ERW Pipe
High Nickel Alloy ERW Pipes resist corrosion, hold their dimensional stability and carry heavier loads than conventional steel pipe. These are manufactured from superior-grade alloys, so they perform under extreme temperature and pressure. Petrochemical processing, pharmaceutical production and seawater cooling systems draw on exactly those properties. Both arc and gas welding methods work cleanly on this pipe. Inox Pumps is a leading manufacturer and supplier of High Nickel Alloy ERW pipes. We have been providing the best-quality piping solutions since 1999.
Sizes and lengths cover a wide range, which makes installation into an existing system straightforward. Every pipe we produce passes through strict quality control before it leaves the floor, so performance stays consistent from one batch to the next. Our engineers can advise on the right alloy for your application, and we cut to length on request. Choose High Nickel Alloy ERW Pipes where conditions turn severe and ordinary material won't last. Tell us the requirement and our team will work out the size, length and alloy that fits.

Applications Of High Nickel Alloy ERW Pipes
Oil and gas operators specify High Nickel Alloy ERW Pipes for sour gas handling, wellhead connections and offshore subsea lines. Hydrogen sulphide and chloride exposure destroy carbon steel within a single service cycle. Nickel Alloy ERW Pipes carry intense sulphuric acid, phosphoric acid and caustic solutions with no liner degradation and no replacement expense. Desalination plants running brine above 80°C use High Nickel Alloy Pipes & Tubes on high-pressure reverse osmosis feed lines and in evaporator tube bundles. Power generation cooling circuits, pharmaceutical bioreactors and marine seawater intake systems run the same pipe, because oxidation resistance and thermal stability above 600°C decide equipment uptime.
Features & Benefits of High Nickel Alloy ERW Pipes
- Corrosion Resistance: A stable passive film forms across the nickel alloy surface and holds in chloride-rich, acidic and caustic media. 316L stainless fails in the same service within months.
- High-Temperature Performance: Grades such as Inconel 600 and Hastelloy C276 keep their structural integrity at sustained temperatures above 600°C.
- Dimensional Consistency: ERW manufacturing holds OD and wall thickness inside ASTM B775 tolerance limits across full production runs.
- Weldability: All four grades weld cleanly with matched nickel alloy filler metals. No post-weld cracking, no sensitisation.
- Long Service Life: A correctly specified nickel alloy ERW pipe runs past 20 years in chemical plant applications without any surface coating.
- Low Maintenance: The passive corrosion layer regenerates itself, which takes periodic chemical passivation off the maintenance schedule.
Chemical Composition of High Nickel Alloy ERW Pipes
Chromium builds oxidation resistance; molybdenum extends performance in reducing acid environments; copper adds protection in sulfuric and marine media. Each grade targets a specific corrosion challenge. The composition table below covers the four grades most frequently supplied.
| Grade | Ni (%) | Cr (%) | Mo (%) | Cu (%) | Fe (%) | Other |
| Nickel 200 | 99.0 min | — | — | 0.25 max | 0.40 max | Mn 0.35 max |
| Monel 400 | 63.0 min | — | — | 28.0–34.0 | 2.5 max | Mn 2.0 max |
| Inconel 600 | 72.0 min | 14.0–17.0 | — | 0.50 max | 6.0–10.0 | C 0.15 max |
| Hastelloy C276 | Balance | 14.5–16.5 | 15.0–17.0 | — | 4.0–7.0 | W 3.0–4.5 |
Mechanical Properties of High Nickel Alloy ERW Pipes
Pipe wall integrity under combined internal pressure and thermal load depends directly on tensile and yield values. Hastelloy C276 delivers the highest tensile performance in the group at 690 MPa minimum; Nickel 200 serves applications where corrosion resistance outweighs load-bearing demands.
| Grade | Tensile Strength | Yield Strength | Elongation | Hardness |
| Nickel 200 | 380–550 MPa | 100–240 MPa | 30–40% | 70–130 HB |
| Monel 400 | 480–540 MPa | 170–310 MPa | 35–40% | 120–150 HB |
| Inconel 600 | 550 MPa min | 240 MPa min | 30% min | 120 HB max |
| Hastelloy C276 | 690 MPa min | 280 MPa min | 40% min | 100 HRB max |
Why Choose Our High Nickel Alloy ERW Pipes?
We manufacture and stock High Nickel Alloy ERW Pipes to ASTM B775, ASME SB775 and applicable DIN specifications in Nickel 200, Monel 400, Inconel 600 and Hastelloy C276. Raw material comes from certified mill sources with full heat-level chemical and mechanical traceability. Custom OD, wall thickness and cut lengths carry a 2 to 4 week lead time on non-stocked sizes. Third party inspection through TPIA agencies supports export orders. Send us your OD, wall, metal grade and quantity, and we'll confirm stock and lead time with the quote.

FAQs
Oil and gas, petrochemical, chemical processing, pharmaceutical, marine, desalination and power generation are the primary sectors. Any process line carrying chloride-rich media, concentrated acids or gases above 400°C is a strong candidate.
Yes. All four grades resist chloride pitting, crevice corrosion and oxidation. Hastelloy C276 takes both hydrochloric and sulphuric acid service, where austenitic stainless grades fail inside the first year of operation.
Nickel 200, Monel 400, Inconel 600 and Hastelloy C276 stay in stock with us. Inconel 625 and Alloy 20 come on a 4 to 6 week lead time.
ERW pipe forms from strip stock welded along a longitudinal seam, while seamless pipe extrudes from a solid billet. ERW gives tighter dimensional tolerances and suits lower-pressure service. Seamless handles higher pressure classes and carries no weld-line risk.
Yes. Custom OD runs from 6 mm to 168 mm, wall schedules from SCH 5 to SCH 80, and lengths up to 12 metres. Send your full specification and we will confirm feasibility and lead time.
