Expansion Joint Product Description: An expansion joint is a flexible connector designed to absorb movements effectively caused by external factors such as thermal expansion, contraction, vibration, installation misalignment, and seismic activity, while safely containing the fluid within piping systems. It is manufactured in various types and sizes according to design conditions, including pressure, temperature, fluid type, service life, and installation environment. An expansion joint is a flexible connector used to absorb movement from thermal changes, vibration, misalignment, or seismic activity while sealing in fluid within a piping system. Types include metal expansion joints for high-temperature and high-pressure use, non-metal types for flexible, low-pressure environments, and rubber joints for effective shock and vibration absorption in HVAC, drainage, and water treatment systems. Specification: • Metal Expansion Joint: Metal Expansion Joint is a flexible connector made with metal bellows, designed to perform reliably in high-temperature and high-pressure environments. It is widely used in various industries such as power plants, petrochemical facilities, shipbuilding, and steel manufacturing. • Non-metallic Expansion Joint: Non-metallic Expansion Joint is a flexible connector made from non-metallic materials such as fabric, fiber, plastic, or rubber. It is used to absorb thermal expansion, vibration, and installation misalignments in low-temperature and low-pressure environments. Compared to metal types, it is lighter and more flexible. • Rubber Expansion Joint: Rubber Expansion Joint is a flexible connector made of rubber. Due to the elasticity of rubber, it provides excellent shock absorption and vibration reduction, and is primarily used in low to medium pressure environments. It is commonly used in HVAC systems, drainage systems, and water treatment facilities.
