Seamless (SMLS) steel pipes are primarily used in various industries due to their strength and durability. Here are some key applications based on their outer diameter (OD).

When selecting seamless steel pipes, several factors must be considered to ensure optimal performance and suitability for the intended application. The following principles can guide the selection process.

Here's an overview of the causes of surface defects of cold-drawn seamless steel pipes.

The manufacturing processes for LSAW (Longitudinal Submerged Arc Welding) steel pipes, including UOE and JCOE methods, are designed to ensure continuous advancement. This involves finalizing the tube formation, shaping, and positioning of the weld seam, enhancing pipe dimensions, welding quality, and production efficiency.

This article will briefly introduce thickness limit of heat treatment for carbon steel pipes.

The standard lengths of seamless pipes (SMLS pipes) are generally 6 meters (or 5.8 meters), 9 meters, and 12 meters. However, lengths can be customized according to customer requirements. This article will briefly introduce the standard length of seamless pipe.

The physical tolerances for LSAW (Longitudinal Submerged Arc Welding) steel pipes are critical to ensure the pipes meet the required specifications and performance standards. These tolerances typically cover dimensions such as outside diameter, wall thickness, length, and straightness.API 5L has a clear requirement on the physical tolerance for manufacturing LSAW Steel Pipes. Here are the standard tolerances for LSAW steel pipes.

Cold-drawn seamless steel pipe technology is crucial in the steel industry, playing a key role in manufacturing high-quality steel pipes. These pipes are known for their excellent mechanical properties and high-precision dimensions, making them widely applicable in petroleum, chemical industries, machinery, automobiles, and other fields. This article will briefly introduce technical requirements for cold drawn seamless steel pipes.

Proper storage of industrial spiral steel pipes is crucial to maintaining their quality and extending their service life. Here are some guidelines to ensure effective storage.

Poor quality SSAW (Spiral Submerged Arc Welded) steel pipes are prone to burrs due to the subpar equipment used by some inferior manufacturers. These burrs can scratch the pipe's surface and cause it to fold easily. Additionally, the pipes often have thin and weak seams, leading to a host of defects. This article will briefly introduce how to identify the quality of SSAW steel pipe.

Spiral Submerged Arc Welding (SSAW) steel pipes are manufactured using strip coil as raw material. These pipes are formed by extruding the material at normal temperatures and welded with an automatic double-wire double-sided submerged arc welding process. Here, we explore the classifications and applications of SSAW steel pipes.

This article will briefly introduce processing methods commonly used for seamless steel pipes.
