Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipes, in particular to a wear-resistant and bend-resistant stainless steel pipe. Background Art

[0002] Stainless steel pipe is a hollow, long, round steel. It is widely used in the fields of industry, construction, urban infrastructure, and electric heating, especially in the field of urban heating in urban infrastructure, because of its excellent corrosion resistance, good heat resistance, high strength and toughness, beautiful appearance and easy cleaning, environmental protection, recyclability and long service life.

[0003] When stainless steel pipes are used in conjunction with urban heating, most of them are pre-buried underground. Because there is no protective mechanism on the surface of the stainless steel pipes to protect them from bending and collision, the stainless steel pipes will bend and deform when squeezed and collided by ground cars or large equipment, which reduces the service life of the stainless steel pipes.

[0004] In order to overcome the above-mentioned defects, prior art 1 (application number CN202323211969.7, Chinese patent application date 2023-11-27) is a wear-resistant and bend-resistant stainless steel pipe. The setting of the thread makes it easier for users to connect the stainless steel pipe with other pipe fittings. The setting of the steel strip can increase the strength and rigidity of the stainless steel pipe, so that it can better resist the action of external forces. It can also effectively prevent the stainless steel pipe from deforming when subjected to external loads, so that it maintains its original shape and size stability.

[0005] Although the existing technology can achieve anti-bending and anti-collision protection for stainless steel pipes, when the stainless steel pipes are conveying materials, because there is no anti-friction mechanism on the inner wall of the stainless steel pipes to provide anti-friction protection for the inner wall of the stainless steel pipes, the inner wall of the stainless steel pipes will be worn after conveying materials for a long time, thereby reducing the service life of the stainless steel pipes.

[0006] Therefore, we proposed that wear-resistant and bend-resistant stainless steel pipes can solve the above problems well. Utility Model Content

[0007] The purpose of the utility model is to provide a wear-resistant and bend-resistant stainless steel pipe to solve the problem raised in the above background technology that when stainless steel pipes are used in conjunction with urban heating in the current market, most of the stainless steel pipes are pre-buried underground. Because there is no protective mechanism on the surface of the stainless steel pipe to protect the stainless steel pipe from bending and collision, the stainless steel pipe will bend and deform when squeezed and collided by ground cars or large equipment, thereby reducing the service life of the stainless steel pipe.

[0008] To achieve the above object, the utility model provides the following technical solution: a wear-resistant and bend-resistant stainless steel pipe, comprising a stainless steel pipe body and a threaded joint, wherein the two threaded joints are symmetrically arranged at the upper and lower ends of the stainless steel pipe body;

[0009] It also includes: the interior of the stainless steel pipe body is connected with a sealing sleeve through a sealing gasket, and the upper and lower ends of the sealing sleeve extend through and extend to the outside of the upper and lower ends of the stainless steel pipe body, and the upper and lower ends of the stainless steel pipe body are penetrated and installed with positioning plates, and the two positioning plates have the same structure, and are positioned with bolts, and the diameter of the positioning plates is larger than the diameter of the stainless steel pipe body.

[0010] Preferably, a circle of reinforcing ribs is positioned and installed on the inner side of the two positioning plates, and the circle of reinforcing ribs is arranged at equal intervals, and the inner side of the circle of reinforcing ribs corresponds to the stainless steel pipe body.

[0011] Preferably, three positioning blocks are mounted on the inner sides of the two positioning plates by screws, the three positioning blocks are all in an arc shape, and the inner sides of the three positioning blocks are fitted and connected to the outer side wall of the stainless steel pipe body.

[0012] Preferably, three mounting plates are welded and installed on both the upper and lower sides of the sealing sleeve, and the interiors of the three mounting plates are grooved and positioned and installed on the outer side wall of the stainless steel pipe body by positioning bolts.

[0013] Preferably, the inner side wall of the sealing sleeve is coated with a wear-resistant layer, and the wear-resistant layer is made of epoxy resin material.

[0014] Preferably, the outer side of the wear-resistant layer is coated with a protective layer, and the protective layer is made of polyurethane material.

[0015] Preferably, the outer side of the protective layer is coated with an anti-permeation layer, and the anti-permeation layer is made of nano-particle material.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] (1) A positioning plate is provided, and the positioning plates are fixedly installed at the upper and lower ends of the stainless steel pipe body, and then a circle of reinforcing ribs are positioned and installed at equal intervals on the inner side of the two positioning plates. At the same time, the stainless steel pipe body is located on the inner side of a circle of reinforcing ribs. The stainless steel pipe body used can be positioned and protected by a circle of reinforcing ribs, so as to avoid the stainless steel pipe body from being deformed and bent due to the squeezing of ground vehicles or large equipment during later transportation and use, thereby improving the service life of the stainless steel pipe body;

[0018] (2) Furthermore, three arc-shaped positioning blocks are installed on the inner sides of the two sealing sleeves by screws, and then the stainless steel pipe body is connected to the inner sides of the three arc-shaped positioning blocks. This can enhance the friction between the stainless steel pipe body and the positioning plate, thereby preventing the stainless steel pipe body and the positioning plate from loosening and falling off during use, thereby improving the connection stability between the stainless steel pipe body and the positioning plate.

