The limit rods rubber expansion joints are emloyed to limit the axial compression or expansion, which allow the expansion joint to move over a range according to where the nut stops are placed along the rods. Limit rods are used to prevent bellows over-extension while restraining the full pressure thrust of the system.

Specifications of limit rods rubber expansion joints:
Size DN25-DN3600
Flange DIN/BS/ANSI/JIS/UNI and so on
Type Single sphere or arch/Double spheres or arch

Main parts and materials of limit rods rubber expansion joints:
Outer & Inner Rubber EPDM,NR,NBR,Neoprene
Strengthen Ring Steel wire ring
Frame Nylon polyester fabric
Flange Carbon steel/Stainless steel

Applications of limit rods rubber expansion joints:
Liwei limit rod rubber expansion joint are widely used in the industries such as petroleum, chemical industry, papermaking, construction, water supply and sewerage works.
Defending piping and equipments systems from stress or motion.

Applicable media: Air, compressed air, water, sea water, oil, acid, alkali, almost all kinds of medium.
