Manifolds and Valves

Stainless and Hi-Nickle Alloy Manifolds are our specialty. For over 30 years we have been producing pulled outlet manifolds for reverse osmosis and ultra-filtration systems. We pull and weld manifolds or pipe spools from OD tube Schedule IPS 5-10-40 and guarantee the highest profile in the business. Our process is consistent and precise, pulling the outlets to 1/2" to 12" diameter pipe, plus our tolerances are much tighter than industry standards.

We take pride in our production of manifolds resulting in ZERO bowing or twisting. Wall thinning is a concern for other companies that use a spinning mandrel technic and have 25% to 40% thinner walls plus gouging of pipe walls can occur. With our superior techincs in the production of manifolds, we can claim wall thinning as low as 10% without gouging or harming the pipe walls.
