4” End Port FRP

Protec Arisawa Fiberglass Membrane Housings

Protec ariswa pressure vessels are designed for continuous use as housing for membrane filtration elements to purify typical waters at any positive pressure ratings from 300 PSI up to 1000 PSI. Protec vessels will accommodate any make of four-inch nominal diameter spiral-wound element as well as many hollow fiber elements. The element interface hardware for the specified element is supplied with the vessel.

Protec ariswa pressure vessels have been designed to meet the standards of the American Society of Mechanical Engineers (ASME), Boiler and Pressure Vessel Code, Section X. At an additional cost, vessels can be inspected during fabrication by an ASME Authorized Inspector and Code stamped.
