CE Certificated Double Membrane Gas Holder for biogas plants
YHR is a Chinese National High-Tech Enterprise with more than 200 employees. We started our research of Glass-Fused-To-Steel Technology since 1995, we built the first China-Made Glass-Fused-To-Steel Tank independently in 1999.
Nowadays we are not only the leading Bolted Glass-Fused-To-Steel Tanks manufacturer, but also an integrated solution provider of biogas engineering in China.
YHR is expanding oversea market rapidly, our GFS Tanks and equipment has been delivered to more than 20 countries.
YHR gasholders use a double membrane strucutre
The outer membrane is a permanently inflated textile structure. The membrane is inflated by the use of electrically operated blowers – usually specified in matched pairs for Duty/Standby cycles. Non-return valves are fitted in the air supply line to isolate each blower when in standby mode. A regulator valve is fitted on the outer membrane exhaust duct.
The inner membrane forms the variable volume gas containment within the outer membrane. The inner membrane and bottom membranes are sealed with a gas-tight compression seal around the periphery of the structure on the concrete base. As the volume of stored gas increases, the inner membrane rises to accommodate it. The pressure within the gas containment, and therefore the gas pipelines, is maintained by the air pressure within the outer membrane bearing on the surface of the inner membrane. The pressure differential across the outer air containment and inner gas containment is minimal – due only to the weight of the inner membrane (the gas containment pressure is 0.145 – 0.022psi (1 to 1.5 mBar higher)).
