Fire Resistance Testing Apparatus For Grooved Couplings And Fittings

What is the Fire Resistance Testing Apparatus For Grooved Couplings And Fittings？

ZONSKY Fire Resistance Testing Apparatus for Grooved Couplings and Fittings is used to assess the fire endurance and structural integrity of grooved piping components under high-temperature conditions. This equipment exposes couplings and fittings to controlled fire scenarios, measuring their ability to maintain mechanical performance and prevent leakage under thermal stress. 

Compliance：It meets the standard requirements of Section 7.14 of DIN 14521-1987、 NF S61-820-1/IN12010、NF S61-820-2/IN12010 "Automatic Sprinkler System—Part 11: Grooved Couplings and Fittings".
