8 inch Stainless Steel Housings
Engineering summary from PDF text extraction for 8 inch Stainless Steel Housings. Verify every value with the OEM datasheet.
Summary
Product identification
These are 8-inch side entry Stainless Steel Membrane Industrial Housings, designed for RO/NF/UF machine assembly.
Standard housing packages are available as:
- 804P-300 (300 psi)
- 804P-450 (450 psi)
- 804P-600 (600 psi)
- Customized
Key features of stainless steel housings:
- No seals are involved in side port connections.
- They do not warp or weep, unlike fiberglass.
- They are unaffected by UV rays or sunlight.
- Stainless steel is a preferred and universally accepted material for water systems.
- Capable of supporting process piping.
- During assembly, stainless housings are lighter and easier to handle than PVC and FRP housings with equivalent pressure ratings.
