Structural Design of Decompression Skid with Heat Exchange Integration 

Our decompression skid products integrate multi-stage heat exchangers seamlessly into a compact, modular structure. The skid design includes primary and secondary heat exchangers, pressure regulators, and safety valves, all interconnected to facilitate a smooth decompression process. For example, CNG enters the primary heat exchanger to absorb heat from a hot water circulation system before undergoing the first pressure reduction stage. This integrated design minimizes energy loss and ensures consistent performance, even in low-temperature environments.

Safety and Reliability of Decompression Skid in Pressure Regulation 

Safety is a top priority in our decompression skid design. Multi-stage heat exchange systems include built-in safety features such as emergency shut-off valves, overpressure relief mechanisms, and real-time temperature monitoring. These components work together to prevent overheating, pressure surges, or gas leaks during decompression. Additionally, the skid’s robust construction and corrosion-resistant materials ensure long-term reliability in harsh operational environments, reducing maintenance needs and enhancing system longevity.

Decompression Equipment FAQS

How Does Multi-Stage Heat Exchange Improve Decompression Equipment Performance? 

Multi-stage heat exchange in Hebei Ouyinuo’s decompression equipment ensures gradual, controlled cooling of CNG during decompression. Each stage adjusts the gas temperature to prevent condensation or freezing, which could disrupt flow or damage components. By maintaining stable temperatures, the system enhances decompression efficiency and reduces the risk of operational failures, ensuring a consistent gas supply to consumers.

Can Decompression Skid Systems Handle High-Pressure CNG?

Yes, our decompression skid is designed to safely manage high-pressure CNG inputs. The multi-stage heat exchange system preheats the gas to withstand the thermal stress of rapid decompression, while pressure regulators gradually reduce pressure to safe levels (e.g., from 20 MPa to 0.1–0.4 MPa). This phased approach ensures that the skid can handle even the highest-pressure CNG sources reliably.

What Maintenance Is Required for Multi-Stage Heat Exchange Decompression Equipment? 

Maintenance for our decompression equipment is streamlined to minimize downtime. Regular checks on heat exchanger tubing for scaling, valve tightness, and water circulation efficiency are recommended. The skid’s modular design allows for easy replacement of individual components, such as heat exchangers or pressure regulators, without disrupting the entire system. Routine inspections and timely cleaning ensure optimal performance and longevity.

How Do We Ensure the Safety of Decompression Skid Systems? 

Safety is embedded in every aspect of our decompression skid design. We integrate interlocking controls that monitor pressure, temperature, and flow rates in real time, automatically shutting down the system in case of anomalies. Additionally, all components comply with international safety standards (e.g., GB27790), and the skid undergoes rigorous testing for leak resistance and thermal stability before deployment.

Are There Customization Options for Decompression Equipment Heat Exchange Stages? 

Yes, Hebei Ouyinuo offers customizable decompression equipment to suit specific project requirements. Clients can choose between two-stage or three-stage heat exchange systems based on gas flow volume, pressure reduction needs, and environmental conditions. For example, systems in colder regions may include additional heating stages to prevent icing, while high-flow applications might require larger heat exchangers to maintain efficiency. Our team works closely with clients to tailor solutions that meet their unique operational demands.
