Semi-finished nickel alloy seamless tube is a hot-extruded tubular blank supplied with controlled machining allowance on both outside diameter and wall thickness, allowing manufacturers to machine final dimensions, surface finishes, and tolerance requirements according to their own drawings.

When procurement engineers search for a qualified China manufacturer of Inconel 718 nickel based alloy pipe, Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. (Ji lai da) delivers factory-direct, fully traceable solutions engineered for the most demanding high-temperature and high-pressure environments. Unlike conventional 304 or 316 stainless steel pipes — which lose strength rapidly above 500 °C — Inconel 718 retains exceptional mechanical properties up to approximately 700 °C thanks to its unique precipitation-hardening metallurgy. As an integrated China manufacturer with in-house hot extrusion capability, Ji lai da ensures every Inconel 718 nickel based alloy pipe meets aerospace, oil & gas, and power generation specifications with full MTC documentation.

GH4169 seamless pipe, classified under GB/T 14992 and equivalent to Inconel 718 (UNS N07718 / W.Nr. 2.4668), is a precipitation-hardenable nickel-iron-chromium superalloy tube designed for extreme temperature and high-stress environments.

NS3304 seamless pipe is a high-performance nickel-based alloy tube manufactured according to GB/T 15007, equivalent to UNS N10276, W.Nr. 2.4819, and Hastelloy C-276. Produced through hot extrusion, the pipe features a fully seamless structure without longitudinal weld seams or heat-affected zones, providing consistent corrosion resistance and mechanical properties throughout the entire tube wall.

For buyers who find 316 stainless steel inadequate and Inconel 718 over-specified, Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. (Ji lai da) introduces the N08031 nickel based alloy seamless pipe — a super-austenitic, solid-solution alloy engineered for the most aggressive mixed-acid and halide environments. Where Inconel 718 excels through precipitation hardening for high-temperature strength, and C276 dominates in reducing-acid service, N08031 (Alloy 31) occupies a unique niche: its balanced 31% Ni / 27% Cr / 6.5% Mo / 1.2% Cu / 0.2% N composition delivers simultaneous resistance to oxidizing and reducing media that defeats both 316 and 904L — and in many sulfuric and phosphoric acid concentrations, even outperforms Inconel 625. As a direct China manufacturer with in-house hot extrusion, Ji lai da offers factory-direct N08031 nickel based alloy seamless pipe with full traceability and competitive pricing.

Hastelloy C276 nickel based alloy extruded seamless pipe is the flagship product of Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. (Ji lai da) — and for good reason. As the most widely specified nickel alloy in defense, chemical weapons demilitarization, and ultra-aggressive industrial service worldwide, C276 represents both the technical foundation and the commercial core of our business. Every Ji lai da C276 pipe is manufactured through hot extrusion at our own facility in China, achieving ≥ 95% material yield and < 5% loss, with bright internal and external surfaces straight from the extrusion press. Whether you are a defense procurement officer, an EPC contractor for chemical weapons destruction, or a mill-run quality buyer for petrochemical plant construction, Ji lai da delivers factory-direct Hastelloy C276 nickel based alloy extruded seamless pipe with full EN 10204 3.1 certification and FOB / CIF / DDP logistics. This is not a sideline product — this is what we do best.
