Product Description

Carbon Steel Seamless Pipes

Seamless carbon steel pipes are a type of steel pipe manufactured through hot rolling, cold rolling, or cold drawing processes after piercing steel ingots or solid tube blanks. The production process includes billet heating, pressure piercing, rolling and extrusion, sizing and cooling, and flaw detection and quality inspection. The main raw material is round tube blanks, and equipment such as conical roller piercing mills is used. Processing is divided into two categories based on the manufacturing process: hot rolling and cold rolling. Hot-rolled pipes commonly have an outer diameter greater than 32mm and are used for general structures, boilers, and oil pipelines. Cold-rolled pipes have higher precision, with an outer diameter down to 5mm, and are suitable for precision mechanical parts. Materials include high-quality carbon steel (such as No. 10 and No. 20 steel), low-alloy steel, and alloy steel. Based on applications, they are further subdivided into categories such as structural steel, fluid transportation, low and medium pressure boilers, high pressure boilers, petroleum cracking, and geological drilling.

Welded pipes

Welded pipes are divided into straight seam welded pipes and spiral welded pipes.

Straight seam welded pipes: Simple production process, high production efficiency, low cost, and rapid development.

Spiral welded pipes: Generally higher strength than straight seam welded pipes, they can be produced from narrower blanks to create larger diameter pipes, and can also be produced from blanks of the same width to create pipes of different diameters. However, compared to straight seam pipes of the same length, the weld length increases by 30-100%, and the production speed is lower. Therefore, smaller diameter welded pipes mostly use straight seam welding, while larger diameter welded pipes mostly use spiral welding.

Spiral welded steel pipes are further divided into two types: automatically submerged arc welded steel pipes and high-frequency welded steel pipes.
