Description
Stpg370-E Welded Carbon Steel ERW Pipe
JIS G3454 STPG370 is a Japanese national standard for carbon steel pipes used in pressure piping. There are mainly two models, one is STPG370E and the other is STPG370S; The difference between the two models is that the thickness and weight of STPG370E steel pipe are greater than STPG370S steel pipe for the same model. Yuan Taide Run can produce STPG370E steel pipes, with customizable wall thickness, diameter, and length. Steel pipes have high dimensional accuracy, tight welds, good quality, and affordable prices. We welcome global buyers to inquire and place orders.

Notes
1. It is recommended that the minimum rate of growth is minimum.
2. It is necessary to preserve it
3. By the request, the tube of the diameter of 40A or less will perform the bending test instead of the pill test.
Dimensional Tolerance
The STPG370E steel pipe generally follows the following dimensional tolerance range in the standard. In practical applications, the dimensional tolerance of STPG370E steel pipe may vary.
