How non-metallic expansion joints from Sudbury International benefit ducting systems

Ducting and piping systems are a typical applications for fabric expansion joints from Sudbury International.

Sudbury International Engineered Products Limited is a great source of cost-effective solutions for manufacturing companies, including its inventory of metallic and non-metallic expansion joints. The company offers a line of fabric expansion joints that are ideal for ducting and piping systems, in which they absorb thermal growth, isolate noise and vibration, and allow for misalignment.

Non-metallic expansion joints from Sudbury International offer a lot of capabilities and advantages that make them essential for ducting applications.

Providing stress relief and seals

Non-metallic expansion joints are flexible connectors that offer stress relief and seals in gaseous media in ducting systems. These products have been used for about half a century in numerous industries and processes, including power generation, nuclear power, pollution abatement, pulp and paper, petrochemicals, metal processing, cement, waste incineration, marine applications, and dust recovery.

Sudbury International offers joints that provide flexibility in ductwork to allow for four common situations: expansion or contraction of ducts because of temperature changes; isolation of components to reduce the effects of noise or vibration; component movement during process operations; and installation or removal of large components and erection tolerances.

Among the many advantages of using non-metallic expansion joints for ducting applications are the following:

• Large movements in a short length;
• The ability to absorb simultaneous movements easily in multiple planes;
• Only low forces required to move the joints;
• Corrosion-resistance, due to materials that can handle aggressive chemicals;
• Noise and vibration resistance;
• Simple installation;
• Low cost of replacement;
• Freedom of design; and
• Thermal breaks.

Non-metallic expansion joints have two basic forms of construction, depending on the number of layers. These forms are single-layer and multi-layer construction. Single-layer construction uses one consolidated layer, often made from elastomers or fluoroplastics and reinforcement materials. In multi-layer construction, the various plies are made of different materials that are not integrally bonded together. The various configurations include clamping, belt-type, flange-type, and flexible-element configurations.

Sudbury International supplies various styles of fabric expansion joints, including square, u-type, belt-type, round, and rectangular. A variety of material is also available.
