What material is used for natural gas piping?
The list of gas piping materials - part of your question, depending on where the pipe is used, includes aluminum (in some locations and never below ground), brass (yellow - the old traditional gas piping found indoors in older buildings), copper type L or K rated for gas systems, iron (black ductile iron) above ground
riser pipeline - a vertical pipe in a building. riser main, riser pipe, riser. pipage, pipe, piping - a long tube made of metal or plastic that is used to carry water or oil or gas etc.
- A riser is a pipe that connects an offshore Floating Production Structure or a Drilling Rig to a sub-sea system either for production purposes such as drilling, production, injection and export, or for drilling, completion and workover purposes.
- The flowing back of used, contaminated, or polluted water from a plumbing fixture or vessel into a potable water supply due to a negative pressure in the pipe. Branch. Any part of the piping system other than the main, riser, or stack. Branch Vent. A vent connecting one or more individual vents with a vent stack.
- Rough In means to bring in the various lines (Plumbing pipes, duct work, electrical conduit) to the space, but not make the final connections. For plumbing, this would be the pipes in the walls and floors that lead to the sinks, bath, toilets, etc, but not actually hooking up those fixtures.
Anodeless Riser. from Glossary (2016) by U.S. Department of Transportation & U.S. Department of Transportation, Pipeline and Hazardous Materials Safety Administration. A steel casing with a plastic pipe inside. The plastic pipe inside the steel casing is the service line carrying gas to the customer meter.
- Cable that is run between floors in non-plenum areas is rated as riser cable. The fire requirements on riser cable are not as strict. Thus, plenum cable can always replace riser cable, but riser cable cannot replace plenum cable in plenum spaces.
- Since Ethernet cables have an RJ45 connector on each end, Ethernet cables are sometimes also called RJ45 cables. The "RJ" in RJ45 stands for "registered jack," since it is a standardized networking interface. The "45" simply refers to the number of the interface standard.
- What most people don't know is that although these terms are often used to refer to the same cables, they are not the same. RJ45 is the electrical interconnection standard that defines the connector and how the wires are arranged at the end of the cable while CAT5 is a standard regarding Ethernet cables.
