The Next Generation in LPG Unloading Hoses – Life Guard™ Safety Hoses are PESO Approved self-closing unloading hoses are used extensively in India and are mandated by the Department of Petroleum & Explosives Safety Organization, particularly for Autogas Dispensing Station Usages. In fact leading companies like Indian Oil, Total Oil etc use these hoses for their bulk installations, including Bottling Plants as well. There are more than 3,000 Life Guard Safety hoses in operation. Life Guard Safety hoses are in operations at various ALDS, Bottling Plants of Indian Oil, Hindustan Petroleum, Total Oil, SHV Energy, Aegis Logistics, Reliance Industries etc.
The Life Guard™ Safety hose is designed to increase the safety of the hose and facility, by incorporating protection against the unintended pull-away of tank trucks, railcars, barges and ships. Utilizing an Engineered Compression Spring system with two non-return valves installed within each fitting that separates under a controlled condition, it prevents product loss in the event of an emergency separation. Valve plungers or flappers installed at both ends of the hose, accomplish closure. During normal operation they are kept open by a compression spring incorporated within the hose bore. This compression spring provides thrust in the direction of both ends of the hose, holding the valves open. Should this thrust be eliminated due to coupling ejection, hose stretching or hose separation, the valves are released and instantly seat, stopping flow in both directions.
Life Guard™ Safety hose has a safety device built into the hose fitting and that is internal to a typical industrial hose that will shut off the flow of product transferred in both directions in the event of a hose coupling ejection, hose stretching to an unsafe condition, and hose separation minimizing the release of gas or liquid being transferred. Life Guard™ Safety hose is a transfer hose assembly that includes a hose with couplings on each end and a spring routed through the hose connecting a plunger, wedge, or flapper in each coupling. The spring provides a force in the direction of both ends of the hose, holding the shut off device open. Should the force be eliminated due to coupling ejection, hose stretching, or hose separation, the shut off devices are released and seat, stopping flow in both directions.
Design Pressure and Hose Standard:
- The hoses are designed to operate at a working pressure of at least 50 Bars and burst pressure of the same is well in excess of 100 bars.
- All Hoses are designed to meet and confirm to requirements of BSEN-1762.
Certifications:
All Hose Assemblies are PESO Approved and unique serial numbered, Third Party Inspected and certified to meet requirements of standard BSEN1762 with the Third Party Inspection Agency (TPIA) witnessing and certifying Pressure testing of the hoses at a Proof Pressure of 50 bars (725 PSI).
