can quickly destroy the anti-corrosion paint and damage the pipe wall. Coastal areas, particularly those with high atmospheric salt content and chloride ion concentrations in rainwater, can cause severe localized corrosion in these areas. Traditional neoprene and other rubber underlayments, originally used for pipeline corrosion protection, while intended to prevent crevice corrosion, actually exacerbate it, leading to significant damage.

[0003] If these issues are not addressed, the entire pipeline could fail and require replacement. Furthermore, this area is difficult to inspect and maintain, presenting significant risks. Currently, many companies are experiencing severe corrosion failures in this area, impacting not only production operations but also human safety, potentially leading to catastrophic consequences. Utility Model Content

[0004] The purpose of the utility model is to provide a saddle-shaped anti-corrosion pipe clamp for pipeline support; by eliminating crevice corrosion between the pipeline and the bracket, the service life of the pipeline is ensured to be longer and safer, and the clamp has the advantages of being durable and easy to maintain and inspect.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a saddle-shaped anti-corrosion pipe clamp for pipe support, characterized in that it includes a pipe clamp body, an anti-corrosion pad and a bolt, the pipe clamp body includes an upper pipe clamp and a lower pipe clamp, the upper pipe clamp and the lower pipe clamp have the same shape, both are semicircular saddle-shaped structures, the saddle-shaped structures of the upper pipe clamp and the lower pipe clamp extend horizontally at both ends to form connecting seats at both ends, and the connecting seats at both ends are each provided with a through hole; the bolt is composed of a stud and a nut; the upper pipe clamp and the lower pipe clamp are clamped on the pipe in a snap-on manner, and the studs are passed through the through holes of the connecting seats at both ends and the nuts are tightened so that the upper pipe clamp and the lower pipe clamp are fastened and installed on the pipe; the annular inner side surface of the pipe clamp body is evenly provided with a plurality of anti-corrosion pads, and the anti-corrosion pads are used to isolate the pipe clamp body from direct contact with the pipe.

[0006] Preferably, the anti-corrosion pad includes an upper anti-corrosion pad and a lower anti-corrosion pad, and the upper anti-corrosion pad and the lower anti-corrosion pad are both I-clamp structures, which are respectively adapted to be installed on the annular inner side surfaces of the upper pipe clamp and the lower pipe clamp.

[0007] Preferably, the anti-corrosion pad is a semi-cylindrical structure, and a groove is provided on the plane of the side of the semi-cylinder. The groove is used to clamp the anti-corrosion pad on the pipe clamp body, and the anti-corrosion pad is detachably connected to the upper pipe clamp and the lower pipe clamp.

[0008] Preferably, the pipe clamp body is made of any one of carbon steel, stainless steel, and chrome-molybdenum steel, and the surface of the pipe clamp body and the bolt are coated with an anti-corrosion coating.

[0009] Preferably, the bolts are of larger sizes as the size of the pipeline increases.

[0010] Preferably, the anti-corrosion pad is made of high-strength thermoplastic engineering plastic.

[0011] Preferably, the upper anti-corrosion pads and the lower anti-corrosion pads are both middle two anti-corrosion pads with height dimensions higher than the anti-corrosion pads on both sides.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) By combining the pipe clamp body and the anti-corrosion pad, the gap between the pipe and the pipe clamp can be effectively eliminated, which is conducive to water evaporation and avoids aggravated corrosion in humid conditions. At the same time, it prevents galvanic corrosion between the different metals of the pipe and the pipe clamp.

[0014] (2) The anti-corrosion pads are made of high-strength thermoplastic engineering plastics to meet the various requirements of different applications. They are suitable for high-temperature and high-load applications and can meet the requirements of extreme environments. This material has excellent compressive strength and extremely low friction coefficient, ensuring the required reliability and long life of the pipeline.

[0015] (3) The anti-corrosion pad adopts an I-clamp structure to minimize the contact area between the pipeline and the pipe clamp, thereby eliminating the generation of gaps and effectively preventing the formation of corrosion.

