Test Requirement

Show some usual test for reference,for different standard ,please see detail standard.

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.

After The User Agrees, 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.

Flaring Test:

According To The Requirements Of The Purchaser And Stated In The Contract, The Steel Pipe With Outer Diameter ≤76mm And Wall Thickness ≤8mm Can Be Done Flaring Test . The Experiment Was Performed At Room Temperature With A Taper Of 60 °. After The Flaring, The Flaring Rate Of The Outer Diameter Should Meet The Requirements Of The Following Table, And The Test Material Must Not Show Cracks Or Rips
