Thin Wall Thickness Big Outer Diameter Steel Round Pipe High Precision Welded Steel Tube
Description:
Our thin-walled, high-precision welded steel tubes feature large outer diameters, ideal for demanding industrinal applications. With a reduced wall thickness, these tubes offer increased flexibility and reduced weight without compromising strength. Manufactured from high-quality steel alloys, our tubes undergo rigorous testing to ensure exceptional accuracy, durablity, and resistance to corrosion and wear. Perfect for use in machinery components, hydraulic systems and other heavy-duty applications.
Material: E215, E255, C35E, C45E , E355, 26MnB5, 34MnB5, 50CrVA , SAE1026, SAE5160H, PA12, MT1010, 45# , GCr15,GCr9SiMn,PA12,100 Cr6 etc.
Diameter range:15-180mm
Thickness Range:1.7-25mm
Advantage:
Top class of welding line: SG/76 Enhanced High-precise High Frequency Welding Tube Production Line. The tube is of small outer diameter (D) and thick wall thickness (t): t/D≥0.2, and high size precision.
Wide range of dimension, high precision, and good quality of tube surface.
Deliver condition:
| +C | No heat treatment after the final cold drawing process. |
| +N | After the final cold drawing operation the tubes are normalized in a controlled atmosphere. |
Test:
TUltrasonic test,
Eddy Current Test.
Also we have our own lab to control the quility of material and products.
