ERW / SSAW / LSAW Offshore / Structure Steel Pipe with Big Diameter
Bangdong Supply ERW Black Steel Pipes,Hot Rolled ERW Steel Pipe,Steel Welded ERW Pipe.We also offer cold-drawing for pipes with the diameter and wall thickness required for use in boilers, superheaters, condensers, heat exchangers, automobile production and several other industrial applications.
Our Seamless Pipe manufacturing process involves the following steps:
Transformation of raw materials into steel bars (Electric arc furnace, ladle furnace, vacuum degassing and continuous casting processes)
Transformation of steel bars into mother pipe, which is manufactured in different types of rolling mills
Each product is manufactured in accordance with customer specifications, including heat treatment for more demanding applications. Our pipes are threaded and undergo non-destructive testing before delivery to the customer.
Our manufacturing facilities perform three types of welding processes:
Electric Resistance Welding: During ERW, a high frequency electrical current is transmitted to the material by means of copper sliding contacts so that the abutting edges initiate fusion as they come into contact.
Longitudinal Submerged Arc Welding: In LSAW, the butt joint of the pipe is welded in at least two phases, one of which is on the inside of the pipe. The welds are made by heating with an electrode arc between the bare metal electrodes. Pressure is not used. Filler metal for the welds is obtained from the electrodes.
Spiral Submerged Arc Welding: Spiral SAW allows large diameter pipes to be produced from narrower plates or skelps. During this process, the weld pool is protected against oxidation by a flux produced from the electrode fed separately onto the weld.
