The Spherical Misalignment Assembly is comprised of two misalignment female weld neck flanges, two spherical seal rings, a spherical male adapter, and a complete set of studs and nuts.Because of the allowable misalignment, spherical washers are installed to reduce stress on the studs. This technology is based on the “double ball joint” shape of the spherical male adapter, which allows for both axial and angular misalignment of piping.

This Spherical Misalignment Assembly configuration has many applications:

• Alleviate misalignment problems anticipated due to welded construction
• Easy to assemble high-pressure connections between skid mounted units in field
• Easy removal of heavy thick-walled, high-pressure elbows without moving mating flanges 
• Installation of 90° elbows in tight spaces
