expansion joints / galvanized rubber expansion joint for water drainage

Product description

1. All rubber expansion joints are finshed with retaining flanges, limit rod units are available on special request

2. Pressures shows are recommended"operating", test pressure is 1.5time"operating", burst pressure is 3 time "operating".

Chemical Resistant PTFE Lining Rubber Expansion Joint

Product description

An expansion joint is designed to allow deflection in the axial (compressive), lateral (shear), or angular (bending) deflections.Expansion joints can be non-metallic or metallic (often called bellows type).

Rubber Expansion joints or Rubber bellows are primarily used to absorb noise and thermal movements along with the removal of vibration between equipment such as diesel engines, cooling water pumps, condensers, chillers and their mating pipe work.

The rubber expansion joints are molded with a single arch and useful for connections that may require axial compression, axial extension, lateral deflection, angular deflection. Both ends of the joint can be deflected. Body in EPDM or NBR, flanges in galvanized steel.

Feature

1. Metal bellows to absorb large axial displacement between straight tube and support frame, and small horizontal displacement;

2. To resolve minor deviation because of piping connection and eliminate the pipeline residual stress;

3. All of our metal bellows are easy to clean and maintenance

Professional manufacturer telescopic rubber expansion joint

Product description

rubber bellow expansion joints are the best solution to isolate vibration, dampen noise and pressure surges coming from for example engines, pumps and/or turbines. Additionally, these expansion joints are suitable to compensate thermal elongation or even misalignments.

The addition of the rubber properties and Nylon-cord reinforcement provides a flexible pipe joint that is easy to install, efficient and a long service life. These compensators allow angular and lateral movement as well as axial compression and expansion.

Feature

* Small size,light weight,good elasticity,easy to install.

* It can absorb lateral,axial and angular displacement caused by pipe vibration after installation,and is not limited by pipe's non-concentric and non-parallel flange.

* When working,the structure can be reduce noise transmission and strong vibration absorption ability.

PTFE Bellows/Expansion Joint

To compensate for length changes in pipelines expansion bends, stuffing box compensators or expansion bellows are used. Bellows have proved particulaly suitable for lined pipe which may be subjected to shock and vibration. They also accomodate axial misalignment. Further advantages include simple space-saving design and speedy installation.

Typical Applications

Chemical Engineering-PTFE is employed in all cases where corrosive substances are used and where conventional materials create sealing problems. Glass apparatus is an example. In this type of equipment, PTFE is used for expansion bellows, which are designed to compensate for mechanical and thermal changes, flexible tubing, seals, glandless valves, turbine stirrers, etc.
