Fluid pipe is a kind of steel pipe with hollow cross-section and no weld seam from end to end. Steel pipe has a hollow cross-section, a large number of used as a pipe to transport fluids transport oil, natural gas, gas, water

Petroleum casing is a steel pipe used to support the walls of oil and gas wells to ensure that the drilling process is carried out and that the entire well operates properly after completion. Several layers of casing are used for each

Galvanized special-shaped steel pipes can be divided into oval special-shaped steel pipes, triangular special-shaped steel pipes, hexagonal special-shaped steel pipes, rhombus special-shaped steel pipes, octagonal special-shaped steel pipes, semi-circular special-shaped steel pipes, unequal hexagonal special-shaped steel pipes, and five-petal plum blossom shaped

Galvanized square pipes are generally made of welded square pipes or seamless square pipes as raw materials through hot-dip galvanizing or electro-galvanizing processes. Hot-dip galvanized square tubes are square tubes made by curling and welding steel plates or steel strips in a

Galvanized round pipe is a metal pipe manufactured into a circular shape. The surface is galvanized to increase the corrosion resistance of the steel pipe and extend its service life. Galvanized round pipes are widely used in construction, mechanical engineering, manufacturing and

Longitudinal Submerged Arc Welding (LSAW / SAWL) is a specific welding technique used in pipe production where the finished product requires a particularly high wall thickness due to high internal or external pressures.The LSAW pipe diameter range is larger than ERW (Electric

High-pressure fertilizer pipe is a high-quality carbon steel and alloy steel seamless pipe, mainly used for working temperature of -40~400℃, working pressure of 10~32 MPa chemical equipment and pipelines, suitable for transporting synthetic ammonia, urea, methanol and other media. Execution standard: GB

low temperatures seamless pipe is a steel pipe product used in special environment. The main requirement in the low temperature environment (usually below -45 ℃) finished steel pipe with good impact toughness. Ensure that no low-temperature brittle fracture occurs in the process

Petroleum cracking pipe is a special pipeline product widely used in the petroleum refining industry. It is mainly used to transport high-temperature and high-pressure cracking products in the petroleum cracking process, such as naphtha, gasoline, diesel, etc. It has the characteristics of
