Difference between structural and fluid transportation steel pipe

Threewaysteel pipe company can provide structural and fluid transportation steel pipe at the same time, and the range covers from SSAW steel pipe JIS A5525 to SSAW steel pipe EN 10217 / 10219 S235 as well as LSAW steel pipe. However, what’s the difference between structural and fluid transportation steel pipe?

1: Difference on specification. The eddy current experiment must be performed on fluid steel pipe once we use them for the transport of fluids.

2: Different use of scale. One is structural support, and another is transporting fluids (such as oil, water).

3. Specific examples: The 8163 steel pipe would have higher requirement than 8162. As 8162 can be substituted, but not vice verse GB/T8162-1999 (structural seamless steel pipe). It is mainly used for general structure and mechanical structure. It represents raw materials (trademarks): carbon steel 20, 45 steel; alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo and so on.
