Carbon steel piping is a durable material made from carbon steel, a steel alloy with iron and carbon. Because of its strength and ability to withstand stress, it is used in a variety of heavy-duty industries like infrastructure, ships, distillers, and chemical fertilizer equipment. Some of the most common uses of carbon steel tubing are Building foundations, Transporting natural gases or oil, Boiler and condenser tubes, Transporting wastewater, Chemical Processing, High-pressure applications, Transporting sewage, Bollard construction, Shipbuilding, Shoring, Trash enclosures, Distillers, OEM applications etc

Mild steel welded tube

2> The welded pipe production line needs at least 7 sets of equipment, such as planing machine, pre-bending machine, forming machine, hydraulic testing machine, pre-welding machine, internal welding machine, external welding machine. the line adopts computer PLC control and famous brand machine which greatly improve efficiency of production.

According to different welding technique, there are straight seam, spiral seam etc, the basic production process is : Raw material uncoiling - leveling - end shearing and welding - looper - forming - welding - internal and external weld bead removal - pre-correction - induction heat treatment - sizing and straightening - eddy current testing - cutting - hydraulic inspection - pickling - final inspection (strict control) - packaging - shipment.
