The semiconductor GAS tubes and tubular fitting is for high-purity operations. CSE can provide tubes and fittings produced in Class10,000 clean rooms with Electric polish Ra

The vacuum component is a flanged vacuum assembly, which consists of a fixed flange at one end of the pipe or a fixed flange at one end and a rotatable flange at the other end of the pipe (on the CF flange assembly). This rotatable vacuum flange avoid the problems of the bolt holes of the mating fittings or flanges. Butt-welded pipe fittings consist of 304 or 316L stainless steel pipes, including elbows, reducers, tees, seals, clamps, hoses, flanges, pipes, and fittings.
