Line Stop Devices and Pipe Closing Plugs

A version with a special sealing plug and an opening/passage allowing for the drainage of the medium (or, as the case may be, other functions like de-aeration, gas drainage, filling with inert gas and the like) from the closed pipeline behind the closing balloon and with a locking system. The locking system (a locking nut and fork) makes it possible for safe and gas-tight but easy and promptly fixing of the closing balloon inside the ballooning adapting piece. This structural design significantly reduces risks during work with flammable gases or other flammable media handling in explosion risks areas. In case of explosion of an explosive mixture in the pipeline, the balloon adapting pieces will remain gas-tight closed and the medium will not leak to the workplace. Working part – for properties and description following the sheet 2.2 –3. Loading part – a fixed loading tube with a sealing plug, an opening/passage ended with a ball valve and a hose extension diameter 20 mm, integrated pressure gauge with a hose extensions diameter 10 mm, identification plate. This type of the closing balloon in this versions is made of materials that must not be exposed to any organic solvents, oil products, fats, acids, caustics and their vapours. The version made be modified based on customer requirements (following the sheet 2.2-1).
