Large Diameter Stainless Steel Pipes

Besides regular size stainless steel pipes, YC INOX provides large diameter stainless steel pipes to meet certain customer needs. Customers can choose the diameters and thicknesses as physical variables of the JIS G3468 and CNS 13517 pipes based on their needs and requirements.

The JIS G3468 and CNS 13517 large diameter pipes produced by YC INOX are solid pipes made of good materials, including 304, 304L, and 316L stainless steels.

In regard to the size specifications of JIS G3468 and CNS 13517 pipes, buyers can choose the most fitting nominal diameters, as well as outside diameters and nominal wall thickness according to their machining requirements. In addition, there is “other common thickness” as another important variable. With distinct combinations of diameters and wall thickness, the corresponding tolerances and features are not identical. You may find relevant information on this page.

Buyers may select an appropriate packaging solution for the shipment according to their budget plans. There are mainly two choices provided: Bundle and steel crate packages.
