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.

Maintenance requirements for LSAW steel pipe

LSAW steel pipe is a kind of welded steel pipe. Steel pipe parallel to the longitudinal direction of the steel pipe. The hot rolled steel coil is formed by forming machine, and then the said coil is converted into a cylinder and welded by using high frequency current skin effect and proximity effect or arc combustion under the flux layer, so that the edge of the pipe billet is heated, melted, fused and cooled to form under a certain extrusion pressure, correct, petroleum, metallurgy, construction, coal mine, port, machinery, and other industries are widely used in the transportation of oil and gas, low-pressure water and gas transportation, mine fluid transportation , belt conveyor, automobile drive shaft and other industries.

LSAW pipe inspection methods

There are many kinds of Q235B LSAW welded pipe quality inspection methods, among which the physical method is also the most commonly used inspection method, physical inspection is the use of some physical phenomena for determination or inspection methods. Material or Q235B LSAW welded pipe internal defects inspection, are generally used non-destructive flaw detection methods. The current nondestructive flaw detection has magnetic flaw detection, ultrasonic flaw detection, ray detection, penetration flaw detection, etc..
What factors will affect the quality of spiral steel pipe

How to control the quality of spiral steel pipe? The piercing temperature of steel billet varies depending on the raw material. The temperature of most hot expanded welded pipes is about 1200℃, and slightly lower when the carbon content and other alloying elements are higher.
