SASPG Jianyang: process-gas and high-pressure air compressors
Match the MW, CNG or 2V application to its manufacturing entity, actual duty and ordered-equipment scope.
SASPG · JIANYANG, CHENGDU, SICHUAN
Connect the compressor offer to its actual manufacturer
四川空分设备（集团）有限责任公司 traces its plant history to 1966. Its businesses cover cryogenic research, engineering, cryogenic equipment, industrial gases and general machinery. The official site assigns reciprocating-compressor manufacture to subsidiary 四川简阳川空通用机械设备有限公司.
The group and subsidiary are separate legal identities. Define the contracting entity, offered manufacturer and equipment scope on the proposal and acceptance records. Group engineering, cryogenic equipment and certificate descriptions do not automatically apply to every compressor.
TWO MW EXAMPLES · DIFFERENT PROCESS CAPTIONS
Give each process machine its own performance sheet
MW-36.3/10 natural gas
The gallery identifies this model, but does not supply a complete flow, pressure and power table. Model-code numbers are retained as identifiers, without decoding a guaranteed duty.
Supply gas composition, inlet temperature/pressure envelope, liquids and contaminants, volume reference, delivery pressure and process cycle. Request stage duties, power, cooling, materials/seals, lubrication and protective controls.
MW process and package-selection details →MW-2.1/18-201-6.0/12-201
The separate source caption calls this a high-pressure-process liquefied-natural-gas compressor. Define the actual gas phase and inlet conditioning; the process label is not an instruction to feed uncontrolled liquid.
Agree the compressor’s position in the process, stage suction/delivery conditions, separation/drain interfaces, control sequence and package scope. It does not inherit the MW-36.3/10 rating or a complete LNG plant scope.
STATION SOURCE · AIR DUTY · LUBRICATION BOUNDARY
CNG and high-pressure air need different inputs
CNG station proposal
- Source: pipeline inlet conditions or trailer/storage pressure over time, composition and temperature.
- Demand: required delivery pressure, reference flow, average/peak filling and storage/sequencing.
- Package: capacity/power curve across suction conditions, cooling, liquid handling, vents, interlocks and hazardous-area scope.
LNG/L-CNG station equipment is a separate group scope. Confirm which coolers, vessels, piping, controls and station accessories are actually included.
CNG duty and supplied-equipment checklist →2V-1/350-CK high-pressure air
This exact model caption belongs to the enclosed-machine photograph. The code is not decoded into a flow or discharge-pressure guarantee.
- Specify intended use, gas, inlet/ambient conditions, volume reference, receiving pressure and duty cycle.
- Agree acceptable oil, moisture and particles, stages, cooling/interstage separation and supplied treatment.
- Define receivers/pressure-system responsibility, relief protection, electrical interfaces and ordered-machine tests.
A separate oil-free nitrogen/air example
The trial caption does not establish the 2V model’s lubrication arrangement. The subsidiary also describes non-lubricated cylinder technology for oxygen and high-purity-gas products.
Specify the chosen machine’s gas-path design and contamination criteria. “Non-lubricated cylinder” does not mean every drive or bearing mechanism is lubricant-free; a broad media list is not approval for every mixture or operating condition.
EQUIPMENT SCOPE → DOCUMENT SCOPE → HANDOVER
Keep pressure, cryogenic and compressor responsibilities explicit
The subsidiary’s wider portfolio includes cryogenic valves, pressure vessels, LNG/L-CNG stations, vacuum piping and gas cylinders. Identify the ordered equipment, not just the group brand.
| Boundary | Required definition |
|---|---|
| Compressor package | Compressor, driver, cooling/separation, gas piping, controls, protection and any enclosure; actual duty and off-design limits. |
| Pressure and process equipment | Vessels, relief, receivers and cryogenic accessories; applicable legal manufacturer, documents and destination requirements. |
| Acceptance and installation | Performance/test conditions, witness points, model/serial-linked results, foundation/lifting, utilities and maintenance clearances. |
| Ownership and service | Manuals, commissioning/training, wear-parts lists, warranty terms, destination attendance and cost responsibilities. |
SASPG’s quality page describes group metrology, physical/chemical examination, inspection and testing resources and publishes certificate images. For an offer, obtain documents with the correct holder, validity, product and destination scope.
Questions for a SASPG compressor proposal
Does the group’s 1966 history identify the compressor subsidiary’s incorporation date?
No. It is the group’s plant-history statement. The official general-machinery description separately identifies the subsidiary; obtain the contracting/manufacturing identity for the order.
Can 40 or 42 MPa be applied to every CNG or MW package?
No. They are portfolio upper descriptions on different pages. Use the selected machine’s duty sheet and complete inlet/delivery envelope.
Is the oil-free nitrogen/air trial the same as 2V-1/350-CK?
The gallery provides separate captions and photographs. Specify the offered 2V lubrication and treatment arrangement rather than assigning another example’s description.
Specify the process, then the package
Send MW natural-gas, CNG station or 2V air duty, the gas/suction envelope, required delivery, site utilities and ordered-equipment scope.

Specification pages for SASPG product types
| Duty | Write on the RFQ |
|---|---|
| Compressor for PET bottle blowing | Bottle blowing is a high-pressure oil-free process. The blower OEM’s pressure and the cavity count size the compressor, not the word PET. |
| Process gas compressor manufacturers in China | Process gas is not plant air. Molecular weight, suction pressure, discharge pressure and flow size the machine. A kW from an air catalogue is unused. |
| 30 bar oil-free compressor | Specify whether 30 bar is gauge or absolute pressure, where it is required and how much air must be supplied at that point. A 30 bar working duty does not, by itself, identify a compressor architecture, motor size or air-quality class. |
| 40 bar PET compressor | PET blowing at 40 bar(g) is a high-pressure oil-free duty. Cavities, bottle volume and recovery pressure size the skid — not the word “PET compressor”. |
