  • 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.

Introduction to the production measures of thick-walled spiral pipe

Spiral steel pipe is a low carbon carbon structural steel or low alloy structural steel steel strip rolled into a billet according to the angle of a certain spiral line (called the molding angle), and then made by welding the pipe seam, it can be made with a narrower strip to produce a large diameter steel pipe. Its specifications are expressed in terms of the outer diameter * wall thickness, welded pipe should ensure that the hydrostatic test, tensile strength of the weld and cold bending properties to comply with the provisions.

    Measurement of the length of straight seam steel pipe

    The basic principle is to install two fixed-length grating scales on the outside of the two ends of the straight seam steel pipe, the grating scales are driven by the rods near the ends of the steel pipe, and the length of the straight seam steel pipe is measured by the interference phenomenon of light. It is characterized by high accuracy. However, the scale is expensive and difficult to maintain, so it is sensitive to the effects of dust and site vibration.

    Introduction to the production process of spiral pipe

    Spiral steel pipe production process is simple, high production efficiency, into the material to produce a larger diameter welded pipe, but also with the same width of the billet to produce a different diameter welded pipe. However, compared with the same length of straight seam pipe, the length of welded seam increases by 30~100%, and the production speed is lower.
