RO Membrane Pressure Vessels (FRP)
أوعية ضغط أغشية RO من FRP
Product Description
The right membrane pressure vessel must match element size, array length, port layout and operating pressure, and DSTC helps select the housing before replacement or new build. Beyond supply, we help match the vessel to your membranes and pressure, and stock spares such as end caps, O-rings, retainer rings and saddles.
For quotation, send element size (4040 or 8040), number of elements per vessel, pressure class, port type, preferred brand, quantity, spares needed and delivery city.
Overview
RO membrane pressure vessels are fiberglass (FRP) tubes that hold reverse osmosis membrane elements and safely contain operating pressure. The correct vessel depends on element size, number of elements per housing, system pressure and port type. DSTC supplies 4-inch vessels for one 4040 element and 8-inch vessels for one to six 8040 elements, rated at 300, 450, 600 or 1200 psi, in side-port and end-port designs from Pentair, Codeline and UKL. DSTC also carries vessel spares and helps select the correct size, pressure class and port type for new builds, re-racking and replacements.
Applications
- •Seawater desalination (SWRO) trains that require 1200 psi vessels for high-pressure membrane operation
- •Brackish water RO (BWRO) systems running at 300, 450 or 600 psi pressure classes
- •Industrial and commercial RO skids housing 8040 elements, with one to six elements per 8-inch vessel
- •Small commercial and point-of-use RO units using 4-inch vessels for a single 4040 element
- •Replacing corroded or fatigued vessels and re-racking existing RO plants in Jeddah, Riyadh, Dammam, Jubail and Yanbu
- •Water bottling, process water and boiler feed RO systems that need reliable FRP membrane housings

Frequently Asked Questions
Which vessel size do I need for my membranes?+
Use a 4-inch vessel for one 4040 element and an 8-inch vessel for 8040 elements.
How many membrane elements fit in one 8-inch vessel?+
DSTC supplies 8-inch vessels for one to six 8040 elements.
Which pressure class should I choose for seawater versus brackish water?+
SWRO usually needs 1200 psi. BWRO usually uses 300, 450 or 600 psi.
What is the difference between side-port and end-port vessels?+
End-port vessels connect through the end caps; side-port vessels connect near the ends on the side of the shell.
Do you supply vessel spare parts on their own?+
Yes. DSTC stocks end caps, membrane adaptors, head-seal O-rings, retainer rings, saddles, straps and thrust cones.
