Advance Rubber Technology is pioneer in Rubber Expansion Bellows. Advance Expansion Bellows are designed to take care of reactional forces like Thermal Expansion, Contraction, vibrations etc, which otherwise break pipelines. These Rubber Expansion Joints are made up of Neoprene, EPDM, Silicone, Viton and also in Natural Rubber etc, Advance Expansion Bellows are reinforced with specially treated Nylon, Rayon, Glass Fiber, Fiber, Steel Cord etc, by taking care of the designing for perfect balance between movements of Axial, Radial, Torsion and Angular and pressure bearing capacity. Advance Expansion Bellows are available in sizes ranging from 1" NB to 72" NB with hydro testing up to 24-bar pressure. These bellows are either integrated flange (metallic flanges are bonded with rubber) or split back-up flanges, and are made strictly as per the customer's design, drawing and specification.

Advance Expansion Joints are designed to alleviate stresses caused by thermal expansion and contraction in piping systems, noise and vibration. Their flexibility permits connecting misaligned piping resulting from worn parts, foundations settling and operation of system and mechanical equipment. Advance Expansion Joints offer many user benefits over conventional metal connectors. They are non-corrosive, do not require gaskets, will not fatigue, requires small space, permit axial, lateral and angular movement, shock resistant, do not become brittle and eliminate electrolytic action.
