Welded steel pipe refers to a steel strip or steel plate that is bent and deformed into a circular or square shape and then welded into a steel pipe with seams on the surface. The blank used for welded steel pipe is steel plate or strip steel. According to the shape of the weld, it can be divided into straight seam welded pipe and spiral welded pipe.

Spiral steel pipe is a spiral seam steel pipe made of strip coil plate, extruded by constant temperature and welded by automatic double-wire submerged arc welding. The spiral steel pipe will send the strip into the welding pipe unit, roll through the multi-channel roll, the strip gradually rolled up to form a circular tube blank with an open gap, adjust the pressure of the extrusion roll, so that the weld gap is controlled in 1~3mm, and the two ends of the welding joint are flush.

Our oil pipeline steel is specially designed for oil and gas transportation, featuring high strength, corrosion resistance, and excellent weldability, making it suitable for harsh working environments and complex operating conditions in the petroleum industry.

Custom sizes and coating options are available to meet your project requirements.

As a core material in the field of fluid transportation such as oil and natural gas, API 5L GRB seamless steel pipes have become a key choice for ensuring the safety and efficiency of pipeline systems, thanks to their smooth, scratch-free internal and external surfaces. These steel pipes strictly comply with the API 5L standard, boasting both corrosion resistance and excellent fluid transportation performance.

Oil country tubular goods (OCTG) are mainly used for the drilling of oil and gas wells as well as the transportation of oil and gas. Oil casings are primarily used to support the wellbore during drilling and after well completion, so as to ensure the smooth progress of the drilling process and the normal operation of the entire oil well after completion. Oil casings are the lifeline for maintaining the operation of oil wells. Due to different geological conditions, the stress state downhole is complex, with tensile, compressive, bending, and torsional stresses acting on the pipe body comprehensively, which places high requirements on the quality of the casings themselves.
