Main Application Areas Of Stainless Steel Pipe

- Nov 29, 2018-

    Stainless steel welded pipes are mainly used in heat exchanger pipes, fluid pipes, pressure pipes, mechanical structure pipes, urban landscape, and other industries. The demand for stainless steel welded pipes for industrial use is relatively high, and the production process is mature.

 

       From the point of view of domestic stainless steel pipe products, austenitic steel is the main type of steel; product varieties are: seamless steel pipe including cold-drawn pipe, cold-rolled pipe, hot extrusion pipe, centrifugal casting pipe, spinning pipe;

    

      Welded pipes include plasma welding, argon arc welding, submerged arc welding, light speed welding and high frequency welding. The stainless steel pipes produced basically cover the varieties and specifications of international standards.

 

      The specifications and varieties of stainless steel special-shaped pipes are more than 100 kinds. The products are used in many fields of industry and civil.

     

      The processing range and application environment of stainless steel pipes of different materials are different. For example, 304 stainless steel pipes can be used in heat exchangers, condensers, pressure vessels and other equipment industries.

The 409/436 pipe can be used in the field of automobile exhaust system.

 

Why can stainless steel pipes be used in these fields?

 

    1. 201 stainless steel pipes have general corrosion resistance, mostly decorative pipes, such as stainless steel guardrails, stainless steel handrails, stainless steel anti-theft windows, etc. are basically 201 materials.


    2. 304 stainless steel pipes have strong corrosion resistance, heat resistance and low temperature resistance. They are basically used for decoration and mechanical pipes. Because of their strong corrosion resistance, 304 stainless steel pipes are used as handrails, guardrailings, anti-theft windows and so on in some coastal areas.

      The door decorative pipe, and its heat resistance also shaped its deep processing performance, such as punch, bending circle, basically choose 304 stainless steel pipe.


     3. 316 stainless steel pipes have better corrosion resistance than 304, and better high temperature resistance than 304. They are generally used in mechanical pipes, such as some boilers, high temperature processing machinery accessories, aviation, bearings, chemical industry and so on.

 

Application of stainless steel pipe in petrochemical industry

 

      Petrochemical industry, including fertilizer industry, the demand for stainless steel pipe is extremely high, the industry mainly uses stainless steel seamless pipe, specifications include: 304, 321, 316, 316L, 347, 317L, etc., outer diameter in ¢18-¢610 Left and right, wall thickness in the 6mm-50mm around (generally selected specifications in the φ159mm above the medium and low pressure conveyor pipeline), the specific application areas are: furnace pipe, material conveyor pipe, heat exchanger tube and so on.

 

        For example:


      Heat resistant stainless steel pipes are mainly used for heat exchange and fluid transportation.

Duplex stainless steel pipes are mainly used in chemical and fertilizer heat exchanger and fluid pipe market because of its high strength, stress resistance, corrosion resistance and economy.

     

       Stainless steel bushing, stainless steel non magnetic drill collar used in oilfield drilling and production, high resistance CO, CO2 and Cl- corrosion super ferrite stainless steel Cr13, Cr25 and other oil casing.
