Test Requirement

Hydraustatic Test:

The Steel Pipe Should Be Tested Hydraulically One By One. The Maximum Test Pressure Is 20 MPa. Under The Test Pressure, The Stabilization Time Should Be Not Less Than 10 S, And The Steel Pipe Should Not Leak. Or The Hydraulic Test Can Be Replaced By Eddy Current Testing Or Magnetic Flux Leakage Testing.

Nondestructive Test：

Pipes That Require More Inspection Should Be Ultrasonically Inspected One By One. After The Negotiation Requires The Consent Of The Party And Is Specified In The Contract, Other Non-Destructive Testing Can Be Added.

Flattening Test：

Tubes With An Outer Diameter Greater Than 22 Mm Shall Be Subjected To A Flattening Test. No Visible Delamination, White Spots, Or Impurities Should Occur During The Entire Experiment.

Hardness Test:

For Pipe Of Grades P91, P92, P122, And P911, Brinell, Vickers, Or Rockwell Hardness Tests Shall Be Made On A Specimen From Each Lot
