Amigo Impex is a nickel alloy pipe fittings manufacturer, stockist and exporter established in Mumbai, India, in 2013. Wrought fittings are certified to ASTM B366 / ASME SB-366, with buttweld dimensions held to ASME B16.9, which now carries the short radius elbow and return dimensions formerly published as ASME B16.28, and to MSS SP-43 for light-wall pieces. Two commercially pure grades make up the supplied range: Nickel 200 (UNS N02200) and Nickel 201 (UNS N02201). Carbon content sets the two apart. Nickel 200 permits 0.15% maximum and covers service at or below 315 °C; Nickel 201 caps carbon at 0.02% and takes the lines running hotter. Both grades hold 99.0% minimum nickel plus cobalt, a purity suited to caustic soda, chlor-alkali, fluorine and food processing circuits.
Seamless elbows, tees, reducers, caps and stub ends span 1/2 inch to 10 inch NB; welded and fabricated construction extends the bore to 48 inch NB. Forged fittings follow ASME B16.11: socket weld in Class 3000 from 1/4 inch to 3 inch, Class 6000 from 1/4 inch to 2 inch and Class 9000 from 1/2 inch to 2 inch; threaded in Class 2000, 3000 and 6000 from 1/4 inch to 3 inch. Twelve buttweld configurations draw on roughly 60 to 70 tonnes of alloy stock held in Mumbai. Own-works processing covers cutting, machining, threading, fabrication, testing and packing. Dispatch reaches pan-India; exports serve the USA, the Gulf, Europe and Asia, and OEMs in pumps, valves and process plants place most orders. Each consignment leaves with an EN 10204 3.1 mill test certificate, and our company holds AS 9120B, PED, ISO 9001:2015 and ISO 45001:2018 certificates.
Grade, nominal bore, schedule, end preparation and certification together decide whether a nickel pipe fitting matches a line class, so the parameters below fix the supply envelope confirmed against every enquiry.
Two separate document families cover ASTM B366 nickel fittings: a material specification fixing chemistry, testing and marking, and dimensional standards controlling centre-to-end measurement, wall tolerance and bevel geometry.
| Standard | Scope |
|---|---|
| ASTM B366 / ASME SB-366 | Factory-made wrought nickel and nickel alloy welding fittings |
| ASME B16.9 | Buttweld fitting dimensions and tolerances, NPS 1/2 to NPS 48, including short radius elbows and returns |
| MSS SP-43 | Light-wall Sch 5S and 10S corrosion-resistant fittings |
| ASME B16.11 | Forged socket weld and threaded fitting dimensions |
Alloy 200 and Alloy 201, the trade names met on most enquiries, are the two nickel buttweld fittings grades supplied under ASTM B366. Selection rests on one figure: the sustained metal temperature of the line.
Nickel 200 pipe fittings anchor the stocked range, serving caustic concentration plants, chlor-alkali cells and food processing lines with metal temperatures at or below 315 °C.
Nickel 201 pipe fittings withstand extremely heated conditions. Above 315 °C, the 0.02% carbon ceiling stops graphitisation from embrittling the fitting wall over long service.
Construction route sets the bore ceiling on nickel pipe fittings sizes. Seamless production stops at 10-inch NB; welded work carries on to 48 inches, and a geometry that isn't tabled gets produced to drawing.
| Fitting Group | Size Range | Wall or Class |
|---|---|---|
| Seamless buttweld fittings | 1/2 inch to 10 inch NB | Sch 5 to Sch XXS |
| Welded and fabricated butt-weld fittings | 1/2 inch to 48 inch NB | Sch 5S and 10S to NPS 30 (ASME B36.19M); Sch 40, Sch 80, Sch 160 and Sch XXS in the sizes for which those walls are tabulated in ASME B36.10M; 20 SWG to 10 SWG |
| Forged socket weld fittings | Class 3000: 1/4 inch to 3 inch; Class 6000: 1/4 inch to 2 inch; Class 9000: 1/2 inch to 2 inch | 3000 lb, 6000 lb, 9000 lb |
| Forged threaded fittings | 1/4 inch to 3 inch | 2000 lb, 3000 lb, 6000 lb |
| Special bores and custom geometry | Made to order | To drawing |
The nickel alloy fittings list below runs to twelve configurations, from elbows through tees and reducers to caps, stub ends and crosses, each bevelled and heat-marked.
One packing method never suits the whole range of nickel pipe fittings. Forged small-bore items travel in boxes, bevelled butt-weld pieces sit in timber cases with edge battens, and every unit carries a tag recording grade, size, schedule and heat number. Domestic orders move pan-India from the Mumbai facility, and export consignments ship from Mumbai to the USA, the Gulf, Europe and Asia. Ready material clears in 1 to 2 days, while made-to-order production takes around 30 days.
Every batch of nickel alloy fittings is verified before packing. Nickel 200 and Nickel 201 share the same 99.0% minimum nickel plus cobalt content and differ only in carbon, so handheld XRF cannot separate them. Carbon is confirmed by optical emission spectrometry or combustion analysis, supported by heat-number traceability back to the mill certificate. Dimensional checks run against ASME B16.9 or B16.11, with a visual pass over the weld bevel on butt-weld items and over the socket bore or thread form on forged items. Every order carries an EN 10204 3.1 mill test certificate, with 3.2 certification and third-party inspection arranged when the purchase order names them, and we at Amigo Impex hold certifications like AS 9120B, PED, ISO 9001:2015 and ISO 45001:2018.

ASTM B366, issued by ASME as SB-366, covers wrought nickel pipe fittings of seamless and welded construction. Dimensions follow ASME B16.9 for butt-weld fittings, MSS SP-43 for light-wall pieces and ASME B16.11 for forged types.
Carbon content is the difference: Nickel 200 pipe fittings permit 0.15% maximum, Nickel 201 only 0.02%. Order Nickel 201 for sustained service above 315 °C; at or below that threshold, Nickel 200 is the standard selection.
No. Nickel pipe fittings are supplied to ASTM B366 in commercially pure grades holding 99.0% minimum nickel plus cobalt. Copper nickel fittings are copper-base 90/10 or 70/30 alloys supplied under separate specifications, so the two products don't interchange.
Seamless nickel pipe fittings run 1/2 inch to 10 inch NB, welded and fabricated construction reaches 48 inches, and forged socket weld and threaded fittings cover 1/4 inch to 3 inches.
Roughly 60 to 70 tonnes of material stands in the Mumbai facility, and stocked nickel pipe fittings clear within 1 to 2 days. Fabricated large bores and non-standard geometry need roughly 30 days.
An EN 10204 3.1 mill test certificate ships with every nickel pipe fittings order, recording chemistry, mechanical results and heat number. A 3.2 certificate witnessed through third-party inspection follows on request.
Both constructions are standard for nickel fittings: seamless up to 10-inch NB, welded and fabricated beyond that to 48 inches. The mill test certificate states the route supplied on each order line.
