1. Pipe. Flashcards
- Other name for asbestos-cement pipe?
Transit pipe.
- Material for buried portions of the standpipe system?
- Ductile-iron pipe, centrifugally cast.
- Electric-resistance welded pipe.
- Welded and seamless steel pipe black or hot-dipped zinc-coated.(galvanized).
- Coper tube:
a) seamless copper tube;
b) wrought seamless copper and copper-alloy tube. - Brazing filler metal (Classifications BCuP-3 or BCuP-4).
- How many zinc has galvanized pipe?
4 oz per sq. foot.
- Standards of ferrous piping:
- Ductile-iron pipe, centrifugally cast, for water or other liquids -
- Electric-resistance welded steel pipe -
- Standard specification for black and hot-dipped zinc-coated (galvanized) welded and seamless steel pipe for fire protection use -
- Standard specification for piping, steel, black and hot-dipped, zinc-coated, welded and seamless -
- Welded and seamless wrought steel pipe -
- Ductile-iron pipe, centrifugally cast, for water or other liquids - AWWA C 151.
- Electric-resistance welded steel pipe - ASTM A 135.
- Standard specification for black and hot-dipped zinc-coated (galvanized) welded and seamless steel pipe for fire protection use - ASTM A 795.
- Standard specification for piping, steel, black and hot-dipped, zinc-coated, welded and seamless - ASTM A 53.
- Welded and seamless wrought steel pipe - ANSI B36, 10M.
- General use of plastic pipe.
- Plastic pipe and fittings shall not be used for waste and went piping.
- Supply piping is not permitted to be plastic.
- Plastic piping and fittings may be used in residential buildings five stories or less in height in drain, waste and venting systems.
- Use of corrugated polyethylene piping and fittings?
A diameter of 12 inches or more may be used in construction with any type of building for underground yard drainage and storm water piping when used outside of the foundation wall of the building and not connecting to any piping system from the interior of the building.
- What are the three types of copper water tube that are installed with sweat solder fittings? Compare the wall thickness of the three types; also compare these wall thickness with standard iron pipe in the smaller sizes as for water piping in household plumbing?
The three type designations are: K, L, and M. In the smaller sizes used in household plumbing, the wall thickness of type M (the thinnest) is approximately 70 percent of that of type L, which , in turn , is about 70 percent of that of type K .The wall thickness of “standard” iron pipe is about twice that of type K, 2-1/2 to 3 times that of type L, and nearly 4 times that of type M.
- TFE.
Tetra-flouro-acetilin.
- Sizing of copper water tubing?
The actual outside diameter from 14” to 12” is always 1/8” larger than the standard size designation.
- What is seamless copper pipe?
It is available in iron pipe sizes from 1/8” to 12” and in wall thicknesses designated as regular and extra strong.
