Leakage Test Working temperature
Double visual inspection of all pipe connections EPDM Black Water -30°C to 120°C
Testing of all thread connections under 0.8 bar water pressure FKM Green High-temperature system -20°C to 200 ° CHNBR yellow oil and Gas -20-100 ℃
Minimum And Maximum Working Pressure
We did a pressure test of 40 Bar of press fittings from
15 to 54 for a month without leaking.
We recommend using working pressure as follows
OD15-22mm -8 to 40 Bar
OD28-35mm -8 to 25 Bar
