Large-diameter stainless steel seamless tubes 
The main features of the stainless steel seamless tubes produced by our company
are large, special, excellent and new. The diameter can be produced from Φ168 to
Φ711mm and the wall thickness can be 3-70mm; in the aspect of materials, it can
not only produce commonly-used 304, 316, 321, 310 and other series of products
according to national standard, American standard, Japanese standard and
European standard, but also produce seamless tubes of duplex steel, 904L, high
nickel Inconel600, INCOLOY800 and other materials according to the standards at
home and abroad; another feature is that it can produce stainless steel seamless
tubes of high technology and high quality used in nuclear power, thermal power,
petrochemical and other aspects, and has a very good performance. In the aspect of
new product development, it has developed steels used in 1%Ni austenitic stainless
steel tubes, mastered the production process of ultra-thin, large-diameter and high-
precision tubes, etc. Therefore, it has a strong competitiveness in the stainless steel
seamless tube industry.
