Production process of seamless steel pipe

Comparison of spiral steel pipe specifications

ERW stands for resistance welding. Resistance welding has the characteristics of high production efficiency, low cost, material saving, and easy automation. Therefore, it is widely used in aviation, aerospace, energy, electronics, automobiles, light industry and other industrial sectors. It is one of the important welding processes.

Los tubos de revestimiento para petróleo se consideran un producto de primera calidad en la industria de los tubos de acero, con una amplia variedad de especificaciones. Hay 15 tamaños de diámetro exterior diferentes, que van desde 114,3 mm hasta 508 mm. Los grados de acero se clasifican en 11 tipos, incluidos J55, K55, N80, L-80, P-110, C-90, C-95 y T-95. Hay varios tipos de conexión final disponibles para los tubos de revestimiento para petróleo, como STC, LC, BC y VAM. El proceso de producción e instalación de los tubos de revestimiento para petróleo implica una serie de pruebas rigurosas, que incluyen las siguientes.

Knowledge summary of seamless steel pipes for tubing materials

The tubing in the oil casing is a pipeline that transports crude oil and natural gas from the oil and gas layer to the surface after the drilling is completed.

Stainless steel welded pipe standard

Steel-plastic composite pipe, large-diameter coated steel pipe

Spiral steel pipe production process: It is a spiral seam steel pipe welded by automatic double-wire double-sided submerged arc welding with strip steel coils as raw materials, often extruded and formed.

Welded pipes are divided into spiral welded pipes and longitudinally welded steel pipes according to the forming process, and high-frequency resistance welding and submerged arc welding according to the welding process. Spiral welded pipes all adopt submerged arc welding process. For longitudinally welded pipes, submerged arc welded pipes are referred to as UOE, and longitudinal high-frequency resistance welding is referred to as ERW.

Spiral welded steel pipes refer to steel pipes with seams on the surface that are welded by steel strips or steel plates that are bent into round or square shapes.

Las tuberías de revestimiento de petróleo se utilizan para soportar las paredes de los pozos de petróleo y gas, asegurando el funcionamiento adecuado del pozo durante la perforación y después de su finalización. Hay dos tipos principales de tubos de acero que se utilizan para revestimientos de petróleo: revestimiento sin costura y revestimiento ERW. Aquí hay una comparación detallada entre ellos.

High-frequency welded pipes are generally completed through processes such as cold rolling, high-frequency welding, and forming. It is a kind of seamed tube.
