Material & Manufacturing Process

Precision Butt Weld Reducing Tees | Heavy-Duty Seamless & Welded Branching Solutions.

Manufactured in full compliance with ASME B16.9 and EN 10253 standards, our butt weld reducing tees are engineered for precise 90-degree branch connections with reduced line sizes in high-pressure piping networks. 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 reducing 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. offers a comprehensive range of seamless and welded butt weld reducing tees tailored for variable-diameter piping manifolds. Backed by heavy hydraulic presses with capacities reaching up to 6,800 tons, our facility fabricates high-strength components 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 geometry, run-to-branch offset, and end-bevel profile to guarantee precise site butt-welding.

Applications

Engineered to regulate flow rates and pressure during line size reductions, our butt weld reducing tees are critical components across global processing facilities. They are extensively deployed in offshore oil and gas platforms, FPSO vessels, subsea manifold systems, and auxiliary bypass lines. Furthermore, our NACE-compliant carbon, stainless steel, and special alloy reducing tees serve in onshore petrochemical refineries, LNG liquefaction processing plants, chemical synthesis facilities, thermal and nuclear power generation plants, and long-distance energy transmission pipelines. Their superior structural strength and pressure containment guarantee continuous, zero-leak operational safety across severe temperature, pressure, and corrosive application environments worldwide.
