For shorter pipe spools it is not really practical to supply spools with flanges as either the nuts / bolts do not fit or there is insufficient space for flanges or both. For these short lengths we supply spacers, these are a wafer style designed to be bolted between two mating flanges. The outer diameters of the spacers corresponds with I.B.C. dimensions to fit snugly within the joint. To maintain the appropriate working pressures whilst keeping costs down we use three different types depending on the length for each given nominal bore.
Type 1 for the shortest lenghts produced from solid PTFE bar.
Type 2 for intermediate lengths with a PTFE lined spacer bar produced form steel.
Type 3 for longer spacers with a PTFE lined pipe with welded stub ends.
