Product Description
garden hose fire machine nakajima type storzs withs coupling Characteristic :
1. Excellent sealing: With the perfect combination of Novel-Polymer-Material body, and high-quality rubber this coupling has excellent sealing performance.
2. Excellent corrosion resistance: the advantages of new polymer material is its good corrosion resistance, especially for the pipe connection of a variety of purposes, for example the harsh environment of the seawater desalination and wastewater treatment engineering.
3. Prominent high pressure resistance, anti-fatigue: and experimental data shows that the composite material products can resist pressure up to 6.9 MPa, and it can work through 100,000 cycles of fatigue test of 5.5 MPa.
4. Light and beautiful: Compared to stainless steel products, its weight is only 50% of stainless steel,which is easy to transport. It can be made in various colors for different pipes.
5. Specification is complete: It has models of DN25, DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300 also it's in the development of more product specifications.
6. Easy to operate: It makes the operation of pipe connection extremely convenient, with special accessories and more flexibility.
7. Special attachment is complete: We provide the special attachment of a variety of materials, caliber, interfaces to help it work under various environments.
8. Wide temperature ranges: It is suitable for temperatures from -17°C to 160°C.
9. High performance-to-price ratio: We provide products with good price, and guarantee the same performance as high-cost products.
Application:
It can be used for low-pressure microfiltration, ultrafiltration, and reverse osmosis, sewage systems and other piping connections. The coupling body uses the novel polymer material that meets the standards of ASTM A351 and A743. The sealing "C" ring's material is EPDM and can work under temperature of -50°C to 150°C . Also it can be applied under chemical environment like diluted acid and non-oil air.

Changzhou Duoling Water Treatment Factory established in 1985. Our factory is located in Jiangsu Province of China, covering an area of 15, 000sqm. We mainly manufacture disc filtration system, water filters, filter cartridges, water valves, couplings, and plastic flow meters. With the modernized workshop, advanced mechanical equipment and competent staff, we provide high-quality products that have been well applied in industry, agriculture and environmental engineering. Many of our products have been exported abroad such as South-East Asia, Europe, Australia and Northern America.
Our factory establishes a system in strict accordance with ISO9001 standard. Our stainless steel couplings has patent and the material can be 304, 316L, duplex stainless steel or any other high quality special stainless steel. Our disc filters, auto backwash ceramic membranne filter, high flowrate PP pleated filter, backwash valves can fulfill different water treatment projects. Compared with traditional water filters, our disc filtetration system can save water and do excellent backwash and the weight is much lighter. It is more economical, high automatic, and space-saving.
Our factory holds the idea of "striving for excellence, customers oriented". Welcome your partnership and cooperation with us. We will provide you with the best products and the most professional service.
