UHP Pre-fab manifolds are designed to meet all UHP cleanliness specifications. UHP laterals are fabricated using a pulled-tee method then welded, tested and packaged in a class 10 cleanroom environment. This method of fabrication reduces the number of welds typically required by over 65%. Cost, time pressure and lack of skilled labor combined with ever increasing demands on high quality gas systems call for new ways of cooperation. Drilling and collaring combined with proprietary welding technology reduces overall costs by over 30%.
