High-Pressure Natural Gas Regulating & Metering Skid

Product Overview

HUAYI High-Pressure Natural Gas Regulating & Metering Skid is an integrated gas handling system designed for high-pressure natural gas transmission, distribution and industrial gas supply applications.

The system can integrate gas filtration, gas heating, ultrasonic flow metering, pressure regulation, instrumentation, valves and process piping within a skid-mounted configuration. It is particularly suitable for applications involving high inlet pressure, large gas flow rates and project-specific downstream pressure requirements.

Each system is engineered according to the required gas flow rate, inlet and outlet pressures, gas composition, operating temperature, metering requirements, site conditions and applicable project specifications.

Reference System Configuration

A reference system configuration includes:

• 1 set of integrated filtration, metering and pressure regulating skid

• 2 vertical gas filters

• 2 ultrasonic flow meters

• 2 hot-water circulation heat exchangers

• 6 pressure regulators

• Process manifolds and piping

• Control and isolation valves

• Pressure and temperature monitoring instruments

• Associated instrumentation and control components

• Mounting and connection accessories according to the agreed supply scope

Reference Technical Parameters

The above parameters represent a reference project configuration. Final process parameters, equipment arrangement, materials and component selection are determined according to project-specific operating conditions and technical requirements.

Key Functions

Gas Filtration

Vertical gas filters remove solid particles and other impurities from the natural gas stream to help protect downstream metering, pressure regulating and process equipment. The filtration arrangement is selected according to gas conditions and project requirements.

Gas Heating

Hot-water circulation heat exchangers provide gas preheating and temperature control where required. This helps manage the gas temperature reduction associated with pressure regulation under high-pressure operating conditions.

Ultrasonic Flow Metering

Ultrasonic flow meters provide gas flow measurement for high-pressure and large-flow applications. The final metering configuration, meter specification and measurement requirements are determined according to the project flow range, operating conditions and applicable standards.

Pressure Regulation

Multiple pressure regulators provide controlled pressure reduction according to the required inlet and outlet operating conditions. The final regulator arrangement and control philosophy are determined during project engineering.

Instrumentation and Control

Pressure and temperature monitoring instruments, valves and associated control components can be integrated into the skid according to project requirements. Interface requirements with the customer's control system can be defined during technical clarification.
