Technical Maintenance of Stainless Steel Pipe Coil

The material of the stainless steel pipe coil undergoes elastic and plastic strain under the action of flow force. If the stress is large enough, the stainless steel pipe coil will break. Strength is the ability of a material to resist deformation and fracture, while plasticity represents the degree of total plastic deformation at fracture. Therefore, when uniaxially stretched, yield strength and tensile strength are strength indicators, while elongation and area shrinkage are plastic indicators; toughness is the ability of the material to absorb energy in the entire process of plastic deformation and fracture. The real strain curve is represented by the area between plastic deformation and fracture.

1. Characteristics of stainless steel pipe coils in all aspects

In the building water supply piping system, since galvanized steel pipes have ended a glorious history of a hundred years, various new plastic pipes and composite pipes have developed rapidly, but there are still some deficiencies in various pipes to varying degrees, and they are far from fully adaptable to water supply pipes. The needs of the system and the national requirements for drinking water and related water quality. Therefore, relevant experts predict that the construction water supply pipes will return to the era of metal pipes. According to foreign application experience, thin-walled stainless steel pipe is identified as one of the comprehensive and good pipes in metal pipes.

In order to popularize hexagon tubing and reduce costs, solve the technical problem of "high-diameter-wall ratio high-density" thin-walled stainless steel pipes, so that stainless steel pipes have been popularized and applied and developed rapidly. If a pipeline can be popularized and applied, localization is indispensable. Stainless steel pipes are reliable, hygienic, environmentally friendly, economical and applicable. The thin-walled pipes and the successful development of new reliable, simple and convenient connection methods make them have more irreplaceable advantages for other pipes, and their applications in engineering will be more and more. The use will become more and more popular, and the prospects are promising.

2. Technical maintenance and maintenance of stainless steel pipe coil

The parts with weak corrosion resistance in the passive film on the surface of the stainless steel pipe coil will form a pitting reaction due to the self-excited reaction, resulting in the formation of small holes, coupled with the proximity of chloride ions, forming a strong corrosive solution, accelerating the corrosion reaction speed. There are also intergranular corrosion cracking inside the stainless steel, all of which destroy the passive film on the surface of the stainless steel plate. Therefore, the stainless steel surface must be regularly cleaned and maintained to maintain its gorgeous surface and prolong its service life.

(1) The thicker the wall thickness of the stainless steel pipe coil, the more economical and practical it is, and the thinner the wall thickness, the higher the processing cost.

(2) The process of stainless steel pipe coil determines its limited performance. Generally, seamless tube stainless have low precision: uneven wall thickness, low brightness on the inside and outside of the tube, high cost of sizing, and there are pits and black spots on the inside and outside that are not easy to remove.

(3) The inspection and shaping of the stainless steel pipe coil must be processed offline. Therefore, it reflects its superiority in terms of high pressure, high strength, and mechanical structural materials.
