Hc-22 Nickel Based Alloy Extruded Seamless Pipe

Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. manufactures this pipe by hot extrusion: a single-pass process that converts a billet into a seamless hollow with ≥ 95 % material yield, uniform wall thickness, and no weld-seam risk. Standard rough pipe is OD 89 mm × WT 9 mm in lengths to 3 500 mm; finished pipe with pickling, cold rolling, and annealing is also available from the same production line, eliminating the need for a second supplier. Procurement teams source HC-22 nickel based alloy extruded seamless pipe from Ji lai da because every heat ships with an EN 10204 3.1 MTC, third-party inspection by SGS, BV, or TUV is available on request, and the mill operates under ISO 9001. The factory-direct model removes trading-company markups: the China manufacturer controls the full extrusion and processing chain, keeping material waste below 5 % and passing that saving into competitive pricing well below Western-mill equivalents for the same quality.

Seamless by Extrusion

Ji lai da manufactures HC-22 nickel based alloy extruded seamless pipe by hot extrusion — one pass from billet to seamless hollow with ≥ 95 % material yield. Extrusion produces more uniform wall thickness and smoother surfaces than pierce-and-roll or forge-and-drill, with no weld-related risks. Standard rough pipe: OD 89 mm × WT 9 mm, lengths to 3 500 mm. Finished pipe with pickling, cold rolling, and annealing is available from the same line — tighter tolerances without a second supplier.

Versatile Chemistry

The 22 % chromium forms a dense, self-repairing passive film in oxidizing conditions; 13 % molybdenum handles reducing acids, pitting, and crevice corrosion; tungsten adds resistance to localized attack in mixed environments. The PREN exceeds 45, and C-22 shows significantly lower corrosion rates than C276 in ASTM G28 Method B and ASTM G48 testing — a step-change when the service environment swings between oxidizing and reducing states, as it does in FGD scrubbers, waste incineration, and pharmaceutical batch reactors.

HC-22 Pipe — Buyer FAQ

Q1: When should I choose HC-22 over C276?

A: When your environment involves oxidizing acids — nitric, chromic, ferric chloride — or swings between oxidizing and reducing conditions. C276 is stronger in pure reducing-acid service; C-22 is the better all-rounder when both modes are present, such as FGD scrubbers and waste incineration plants.

Q2: What sizes do you supply?

A: Rough pipe: OD 89 mm, WT 9 mm, lengths up to 3,500 mm. Finished pipe: smaller processed dimensions with pickling, cold rolling, and annealing available. Custom sizes on request.

Q3: Why hot extrusion for HC-22?

A: One-pass forming, no weld seam, uniform wall, ≥95% yield. Pierce-and-roll can introduce ovality and surface defects; forge-and-drill wastes material. For a high-value alloy like C-22, extrusion saves raw material cost and reduces finishing work.

Q4: How is your pricing compared to other suppliers?

A: We have a real cost advantage. As a China manufacturer with our own extrusion line, we control the full production chain — no trading markups, no outsourcing fees. Our ≥95% material yield keeps raw material waste low, and that savings goes directly into competitive pricing. HC-22 nickel based alloy extruded seamless pipe from Ji lai da is typically priced well below Western-mill equivalents for the same quality.

Q5: Are you a manufacturer or trading company?

A: A China manufacturer. Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. operates our own hot extrusion and processing facilities. ISO 9001 certified with four additional industry certifications. Factory visits and third-party inspection welcome.
