Product Description

The flexible threaded expansion joint features internal threaded couplings at both ends for connection.It is suitable for use in central air conditioning fan coils,and its increased length ensures excellent sound insulation effect.

NO	Name	Material
1	Inner/outer rubber	NR,NBR,EPDM,FKM,PTEF,IIR,CR
2	Strengthen ring	Nylon with rubber
3	Fabric	Nylon
4	Union	Stainless steel,Malleable Iron

Performance characteristics of flexible threaded expansion joint:

 

1. Reduce the noise caused by pipeline pump vibration and have strong damping capacity.

2. Convenient installation and operation, simple and flexible.

3. It is an internal seamless high-pressure rubber joint made of rubber soft joint, which can effectively prevent the corrosion of high temperature resistant, acid and alkali resistant and corrosive medium in oil resistant pipeline to the inner wall of rubber soft joint and improve the service life.

4. After installation, it can absorb the lateral, axial and angular displacement caused by pipeline vibration and is not limited by the imbalance between the pipeline and the neutral flange.
