Product Description

4 inch double flange RF stainless steel material connection rubber joints

Specifications.

Rubber Flexible Joints
1-Connection: Flanged
2-Material: Flexible Rubber
3-Absorb vibration/shock/noise
4-DN25-3000

Brief description of rubber flexible joints:

The rubber flexible joints are designed for piping systems to absorb pipe movements, relieve stress, reduce system noise/vibration, compensate for misalignment/offset and to protect rotating mechanical equipment against start-up surge forces:

Detailed description of rubber flexible joints:

1- have superior capability in resistance of acid, alkali, oil, and electrolytic

2- become one of the alternatives of stainless steel and been successfully installed in tough work condition

3- suitable madia: chemical/petrochemical, marine, power generation, pulp/paper, steel mills and sater/wastewater treatment.

4-sturctuer: less length, the supply range is from 25mm to 3000mm

5-pressure can be 1.0MPa/1.6MPa/2.5MPa, which is always used where low cost or space limitation control.

More features and benefits:

1, Versatile hand-built construction. Made in China
2, Absorbs directional movement
3, Absorbs vibration, noise and shock
4, Compensates for misalignment
5, Wide flowing arch design
6, Virtually eliminates sediment buildup
7, Economical fully molded construction
8, High vacuum rating (up to 30" Hg) can be supplied for certain sizes
9, Special grooved flange ring design, prevent rubber end pull out
10, Solid galvanized steel floating flanges speed the installation time
11, High tensile aircraft cable is embedded in the raised face rubber ends to prevent pull out and avoids the sharp cutting edge of solid steel rings
12, No gaskets required; integrally rubber flanged design, no gaskets required, DIN PN10/16 drilling standard, other flange drilling available, including ANSI 150lb/300 lb, BS, and JIs
