Multiple arch - standard joint with 2 or 3 arches. Recommended for greater movement where face to face dimensions are not limited. Suitable for pressure or vacuum applications with flanges or sleeve ends.
Light weight - recommended for handling air, liquid, gases and fumes at 7.5 [ 15"vacuum absolute ] to 15 psi. Available with multiple arches, filled arches and sleeves ends.
Retaining rings - use of split-steel rings assure a pressure-tight seal. Outside diameter is same as standard flange and contains the same number of bolt holes. Those used on joint sizes upto 40" are two-piece [ 4 segments per joint ]. Four-piece rings [ 8 segments per joint ] are used on all larger sizes. All are generally 3.8" thick.
