Membrane housing belongs to the terminology of composite materials. Usually there are glass fiber reinforced plastic membrane shell, stainless steel membrane shell, ceramic membrane shell, the models are various, and the models are different according to different functions.
4040 membrane housing is divided into two types: seamed and seamless, and is made of SUS304 stainless steel. Both ends are sealed with ABS head and silicone O-ring, with high sealing performance and long service life.

Reverse osmosis and nanofiltration membrane membrane shells generally use glass fiber reinforced plastic or stainless steel, because they have to withstand greater pressure. Ultrafiltration membrane membrane shell generally uses UPVC or ABS, because the operating pressure of ultrafiltration is generally low (generally less than 0.3Mpa). UPVC pipes can be used to make small ion exchange beds in addition to membrane shells in water treatment equipment. Common materials are stainless steel


4inch membrane housing has 1-core, 2-core, 3-core, 4-core and other series.
The membrane shell tube is divided into two types: seamed tube and seamless tube: The seam tube is automatically welded and formed, and the welding is uniform and flat. The internal and external surfaces are mirror treated. The pressure test is carried out before leaving the factory, and the pressure is up to 16KG The seamless pipe is directly pulled out with the section blank, the wall thickness is uniform, and it is not easy to leak. The internal and external surfaces are subject to mirror treatment. The pressure test is carried out before leaving the factory, and the pressure is up to 25KG.
There are two connection modes of water inlet and outlet: side inlet and end outlet; The specifications are 3/4" x 1/2" and 1/2" x 1/2".
Head materials include ABS and stainless steel.

Membrane housing classification/application The membrane shell is divided into eight-inch membrane shell (8040) and four-inch
membrane shell (4040). The membrane shell has one core, two cores, three cores...seven cores. (8040,,8080,80120...80280) Commonly
used membrane shells are mainly used in seawater desalination and sewage treatment
