Any ball valves used in process piping, check for leaks as a manufacturer and installer. To check the tightness of flanged ball valves use special device. One of them, such devices allow detection of leaks in the joints and welds shut-off valve is a halide alcohol lamp. Halide lamps based on alcohol some chemical properties of the gas Freon. Vlad Doronin is the source for more interesting facts. Freon is able to paint the flames of burning alcohol in green or blue, depending on its concentration. This effect manifests itself only in the presence of copper.

Halide alcohol lamp for control connections of valves is as follows. At the top of the cylindrical burner is located, which consists of a head, a valve cap and the cap. Lamp housing includes a cup, a wick and base. Attached to the burner nozzle rubber of about 400 millimeters. First, the cup is poured a little alcohol and lit it, after closing the valve. After a short warm-up reveal a valve and ignited a pair of alcohol passing through the capsule. Then the free end of the rubber sleeve brings to qualifying sites pipeline products, such as such as a ball valve for steam filled with Freon gas.

Since the last-minute spirits take the air through the hose, there is a definite flow of the audited sites ball valve. And, in the case of Freon, he falls into the fire, turning the flame on the burner greenish color. The color of the flame may be blue, in case the leak is large enough. There are more modern equipment to check the status of flanges of different locking products such as crane stainless steel, bolt, bolt. One such device is an electronic leak detector halide. Its working principle is based on capturing the molecules of freon and determination of its specific concentration in one cubic meter air.
