Threaded Screwed EPDM Expansion Joint Rubber Bellows

1.Specifications
Threaded Union Screw Flexible Rubber Expansion Joints
1) Greater movements are available
2)Absorbs vibration-noise-shock

2.Discription of threaded rubber  Joint  :

consists of the inner, enhancement layer, a rubber vulcanization molding and rubber compound model of double parallel movable joint and the metal ball. High pressure resistance, good elasticity, large displacement deformation, damping noise reduction effect is good, flexible installation, long service life, etc, can be widely used hotels, factories, residential water heating pipe system and circulating water pipes and plumbing, chemical corrosion and freezing pipes.

Its functions have small volume, small weight, good flexibility, easy installation and maintenance. It can made horizontal, axial and angular displacement when being installed.

3.Characteristic:

1) This product could primarily reduce the vibration and the noise of the piping system, completely solve the different piping problems as displace of joint, axial flex and etc.
2)According to different material requirement, product could be made as acid proof, corrosion proof to suit different medium and environments.
3) The materials are good sealing, light weighting, easy to fix and maintain, also has long-working expecting. But please keep far away from sharp metal in order to avoid breaking of the rubber body.
4) For flanges of other standards or non-standards. It is necessary to be agreed upon separately. Please specify standard of furnish diagram and relative parameter. We will manufacture accordingly. Rubber material may be selected according t your requirement.
5)Anti-corrosion: EPDM and NBR rubber can bear high temperature and can anti-corrosion.
6) Double sphere flange end rubber joint: The rubber body have two bridges. It can bear more pressure and the length is long than single sphere rubber joint.
7) The size can made as customer's drawing, we can make mould for special type.
8)They are cost effective, the total cost is low because of rubber is cheap and it have long use

4.Advantage of our rubber joint:
A.Ozone and chemical resistance
B. High temperature resistance
C. Excellent weather resistance
D. Anti-aging, anti-radiation, good flexibility, good elasticity
E. Excellent resistance of acids, aliphatic hydrocarbons
