Opis produktu
Automatyczny układ wydechowy STKM11A SPARTED RURE
1. Petails:
| application |
Automobile and motorcycle Shock Absorber Pipe Hydraulic-cylinder Pipe Mechanical steel pipes for auto and motor parts Gas Spring pipe motor casing pipe |
| 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 |
