The document is from LifeGuard Tech, a company that manufactures safety hoses for transferring compressed gases and cryogenic liquids. It describes their LifeGuard hose system, which uses internal valves that automatically close if the hose separates, preventing the hazardous release of gases or liquids. The document discusses the advantages of different types of hoses for various applications, such as using metal hoses for cryogenics and static applications due to their zero permeation, or PTFE/Teflon hoses for high velocity flows. It also provides product codes and specifications for their high pressure safety hoses with Teflon and Tefzel linings.

HYDROGEN HOSES | CRYOGENIC LIQUID CYLINDER HOSES | METAL PIGTAILS | LIFEGUARD COMPRESSED GAS HOSES | CARBON DIOXIDE BULK LIQUID TRANSFER HOSES WHAT IS LIFEGUARDTM ? A Flexible “Safety System” for use in the transfer of high pressure gases and liquids. Protect against the hazardous effects of high pressure hose rupture, pull-apart and failure. The LifeGuardtm design utilizes the unique, patent pending design that eliminates the potential for disaster through the use of an internal compression spring device connected to specially designed, normally unseated valves located on each end of the spring. In the event of hose separation, stretching to the point of an unsafe condition or coupling-to hose separation, the valves are released and instantly seat stopping the flow in both directions. APPLICATION: For certain applications, customers choose a metal “bellows-type” pigtail which provides an all welded, zero permeation and flexible alternative to pipe and tubing, even at cryogenic temperatures. The metal lined pigtail is reinforced with two layers of type 304 stainless steel braid (Monel® braid is optional) and is designed to provide maximum flexibility. In cases where adiabatic compression in PTFE is a concern, LifeGuard Metallic Pigtails are an excellent solution. CONSTRUCTION: All LifeGuard convoluted stainless steel inner core, double braided compressed gas hoses are tig welded and come in female NPT or BSP threads.

Smooth Bore Inner Core : One of the most common causes of metal hose failure is “high velocity” gas flow. Because of the ribs on the corrugated type hose, high velocity flow (above recommended levels) can damage or crack a metal type hose. To avoid hose damage, it is important to know the velocity of gas flowing through the hose. We have provided charts that will help you determine velocity flow levels. If you find that a particular application requires a higher than recommended gas flow velocity, in this case we would suggest that you switch to a smooth bore PTFE or ETFE type hose (dependant on the gas). Smooth bore hose are designed to handle higher velocity gas flow requirements. Effusion: Metal inner core hoses will not effuse or diffuse gas. i.e. they have zero permeation: this is why they are preferred for high purity and hazardous specialty gases, as well as hydrogen and helium when in a constant pressurized application. Pressurized gas will permeate or effuse through the wall of the PTFE hose at rates consistent with the gas molecule size and weight, and with atmospheric gases this effusion is hardly noticeable and minimal. For hydrogen and helium, the ETFE or hose has typically 1/3 the effusion rate of a PTFE hose, so ETFE (or “post sintered”) is the recommended inner core material for H2 and He cylinder filling applications. Flexibility: Teflon hoses tend to be a bit more forgiving in terms of flexibility than all metallic hoses. If an application requires constant flexing, a PTFE or ETFE type hose will work best. Trailer Transfill/Cylinder Filling, Cylinder Cradles - High velocity: The inside of a Teflon gas service hose is smooth bore, whereas a metal inner hose is convoluted (ribbed). In high velocity applications (tube trailer transfill, cylinder fill) a smooth surface will work best. A convoluted hose in a high pressure drop(high velocity up to critical velocity) can experience internal hose vibration and fatique leading to cracking of the corrugated inner core. Trailer Transfill Liquid - Low velocity : When hydrogen or helium tube trailers are being filled at the plant in a slow volume method such as with a pump or compressor, the volume flow through the hose is typically within the velocity limitations to allow the use of a metal inner core hose. Typically lower pressures and temperatures are used in the transfer of liquid cryogenics. A metal hose will perform this job much better than a Teflon hose. However, it is important to ensure that the hose is not bent in more than one plane at a time. Failure to do so will result in premature hose failure. Static State: Static state would include applications where the gas remains in the hose over a long period of time. Polymer inner core hose will effuse gas. Whereas metal inner core hose has zero effusion. This becomes critical when the application involves smaller molecule gases, flammable, or toxic gases. Hydrogen, helium, and specialty gases are best delivered in a metal liner core hose. When delivering corrosive gases, Monel inner core hose is recommended. Cryogenic Hose: The low temperature of cryogenic liquids requires the use of a stainless steel inner core type hose. Metal Hose Limitations: It is important to ensure that the hose is not bent in more than one plane at a time. Such action will set up an inherent torque, which can contribute to premature hose failure when the hose is pressurized. When the hose is connected from one static point to another static point, it should make the bend easily without forcing the hose to arrive at its position to make the connection. Also as mentioned previously: Metal inner core hoses have a velocity limitation of 100 feet per second for a straight run, 50 fps for a 90degree bend, and 25 FPS for a 180 degree bend according to metal hose manufacturer’s rules of thumb. Calculations are available to project velocity data. LifeGuard™ Teflon vs. Metal Inner Hose Gas and cryogenic hoses are available with either Teflon of Metal inner hoses. To ensure long life, it is very important that you select the correct material for each application.

