Axial Expansion Joints For Earthquake
Shrouded Single-Direction Seismic Absorber DK-S3000
- ▶ Where the piping needs a very large movement range, this shrouded single-direction seismic absorber is used. It combines multiple bellows, is unaffected by elongation from internal pressure, absorbs large displacements and gives the piping the best protection
- ▶ In this externally pressurized flexible joint, the bellows are designed to carry external pressure and have two or more plies. A heavy outer sleeve fully encloses the bellows to protect them from external damage, and an inner sleeve shields them from the water flow
- ▶ The inner and outer sleeves keep the joint on its centerline without deviation under tension or compression
- ▶ For important lines such as water supply and drainage, HVAC and fire protection
Hinged Seismic Absorber DK-S5000
- ▶ Seismic design of horizontal pipes and risers for water supply, drainage and fire protection inside buildings
- ▶ Handles large angular displacement of a single line in a confined space
- ▶ A single bellows designed to allow angular rotation in one plane. A pair of pins passes through hinge plates attached to the ends of the expansion joint, absorbing large angular displacement
- ▶ The design restrains the pressure thrust and external forces on the expansion joint. Hinged seismic absorbers work best when used in sets of two or three in a piping system
PRODUCT DESCRIPTION
Where the piping needs a very large movement range, this shrouded single-direction seismic absorber is used. It combines multiple Bellows, is unaffected by elongation from internal pressure, absorbs large displacements and gives the piping the best protection. For important lines such as water supply and drainage, HVAC and fire protection; for the seismic design of horizontal pipes and risers for water supply, drainage and fire protection inside buildings; and for large angular displacement of a single line in a confined space.
