Hangyang Compressor: an engineered machine, with a defined project boundary
杭州杭氧压缩机有限公司
Hangzhou Hangyang Compressor
The company was established in September 2000 and is based in the Qingshanhu area of Lin'an, Hangzhou. Its profile describes design, manufacture, sales and after-sales work for gas compressors.
Hangyang Group's 2025 annual report identifies this company as an associate. The compressor company's order scope should be established separately from the group's wider air-separation and industrial-gas projects.
The catalog covers oxygen, nitrogen, hydrogen, carbon dioxide, natural gas, feed gas and refrigerant duties. The two reviewed product routes below show how inlet state, pressure ratio and site utilities change the machine selection.
O₂ · selected manufacturer duty rows
Two oxygen duties, two different installation scales
The large unit starts from a much higher inlet pressure than the smaller selection. Compare the full inlet and outlet state, flow reference, power and cooling requirements; these are separate configurations, not a performance curve for one interchangeable machine.

N₂ · flow, pressure and utilities together
Nitrogen: compare 3 MPa and 9.5 MPa duties without losing the inlet basis
ZW-36/30 and ZW-11/95 are different configurations with different flow, stage count, power and installation needs.
Both selected rows use m³/h without N. Request volume reference conditions before comparing them with the oxygen entries or another nitrogen supplier.
Include nitrogen purity and impurities, source pressure during operation, inlet temperature and the receiving-system requirement. Obtain actual cooling-water supply/return conditions and electrical starting requirements.

Other published families
Labyrinth oxygen machines, large process frames and range-only gases
The labyrinth compressor table lists ZW-50/30 at 3,000 Nm³/h, 500 kW shaft power and 80 kN piston force, and ZW-100/30 at 6,000 Nm³/h, 980 kW and 160 kN. The table does not name the gas; the company's 2025 provincial product award names a 3,000–5,000 Nm³/h labyrinth oxygen compressor.
| Frame | Combined piston force | Gas force | Throws | Stroke options, inch | Max speed options, rpm |
|---|---|---|---|---|---|
| HYA | 130 kN | 160 kN | printed “2.4” | 10, 12 | 600, 500 |
| HYB | 270 kN | 320 kN | 1–6 | 11, 12 | 500, 428 |
| HYC | 470 kN | 560 kN | 1–10 | 14, 15 | 375, 333 |
| HYD | 800 kN | 980 kN | 1–10 | 14, 15, 16 | 375, 333 |
Hydrogen, natural gas, argon, booster nitrogen and skid-mounted families are published only as ranges: hydrogen 400–4,000 Nm³/h at 0.2–10 MPa; natural gas 150–6,000 Nm³/h at 0.2–16.5 MPa; argon 150–3,000 Nm³/h at 0.2–3.0 MPa; booster nitrogen 150–15,000 Nm³/h at 0.2–6.0 MPa; skid units 150–6,000 Nm³/h at 0.2–8.0 MPa. Each also gives a “piston rating” range without a unit, so it is not repeated here. A range is a family envelope; the quotation must state the selected machine's duty.
Registration and certificates. The certificates on the company site name the legal entity as HANGZHOU HANGYANG COMPRESSOR CO., LTD, unified social credit code 91330185720031147Y. Hangyang Turbine, a separate group company, lists the same street address, so use the name and code to identify the supplier. The site shows an ISO 50001 energy-management certificate, No. 03124En0034R0M, issued by Beijing Sanxing 9000 Certification for the design and manufacture of gas compressors and fittings, issued 18 December 2024 and valid to 17 December 2027 subject to annual surveillance, and a high-technology enterprise certificate GR202433005922 dated 6 December 2024. The ISO 9001, ISO 14001 and ISO 45001 certificate copies on the site show expiry dates in 2023 and 2024; ask for current copies. Checked against the manufacturer's site on 30 October 2026.
What the component design means for the project review
The manufacturer's component page provides useful engineering detail. Confirm which features and documents apply to the actual package.
Frame and drive end
Hangyang describes integral fine-grained cast-iron frames with reinforcing ribs, machined bearing seats and service covers, plus forged crankshafts and connecting rods.
Review: foundation/load drawings, lifting and maintenance space, coupling arrangement and access to replaceable bearing and guiding parts.
Rings, cylinders and packing
The source lists filled PTFE or other composites for piston rings/wear bands, gas-dependent cylinder materials and packing with optional lubrication, cooling and vent passages.
Review: actual gas-side lubrication, selected materials, leakage acceptance, replacement parts and operating-condition limits.
Distance pieces and gas separation
The description includes API D dual-chamber and long API B single-chamber distance-piece options, with venting or nitrogen purge according to the service.
Review: the supplied arrangement and safe routing/interface scope. Do not assume every model includes the same distance piece.
Water and lubrication systems
The company describes customer-specified API 618 circulating-water systems and factory-tested API 614 circulating-lubrication systems, including filters, pumps, coolers and instruments.
Review: supplied system boundaries, utility state, redundant pump/control scope and the offered unit's actual factory-test records.
Documented drafting role, with a limited scope
The national standards platform lists this company among the drafting organizations for JB/T 8694-2014, technical requirements for mesh valves of reciprocating piston oxygen compressors. The reviewed entry is current and concerns that component.
Its API 618 / API 614 descriptions are manufacturer statements. Define applicable editions, deviations, inspection and test scope on the order; neither a drafting role nor a catalog statement is a whole-machine certification.
Plan factory tests, transport and site reassembly together
The manufacturer describes complete-unit shipment where package dimensions permit. Larger units may be assembled and tested at the factory, then shipped in protected components for site reassembly. Define the split and responsibilities before finalizing the equipment price and delivery scope.
Issue one operating duty sheet
Gas analysis, min/normal/max inlet state, required flow and reference conditions, discharge pressure basis, hours and operating modes.
Agree package interfaces
Motor/supply, starting controls, cooling-water conditions, lube/water station scope, gas connections, vent/purge interfaces and piping/support responsibilities.
Approve drawings and acceptance
Current arrangement/foundation drawings, dimensional and weight splits, materials/cleanliness requirements, pressure-qualified performance and leakage tests, control/interlock checks and inspection records.
Define delivery and commissioning
Packing/preservation, lifting, qualified site reassembly/alignment, commissioning responsibilities, wear-parts identification and destination support terms.
Prepare a Hangyang process-gas enquiry
Choose oxygen or nitrogen, attach the process duty sheet and identify site utilities. A complete inlet state makes the proposed model and installation scope easier to compare.
Prepare the Hangyang duty enquiry →Questions before selecting a Hangyang gas compressor
Are all pressures in the tables gauge pressures?
No. Inlet pressure is labeled MPa(A), meaning absolute. The outlet column only says MPa, so the offer must specify its absolute/gauge basis.
Can the oxygen layout entry be used as a shipping size?
No. The large 2Z16 entry explicitly says two-level layout, 6,900 × 7,000 mm. Obtain current overall and shipment-split drawings, lifting weights and site-access requirements.
Does 45 t/h water mean water is included in the nitrogen package?
No. It is the source's total water figure for ZW-36/30. Agree the required supply/return conditions and whether water-station equipment, cooling infrastructure and piping are included.
Does group affiliation establish the compressor company's complete project capability?
The group annual report identifies the compressor company as an associate. Confirm the actual manufacturing/contracting entity and order-specific supply, tests and support scope.
