Biogas Pipeline Connection fittings

Biogas Pipeline Connection fittings

Biogas naturally contains water vapor.When  it  flows  through  a  pipe,  some  of  the  vapor condenses as liquid water, and if it is left in the pipe, it will eventually collect and block the gas flow.The solution is a water trap, a simple device which allows the water to escape. It should be fitted to biogas pipes wherever there is a local low point of the pipe where water naturally collects. And  pipes  should  be  laid  so  that  these  low  points are at easily accessible positions. The water trap consists of a T-joint running a short tube down from the main tube into a small container full of water. The  pressure  of  the  water  prevents  gas  from escaping. The water level should be approximately 15cm  (equivalent  to  150    mbar)  to  ensure  no  gas loss. The  container  could  be  a  plastic  water  bottle  for example. As  it  fills  with  water  it  will  slowly  overflow,  so  the location  should  be  one  where  a  small  amount  of water  leakage  is  okay.  An  inspection  hole  in  the ground, for example, works well.