[0016] (4) The upper anti-corrosion pads and the lower anti-corrosion pads are designed so that the middle two anti-corrosion pads are higher than the anti-corrosion pads on both sides, so that the pipeline can be in close tangential contact with all the upper anti-corrosion pads and the lower anti-corrosion pads to ensure the required stability of the pipeline.

[0017] (5) By installing a detachable anti-corrosion pad on the pipe clamp body, it is easy to maintain, inspect and replace. At the same time, since there is no need to replace the pipe clamp as a whole, it also greatly saves costs.

[0018] (6) The anti-corrosion pad is an integrally formed structure, which not only has a low manufacturing cost but also has high overall strength and a relatively long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example: See Figure 1-2 , a saddle-type anti-corrosion pipe clamp for pipe support, characterized in that: it includes a pipe clamp body 1, an anti-corrosion pad 2 and a bolt 3, the pipe clamp body 1 includes an upper pipe clamp and a lower pipe clamp, the upper pipe clamp and the lower pipe clamp have the same shape, both are semicircular saddle-shaped structures, the saddle-shaped structures of the upper pipe clamp and the lower pipe clamp extend horizontally at both ends to form connecting seats at both ends, and the connecting seats at both ends are each provided with a through hole 11; the bolt 3 is composed of a stud 31 and a nut 32; the upper pipe clamp and the lower pipe clamp are clamped on the pipe in a buckled manner, and the stud 31 passes through the through holes 11 of the connecting seats at both ends and then tightens the nut 32, so that the upper pipe clamp and the lower pipe clamp are fastened and installed on the pipe; a circular hole is formed in the middle of the structure combined with the upper pipe clamp and the lower pipe clamp to ensure the stable fixing performance of the pipe clamp; the bolt 3 connection is convenient for later disassembly and maintenance, and the nut 32 is two sets. After tightening the first nut, the second nut is threaded onto the same axis and tightened to lock the nut to prevent sliding.

[0024] Furthermore, a plurality of anti-corrosion pads 2 are evenly provided on the annular inner side surface of the pipe clamp body 1, and the anti-corrosion pads 2 are used to isolate the direct contact between the pipe clamp body 1 and the pipeline; the anti-corrosion pads 2 include an upper anti-corrosion pad and a lower anti-corrosion pad, and the upper anti-corrosion pads and the lower anti-corrosion pads are both I-clamp structures, which are respectively adapted to be installed on the annular inner side surfaces of the upper pipe clamp and the lower pipe clamp; the anti-corrosion pads 2 are semi-cylindrical structures, and a groove 21 is provided on the plane of the side surface of the semi-cylinder, and the groove 21 is used to clamp the anti-corrosion pads 2 on the pipe clamp body 1, and the anti-corrosion pads 2 are detachably connected to the upper and lower pipe clamps; in this way, after a period of time, when the upper and lower anti-corrosion pads are worn or aged, they only need to be removed from the upper and lower pipe clamps and replaced with new anti-corrosion pads 2, without replacing the entire pipe clamp, which is not only simpler to maintain, but also greatly saves material costs;

[0025] Furthermore, the pipe clamp body 1 is made of any one of carbon steel, stainless steel, and chrome-molybdenum steel, and the surfaces of the pipe clamp body 1 and the bolt 3 are coated with an anti-corrosion coating, which can effectively reduce the occurrence of corrosion, increase the service life of the pipe clamp body 1 and the bolt 3, and reduce replacement costs; the bolt 3 can be selected with a larger size according to the increase in pipe size; the anti-corrosion pad is made of high-strength thermoplastic engineering plastic, which has excellent compressive strength and extremely low friction coefficient; secondly, the anti-corrosion pad 2 is an integrally molded structure, with low manufacturing cost and high overall strength;

[0026] Furthermore, the upper anti-corrosion pads and the lower anti-corrosion pads are both the two middle anti-corrosion pads, and the height dimensions are higher than the anti-corrosion pads on both sides. The two middle anti-corrosion pads 2 bear greater force and are more susceptible to wear, and the large size has a longer service life; and when installed on the pipeline, the two middle anti-corrosion pads are subjected to greater force and have a greater deformation amplitude.
