Selecting the right fabric expansion joint material for your system is important towards ensuring reliable operation PK Engineering is known for being the first in Fluoropolymer capabilities by manufacturing the highest quality materials and providing the optimal solutions both technically and economically.
Expansion Bellows are used in piping systems to absorb thermal expansion or terminal movement where the use of expansion loops is undesirable or impractical.
Flexible bellows also known as expansion joints are flexible elements that absorb movements in the pipe system. These movements can they absorb are defined by Axial. Lateral, Angular and Universal movements. The flexible bellows can be designed to absorb one of these movements.
Flexible bellows are designed and manufactured by PK Engineering in all sizes from DN 25 to DN12000 in all materials.
Axial movement is a movement of the flexible bellows in the direction of the longitudinal axis.
Lateral movement is a movement perpendicular to the bellows longitudinal axis. It is shearing movement of the bellows with one end offset from the other, usually with the ends of the bellows remaining parallel to each other.
Angular movement is the rotation of the bellows longitudinal axis at one end relative to the other, the axis of rotation is taken an exactly the midpoint of the bellow and perpendicular to the longitudinal axis.
It could be designed and built to absorb applied axial , lateral and angular movements. Simultaneously such units usually require a lot of flexibility to absorb significant amounts of movements in combination.
It is important that the designer of flexible bellows is fully informed of all the movements to that the expansion joint will encounter . our experts are very much keen in these aspects in manufacturing expansion joints bellows.
