Naigai Pressure PF Type (large diameter ) E-P Joint
Made in Japan
Manufacturer: Naigai Rubber Industry Co.,Ltd
Model: Pressure PF Type (large diameter )
Features
-
Anti-vibration effect
EP JOINT, which has a small spring constant, is effective in preventing vibration.
-
Displacement absorption
EP JOINT, which has excellent elasticity and shape recovery properties, protects piping by absorbing displacements such as eccentricity, declination, expansion and contraction.
-
Easy construction
EP JOINT is lightweight and compact, does not require packing, and has a loose flange, making it easy to install.
-
Combined effect
By using EP JOINT, you can obtain vibration isolation effect and displacement absorption property at the same time.
Operating pressure: 0.29MPa (3kgf/cm²) or lower
Negative pressure: -0.01MPa (-0.1kg/ cm²) or higher
Operating temperature: -30°C to +100°C (Cooling and heating water)
• Before use, check that maximum working pressure and maximum working temperature are within operational ranges.
Standard Dimensions and Allowable Displacements
- Weights with SS400 or JIS10K flanges (standard) mounted are indicated.
- Dimension allowances on installation are included in allowable displacements.
(Allowable displacement = Dimension allowances on installation + Displacement under operation)
Product features
- Pressure type PTFE inner surface coating type.
- Excellent chemical resistance employing PTFE (polyethylene tetrafluoride) on areas in contact with liquid (internal surface).
- Increased resistance to external shocks due to integration of structure with durable, strong rubber.
Product applications
- Piping for corrosive chemicals in chemical plants.
- Piping for transporting oils, solvents and food.
- Piping for pure water in IC plants.
- For isolation of vibrations in corrosion-proof pumps.
- Piping for water heaters and swimming pool water circulatory systems.
