Welded Stainless Steel Tube for Pressure Purposes
EN 10217-7

Material: 304, 304L, 316L

Welded Stainless Steel Tube

Apart from the regular tubes, YC INOX also provides tubes for peculiar purposes. The EN 10217-7 welded stainless steel tubes for pressure purposes are outstanding tubes made of durable materials such as 304, 304L, and 316L stainless steels. Buyers may choose the suitable diameter as well as thickness as the physical variables according to their machining demands.

There are 19 sets of thickness values. Each thickness value has its own corresponding outside diameter value, and those values are shown in the table. Buyers may refer to the table in this page. With different combinations of diameters and thicknesses, the corresponding tolerances are not the same.

It is worth mentioning that, with different choices of the OD and the corresponding thickness values, the tolerance values are also different. Please read the tolerance table carefully before the purchase. Besides the pipe specifications, buyers are also allowed to choose their packing methods for the tubes. There are steel crate and bundle packaging methods.
