Standard length of welded steel pipe

Welded steel pipes, known for their high strength, corrosion resistance, and smooth surface, are made by welding various materials to meet diverse usage needs. These pipes are extensively used in construction, manufacturing, machining, and other industries. Common lengths for welded pipes are 6 meters and 12 meters, which cater to most usage requirements. During transportation and storage, welded pipes often need to be cut; thus, selecting different lengths based on specific needs is practical.

Standard length requirements for welded pipes are as follows:

Straight seam welded pipe (ERW Pipe/LSAW Pipe): Length≤12000mm

Spiral welded pipe (SSAW Pipe): Length≤16000mm

Straight Seam Welded Pipe Length Requirements:

Globally, welded steel pipes are categorized into short and long welded pipes based on their length. In national standards, they are divided into long welded pipes and specified length welded pipes. The specified length welded pipe refers to a straight seam welded pipe with a length of 12000mm or less.

According to the latest standards, the length of straight seam welded pipes should be:

Length≤12000mm

This standard ensures the ease of production and storage and helps maintain pipe quality. Length detection methods include laser scanning and manual measurement.

Spiral Welded Pipe Length Requirements:

Spiral welded pipes, widely used in petroleum, natural gas, chemical industries, and water supply, have specific length standards:

Length≤16000mm

Adhering to this standard facilitates production and storage while ensuring quality control. Advanced testing equipment, such as laser scanners or CNC production lines, is commonly used to measure spiral welded pipes.

Welded pipes are versatile with extensive market demand, varying in specifications and applications across different industries. When purchasing welded pipes, it is crucial to understand their specifications and intended uses to select the appropriate length for your needs.
