Welded Steel Casing Pipe.Carbon steel casing pipe,also known as encasement pipe,is welded with a straight seam using the double submerged arc welding process,or DSAW,for a full penetration weld.DSAW is the most reliable welding process for producing thick-walled pipes.(PDF) HAP - Best practice penstocks Valeri Georgiev In one plant studied where the penstock is 130 feet long a net gain of head of 0.65 feet could be realized by replacing the riveted penstocks with welded steel,spun-tar lined penstocks.The generation gain would be more than one million kWh per year . Surface roughness reductions can also be achieved by coating the inside of the penstock.
