3M™ WT Housings are our high quality, low cost pressure vessels. They’re typically constructed from 304L and 316L stainless steel, and can be supplied with a wide range of in-contact materials and connections types.
3M™ WT Housings are designed for use with 3M™ CTG-Klean™ filter elements. They’re suitable for most industrial applications where operator contact with the process fluid should be minimised. Special builds 3M West Europe SPSD Hardware team have extensive experience of designing special vessels for filter applications. We can produce them in a wide variety of design and construction codes (including ASME U Stamp). Our special vessels can range from simple modifications of standard designs up to large multiple housing skid mounted units with associated accessories, and with both second shell heating jackets and electrical trace heating. The information in the following sections is typical for standard products – please contact your local 3M SPSD representative for further information.

Typical operating conditions for the housings are up to 10 bar g and temperatures of up to 70 °C. Actual operating temperatures and pressures will depend on the cartridge types and on the PED 2014/68/CE regulations that are applicable to all pressure vessels. PED 2014/68/CE 3M WT vessels are routinely produced for Categories up to and including PED Cat IV. Construction materials 3M WT vessel shells – that are not in contact with the process fluid – are produced in 304L. Typically, all wetted surfaces are 316L stainless steel. Other parts are supplied in 304 stainless steel or similar. Special builds can be with the wetted – in contact – parts from the material of the customer’s choice, including Super Duplex varieties (Uranus B6).
