Details Overview
Food-grade rubber expansion joints are made of food-grade silicone rubber. They can transport drinking water, juice, and other edible products. They are highly elastic pipe fittings with high airtightness, media resistance, and weather resistance.
It utilizes the advantages of rubber, such as high elasticity, high airtightness, media resistance, weather resistance and radiation resistance, to reduce pipeline vibration and noise, and can also compensate for thermal expansion and contraction caused by temperature changes.
Advantages
- Outstanding Pressure Resistance
It boasts excellent pressure resistance, featuring a spherical structure that provides superior stability against internal pressure, and is made with a strong, specially reinforced nylon. Runtaida flexible connectors offer outstanding pressure resistance.
- Good Vibration-Noise-Shock Absorption
Runtaida single-ball flexible rubber joints are designed to reduce the inherent vibration, noise, and movement of piping systems. Runtaida joint installation allows isolated equipment to move freely, eliminating the vibration and repulsion noise prevalent in metal-type joints.
- Compensation for Greater Elongation, Compression, Lateral, and Angular Movements
Equipment such as pumps, coolers, cooling towers, compressors, and piping systems are susceptible to wear, load stress, and misalignment during base block installation. Runtaida flexible connectors are designed to withstand lateral, torsional, and angular movements to prevent damage, thus eliminating costly downtime in plant operations.
