Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying 12CrMo9-10 / W.Nr. 1.7375 (A182 F22) open-die forgings, seamless rolled rings, reactor nozzles and thick-wall fittings to refinery, hydrogen-plant and petrochemical projects in India and worldwide, to EN 10028-2 and ASTM A182 F22.

Why 12CrMo9-10 / 1.7375 for Indian refinery projects

12CrMo9-10 is the 2.25Cr-1Mo standard for high-temperature hydrogen service, sitting high on the API RP 941 Nelson curve for resistance to high-temperature hydrogen attack (HTHA) with elevated-temperature creep strength. For India's refining, petrochemical and hydrogen-plant sectors, 1.7375 suits hydrotreater/hydrocracker reactor nozzles and manways, reformer heater fittings, hydrogen-compressor valve blocks and thick-wall hydrogen-stream fittings.

Documented capability

Refinery/petrochemical: hydrotreater/hydrocracker reactor nozzles/manways, separator heads.

Hydrogen plant/compression: hydrogen-compressor valve blocks, thick-wall hydrogen fittings.

Reformer/heater: charge-heater fittings, flanges.

General: bars, discs, hubs, sleeves, custom forgings.
