Process lines that handle hydrofluoric acid demand a material that does not compromise under aggressive media — purity, seam integrity and correct grade selection decide service life. This pure nickel pipe is offered in Ni200 (UNS N02200) and Ni201 (UNS N02201), grades long specified for hydrofluoric acid environments and general chemical service. Seamless construction removes the weld seam, and custom sizing lets the pipe match your line exactly rather than forcing the line to fit a stock size. With per-batch composition testing and EN 10204 3.1 documentation, the pipe arrives with the evidence behind its performance.
| Parameter | Value | Note |
|---|---|---|
| Product form | Seamless pure nickel pipe / tube (cold-worked) | no longitudinal weld seam |
| Size | Customized per drawing | OD / wall thickness / length |
| Temper | Annealed / cold-worked | per drawing |
| Surface finish | Pickled / bright | per drawing |
| Tolerances | Per ASTM B161 / GB/T 2882-2023 | exact values per drawing |
The 10 kg minimum order for custom pipes covers drawing setup and heat allocation, so tolerances can be locked per drawing.
Pure nickel is a long-established material for handling hydrofluoric acid, from anhydrous HF systems to aqueous acid service in chemical plants. Resistance in practice depends on acid concentration, temperature and aeration, so the grade and wall schedule are confirmed against the actual service conditions. Ni200 and Ni201 cover the industrial HF duty band; share your media conditions and we will confirm the grade and dimensions for the application.

MAWP estimated with the Barlow formula MAWP = 2·S·t/D for a reference pipe of 16 mm OD, assuming allowable stress S = 100 MPa. Size is customized per drawing; actual design values are confirmed per drawing and the governing standard.
| Wall thickness t | MAWP (16 mm OD, S = 100 MPa assumed) |
|---|---|
| 1.0 mm | 12.5 MPa |
| 1.5 mm | 18.75 MPa |
| 2.0 mm | 25.0 MPa |

Changzhou DLX Alloy Co., Ltd. has manufactured nickel alloys since 2002 in a 12,000 m² factory rated at 1,200 tonnes per year. Corrosion in media such as hydrofluoric acid is often decided by impurities, not by the nickel itself. That is why every DLX order starts with a grade-level impurity budget — carbon, iron, copper, sulfur — locked against the composition table, then held through melting, drawing and inspection with per-batch testing and EN 10204 3.1 documentation.
A: Pure nickel is an established material for HF environments. Practical resistance depends on acid concentration, temperature and aeration; provide your service conditions and we will confirm the grade and dimensions for the application.
