Hastelloy Pipe and Tubing
Hastelloy pipe & tube - mill-direct, ASTM B622, cut-to-length, global export.
Our Hastelloy pipe and tubing are produced mill-direct - Hastelloy C-276, C-22, B-2 and B-3 - as seamless and welded pipe and tubing for corrosive, high-temperature and strength-critical service.
Hastelloy is built for the harshest chemical environments. The C-series (C-276, C-22) resist oxidising and reducing acids, chlorides and pitting or crevice corrosion; the B-series (B-2, B-3) are nickel-molybdenum alloys specialised for pure reducing acids such as hydrochloric and sulphuric. All keep useful strength across a broad temperature range.
We produce Hastelloy pipe and tubing from about 6 mm up to 610 mm outside diameter, wall thickness 0.5-40 mm, in the annealed, with plain or bevelled ends; seamless and welded both supplied, with plain or bevelled ends and tolerances to specification. Seamless and welded both available from mill stock or made to order, each lot with EN 10204 3.1 mill test certificate and inspection on request.

Applications
Hastelloy pipe and tubing move fluids and gases where corrosion, pressure or temperature defeat ordinary alloys:
Chemical & petrochemical
reactors, columns and heat exchangers in aggressive acid service (C-276, C-22).
Flue-gas desulphurisation (FGD)
scrubbers, ducts and dampers (C-22, C-276).
Pharmaceutical & fine chemicals
high-purity process equipment (C-276).
Acid pickling & recovery
hydrochloric and sulphuric acid handling (B-2, B-3).
Pulp & paper / waste treatment
bleaches and corrosive-waste systems (C-276).
Frequently Asked Questions
What outside diameter range can you supply for Hastelloy pipe and tubing?
Pipe and tubing from from about 6 mm up to 610 mm outside diameter, wall thickness 0.5-40 mm; both stock and custom sizes are available, cut to length.
What is the minimum order quantity?
Stock sizes from one piece; mill lengths or heavy plate are priced per project. Tell us the grade, size and quantity for a quote.
Do you provide MTC / EN 10204 3.1?
Yes - every lot ships with EN 10204 3.1 mill test certificate, and third-party inspection can be arranged.
What is the typical lead time?
Stock items ship within days; made-to-order material is typically a few weeks depending on size, condition and certification.
Can you supply non-standard sizes or conditions?
Yes - custom sizes, non-standard walls or special tempers are available on request; we also offer cutting and surface preparation.
How do I choose between C-276, C-22 and the B-series?
The C-series (C-276, C-22) cover oxidising and reducing acids, chlorides and pitting; C-22 has broader oxidising-acid resistance. The B-series (B-2, B-3) are for pure reducing acids such as hydrochloric and sulphuric. Match the grade to your dominant corrodent.
