The seamless steel pipe for fluid (fluid pipe) is a kind of hollow section with no welds from beginning to end. Seamless steel pipes for fluids are divided into two categories: hot-rolled seamless steel pipes for conveying fluids and cold-drawn seamless steel pipes for conveying fluids.
Standard
The standard of seamless steel pipe for fluid transportation is GB/T 8163-1999. The outer diameter and wall thickness of seamless steel pipe for fluid transportation should meet the requirements of GB/T17395. The length requirements of seamless steel pipes for conveying fluids: hot-rolled pipes are generally 3 to 12 meters, and cold-drawn pipes are generally 3 to 10.5 meters. Both ends of seamless steel pipes for conveying fluids should be perpendicular to the axis of the steel pipe, and the cut burrs should be removed.

The main purpose
Pipes used to transport fluids. Pipes used to transport oil, natural gas, gas, water and certain solid materials.
FAQ
Question: What is the difference between seamless steel pipes for fluids and seamless steel pipes for structures?
Answer: Structural seamless steel pipes are suitable for seamless steel pipes for general structures and mechanical structures. Seamless steel pipes for fluids are suitable for general seamless steel pipes for fluid delivery. The main difference between it and the structural seamless steel pipe is that the fluid seamless steel pipe is subjected to hydraulic test or ultrasonic, eddy current, and magnetic flux leakage detection one by one. Therefore, in the standard selection of pressure pipeline steel pipes, structural seamless steel pipes should not be used.
