Induchem Group are the Irish distributor for the full range of Protectoseal products.
Protectoseal has been an industry pioneer and leading manufacturer of quality products that conserve and control volatile emissions and protect low pressure storage tanks, vessels and processes from fire and explosion for over 85 years.
Protectoseal’s integrated line of pressure and vacuum relief vents, flame/detonation arresters and related vapor control devices are used across a wide array of process industries
500 PPM PRESSURE RELIEF VENTS
PIN-TECH® Pressure Vents are designed and tested to address concerns about the leakage of fugitive emissions prior to set point.
Series No. 56000, Bubble-Tight <500 ppm Pressure Relief Vents are designed
and tested to address concerns about the leakage of fugitive emissions prior
to set point, and parts per million (ppm) emission rates.
Protectoseal’s PIN-TECH vents are mounted to the vapor space flange connection of a storage tank or vessel. The vents utilize a unique technology that employs a buckling pin to hold the vent piston closed (Fig. 1) with zero leakage up to the relief set point. The pin is an accurately machined, straight metal rod. It is configured to precisely sense transmitted axial forces that are generated as a result of tank pressure. The force required to buckle the pin is governed by Euler’s Law and is a function of the pin’s metallurgy, length and diameter. An exact buckling force can be determined for any specific pin configuration. When the pressure in the tank reaches the vent set point, the axial force is sufficient to buckle the pin and the vent sealing piston is allowed to move to its full open, relieving position (Fig. 2). The pin buckles completely and instantaneously.
