347H Stainless Steel Tube

347H Seamless Stainless Steel Tube

347H Stainless Steel erw Tubes
347H stainless steel tube is made out with acclaimed modest tube mills. Stainless steel tubes are made using Tungsten-Inert-Gas (TIG) welding process on strips of specified widths continuously to form the strips into tubular. Then the edges of the strips are heated and compounded together under a well protected atmosphere of argon gas through a non-consumable electrode without the addition of any filler metal. The welding process is persistently controlled by sophisticated electronic devices that maintain flawless arc stability and direction in the magnetic field.
