What is stainless steel pipe?
Stainless steel pipe（smls pipe） is a kind of hollow long round steel, according to its production method is divided into two categories: seamless pipe and welded pipe. It is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial transmission pipes as well as mechanical structural components. The production of a stainless steel pipe needs to go through many links, from raw materials into the warehouse to the finished product processing, etc., so in this production process of stainless steel pipe quality of those factors that affect it?
Stainless steel pipe quality factors affecting
1. Stainless steel pipe raw materials
The main raw material for the production of stainless steel pipe is what we often call steel strip, and raw steel strip also has a variety of distinctions, that is, there are advantages and disadvantages, just as there are refining furnace steel strip and reheat steel strip. Refining furnace steel strip, chromium, nickel and other metal elements content is stable, carbon, sulfur and other impurities content is low, so that if the use of steel strip raw material is good, the finished stainless steel tube will be better, the later use of the tube is not easy to rust.
2. Stainless steel pipe manufacturer's quality inspection standards
The manufacturer's quality inspection standards directly affect the quality of the pipeline project, and the quality of the pipeline project will also directly affect the quality of the product. Just like the pipeline welding with nitrogen internal protection. After adding nitrogen internal protection, white lines will appear in the weld seam. This is because the nitrogen is used to isolate the oxygen in the air during welding and oxygen-free welding, so that the pipe is not easy to crack or rust from the weld seam in later use. If you do not add nitrogen protection, the inner wall of the stainless steel pipe will appear black line, easy to burst or rust from the weld in later use, affecting the service life of the stainless steel pipe. In addition, if the quality control requirements are not strict, there will be a variety of quality problems such as poor roundness, surface strains, and bad brightness of round and square pipes.
3. Differences in actual pipe thickness
Among the factors affecting the quality of the pipe, the thickness or actual thickness is specifically mentioned, mainly because the actual thickness of the pipe will also affect the service life of the finished product. Generally the thicker the pipe of the same specification the more durable, so when buying stainless steel pipe, ask what the actual thickness is, because some labels will be different from the actual thickness to prevent future disputes caused by errors.
Stainless steel pipe is an economic section steel, is an important product in the steel industry, can be widely used in life decoration and industry, many people on the market for making stair handrails, window guards, railings, furniture, etc.. Because of its safe and reliable, health and environmental protection, economic and applicable, the thin wall of the pipe as well as new and reliable, simple and convenient advantages, stainless steel pipe in the engineering of more and more applications, the use of more and more popular.
