Pistion compressor

Product Description:
Piston compressors are positive displacement machines that use a piston and cylinder to compress gas. They are a cornerstone of the chemical and petrochemical industries, valued for their robustness, high efficiency, and ability to achieve extremely high discharge pressures. Their relatively simple maintenance requirements and adaptability to various gases make them a versatile choice for many process applications.
Our company's compressors are designed and manufactured in accordance with either API618Standard  (the internationally recognized reciprocating compressor standard established by the American Petroleum Institute) or the Chinese national standard GB/T 20322-2023 Reciprocating process compressors for petroleum, petrochemical, and natural gas industries. In addition, we apply the following supplementary Chinese standards to ensure comprehensive compliance:
GB/T 25357-2010 – Petroleum, petrochemical, and natural gas industries – Positive displacement rotary compressors for process service. This standard applies to rotary compressors such as screw-type units.
JB/T 8935-2014 – Safety requirements for process compressors. This is a general safety code covering all types of process compressors, including reciprocating, centrifugal, and rotary machines.
JB/T 9105-2013 – Technical specifications for large reciprocating piston compressors. Serving as a supplement to GB/T 20322, this standard sets forth more specific requirements for large reciprocating units.
These standards together form a robust framework that aligns our products with both international best practices and domestic regulatory requirements

Diaphragm compressor

 Diaphragm compressor, also known as a membrane compressor, is a special type of reciprocating compressor. Its defining feature is the use of a flexible diaphragm (typically made of metal or non-metallic materials) that reciprocates within the cylinder to compress and transport gas. Diaphragm compressors are a specialized type of positive displacement compressor. They use a hydraulically driven metal diaphragm to compress the gas, achieving absolute oil-free compression and zero leakage. This hermetic seal makes them the premier choice for handling high-purity, flammable, toxic, or expensive gases.

This design ensures complete isolation between the gas being compressed and the mechanical moving parts of the compressor, preventing any contamination or leakage.

the diaphragm compressor offers the following significant advantages

100% Oil-Free Discharge: Prevents product contamination.
Ultra-High Purity: Ideal for semiconductor and hydrogen fuel cell applications.
Excellent Leak-Tightness: Enhances safety for hazardous gases.
Compression of Dry Gases: Handles gases with no lubricating properties.

FAQ

Q1: What are the critical advantages of a diaphragm compressor over a piston compressor for high-purity hydrogen service?
A: The diaphragm compressor's hermetically sealed design ensures zero gas leakage and 100% oil-free compression. This prevents contamination of the hydrogen stream (crucial for fuel cell applications) and eliminates the risk of oil-catalyzed reactions. It also offers superior safety for flammable gases and longer maintenance intervals on wearing parts compared to piston rings.

Q2: How is the compressor certified for safety, especially for hydrogen applications?
A: Our compressors are designed and manufactured under a stringent Quality Management System certified to ISO9001:2015, ISO14001, and ISO45001. For the international market, our products hold CE certification. We also implement rigorous ATEX-compliant design for hazardous area zones as per your project requirements, including integrated gas detection, ventilation, and emergency shutdown (ESD) systems. Material selections are specifically vetted to prevent hydrogen embrittlement.

Q3: What is the typical Maximum Allowable Working Pressure (MAWP) and flow rate?
A: Our standard diaphragm compressor series can achieve discharge pressures up to 90 MPa (900 bar) . For piston compressors, custom designs can reach even higher. Flow rates are application-dependent; for hydrogen refueling, capacities range from 100 to 2,000 Nm³/min. For production, we can engineer units with capacities exceeding 2,000 Nm³/min. The final specification is always matched to your precise inlet/outlet conditions.

Q4: Can you detail the standard materials of construction for the wet gas end?
A: Yes. To ensure durability and process compatibility:

Cylinder / Cylinder Head: Forged alloy steel (e.g., ASTM A350 LF2 or 4340), heat-treated to minimize hydrogen embrittlement risk.
Diaphragm (for diaphragm compressors): High-nickel alloy (e.g., Inconel® 625 or similar) for maximum fatigue life and corrosion resistance.
Valves: Stainless steel with hardened seats.
Piston Rings (for piston compressors): Self-lubricating, non-metallic materials (e.g., PTFE-based) to reduce wear and contamination.

What is your engineering capability? Do you use simulation tools?

Can you provide a turnkey skid-mounted package?

Yes. Our technical team utilizes advanced Digital Analog Computing for thermodynamic performance simulation, Finite Element Analysis (FEA) to validate pressure-containing component integrity, and specialized software for pulsation analysis to ensure piping system reliability. This allows us to provide verified performance data and safe, stable operation before manufacturing begins.
Q6: 
A: 

Absolutely. We offer complete skid-mounted compressor packages, including the compressor, motor, cooler, lubrication system, pulsation dampeners, piping, and local control panels. This simplifies site installation, reduces civil works, and ensures a single-point responsibility for the entire compression system.
