Technical Field

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

[0002] Stainless steel pipe is a hollow, long, round steel bar widely used in industrial pipelines and mechanical components in the petroleum, chemical, medical, food, light industry, and instrumentation industries. Furthermore, its light weight, while maintaining the same bending and torsional strength, makes it widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used in furniture and kitchenware.

[0003] Existing stainless steel pipes are made of a single layer of metal, which makes them easily scratched or deformed due to friction or collision with external objects during use or transportation. In addition, the interior is easily corroded and damaged due to long-term contact with fluids.

[0004] In order to solve the above-mentioned shortcomings, reference can be made to the prior art (Chinese patent application number 201822160825.6, publication date 2018-12-22), which discloses a corrosion-resistant and high-temperature resistant stainless steel seamless pipe. By setting up a pipe body, a heat dissipation anti-collision plate, and a granite layer, the pipe body is sequentially provided with a granite layer, an anti-corrosion layer, a stainless steel pipe, a seamless steel pipe, an epoxy resin high-temperature resistant layer, and an antioxidant layer from the inside to the outside, thereby achieving the advantages of corrosion resistance and wear resistance.

[0005] Although existing stainless steel pipes can achieve the purpose of corrosion resistance and friction resistance, because there are multiple layers of steel pipes and granite layers inside, and the granite layer is in direct contact with the fluid, the overall weight of the pipe body increases, and the granite layer is prone to falling off under the influence of the fluid for a long time.

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

[0014] Furthermore, the inner side of the connecting port is adhered with anti-slip glue, and the two push blocks form an elastic structure through a spring.

[0015] Furthermore, a symmetrically arranged connecting block is welded on one side of the connecting disk away from the tube body, and a bayonet that matches the bayonet block is provided at the bottom end of the connecting block.

[0016] Furthermore, the connecting plate and the flange plate form a limiting structure through the connecting block and the connecting port, and the connecting block and the connecting port form a clamping structure through the clamping block and the clamping port.
