Steel Welded pipes are used in a wide array of applications largely because of their reliability, strength and non corrosive nature. These pipes are welded with over alloyed filler metals with nitrogen added to the shielding gas and thus leading to high pitting corrosion resistance as possible in the weld. These pipes are available according to the client''s requirements, in a wide array of dimension.

welded pipes are available as per the following specifications
