Stainless steel welded pipe:The steel pipe which uses stainless steel strips as material or argon arc welder or ultrasonic welder or any other welding method to weld.
Square or rectangular welded pipe：The welded pipe that was made through forming round pipe and then welding,sizing and straightening it to be square or rectangular tube.
Special tube:The welded pipe that was made through forming round pipe and then welding,sizing and straightening it to be special tubes with different cross-section shape.
Galvanized welded pipe: some of small-diameter and thin galvanized pipe can be made through stainless steel tube mills.
Some people prefer to choose seamless welded pipe.However,both stainless steel welded pipe and seamless welded pipe have their own advantage and disadvantage.As science and technology developed, stainless steel welded pipe welding technology has been improved greatly and became more mature. Some manufacturers’ stainless steel welded pipes can rival with seamless welded pipes,it can be shaped like a seamless welded pipe.However,it’s more cost-efficient.So most people who don’t have too many requirements on the welded pipe will choose stainless steel welded pipe.Especially when Seko Machinery developed the weld bead rolling machine to remove the internal weld bead,weld bead grinding machine to remove external machine,bright annealing machine to release stress and strengthen the pipe,automatic welding tracking system to track the exact position of weld bead and then welding automatically,polishing machine to make tube surface roughness reach 500# -700#,anti-torque device to correct the position of the weld bead,eddy current flaw detector to detect the flaw of the pipe to ensure the high quality of the tube.
