Gas pipe bondingFocuses on a United States rule for bonding gas piping systems. Concern of the electric and gas industries; Resulting debate on how big does the bonding conductor need to be; National Fuel Gas Code.Hartwell, Freder...
Even if you cause what appears to be only minor damage to the pipeline, immediately notify the pipeline company. A gouge, scrape, dent or crease to the pipe or coating may cause a future rupture or leak. It is imperative that the pipeline owner inspects and repairs any damage to the lin...
The DBE-PEG filler acts as a spacer, which restricts the hydrogen bonding between polymer chains and improves the space between polymers, leading to increase in chain mobility and free volume. The decrease in the glass-transition temperature as well as the crystallinity also results in enhanced ...
There is no chemical bonding existing between the host water molecules and the encapsulated guest molecule. A substantial number of cages are occupied by guest molecules for the stability of the hydrate; however, some cages in the structure can still be vacant. These hydrates may occur at a ...
In the event of a lightning strike on or near the home, you need to dissipate that massive energy into the earth. If you don't, that energy can arc between materials, possibly causing pinholes, fire, explosions, etc. Bad stuff. The bonding clamp should go on either the first brass nut...
3. Check the earth (ground) continuity between your electrical supply outlet earth (ground) and the functional earth (ground) terminal on the rear of the analyzer. 4. If a local earth bonding is required the functional earth stud can be used. The earthing cable must be kept to less than...
and inorganic bonding materials such as epoxy, due to their stable chemical properties,low thermal conductivityand low cost, are light in weight and highly fracture resistant. A single cylinder or a cluster of cylinders can be used on a vehicle to store CNG. The maximum mass of the gas carri...
When the particle temperature increases to 100 °C, the minimal particle velocity for successful bonding reduces by approximately 14 m/s, and the temperature–velocity relationship is nearly linear [15]. Understanding of the particle temperature map and its dependency on gas temperature is ...
In the exhaust gas purification catalyst of Patent Literature 1, however, Pt and Rh co-exist inside the partition wall, and hence sintering (grain bonding) between Pt and Rh occurs when the catalyst is exposed to high temperature. The purification performance on exhaust gas may drop as a resu...
bonding occurs between a first layer formed from a blend of at least one aliphatic thermoplastic urethane and a copolymer of ethylene and vinyl alcohol, and a second layer of thermoplastic urethane. In addition to the occurrence of hydrogen bonding, it is theorized that there will also generally...