HYDROGEN HOSES | CRYOGENIC LIQUID CYLINDER HOSES | METAL PIGTAILS | LIFEGUARD COMPRESSED GAS HOSES | CARBON DIOXIDE BULK LIQUID TRANSFER HOSES WHAT IS LIFEGUARDTM ? A Flexible “Safety System” for use in the transfer of high pressure gases and liquids. Protect against the hazardous effects of high pressure hose rupture, pull-apart and failure. The LifeGuardtm design utilizes the unique, patent pending design that eliminates the potential for disaster through the use of an internal compression spring device connected to specially designed, normally unseated valves located on each end of the spring. In the event of hose separation, stretching to the point of an unsafe condition or coupling-to hose separation, the valves are released and instantly seat stopping the flow in both directions. APPLICATION: For certain applications, customers choose a metal “bellows-type” pigtail which provides an all welded, zero permeation and flexible alternative to pipe and tubing, even at cryogenic temperatures. The metal lined pigtail is reinforced with two layers of type 304 stainless steel braid (Monel® braid is optional) and is designed to provide maximum flexibility. In cases where adiabatic compression in PTFE is a concern, LifeGuard Metallic Pigtails are an excellent solution. CONSTRUCTION: All LifeGuard convoluted stainless steel inner core, double braided compressed gas hoses are tig welded and come in female NPT or BSP threads.

- 13. [email protected] | www.thesafesthose.com | Toll Free 855-GPSS-USA | 855-477-7872 Corrugated VS. Smooth Bore Inner Core : One of the most common causes of metal hose failure is “high velocity” gas flow. Because of the ribs on the corrugated type hose, high velocity flow (above recommended levels) can damage or crack a metal type hose. To avoid hose damage, it is important to know the velocity of gas flowing through the hose. We have provided charts that will help you determine velocity flow levels. If you find that a particular application requires a higher than recommended gas flow velocity, in this case we would suggest that you switch to a smooth bore PTFE or ETFE type hose (dependant on the gas). Smooth bore hose are designed to handle higher velocity gas flow requirements. Effusion: Metal inner core hoses will not effuse or diffuse gas. i.e. they have zero permeation: this is why they are preferred for high purity and hazardous specialty gases, as well as hydrogen and helium when in a constant pressurized application. Pressurized gas will permeate or effuse through the wall of the PTFE hose at rates consistent with the gas molecule size and weight, and with atmospheric gases this effusion is hardly noticeable and minimal. For hydrogen and helium, the ETFE or hose has typically 1/3 the effusion rate of a PTFE hose, so ETFE (or “post sintered”) is the recommended inner core material for H2 and He cylinder filling applications. Flexibility: Teflon hoses tend to be a bit more forgiving in terms of flexibility than all metallic hoses. If an application requires constant flexing, a PTFE or ETFE type hose will work best. Trailer Transfill/Cylinder Filling, Cylinder Cradles - High velocity: The inside of a Teflon gas service hose is smooth bore, whereas a metal inner hose is convoluted (ribbed). In high velocity applications (tube trailer transfill, cylinder fill) a smooth surface will work best. A convoluted hose in a high pressure drop(high velocity up to critical velocity) can experience internal hose vibration and fatique leading to cracking of the corrugated inner core. Trailer Transfill Liquid - Low velocity : When hydrogen or helium tube trailers are being filled at the plant in a slow volume method such as with a pump or compressor, the volume flow through the hose is typically within the velocity limitations to allow the use of a metal inner core hose. Typically lower pressures and temperatures are used in the transfer of liquid cryogenics. A metal hose will perform this job much better than a Teflon hose. However, it is important to ensure that the hose is not bent in more than one plane at a time. Failure to do so will result in premature hose failure. Static State: Static state would include applications where the gas remains in the hose over a long period of time. Polymer inner core hose will effuse gas. Whereas metal inner core hose has zero effusion. This becomes critical when the application involves smaller molecule gases, flammable, or toxic gases. Hydrogen, helium, and specialty gases are best delivered in a metal liner core hose. When delivering corrosive gases, Monel inner core hose is recommended. Cryogenic Hose: The low temperature of cryogenic liquids requires the use of a stainless steel inner core type hose. Metal Hose Limitations: It is important to ensure that the hose is not bent in more than one plane at a time. Such action will set up an inherent torque, which can contribute to premature hose failure when the hose is pressurized. When the hose is connected from one static point to another static point, it should make the bend easily without forcing the hose to arrive at its position to make the connection. Also as mentioned previously: Metal inner core hoses have a velocity limitation of 100 feet per second for a straight run, 50 fps for a 90degree bend, and 25 FPS for a 180 degree bend according to metal hose manufacturer’s rules of thumb. Calculations are available to project velocity data. LifeGuard™ Teflon vs. Metal Inner Hose Gas and cryogenic hoses are available with either Teflon of Metal inner hoses. To ensure long life, it is very important that you select the correct material for each application.
