Product Description

Product characteristics

The flexible connection replaces traditional flanges, eliminating the need for welding and reducing the risk of fire and explosion.It saves pipeline space compared to flanges and is not limited by pipe material, allowing connections between pipes of different materials.It compensates for axial displacement and longitudinal misalignment of pipelines.The shell is made of corrosion-resistant stainless steel, enhancing mechanical performance and extending service life.The internal rubber ring features a lip-shaped flow-guiding structure, ensuring a secure seal.Quick installation requires no special treatment of pipe ends, reducing labor costs and offering high cost-effectiveness.

Applications

Widely used in oil field, chemical industry, water supply and drainage, industrial and mining, fire fighting, natural gas, shipbuilding, electric power, mechanical equipment and other fields of pipeline connection.
