The pressure ratio of the spiral steel pipe on the gas pipeline also has a downward trend. For pipe diameter, pressure, and pressure ratio, it is necessary to carry out optimization calculations and comparisons. When the transmission volume is determined, after the pipe diameter, pressure, and press

The welding seam steel pipe of the spiral steel tube is longer than that of the straight-seam steel tube. If the tube length is L, the welding seam length is L/cos(θ). The vast majority of steel pipe defects are concentrated in the weld and heat-affected zone. The long weld means that the probabilit

Project Location: Indonesia.Product: Large Diameter Steel Pipe.Material: Stainless Steel Application: Heat Exchange project.Arrival time: 07.10.2022.The steel pipes have arrived in Indonesia and were put into project use. Many cooperations have given the customer full confidence in THREEWAY STEEL.

The anti-corrosion of plastic-coated steel pipes was developed from the earliest inner and outer polyethylene. Due to adhesion problems, it developed into inner and outer epoxy, but the outer epoxy layer was not resistant to bumping. Later, it developed into the third generation of inner epoxy and o
