welded stainless steel

Eddy Current testing is a non-destructive testing method that utilizes an eddy current flow to detect a discontinuity in the weld area of the tubing.

Finish internal :
Tubes with diameter greater than or equal to 31.8 mm are internally cold worked (Internal weld beaded to tube surface).

A554 - A554-98e1 - Specification for Welded Stainless Steel Mechanical Tubing.A554 are typically used for stainless steel mechanical tube application

Electric resistance weld tubing (ERW) is a method of tubing production where slit coils of steel are put through a gradual cold forming operation

Tubing is generally used for structural purposes and the OD is an important and exact number.Tubing size is specified by OD and the wall thickness .
