Natural Gas Pressure Regulating & Metering Cabinet

Product Overview

HUAYI Natural Gas Pressure Regulating & Metering Cabinet is an integrated gas supply unit designed to provide filtration, pressure regulation, safety protection and optional flow metering for downstream gas users.

The equipment can be used between the upstream gas distribution pipeline and downstream commercial or industrial gas systems where controlled and stable gas pressure is required.

The cabinet configuration can be engineered according to gas flow capacity, inlet pressure, required outlet pressure, gas composition, installation environment and project specifications.

Typical System Components

Depending on the selected configuration, the system can include:

• Gas inlet and outlet isolation valves

• Gas filter

• Pressure regulator

• Safety shut-off device

• Safety relief device

• Pressure gauges and instrumentation

• Gas metering equipment where required

• Associated process piping and valves

• Single or multiple regulating lines

• Bypass arrangement where required

• Protective enclosure or cabinet

Final equipment configuration is determined according to the specific project requirements.

Pressure Regulation

The pressure regulating section reduces the upstream gas pressure to the required downstream operating pressure and maintains controlled gas supply conditions within the designed operating range.

Pressure regulator selection and configuration are determined according to the required gas flow, inlet pressure range, outlet pressure and operating conditions.

Gas Filtration

An upstream gas filter can be incorporated to remove solid contaminants from the gas stream and help protect downstream pressure regulators, metering equipment, valves and instrumentation.

Filter type and filtration requirements can be selected according to the gas conditions and project specifications.

Gas Metering

Where gas consumption measurement is required, the cabinet can incorporate suitable gas metering equipment.

Meter type, measuring range, instrumentation and communication requirements can be selected according to the required flow range and project specifications.

Safety Protection

Depending on the project configuration, the system can incorporate safety shut-off and pressure relief devices to provide protection against abnormal downstream pressure conditions.

The required protection philosophy and set points are determined during project engineering according to the operating conditions and applicable specifications.

Single-Line or Multi-Line Configuration

The cabinet can be configured with single or multiple gas regulating lines according to the required gas supply capacity and operating philosophy.

For applications requiring increased operational availability, parallel regulating lines can be considered according to project requirements.

Enclosure Options

The pressure regulating and metering equipment can be installed within a protective cabinet suitable for the intended installation environment.

Enclosure material and configuration can be selected according to project requirements, including options such as stainless steel or other suitable materials.

Indoor or outdoor configuration can be considered according to the site conditions and project specifications.

Typical Applications

The Natural Gas Pressure Regulating & Metering Cabinet can be configured for applications including:

• Commercial natural gas supply

• Industrial gas supply systems

• Boiler and heating gas supply

• Local gas distribution networks

• Industrial facilities
