Material & Manufacturing Process

Premium Carbon Steel Forged Pipe Fittings | Heavy-Duty Socket Weld & Threaded High-Pressure Components.

Manufactured in full compliance with ASME B16.11, BS 3799, and MSS SP-83 standards, our carbon steel forged pipe fittings deliver superior pressure integrity and thermal shock resistance. Utilizing closed-die forging, precision CNC machining, and heavy hydraulic presses up to 6,800 tons, we process premium certified carbon steel grades. This includes ASTM A105, A350 LF2 Class 1/2 for low-temperature environments, and high-yield line steel. Fully compliant with NACE MR0175/ISO 15156 for sour service, all socket weld and threaded fittings undergo normalized heat treatment, ultra-precise thread chasing (NPT/BSP), and mandatory 100% NDT inspection (UT, MT, PT) to guarantee zero-defect internal soundness.

Specification Range

Jiangyin Gaoxin Pipe Fittings Co., Ltd. manufactures a wide portfolio of carbon steel forged elbows, tees, couplings, unions, caps, nipples, and olets (Weldolets, Threadolets, Sockolets). Driven by heavy hydraulic forging presses with capacities reaching up to 6,800 tons, our facility fabricates high-strength components across a versatile size spectrum. Dimensional coverage spans small-bore precision lines (DN6 / 1/8") up to heavy-duty forged connections (DN100 / 4"). Pressure ratings cover Class 3000, Class 6000, and Class 9000, featuring exact Socket Weld (SW), NPT, BSPT, and BSPP threaded profiles to satisfy stringent engineering specifications.

Product Advantages

Operating since 1993 under an ISO 9001 certified quality management system, our company guarantees exceptional mechanical toughness, dense grain structure, and high fatigue endurance

  • International Certification: Our forged carbon steel fittings hold recognized global credentials, including PED 2014/68/EU, AD2000, EAC, NORSOK M-650, and marine classification approvals from DNV, ABS, and BV. Specialized black phosphatizing, anti-rust oil coating, and plastic end caps protect precise threads and socket bores during maritime transport
  • 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 packaging, our components optimize lifetime total cost of ownership.

Applications

Engineered for high-pressure fluid control, mechanical impulse resistance, and leak-free joint stability, our carbon steel forged fittings are essential in heavy industrial processing. They are extensively deployed in high-pressure hydraulic lines, boiler feed-water loops, steam headers, and onshore oil refineries. Furthermore, our NACE-compliant low-temperature carbon steel forged components serve in offshore drilling rigs, FPSO vessels, LNG processing plants, chemical synthesis reactors, and subsea manifold systems. Their dense forged grain structure, perfect thread alignment, and absolute pressure containment guarantee continuous, zero-leak operational safety across severe temperature and ultra-high pressure applications worldwide.
