Common Issues in Double Membrane Gas Holders 

Here are some common issues with double membrane gas holders and their corresponding solutions:

Two factors that can cause damage to a biogas double membrane gas holder (double membrane gas storage tank) are:

Excessive Positive Pressure: When the internal pressure in the double membrane gas holder exceeds its capacity, it can lead to air leaks, membrane rupture, or pipe breakage.

Excessive Negative Pressure: If the negative pressure inside the gas holder surpasses its tolerance, it may cause damage to the inner membrane.

In addition, prolonged use can lead to rubber seals aging and wrinkling. The inner membrane of the double membrane gas holder may also become stretched due to fluctuating gas volumes, and with friction and tensile forces, this can lead to membrane damage and leaks.

For instance, the Qingdao Haiyue double membrane biogas gas holder with enamel-assembled tank requires regular maintenance checks. Therefore, even when using a double membrane gas holder, regular leak inspections are essential to ensure its seal integrity.

Emergency measures in case of a leak in a double membrane gas holder are as follows:

Immediately cease use and initiate repairs.
If a leak is detected, release the biogas from the gas holder and fill it with sufficient air. Then, use soapy water to check for leaks and identify the leaking area for sealing. If the issue lies with loose bolts on the membrane and pressing plate, tighten the bolts to prevent leakage due to loosening or detachment. If the membrane material is damaged, replace it promptly.

Repair the leak and conduct a safety inspection.
After repairing the leak, thoroughly inspect the entire gas holder system to ensure there are no other leakage points. Only after confirming no leaks should biogas be reintroduced, followed by an airtightness test to ensure the gas holder is secure.

Regular maintenance.
Regular inspections and maintenance of the double membrane gas holder are essential. Replace any parts as needed and conduct airtightness tests periodically to maintain operational safety.

Established in April 2012 in the coastal city of Qingdao, Haiyue Biogas specializes in the development and production of double membrane gas holders, GFS assembly tanks, and other environmental and new energy equipment. Over the past decade, we have become a leader in China's double membrane gas holder and GFS tank industry, thanks to our commitment to innovation and customer service.