[0019] (3) A sealing sleeve is provided, and a sealing sleeve is connected to the inner side of the stainless steel pipe body through a sealing gasket, and then three mounting plates are positioned and fixed to the inner side wall of the stainless steel pipe body through three positioning bolts on the outer side of the sealing sleeve. The material can be transported through the sealing sleeve to avoid the material directly contacting the stainless steel pipe body and causing friction damage, thereby improving the service life of the stainless steel pipe body;

[0020] (4) A wear-resistant layer is provided. The inner wall of the sealing sleeve is coated with a wear-resistant layer. Since the wear-resistant layer is made of epoxy resin material, a tough protective film can be formed on the surface of the sealing sleeve, effectively preventing corrosion and wear of the sealing sleeve, thereby increasing the service life of the sealing sleeve;

[0021] (5) Furthermore, by coating the inner side of the sealing sleeve with a protective layer and an anti-permeation layer, a soft and tough protective film can be formed on the surface of the steel pipe through the protective layer. Not only can the weather resistance, water resistance and chemical corrosion resistance of the sealing sleeve itself be improved through the protective layer, but the anti-permeation performance of the sealing sleeve itself can also be improved through the anti-permeation layer, thereby increasing the service life of the sealing sleeve itself.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] This utility provides the following technical solutions:

[0031] In order to solve the problem that the existing stainless steel pipe body 1 does not have a protective mechanism on its surface to protect the stainless steel pipe body 1 from bending and collision, which may cause the stainless steel pipe body 1 to bend and deform when squeezed and collided by a ground car or large equipment, the following embodiment is disclosed:

[0032] The stainless steel pipe body 1 and the threaded interface 2, wherein the two threaded interfaces 2 are symmetrically arranged at the upper and lower ends of the stainless steel pipe body 1;

[0033] It also includes: the interior of the stainless steel pipe body 1 is connected with a sealing sleeve 3 through a sealing gasket, and the upper and lower ends of the sealing sleeve 3 extend through and extend to the outside of the upper and lower ends of the stainless steel pipe body 1, and the upper and lower ends of the stainless steel pipe body 1 are penetrated and installed with positioning plates 4, and the two positioning plates 4 have the same structure, and the diameter of the positioning plate 4 is larger than the diameter of the stainless steel pipe body 1.

[0034] A circle of reinforcing ribs 5 is installed on the inner side of the two positioning plates 4, and the circle of reinforcing ribs 5 is arranged at equal intervals, and the inner side of the circle of reinforcing ribs 5 corresponds to the stainless steel pipe body 1. Three positioning blocks 6 are installed on the inner side of the two positioning plates 4 by screws. The three positioning blocks 6 are all arc-shaped, and the inner sides of the three positioning blocks 6 are fitted and connected to the outer wall of the stainless steel pipe body 1.

[0035] like Figure 1-Figure 4 As shown, when the stainless steel pipe body 1 is pre-buried in the ground for material transportation, the positioning plates 4 arranged on both sides of the stainless steel pipe body 1 will position and protect the stainless steel pipe body 1 through a circle of reinforcing ribs 5, thereby preventing the stainless steel pipe body 1 from being deformed and bent due to the squeezing of ground vehicles or large equipment during later transportation and use, thereby improving the service life of the stainless steel pipe body 1;

[0036] At the same time, the three arc-shaped positioning blocks 6 arranged on the inner sides of the two positioning plates 4 can also increase the friction between the stainless steel pipe body 1 and the positioning plates 4, avoiding the loosening and falling off of the stainless steel pipe body 1 and the positioning plates 4 during use, thereby improving the friction between the stainless steel pipe body 1 and the positioning plates 4.

[0037] The second embodiment is different from the first embodiment in that the anti-friction performance of the stainless steel pipe body 1 itself can be improved by the sealing sleeve 3, thereby increasing the service life of the stainless steel pipe body 1.

[0038] Three mounting plates 11 are welded and installed on the upper and lower sides of the sealing sleeve 3, and the interiors of the three mounting plates 11 are grooved and positioned on the outer wall of the stainless steel pipe body 1 by positioning bolts 7. The inner wall of the sealing sleeve 3 is coated with a wear-resistant layer 8, and the wear-resistant layer 8 is made of epoxy resin material.

[0039] The outer side of the wear-resistant layer 8 is coated with a protective layer 9 made of polyurethane material. The outer side of the protective layer 9 is coated with an anti-penetration layer 10 made of nano-particle material.

[0040] like Figures 1-6 As shown, when the stainless steel pipe body 1 is conveying materials, the sealing sleeve 3 that is sealed and connected on its inner side can convey the materials, avoiding the phenomenon that the stainless steel pipe body 1 is in direct contact with the materials and causing wear and reducing the service life. Then, the wear-resistant layer 8 coated on the inner side of the sealing sleeve 3 can improve the corrosion resistance and wear resistance of the sealing sleeve 3 itself. Finally, the protective layer 9 and the anti-permeation layer 10 can also improve the chemical corrosion resistance and anti-permeation performance of the sealing sleeve 3 itself, thereby improving the service life of the sealing sleeve 3 itself.
