Stainless steel shell RO membrane

Stainless steel shell RO membrane
Stainless steel RO putamina overview
An overview，
Stainless steel pressure vessel shell is also called the membrane， is reverse osmosis， sodium filtration， ultrafiltration device such as accessory products， the shell adopts 304 stainless steel tube manufacture or wire winding FRP， inside and outside membrane shell polishing.
Second， the main technical features
 
 


Low pressure: 2.0 ~ 2.5 MPa
Low water: water， water on both sides at both ends
Low structure: standard parts， and convenient disassembly
Low sealing: after pressure test
Low on both ends of the organizational structure: clamp， the card type， the inner spring type.
Mainly depends on the designer’s requirements， the arrangement of membrane and the requirements of different， according to the import and export of different angles are divided into: 0 degrees， 90 degrees， 180 degrees and three， from a purely pressure theory， side water better， but increased the probability of pressure vessel water leak.
2.8 -inch membrane for water flow and pressure is much bigger than 4 inches of RO membrane， if a port on the membrane shells open two mouth， can make the end face of the pressure resistance is reduced， at the same time also increased a lot of trouble in installation
3.Mainly concentrated water flow problem， because single membrane element to the maximum design was 16%， the recovery of water in order to improve the utilization of the water， so the more to complete the film series， due to 4 inches of RO membrane pressure drop to more than 8 inches of membrane pressure drop， so its serial number cannot too much， the specific serial number also depends on water conditions and design parameters， then consider the selection of high-pressure pump.
Supply stainless steel main specifications are 4 inches of RO membrane shells and eight inches， reverse osmosis equipment parts， material quality SUS304 or SUS316L， end cover， membrane tube flange seal， silicone type o sealing ring， sealing good， pressure level is higher than the clamp， surface mirror polishing， beautiful appearance.Widely used in all kinds of water treatment engineering， pharmaceutical， electronics， chemical industry， etc.
8 "series of stainless steel membrane shells
Inside and outside are all made of stainless steel， membrane shell polishing
Method: the water at both ends (type A)， on both sides of the water into the water (type B)
Structure: standard parts， convenient disassembly
Seal: after water pressure test
Both ends of organization structure: flange， end plate
4 "stainless steel membrane shell series
Adopt the SUS304 stainless steel tube， slit membrane shells and seamless membrane shells
Head: enhanced ABS made from imported from Japan， high strength and pressure resistance
Method: the water at both ends (type A)， on both sides of the water into the water (type B)
Shell and head connection: quick open and clamp
Structure: scientific and reasonable， quick and convenient installation， withstand voltage test
A variety of accessories are made by our factory production， to ensure quality.
1. 4 "stainless steel membrane shell core 1， 2 core loading， three core and four core etc.
2. The membrane shell and tube is divided into has two kinds of seam pipe， seamless tube.
The seam automatic welding work involved forming， weld uniform， smooth， both inside and outside surface mirror processing. Before delivery to withstand voltage test， the pressure for 16 kg;
Seamless tube pull with forging stock directly， uniform wall thickness， not easy to leak， do mirror processing， internal and external surface to withstand voltage test before delivery， pressure up to 25 kg.
3. In and out of the gate connection with side in side out， side in side out two;Specifications have 6 x4 points and 4 x4 points two kinds.
4. The head material with ABS， stainless steel 304.
4 "stainless steel membrane shell
Product features:
1. The shell material: stainless steel 304 or 316 l， inside and outside membrane shell polishing
2. Head: ABS head， stainless steel head
3. Level 4 membranes can be put on
4 points， which has two kinds of seam membrane shells and seamless shells
5. Water: both ends (type A)， on both sides of the water intake (type B)
6. Shell and head connection: flange， clamp
7. Structure: scientific and reasonable， arrangement of quick and convenient， the withstand voltage test
