1. Metal Expansion Joint (HS CODE: 8307.10.0000)
Metal expansion joints are compensating elements for thermal expansion and relative movement in pipelines, containers and machines. They consist of one or more metal bellows, connectors at both ends, and tie rods that depend on the application. They are differentiated according to the three basic types of movement: axial, angular and lateral expansion joints. Expansion joints have usage in various sectors, like energy productions, paper industry, chemical industry, water treatment, oil and gas. Everywhere where exist pipelines and occurs thermal movements or vibration, then expansion joints can be used.
2. Rubber Expansion Joint (HS CODE: 4016.99.9000)
As specifically engineered products that are inserted in a rigid piping system, the Rubber Expansion Joints will absorb movement, improve thermal stability, relieve system strain due to thermal change, load stress, pumping surges, wear of settling, and reduce mechanical noise.
