Wear-resistant and corrosion-resistant stainless steel composite tube

Abstract

The invention belongs to the technical field of stainless steel tubes, and particularly relates to a wear-resistant and corrosion-resistant stainless steel composite tube. The stainless steel composite tube comprises a glass fiber rib and a composite resin layer, wherein the glass fiber rib is wound around the outer surface of a stainless steel tube body, the glass fiber rib is provided with prestress during winding, and the composite resin layer is arranged on the outer surface of the glass fiber rib. According to the tube, the glass fiber rib is wound around the outer surface of the stainless steel tube body and is provided with the prestress, so that the strength of the tube wall of the stainless steel tube body can be effectively improved; in addition, the prestress can offset the pressure generated by conveying of a high-pressure fluid, so that the reliability and the safety of the stainless steel composite tube during the conveying of the high-pressure fluid are ensured; the wearresistance and the corrosion resistance of the stainless steel composite tube can be remarkably improved by the composite resin layer on the outer surface of the glass fiber rib, so that the stability of the stainless steel composite tube in the using process is improved.

Description

technical field [0001] The invention belongs to the technical field of stainless steel pipes, and in particular relates to a wear-resistant and corrosion-resistant stainless steel composite pipe. Background technique [0002] Stainless steel pipe is a hollow long round steel material, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. [0003] In the prior art, in order to improve the wear resistance and corrosion resistance of stainless steel pipes, it is usually focused on improving the composition of stainless steel pipes. For example, the Chinese patent application number "CN201610662099.0" discloses a stainless steel pipe containing nano-titanium The composition of the stainless steel tube is: carbon 0.01-0.03wt%, nano-titanium 6.8-9.4wt%, cobalt 0.05-0.1wt%, sulfur 0.02-0.03wt%, tantalum 0.1-0.2wt%, tungsten 2.2 -3.2wt%, zirconium 1.45-1.55wt%, boro...

Problems solved by technology

However, this technical solution to change the composition of the existing stainless steel pipe encounters many obstacles in the cost of raw materials and production processes, and the increase in production costs and changes in the process make its promotion bring great disadvantages.

[0004] Another example is that the Chinese patent application number "CN201720233367.7" discloses a high-stability composite stainless steel pipe, including a stainless steel pipe body, a high-temperature resistant layer is fixedly connected to the inner surface of the stainless steel pipe body, and the stainless steel pipe body A rubber layer is fixedly connected to the outer surface of the rubber layer, and a spherical groove is opened inside the rubber layer, and a rubber protrusion is fixedly connected to the inner surface of the spherical groove, and a shock-absorbing ball is fixedly connected to the inner surface of the rubber protrusion. , the interior of the shock-absorbing ball is fixedly connected with a fixed ball, the upper surface of the rubber layer is fixedly connected with a flame-retardant layer, the outer surface of the flame-resistant layer is fixedly connected with a corrosion-resistant layer, and the corrosion-resistant layer The outer surface is fixedly connected with a wear-resistant layer, and the front and back of the stainless steel pipe body are fixedly connected with iron sheets, and a through hole is opened on the surface of the iron sheet; however, the manufacturing process of this stainless steel pipe is too complicated and cumbersome.
