When designing complex piping systems that require precise 45-degree branch connections, the ASME B16.9 Lateral Tee stands out as a critical component. At Xi'An QinSteel Trading Co., Ltd, we specialize in manufacturing these tees with strict adherence to ASME standards, ensuring leak-proof performance and seamless integration into high-pressure oil, gas, and chemical pipelines. Our global clients trust us for our rapid delivery, certified quality, and ability to tailor solutions for unique project needs.
The product is engineered to divert flow at a 45-degree angle, minimizing turbulence and pressure loss in pipelines. Available in sizes from ½" to 48", these tees are constructed from materials like carbon steel (A234 WPB), stainless steel (WP304/316), and duplex alloys (UNS 31803), making them ideal for corrosive or high-temperature environments. With butt-welded ends for secure connections and compliance with ASME B16.9 dimensional tolerances, they ensure reliability in critical applications.

All materials undergo rigorous testing to ensure compliance with ASME and ASTM standards.
Machined to ±0.3mm tolerances using CNC technology, our ASME B16.9 Lateral Tees guarantee seamless fitment in pipelines.
Choose from materials validated for harsh conditions, including offshore oil rigs and chemical processing plants.
Pre-certified for API, PED, NACE, and GOST, reducing approval delays for your projects.
Tailor wall thickness, coatings (3PE/FBE), or branding with our OEM services.
Every product undergoes dimensional checks, hydrostatic testing, and non-destructive examination (NDE). Third-party inspectors validate compliance before shipment.
We use RFID-tracked wooden crates with shock-resistant padding to protect against transit damage. Real-time monitoring ensures your order arrives intact, even to remote sites.
