Material & Manufacturing Process

High-Pressure Butt Weld Equal Tees | Heavy-Duty Seamless & Welded Branching Solutions.

Manufactured in full compliance with ASME B16.9 and EN 10253 standards, our butt weld equal tees are engineered for reliable 90-degree fluid division or combination in high-pressure piping systems. Utilizing advanced hot-extrusion, cold-hydraulic bulging, and heavy hydraulic forging techniques, we process a broad spectrum of certified materials. This includes carbon steel (ASTM A105, A234 WPB, A350 LF2), stainless steel (304/304L, 316/316L), duplex & super duplex alloys (S31803, S32750), and nickel-based alloys (Inconel 625, 254SMO). Fully compliant with NACE MR0175/ISO 15156 for sour service, each equal tee undergoes normalized heat treatment, precise CNC beveling, and mandatory 100% NDT inspection (UT, RT, MT, PT) to guarantee internal soundness.

Specification Range

Jiangyin Gaoxin Pipe Fittings Co., Ltd. supplies a wide inventory of seamless and welded butt weld equal tees for uniform-diameter piping manifolds. Backed by heavy hydraulic presses with capacities reaching up to 6,800 tons, our factory fabricates high-strength fittings across an expansive size range. Dimensional coverage extends from small-bore lines (DN15 / 1/2") up to extra-large outer diameter fabrications reaching DN3800 (150"). Wall thickness schedules span standard Schedule 10/40/80 up to extra-heavy XXS and custom heavy-wall specifications up to 100mm. Advanced coordinate measurement systems rigorously inspect every branch angle, center-to-end dimension, and end-bevel profile to guarantee precise alignment and effortless site butt-welding.

Product Advantages

Operating since 1993 under an ISO 9001 certified quality management system, our company guarantees exceptional pressure containment, structural rigidity, and high fatigue resistance

  • Superior Structural Integrity: Our equal tees hold prestigious global credentials, including PED 2014/68/EU, AD2000, EAC, NORSOK M-650, and marine classification approvals from DNV, ABS, and BV. Seamless forged branch crotch reinforcement mitigates stress concentration under thermal expansion and pressure fluctuations
  • Full Traceability & Documentation: Every shipment is delivered with an EN 10204 3.1 Mill Test Certificate featuring full 100% heat-number raw material traceability
  • Rigorous Testing & Inspection: Combined with sea-worthy protective export packaging, our components protect client infrastructure while optimizing lifetime total cost of ownership.

Applications

Engineered to handle equal-flow splitting or joining in severe operational environments, our butt weld equal tees are vital components across global energy and industrial facilities. They are widely deployed in offshore oil and gas production platforms, FPSO vessels, subsea manifold systems, and topside piping networks. Furthermore, our NACE-compliant carbon, stainless steel, and special alloy equal tees serve in onshore petrochemical refineries, LNG liquefaction processing terminals, chemical synthesis units, thermal and nuclear power plants, and main transmission pipelines. Their superior structural strength and pressure integrity guarantee continuous, zero-leak operational safety across severe temperature, pressure, and corrosive processing environments worldwide.
