  • Seamless Steel Pipe

    Seamless pipe Including:Carbon Steel PipeSeamless Line PipeBoilers TubesStructural Steel PipePrecision Steel PipeAlloy Steel PipeNickel Alloy Pipe

    According to the production method, the seamless pipe is divided into a hot rolled pipe, a cold rolled pipe, a cold drawn pipe, an extruded pipe, a top pipe etc. 

    According to the shape of the section, the seamless steel pipe is divided into two types: a circular shape and an irregular shape, and the shaped pipe has a square shape, an elliptical shape and the like. 

    The maximum diameter is 650mm and the minimum diameter is 0.3mm. 

    Seamless steel pipe is mainly used as petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high-precision structural steel pipe for automobile, tractor and aviation.

Steel pipe internal stratification

The tube is generally believed that non-metallic inclusions in the steel tube will destroy the continuity and compactness, severe inclusions will lead to appear the steel pipe delamination phenomena. Another thought is hydrogen induced cracking, namely due to hydrogen accumulation caused by metal steel internal gas pressure is too high, the formation of white spots in the round tube, crack extension occurs in the rolling process, and ultimately form a layered defects. In addition, the stress exceeds the strength of two rolls of plastic rotary piercing uneven deformation can also cause delamination.

    Square pipes welding

    From welding square tube deformation theory shows that the impact of welding deformation square tube size is a major factor: the larger the size of weld, weld more metal, the greater the deformation; weld sizes are equal, the greater the weld heat input, resulting in deformation greater; welded square tube big long weld time, welding deformation segment is smaller than the straight; welds arranged asymmetric or symmetric, but asymmetric arrangement, although welded pipe, welds more serious deviation, the greater the deformation; The smaller component rigidity, the greater the deformation.

    Welding process of straight seam welded steel pipe

    The straight seam steel pipe adopts a small specification model, which can avoid crack and deformation. The welding current is 20% lower than that of high carbon steel. In order to ensure the ignition of electric arc, DC reverse connection is adopted. In multi-layer welding, the temperature shall be controlled. After welding, forced water cooling can be adopted without arc outside the groove. The wire joints shall be connected correctly, and the weld deformation can only be corrected by cold drawing.
