A 12Cr2Mo pipe，When D<30 mm and SW3 mm，the lower yield strength or specified plastic extension strength can be reduced by 10 MPa.

Test Requirement

In addition to ensuring the chemical composition and mechanical properties, the steel pipe directly rolled by ingot shall be subject to low power inspection, and eddy current inspection or magnetic flux leakage inspection can be used instead of hydraulic test.

Supply Ability

2000 Tons Per Month Per Grade of  Seamless steel tubes for high-pressure chemical fertilizer processing equipments.

Packaging

In Bundles And In Strong Wooden Box

Delivery

7-14 days if in stock, 30-45 days to produce

Payment

30% depsoit, 70% L/C or B/L copy   or  100% L/C at sight
