The system of valves enables us to isolate portions of our system to perform routine maintenance or repair of leaks or ruptures. All of the valves .
To automatically shut off the flow of diesel fuel, fuel oil, kerosene, and oil in case of fire, these UL listed valves automatically close and the handle permanently fuses in place when the ambient temperature reaches Â° F.

EVALUATION OF SAFETY SHUTOFF VALVE SYSTEM ON METHANE GAS PIPELINES UNDER MINE FIRE CONDITIONS By Patrick A. Kinek, ' Thomas E. Marshall, and Gerald L. Finfinger ABSTRACT The purpose of this investigation was to evaluate the integrity of the existing shutoff valves and actuators used under.

Evaluation of safety shutoff valve system on methane gas pipelines under mine fire conditions. The fail-safe control system uses a pneumatically actuated valve (fig. 1) to shut off the flow of methane from the degasification borehole to the meth- ane drainage pipeline when the system detects an unsafe condition.

of America (INGAA), and it is our responsibility to embrace pipeline safety by implementing stringent safety programs and practices every step of the way.
Safety is our core value, and the following principles guide everything we do: 1. Our goal is zero incidents - a perfect record of safety and reliability for the national pipeline Size: 1MB.
For safety reasons, during pipeline maintenance, the pipeline operator may have to release natural gas into the atmosphere.
To reduce the methane emitted during maintenance, operators try to eliminate the amount of natural gas within a section of pipeline before opening the valve, or divert the gas around the section of pipe. The purpose of a safety shut-off system is to automatically shut off the gas supply to the premises, or a selected part of the premises such as a commercial kitchen, when the fire extinguishing system or.
must close the valves remotely and/or automatically. If the control system is part of the solution, the system must monitor the pipeline pressure, react if it detects linebreak conditions, and signal the actuator to close the line valves.
Overall, the system must be reliable with minimal maintenance. As the map shows, many busy highways cross pipelines carrying natural gas.
Shutoff valves. Pipeline Safety: Safety of Gas Transmission and Gathering Pipelines. This NPRM proposes to revise the Pipeline Safety Regulations applicable to the safety of onshore gas transmission and gathering pipelines.
SpeciThcs About Natural Gas Pipelines Pipeline Briefing Paper 2 Last updated: September Page 1 Introduction to Pipelines There are over million miles of fuel pipelines in the United States. Who regulates pipelines and under what set of regulations depends on what the pipeline.
