Hi all,
I am working to implement biogas in East Africa, and I’m curious about whether there is a preferred plastic polymer for use in plastic biogas pipework. Most affordable, readily available plastic pipes and fittings are made from PVC (polyvinylchloride), PE (polyethylene), or PP (polypropylene). - Is one of these materials better than the other two for use in gas lines? And is there a material that should be avoided for use in biogas pipework (i.e. due to chemical corrosion, UV damage, or creep?) - In particular, I am concerned about the accumulation of white (silica?) deposits in biogas pipework. Does the use of plastic piping reduce the buildup of this white substance? And very specifically, does this white substance accumulate on PP fittings? Any thoughts on these two questions are very much appreciated. Thanks, Chandler
