We are pleased to introduce ourselves as one of leading manufacturer & exporter of Rectangular Expansion Joints & Bellows in India. We are among few manufacturer in India who manufacture full range of Expansion Joints--Metallic, Non Metallic, Circular, Rectangular, Square, Fabric, Canvas, EPDM, Multilayer, etc. The material are designed as per customer pressure & temperature rating & application. The end fittings are tailor made as per customer requirements and design.
At Unick Control System, we take pride in manufacturing high-quality expansion bellows, both rubber and metallic, meticulously designed to meet our clients' exact specifications. Our expansion bellows are engineered to absorb thermal expansion, vibration, and mechanical stresses, ensuring enhanced performance and durability in a wide range of industrial applications, including power plants, chemical industries, and HVAC systems. Using advanced materials and cutting-edge technology, we deliver products that offer exceptional flexibility, pressure resistance, and longevity. Whether itâ??s rubber bellows for superior elasticity or metallic bellows for high-temperature and pressure environments, we work closely with our clients to provide customized solutions that meet their operational needs and ensure seamless functionality.
Description: Fabric expansion joints are extremely flexible and can be made from a variety of special woven fabrics coated or laminated with selected elastomers or fluoropolymers. Fabric expansion joints are easy to customize to suit existing operating conditions and are easy to transport and install. In comparison to metallic expansion joints fabric offers almost unlimited flexibility, giving the pipe work designer more options. The type of fabric expansion joints are Round fabric expansion joint and Rectangular fabric expansion joint. Featureï¼? 1.Multidimensional direction can be compensated. Various forms, large compensation and long service life; 2.Effective compensation or elimination of installation errors; 3.Low stiffness and small elastic reaction; 4.High temperature range and good corrosion resistance; 5.It can effectively isolate vibration and reduce noise.

Expansion joint Expansion joint can also be called pipe expansion joint, compensator, expansion. Expansion joint is divided into: corrugated expansion joint, sleeve expansion joint, square natural compensation expansion joint and other major types, 1. Compensation for expansion deformation caused by heating of absorption pipeline in axial, lateral and angular directions. 2. Absorb equipment vibration to reduce the influence of equipment vibration on pipeline. 3. The amount of deformation of pipelines by absorbing earthquake and subsidence. Because of the heat expansion and cold contraction of the pipe, so for the pipe, it is necessary to produce the stress and push tension of the pipe wall; The stress on the wall of the pipe affects the strength of the pipe, and the push and pull force increases. The fixed bracket of the pipe should be made large to withstand the push and pull force generated by the pipe expansion. Therefore, the variable opening method compensated by the ductile iron pipe mechanical joint fittings is used to reduce the stress and thrust of the pipe wall. The expansion joint is mainly used to compensate the expansion deformation caused by the temperature change of the pipeline, and also to compensate the length of the pipeline due to the installation and adjustment. It is mainly divided into three structural forms: wholesale elbow expansion joint, bellows expansion joint and casing expansion joint.
