Product Series for Seamless Steel Tubes

We produce precision seamless steel pipes, honing pipes, and piston rods. You can also customize hydraulic cylinders. The surface of precision seamless hydraulic steel tubes can be galvanized and phosphated to prevent rusting. Standard: DIN2391/C, EN10305-1, EN10305-4, ASTMA519. We provide raw materials for various types of excavation machinery, lifting machinery, mining machinery, agricultural machinery, and industrial equipment manufacturers.

Seamless mechanical tubing is a solid steel billet that is heated and formed into a hollow tube without the use of seams or welds. Unlike welded pipes, seamless tubing are made through a perforation process to ensure the accuracy of OD and ID.

Quality Control for Seamless Steel Tubes

Our factory implements strict quality control throughout the entire process from raw material procurement to finished product delivery. All mechanical tube are produced in accordance with international standards and follow uniform tolerances. Our factory has a professional quality inspection team.

Check the outer diameter and wall thickness tolerance, surface roughness, inner wall cleanliness. And check whether there are scratches, bumps and other problems on the appearance. Check whether it has anti-corrosion and anti-rust capabilities. We are committed to ensuring that every seamless steel pipe can meet the high performance needs of customers.

Endoscopic Inspection

The endoscope mainly detects the inner wall smoothness and roughness of seamless hydraulic steel tube. whether there are surface defects, and whether there are impurities attached.

honed tube quality control

Polishing Inspection

Polishing is mainly to remove the oxide layer, welding residue or metal chips on the surface. Check whether the polishing effect of the inner and outer surfaces of the semi-finished customized hydraulic cylinder is uniform.

Dimensional Inspection

The inner diameter gauge detects the inner diameter of carbon steel pipes to ensure that it is consistent with the size required by customers.
