Product Description

STKM11A Auto Exhaust System Welded Steel Pipe

Typical fields of application are in:
Automobile and motorcycle Shock Absorber Pipe
Hydraulic-cylinder Pipe
Mechanical steel pipes for auto and motor parts
Gas Spring pipe
motor Casing Pipe etc


size:length--2~12m WT--2~5mm OD--10-20mm


material:STKM11A


Production process: ordinary high-frequency welded pipe


Advantages: small diameter and thick wall


Surface Quality:The internal and external surfaces of the steel tube are not allowed to have cracks, scabs, folds, delaminations, laps, and burns. Allows for scribes, scratches, misalignment of welds, burns, oxide scales, and external burr removal traces that are not more than a negative wall thickness deviation


Inspection items:

chemical composition

Tensile test

Ultrasonic examination

Eddy current flaw detection

Bending test

Flattening test
