Natural Gas Pressure Regulating & Metering Skid

Product Overview

HUAYI Natural Gas Pressure Regulating & Metering Skid is an integrated skid-mounted system designed for natural gas distribution, industrial gas supply and pipeline branch applications.

The system can combine gas filtration, pressure regulation, flow metering, safety protection, instrumentation, valves and process piping within a factory-assembled skid configuration. Compared with installing individual process components separately on site, the skid-mounted arrangement helps simplify equipment integration, site installation and commissioning.

The system configuration can be engineered according to project-specific gas flow, inlet and outlet pressure, gas composition, operating conditions, metering requirements and control philosophy.

Typical System Configuration

Depending on project requirements, a Natural Gas Pressure Regulating & Metering Skid may include:

• Gas filters or filter separators

• Pressure regulating valves

• Gas flow meters

• Safety shut-off devices

• Pressure relief devices

• Isolation and process control valves

• Pressure and temperature instruments

• Process piping and manifolds

• Skid base and supporting structure

• Optional PLC control and monitoring system

• Optional communication interface for remote monitoring

The actual equipment configuration and quantity are determined according to the required process conditions and project specifications.

Key Functions

Gas Filtration

The filtration section is designed to remove solid particles and, depending on the selected filtration equipment, entrained liquids from the natural gas stream. This helps protect downstream pressure regulating valves, flow meters and other process equipment.

Pressure Regulation

The pressure regulating section reduces the incoming gas pressure to the required downstream operating pressure. Single-train or multiple-train configurations can be selected according to gas flow, operating philosophy and redundancy requirements.

Gas Flow Metering

Different metering technologies can be selected according to the required flow range, operating pressure, measurement requirements and project specifications. Typical options may include turbine, ultrasonic or other suitable gas flow meters.

Safety Protection

The skid can be configured with safety shut-off, pressure relief and associated pressure monitoring devices according to the process design and applicable project requirements. These devices support downstream pressure protection and safe system operation.

Instrumentation and Control

Pressure, temperature, flow and other operating parameters can be monitored through field instrumentation. Where required, the skid can also be equipped with a PLC-based control system and communication interfaces for centralized monitoring, alarm management and data transmission.
