Jiangsu Liangyi is an ISO 9001-certified nickel-alloy forging manufacturer in China supplying Monel 400 / UNS N04400 / W.Nr. 2.4360 (NiCu30Fe / Alloy 400) open-die forgings and seamless rolled rings to oil & gas, marine, chemical, refinery and nuclear projects in India and worldwide, to ASTM B564 / ASME SB-564.
Why Monel 400 / 2.4360 for Indian oil & gas, marine and refinery projects
Monel 400 is a nickel-copper alloy (6370% Ni, 2834% Cu) with seawater corrosion < 0.025 mm/year and unmatched resistance to hydrofluoric acid the standard material for HF alkylation units in refineries, for coastal/offshore seawater service, and for caustic process equipment. For sour (HS) wellhead service it complies with NACE MR0175 / ISO 15156-3 at 35 HRC.
Documented deliveries
Oil & gas (USA): 48 Monel 400 wellhead valve bodies, 103 MPa, HS service, NACE MR0175, TUV 3.2 zero corrosion in 3 years, maintenance down 70% vs 316L.
Marine (Australia): 12 Monel 400 propeller shafts (OD 180 4,200 mm), ABS/DNV, measured 0.018 mm/year, no pitting after 4 years.
Chemical (Germany): 20 Monel 400 seamless rolled rings for a 70% HF reactor, 0.04 mm/year after 5 years.
