Bryan donKin rMg gas Controls liMited


1

Bryan Donkin RMG, have successfully engineered Gas Pressure Reducing and Metering Stations for over 40 years embodying the extensive range of gas control equipment manufactured by the Company and RMG Group of Companies.

Skid mounted, pre-packaged units are designed and built to meet individual customer requirements and specifications. Units range from Domestic Meter Boxes to High Pressure Class 600 stations.

Units have been supplied worldwide to a range of industries including Gas, Steel, Process and Chemical etc. All designs take account of modern practices in the control of gases and incorporate safety features to provide a unit of high integrity. Factory built units are pre-tested giving a high level of Quality Assurance, whilst simplifying on-site installation/commissioning and providing considerable savings in manpower.

service governor Modules:

The Service Governor Modules (SGM) contained in this publication are a space saving range of standard designs for use on District, Industrial and Commercial services for pressures up to 7 barg, providing the flexibility to meet the requirements of IGE/TD13 and T/SP/E34.

Features:

• Inlet & Outlet Isolating Valves • Regulator • Safety Cut-Off Valve • Creep Relief Valve • Above & Below Ground Options

Benefits:

• Pre-Packaged Ready to Install. • Minimum Labour • Easy to Handle • Pre-Tested

application

• The VS3 vent stack is designed to carry relief valve outlet pipes and other breather pipes from underground pressure reduction installations to a high above ground location.

• The underground installation may be a buried module or a pit mounted module.

• The installed height of the stack is approximately 3 meters, it has a weather proof cap to prevent the ingress of water or blockage with insects etc.

• The inside diameter of the stack is approximately 80 mm, from a single or twin stream installation it will accommodate the relief valve outlet (32 mm pe pipe) together with, if required, breathers from the regulator, slamshut and relief valve.

site selection

The vent stack may be the only visible above ground part of the pressure reduction installation.

• Locate away from roadways and possible vehicular traffic, a fenced compound is preferred but not essential.

• Locate away from areas liable to prolonged overhead water drips during winter thaws, this will help prevent icing.

• Locate reasonably close to the station to shorten lengths of pipe runs but away from buildings where any vented gas would cause problems.

installation

These recommendations are not intended to over ride the requirements of any applicable code of practice or any regional code. If an operation is covered by an approved code then that code should be followed.

Run the vent and breather pipes to the top of the stack cutting the ends at 45 degrees as shown in the illustration.

Small breather pipes will normally be installed within a length of 20 or 32 mm (PE) ducting entered up inside the stack.

Prop the stack vertically and cast around the base a 500 mm square of concrete approximately 300 mm deep or as the site dictates for stability. The base elbow should be incorporated within the concrete to provide an anchorage and prevent rotation.

Corrosion Protection

The VS3 stack is supplied galvanised to BS 729 at 85 micron min. thickness and normally requires no further above ground protection. The buried portion may, if desired, be over coated with bitumastic for additional protection.

Vent Stack

Note: Cast in situ a 500mm concrete block lay ducts to the access opening prior to casting the block
