Grooved Pipe Fittings for Fire Fighting System

What is the role of pipeline couplings in the fire protection industry?

Couplings: a small part with a crucial role in fire protection
Grooved couplings play a critical role in the fire protection industry, as most sprinkler pipe connections require rigid joints. However, in certain instances, such as seismic design requirements, greater flexibility is needed to prevent damage during earthquakes. Flexible couplings are the solution in such cases.
Qualified fire protection system planning is necessary to ensure the safety of fire protection systems and must be conducted in accordance with local regulations. Determining the Seismic Design Category (SDC) of a building is essential to determine whether special equipment is necessary for seismic design.

HT Casting offers a wide range of pipe fittings to meet your needs

Both rigid grooved couplings and fittings are available in stock and online.
For custom-designed flexible couplings, please contact us for special orders.
