Welded Tubing for Gerenal Purpose

Having been cultivating in the field of stainless steel tubes, YC INOX is skilled in the manufacture of tubes for a variety of different applications. The welded austenitic sanitary tubing technology developed by YC INOX provides tubes for boilers, heat exchangers, and general service tubing purposes.

YC INOX adopts the best materials to make the tubes in order to achieve the best quality for customers’ industrial performance. The tubes are made of 304, 304L, and 316L stainless steels, offering great durability. Purchasers may choose the suitable diameter as well as thickness according to their industrial requirements. These two variables are critical and decisive to customers’ applications. Each thickness value has its own corresponding outside diameter value, and those values are shown in the table. Purchasers may refer to the table in this page.

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.
