Global original equipment manufacturer of rubber and steel expansion joints
As a leading distributer of rubber and steel expansion joints, we supply all sectors, such as the machine construction, motor production and industrial equipment manufacture industries, whilst always taking into account all applicable standards such as the below:
Tested resistance to extreme heat and fire
A number of EP&S expansion joints are often used for industrial applications in incredibly heat-intensive environments and are therefore tested for fire resistance in accordance with DIN EN ISO 15540/41. As part of this flame-resistance testing, the expansion joints are exposed to a temperature of 800°C with an internal pressure of 10 bar for a period of 30 minutes and must continue to function correctly during this time. Following flame impingement of the expansion joint, the joint must withstand a burst pressure test of at least 15 bar.
Among other tests, EP&S rubber expansion joints must regularly undergo and satisfy hydraulic pressure impulse tests with a wide range of frequencies based on EN ISO 6803 as well as successfully overcome endurance tests with 10 million lateral load changes in accordance with the DNV GL rules, standards and guidelines.
The most flexible range of potential applications – particularly in hydraulic control and drive systems
EP&S offers outstanding product quality in the field of flexible pipe connections around the world. Thanks to their special NBR lining, which is suitable for oil and oil-containing media as well as compressed air and coolant with added antifreeze protection, our EP&S expansion joints can easily be used in a wide variety of industrial applications such as control and drive systems.
Extreme resistance to aggressive media
EP&S offers solutions for any extreme application. Special expansion joints with EPDM linings are especially ideal for industrial applications involving acids and bases. For applications in which particularly aggressive media are used and EPDM is no longer suitable, EP&S offers specially developed expansion joints made from PTFE; these have universal chemical resistance to almost all chemicals and solvents. Its bellows are moulded from highly compressed virgin PTFE or are lined as rubber expansion joints with a seamless PTFE liner and self-sealing flange ends. These expansion joints are used most frequently in the chemicals industry, the process engineering sector, the pharmaceuticals industry and the food and beverage industry, for example.
