FM APPROVED PIPES AND FITTINGS

TANGENT offers a complete PE 100 SDR 11 FM approved piping system for 12 bars (175 psi) underground fire fighting pipelines (”PE pipes and fittings for underground fire protection equipment according“ to FM 1613).

FM Global approves industrial products and services, moreover their activities help to avoid material damages. Underground installed PE 100 fire fighting pipelines that have to accomplish elevated requirements are one of those activities.

Manufacturers of FM approved products are allowed to place “FM approved" labels onto their products. The obvious advantage is the higher safety of the system. Studies showed that FM approved products which were installed according to FM Global installation guidelines reduce the risk of material damages.

HYDROSTATIC PRESSURE TESTINGTANGENTGROUP

Associate Partners


Hydrostatic Pressure Testing:• Subsequent to pipe installation, pressure testing needs be conducted on the entire network.• The pipe that has been joined, needs to be filled with water, carefully bleeding off any trapped air.

The pipe is subjected to a hydrostatic test pressure that is 1.5 times the system design pressure for a maximum of 3 hours. During this time, water is added periodicallyto maintain the test pressure; this compensates for the initial stretching of the pipe. The line pressure tightness is determined by visual observation; therefore, it is not necessary to measure the make-up water.

Every fused joint must be examined; any leakage must be repaired and then retested.
