Seamless Precision Steel Tube

These tubes are manufactured according to DIN 73000. All aspects such as mechanical properties and dimension tolerances highly conform to the requirements of diesel engine tube.

In view of oil tube' s special quality requirements, we use high quality tube blank ST30Al, ST35, ST37, ST45, ST55 from Xingcheng steel or Bao steel which is better in mechanical properties regarding elongation rate, tensile strength, especially high pressure resistance.High pressure fuel tube Standard: DIN 2391 Specification: 6* 1.2 6* 1.5 6* 1.8 6* 2 etc.Surface: Bright and smoothAutomobile air-condition tube Process: Heat treatmentSurface: Bright and smoothMechanical properties: Flattened completely, bend at any angle without crack and break Substitute for copper or aluminum pipe
