FOR DETAILED PRODUCT
INFORMATION AND SPECIFICATIONS
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%.

Evans Components, Inc. was the first to introduce a High Purity Valve for use in the Semiconductor marketplace.
Evans DM Series purge tools provide an economical, reliable, compact solution for manifolding UHP Argon purge gas. Manifold is machined out of solid block, eliminating multiple NPT/mechanical connections which reduces cost and eliminates potential leakage which can cause discoloration/contamination of the weld. All purge tools are helium leak tested to 1 x 10-9 scc/sec and guaranteed to a dry down rate of less than 10 ppb.

The Eco-Purge solves what has become a significant cost impact to companies installing high purity electropolished and/or general purity large diameter tube/pipe. High usage of purified Argon gas for purging and wait times for Oxygen evacuation of tube I.D. consumes large amounts of gas. The Eco-Purge reduces > 90% in purge gas consumption, > 65% reduction in time for purging/welding, in-situ oxygen and I.D. pressure monitoring ensure consistent high quality color free welds.
