In the Oil, Gas & Petrochemical industry, the stakes are high: extreme temperatures, corrosive media, and intense pressure demand components that deliver zero-failure performance. At Cangxian Tiancheng Pipe Fittings Co., Ltd., we supply fully certified oil & gas pipe fittings and petrochemical pipe fittings designed for safe, efficient, and uninterrupted fluid transport — even in the harshest environments.
With advanced forging, heat treatment, and testing capabilities, we are a trusted supplier for pipeline infrastructure, refinery plants, chemical processing systems, and offshore applications worldwide.
Oil & gas pipelines operate under high risk and high performance conditions. Our wholesale pipe fittings coupling ensures that hazardous and volatile fluids including crude oil, LNG, LPG, and refinery by-products are transported securely, minimizing downtime and the risk of leaks.
Leak-proof connections in high-pressure systems
Engineered to withstand H₂S, CO₂ and abrasive contaminants
Precision tolerances for safe integration with pipelines and process piping
Compliant with API, ASME, ASTM, ISO standards
We deliver a full range of carbon steel, alloy steel, and stainless-steel fittings designed to perform in offshore drilling rigs, midstream transmission networks, and refinery operations.
Petrochemical processing exposes pipeline components to acids, solvents, and toxic chemicals. Our fittings are engineered with enhanced corrosion resistance, heat resistance and metal integrity to ensure long-term durability in continuous operations.
Compatible with abrasive and corrosive chemicals
Enhanced stress-corrosion cracking resistance
Superior performance in high-temperature cracking units and reactors
We manufacture customized pipe fittings tailored to critical petrochemical facilities such as ethylene crackers, ammonia plants, and polymer production.|
