Rubber soft joints are made without recycled rubber, using natural and chlorinated butyl rubber compounds. They are suitable for passing through water, steam, weak acids and alkalis, eliminating the sweating phenomenon of the spheres, extending the service life, and have a product life cycle of 5-10 years. Both the rubber raw materials and accessories are of qualified quality, with spheres free of odors and resistance to aging five times that of engineering rubber joint spheres. They are formed by an automatic molding machine using a solid winding method, withstand high pressure, and have a test pressure of 50 kg, with three times the tensile strength of hand-formed joints. The rubber soft joints utilize the elasticity, weather resistance, high airtightness, resistance to chemical corrosion, and radiation resistance of rubber. After being compounded with high-strength, cold and heat stable polyester cord, they are vulcanized under high pressure using high-precision molds, resulting in a smooth and fine rubber surface, with quality that is evident. The inner diameter is standardized, covering basic engineering fields such as chemicals, construction, water supply, drainage, oil, food, machinery, refrigeration, sanitation, plumbing, fire protection, environmental protection, coastal, and power, particularly suitable for pipelines with significant vibration and frequent changes in temperature.
Reduce fatigue coefficient
Due to the inherent properties of natural and synthetic elastomers, and the steel-rubber interface at the joints and mating flanges, they will not fatigue crack or become brittle, and will not generate any electrolytic action.
Excellent wear and corrosion resistance for all industrial applications
Utilize a variety of natural, synthetic, and specialty elastomers and fabrics. Processed and combined materials can meet a wide range of actual pressure/temperature operating conditions, corrosion, erosion, wear, and abrasion. Refer to the technical specifications and applicable piping for suitable media and industries.
Compact face-to-face size, yet absorbs larger movements
The rubber expansion joint features a compact face-to-face length and offers excellent movement capabilities in axial compression, axial extension, lateral deflection, as well as rotation and twist directions.
Rubber
Inherent flexibility reduces spring stiffness; the inherent flexibility of the rubber expansion joint allows nearly limitless deflection to recover from imposed motion, requiring relatively low force and thus preventing damage to the power equipment.
No installation gaskets required
Flanged sulfur rubber and woven fabric integrated with hoses do not include flexible expansion joints, so gaskets are generally not required for most applications. Please check the assembly instructions before installation.
Lightweight
Rubber expansion joints are lightweight, which helps reduce installation labor costs.
Minimize heat loss
Rubber expansion joints reduce heat loss and provide long-term maintenance-free service.
