Own Production Capacity Of The Entire Industry Chain

13 spiral steel pipe production lines+4 anti-corrosion and insulation lines, with an annual production capacity of 400000 tons, refusing intermediaries to profit from price differences

International authoritative certification escorts

Holding API 5L-0640 logo usage authorization (covering PSL1/PSL2, up to X80), strictly implementing ISO9001 system.

One stop turnkey service

Provide a complete set of customized services from bare pipes to 3LPE/FBE/epoxy coatings, and then to pipe end groove processing, reducing the hassle of outsourcing processing.CNAS Non destructive Testing and Full Inspection System - Turning Hidden Projects into "Transparent Projects"
Reject the "invisible killer" of welding seams and implement quality control in every steel pipe.

• Ultrasonic flaw detection:Perform 100% ultrasonic double inspection on the welds to ensure that the pipeline welds are tight and sturdy

• X-ray detection: Perform 100% X-ray on the weld seam to ensure that the pressure bearing capacity of the spiral weld seam is consistent with that of the base metal

• Hydrostatic test: Hydrostatic pressure test to ensure the safety of long-distance transportation pipelines (such as oil and gas, water sources).

• Other performance tests: Cnas testing also includes mechanical performance testing and chemical composition testing to ensure that pipeline performance meets customer standards for application.
