Performance and Technical Parameters

test

All steel pipes undergo non-destructive leak testing

Material and mechanical properties

The material types, mechanical properties, and requirements of stainless steel pipes are shown in the table below.

Welding applicability and welding performance:

E235 steel pipe, suitable for conventional welding

E235 non hexavalent chromium galvanized steel pipe, not recommended for welding applications

1.4571 stainless steel pipe, recommended to use arc welding

Recommended bending radius

When using manual or pipe bending machines to bend pipes, the bending radius must not exceed

Less than 3 times the outer diameter of the steel pipe.

temperature range

When using carbon steel seamless steel pipe (E235N) in the range of -40 ° C to+120 ° C, the pressure will not change significantly with temperature

Reduce the situation. Recommended maximum operating temperature+150 ° C

Parker stainless steel seamless steel pipe (1.4571) does not show a significant decrease in pressure with temperature changes when used in the range of -60 ° C to+20 ° C. The highest recommended operating temperature is+400 ° C.
