Made in Japan
Manufacturer: Naigai Rubber Industry Co.,Ltd
Model: SP type

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: 1.96MPa (20kgf/cm²) or lower
Negative pressure: -0.086MPa (-0.88kg/ cm²) or higher
Operating temperature: -20°C to +80°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 JIS20K flanges mounted are indicated.
•OJIS10K type flange is also available.
•Dimension allowances on installation are included in allowable displacements.
(Allowable displacement = Dimension allowances on installation
+ Displacement under operation)
•Sealing thickness is t=7 for 100A. Although thinner than for 80A or less, there are no problems with performance and durability.
