Introduction to ASTM A795 ERW steel pipe
ASTM A795 ERW (Electric Resistance Welded) Pipe is produced according to the standards set by the American Society for Testing and Materials (ASTM International). The ASTM A795 standard covers black and hot-dipped zinc-coated (galvanized) welded and seamless steel pipes specifically designed for fire protection use. "ERW" refers to the resistance welding process used to fuse the edges of the steel pipes together, forming a reliable and durable weld. Below is a comprehensive overview of ASTM A795 ERW pipes.

What is the standard length of seamless pipe and how to choose?
Seamless pipe, a type of steel pipe that is challenging to manufacture and shape, typically comes in standard lengths of 6 meters (or 5.8 meters), 9 meters, or 12 meters. These lengths are designed to meet production requirements and facilitate transportation. However, the appropriate length can also be customized based on market demand and specific customer needs. The length of a steel pipe is often related to its diameter: generally, the thicker the pipe, the longer it is. Small-diameter pipes are mostly below 6 meters, pipes with a diameter over 500mm are typically 10 to 12 meters, while others range from 6 to 10 meters. Below is a detailed introduction to the standard lengths of seamless pipes.
