Material & Manufacturing Process

Premium Butt Weld Pipe Elbows | Heavy-Duty Seamless & Welded Directional Piping Solutions.

Manufactured in full compliance with ASME B16.9 and EN 10253 standards, our butt weld pipe elbows (including 45°, 90°, and 180° configurations) provide smooth directional flow changes with minimal pressure loss. Utilizing advanced hot-mandrel push forming, precision cold shaping, 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 elbow undergoes controlled heat treatment, exact end-beveling, and mandatory 100% NDT inspection (UT, RT, MT, PT) to guarantee flawless structural integrity.

Specification Range

Jiangyin Gaoxin Pipe Fittings Co., Ltd. provides a complete inventory of long-radius (LR), short-radius (SR), and custom-radius butt weld elbows for complex piping systems. Driven by heavy hydraulic presses with capacities reaching up to 6,800 tons, our factory manufactures seamless and welded elbows 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 thicknesses range from light-wall Schedule 10/40/80 up to XXS and custom heavy-wall specifications up to 100mm. Every dimension is strictly verified via coordinate measurement systems to guarantee precise end-bevel 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, tight dimensional tolerances, and high fatigue resistance

  • Optimized Flow Performance: Our butt weld elbows carry recognized global credentials, including PED 2014/68/EU, AD2000, EAC, NORSOK M-650, and marine classification approvals from DNV, ABS, and BV. Optimized interior curvature minimizes fluid turbulence and erosion, extending component service life under severe operational flow velocities
  • 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 elbows protect client infrastructure while lowering lifetime total cost of ownership.

Applications

Designed to safely redirect fluid flow across high-pressure and extreme-temperature environments, our butt weld elbows are critical components across global process industries. They are extensively deployed in offshore oil and gas production platforms, FPSO vessels, subsea manifolds, and marine piping loops. Furthermore, our NACE-compliant carbon, stainless steel, and special alloy elbows serve in onshore petrochemical refineries, LNG liquefaction processing terminals, chemical synthesis plants, thermal and nuclear power plants, and long-distance energy transmission pipelines. Their robust structural strength and pressure integrity guarantee continuous, zero-leak operational safety across severe temperature, pressure, and corrosive application environments worldwide.
