2. Description
The model 75N is designed for solving the corrosion problems which
usually happen in low pressure piping systems. Our couplings are
produced in good quality reinforced nylon, injection molded by high
temperature. It features its high strength and toughness, perfect
corrosion resistance performance. They're widely used in ultra
filtration ( UF ) membrane system and other water treatment,
seawater desalination equipment.
Our flexible couplings give contractors, engineers and owners an
unmatched competitive edge cutting piping system installation time,
and making installations safer. These grooved pipe joints offers
you with innovative solutions
acrossdiverse business lines including building services, clean
water and waste water, fire protection, industrial
construction, maritime, mining, oil, gas and chemical, power
generation, as well as custom castings.
Quick joints housing materials:
Nylon, other composite, plastic material upon demands.
Bolts&Nuts:
- Type 304 stainless steel track bolts and nuts to ASTM F-593
- Type 316 stainless steel track bolts and nuts to ASTM F-593
- Type 316 stainless steel track bolts ASTM A193 B-8M with silicone
bronze heavy duty nuts to ASTM B98 C65100
Rubber Gaskets or seals:
The gasket seals is C-shaped, made of standard gasket EPDM
(ethylene propylene diene monomer) for cold water, hot water, rare
acid, oilfree air and multiple chemical product (-50~150 ).It is
not suitable for medium like petroleum
3. Applications

desalination, |
Waste water | Water treatment, waste water treatment, seawater desalination,
effluent treatment plant |
Grooved piping | Fire protection, industrial construction, maritime, mining, oil,
gas and chemical, power generation |
4. Competitive advantage
- AutoCAD is used to design products and optimize structures
Cast Process Design by by Castsoft CAD and CAE
Strict Manufacturing Process control
Quality Control Of The Casting Material
Metal Material Laboratory for test of compositional, metallographic
& mechanical property
Perfect apperance
Strict test standard compliance to UL213 and FM1920
Strict standard for sealing gaskets production and material test.
