Stainless Steel Membrane Housing
4040 membrane housing is divided into two types: seamed and seamless, made of SUS304 stainless steel. Both ends are sealed with ABS heads and silicone O-rings, with high sealing performance and long service life.
8040 membrane housing: divided into two types: ferrule and end cover, made of SUS304 seamless stainless steel pipe, with good sealing performance, high-pressure resistance, no aging, easy installation and cleaning of membrane, working pressure (Mpa): 4.0. The inlet and outlet of the membrane shell can be end inlet (outlet) or side inlet (outlet) according to customer requirements.
Features
- The housing is made of 304 stainless steel tubes, and the membrane housing is polished inside and outside. Both ends are sealed with ABS heads and silicone O-rings, with high sealing performance and long service life.
- Water inlet method: water inlet at both ends (Type A), water inlet on both sides (Type B).
- Structure: standard spare parts, easy and quick to disassemble.
- Sealing: pressure-resistant test.
