Application space and development trend of stainless steel pipe!

   Stainless steel pipes are mainly used in petrochemical, nuclear power engineering, seawater desalination, sewage treatment, garbage treatment, marine engineering and other fields. With the continuous improvement of people's living standards, the advantages of stainless steel pipes such as beauty, non rust, high quality, strong applicability and recyclability will increase their consumption, especially in the field of green buildings Guardrails and stainless steel drinking water pipes will usher in greater market space, and the demand proportion will be further expanded.

Stainless steel pipe itself has the following advantages !

  Stainless steel tube has high heat transfer coefficient. The heat transfer performance of stainless steel pipe is realized through its unique ultra-thin wall steel pipe. Ultra thin wall steel pipe is a kind of thin-walled pipe with continuous tangent between large and small arcs and corrugated internal and external shapes.

  Stainless steel pipe is very high temperature resistant. Although the wall of stainless steel pipe is thin (0.5-0.8mm), the unidirectional failure pressure of stainless steel pipe measured in the experiment is generally about 20MPa. In fact, it is safe to control the medium pressure below 6.4Mpa. At the same time, it can adapt to higher working temperature up to 450 degrees, which has obvious advantages over ordinary pipes.

  Stainless steel pipe has strong anti scaling and descaling function, corrosion resistance and long service life; In the process of using the pipeline, it undoubtedly greatly reduces the cost for us.

 Precautions during welding of stainless steel pipe !

Before welding, the stainless steel composite layer shall be removed at the joint by machining according to the requirements of product drawings. The butt weld shall be provided with appropriate groove, and the oxide, rust, oil, moisture and other substances affecting the welding quality shall be removed by wire brush or grinding. Plastic coated thin-walled stainless steel pipe shall be selected when it is used as the lower pipe, which can avoid acid-base corrosion on the outer wall of the pipe or damage to the pipe by sharp and hard sundries. Other wrapping materials can also be used as anti-corrosion measures, such as wrapping two layers of polyethylene tape.

The application of stainless steel water pipe is becoming a global development and application.

As early as more than ten years ago, some developed countries such as the United States, Europe and Japan have abandoned traditional pipes such as galvanized steel pipe, plastic pipe and copper pipe and replaced them with stainless steel pipes. In 1999, the Tokyo water authority used SUS316 stainless steel bellows as the standard material. Friends in Japan should find that the tap water on the street is ready-made and stainless steel pipes. This ready to drink water tastes sweet and greatly improves the water quality.

In 2003, the latest edition of water and housing standard of American International Standards Committee again included this point, indicating that the use of stainless steel water pipes has been recognized by the U.S. government. Other countries such as Malaysia, the Philippines, South Korea, Singapore, Thailand and Taiwan have also confirmed this standard. Ford stadium is a $300 million new stadium in Detroit. Its main water supply system includes direct drinking water pipes at each point of sale, which are made of 304 stainless steel. The United States is a big market for steel pipe products in the world. 30% of its steel pipes and 70% of its stainless steel pipes need to be imported from abroad.
