Seamless Steel Pipe

Seamless pipe Including:Carbon Steel Pipe, Seamless Line Pipe, Boilers Tubes, Structural Steel Pipe, Precision Steel Pipe, Alloy Steel Pipe, Nickel 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.
Centerway Steel's Commitment to Sustainable Development and Environmental Excellence

“Firmly establish and practice the concept that green mountains are golden mountains, and plan for development at the height of the harmonious coexistence of man and nature.” Centerway Steel actively take action to “innovation” as a breakthrough, “quality” as the overall goal, and continue to promote carbon reduction, emission reduction, energy saving and other environmental protection and governance measures, writing the sky is more blue and the mountains are greener, high-quality and efficient development of the iron and steel answer sheet.
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.
