Gas application

Testing and stop-off bags
for gas

All products meet the requirements of highest quality and safety standards and are GS-marked.
This include the processing of a high quality natural and synthetic rubber compound, reinforcing
with a rayon kevlar fabric and with corrosion resistant filling cuplings and holding rings.

 

 

Carefully selected suitable fabric materials are converted into our highly functional stop-off bags
at our German works. The inside rubber layer confirm to all industrial standards and the DVGW regulations.

 

 

 

 

MDA™ 1 bar - Multi dimensional Gas stop-off bag

  • with DVGW approval DG 4520BRO183
  • designed for manual positioning or for the use in combination with bag positioning devices
  • connection depending on bag positioning device i.e. S+B, VEW double bag positioning device etc

MDA™ stop-off bags are made from an unique rubber

  • designed to allow especially high internal pressure
  • even for DN 300 bags the maximum counter pressure is 500 mbar, which is truly unique for stop-off bags of this type

 

MDA™ 1 bar - Multi dimensional stop-off bags are available as

  • single bag with and without pressure measurement
  • as double bag with tension release of the space between bags
  • as bag for manual positioning with T-piece, ball valve, pressure gauge and conical rubber stopper

 

In comparison to conventional textile testing and stop-off bags, the new MDA™ bags offer a number of vital advantages such as:

  • excellent gas tightness due to a special rubber type
  • perfect positioning of the bag as soon as pressure is applied in combination with extreme mechanical resistance
  • conical shape for superior flexibility and easy insertion even through bends
  • highly resistant against temperature, oil and chemicals
  • designed for easy positioning with MDA™ bag positioning devices up to 1 bar
  • compatible with practically all bag-positioning devices available
  • max. back pressure: 1.0 - 0.5 bar

 

Due to their temperature and chemical resistance MDA™ bags are ideal for stopping-off

  • long-distance energy pipelines
  • pipelines of the chemical industry
