This kind of expansion joint is used as a flexible connecting element between a wall and the tubes which pass through it.
It is generally applicable to:
- The roof, bottom and side walls of boilers;
- Naval equipment
- Fire prevention facilities
Especially when used in boilers, it constitutes an advantageous alternative to the metal expansion joints typically used.
It is also a particularly suitable solution in case of replacement and/or repair because it can be supplied open to be assembled in place, thus avoiding expensive cutting and restoring costs of the high pressure boiler tubes to which they are connected.
BBV Tech has a long experience in producing this typically “custom” product, made in different shapes, sizes and layers, according to customer specifications.
