Our petroleum pipelines are manufactured from high-grade carbon and micro-alloyed steels, delivering exceptional yield strength and collapse resistance. Through precision wall thickness control and full-length quench & tempering treatment, the pipes achieve uniform mechanical properties with superior resistance to sulfide stress cracking (NACE MR0175 compliant). Our product range covers casing, tubing, and line pipes with various threading types and anti-corrosion coatings (FBE/3LPE). All products strictly comply with API 5CT/5L, ISO 11960 and customer-specific standards, ensuring reliability in drilling, extraction and transmission applications.

Our oil pipelines are produced using state-of-the-art JCOE forming technology and submerged arc welding (SAW) processes. The manufacturing process features automated ultrasonic testing systems, full-length X-ray inspection, and computer-controlled hydrostatic testing up to 30 MPa. Additionally, the production line includes in-line heat treatment for stress relief and precision end-facing equipment, ensuring strict dimensional tolerances (OD ±0.5%, WT ±5%) are consistently met.

In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
