1986 ; Lootvoet 1986 ; McLean and Cripps 1986 ; Ogawa et al. Flash steam occurs in the condensate return lines when condensate discharges into these lines that are operating at a lower pressure.
The top of the discharge vent line should be cut at a 45-degree angle to dissipate the steam discharge thrust, to prevent capping of the pipe, and to visually signify to plant personnel that it is a safety valve vent line.
However, storage of fuel oil is less complex and typically is more attractive than LPG as secondary fuel.

Hydraulic shock can be easily described by using the example of a home faucet. WHAT SIZE STEAM LINE REQUIRES A WARM-UP VALVE? 2, Safe Handling and Transport of LPG in Bulk by Road Code of Practice No. Each valve for steam systems requires documentation of the maximum pressure rating and the maximum temperature of the steam.
No matter how well the steam line is insulated, the heat latent energy will be transferred from steam into the atmosphere through the insulation. The purpose of the drain or vent openings is to allow any liquid that might accumulate above the discharge valve to drain.
The proper selection, installation, and use of safety valves require a complete understanding of the ASME code and any additional requirements adopted by insurance companies or the local jurisdictional authority. West, Brown, and Welker 1975 ; Neff, Meroney, and Cermak 1976 ; R. The discharge outlet of the vent pipe should be piped to the closest location where free discharge of the safety device will not pose any safety hazard to personnel.
Safety Valve Installation on Heat Transfer• If the wire seal on the safety valve is not intact, the valve is no longer in compliance with the code and should be replaced as soon as possible. 1991 ; Pakleppa 1991 ; Tornay, Gilmore, and Feskos 1991 ; Wayne, Bockenhauer, and Gray 1991 Shipping statistics: J.

Steam Isolation Valves One of the most common applications is the steam line isolation valve installation. Install a steam line drip leg pocket with a steam trap station ahead of the isolation valve.
This can be accomplished by preparing the steam piping before the steam piping has been installed or by conducting controlled steam blows after the installation. Plint, in2012 Liquefied Petroleum Gas LPG LPG is often referred to as autogas or auto propane.
Use a double-block valve with a bleed valve.
The drains on the drip pan elbows are designed to collect any condensed liquid and rain and allow flow safely away from the safety valve.
It is possible to have high-pressure steam systems operating without water hammer and enjoy a long operational life from the steam components.
