What are the current emission standards for valve packing?

with Flexible Graphite Packing for Fugitive Emissions. Currently under development, the standard will use EPA Method 21 as a basis for the evaluation of fugitive emissions, with the leakage limit set at 100 ppm methane. It requires that the tested valve

Grounding vs Bonding — Part 8 of 12

Flexible metallic tubing — To qualify as an EGC, FMT (Art. 360) must terminate in fittings listed for grounding. The circuit conductors in the tubing must be rated at 20A or less, and the FMC must be no more than 6 feet long [250.118(7)(a)-(b)].

The History of Graphite

2018/8/15Flexible graphite can oxidize when exposed to air or other gasses, causing weight losses. In oxidizing atmospheres, oxidation of flexible graphite can begin at 975F (525C). However, thin-edged exposure of packings and gaskets has successfully withstood extended periods of air and process fluid temperatures of up to 1500F (815C).

Thin, Light, Flexible Heaters Save Time and Energy

2021/5/2EGC makes the heaters out of thin layers of varying materials that are bonded to form heater laminates. The inner layer, made of a flexible graphite foil (marketed separately by EGC as ThermaFoil), is electro-thermally conductive and typically laminated between a heat-conducting outer layer, and a protective insulating layer.

Behind the Equipment Grounding Conductor

Although it's rather simple component, an equipment-grounding conductor (EGC) serves a vital role in your overall electrical system. You use an equipment-grounding conductor (EGC) to ground the noncurrent-carrying metal parts of equipment. Its function is to keep your equipment as close as possible to ground potential and provide a safe path for ground-fault current to flow. A properly sized

Thin, Light, Flexible Heaters Save Time and Energy

Originating Technology/NASA Contribution Ice accumulation is a serious safety hazard for aircraft. The presence of ice on airplane surfaces prevents the even flow of air, which increases drag and reduces lift. Ice on wings is especially dangerous during takeoff, when a sheet of ice the thickness of a compact disc can reduce lift by 25 percent or more. Ice accumulated on the tail of an aircraft
