Welded steel pipe,API5L,ERW pipe

Precise welded steel pipes are well used in a large number of domains like leisure products, constructions, sports facilities equipments, medical instrument, and also the furniture, vehicles, transportations.

All of our steel pipes are produced from the carbon and low carbon steel coils according to the American standard, Japanese standard, and other similar standards which suit on steel pipe fields.

Our steel pipes produced range is like follows:

Our diameter range: from 6.5mm to 114mm.

Thickness range: from 0.3mm to 6.0mm.

Manufacturing Process:

Uncoiler→Flattening→Shearing→End Welder→Spiral Accumulator→Edge milling machine→Inspect→Forming Machine→ HF welder→On Line Ultrasonic Testing→On line welding seam heat treatment→Air cooling water cooling→Sizing→Flying Saw Decides the ruler→Flattening test→overall dimensions inspection→ Measure length/weight→Marking→Coating→packing→Transportation..
