ERW welded pipe mechanical system will manufacture resistance high frequency straight seam welded pipe,, rectangular tube and steel piling, etc.
ERW pipe manufacture progress:
(1) we’ll check the fabric, and ensure the fabric is sweet.
(2)Cut the steel material, create it suitable the pipe.
(3)Bend the fabric, this step is facility for attachment.
(4)The machine can create the steel material to J than C, the last is O. that the pipe is spherical.

Applications:Used in mechanism,nested card instrumentality (pipe joints) with matching,,automobile and within the occasion wherever the high exactness,brightness,cleanness and mechanical properties of the tube ar needed

Specifications:Outside diameter ranges from four to sixty millimetre and wall thickness ranges from zero.5 to 7mm. exactness steel tubes ar delivered consistent with EN10305-4.Tolerance Table Of Steel Tube
