Import Din2391 High Precision Carbon Steel Pipe — Buy in Bulk from Supplier in China

The DIN2391 high precision carbon steel pipe is manufactured to meet strict dimensional and surface quality standards for applications requiring minimal deformation under stress. It is produced from low-carbon steel with controlled carbon content, suitable for cold drawing and precision machining. The pipe is supplied with a bright, oxide-free inner and outer surface, ensuring compatibility with hydraulic and pneumatic systems without additional cleaning.

This product is designed to withstand high-pressure environments without deformation after cold bending, flaring, or flattening tests. The mechanical properties align with DIN 2391-2, which specifies tight tolerances for outer diameter and wall thickness. Typical applications include fuel injection lines, hydraulic actuators, and instrumentation tubing where dimensional stability and surface finish are critical. The material is not alloyed, making it cost-effective for high-volume industrial use.

Buyers in the automotive, automation, and precision engineering sectors commonly source this pipe for components requiring consistent wall thickness and smooth internal bore. Packaging options include bundle wrapping, heavy tri-wall boxes, waterproof paper, and steel strip reinforcement. The supplier offers plain or varnished ends upon request. MOQ and lead time are not specified and must be confirmed directly with the factory. Shipping terms are typically FOB from Shanghai or Ningbo ports.
