What is a hub in piping?
As previously stated, the hub of the pipe is the female “bell” end of the pipe, which leaves the male end of the pipe the no-hub end. The no-hub connection option is probably the most used by nonprofessionals due to the ease of installation. All that is needed is a no-hub coupling to attach the drain to the pipe.
What comes under pipe fittings?
A pipe fitting is a threaded fitting that comes in different shapes to make different plumbing configurations. Pipe fittings include tees, elbows, y-fittings, couplings, reducers.
Which tool is used on pipe and pipe fittings?
Pipe Wrench The pipe wrench serves as a plumber’s largest wrench. Plumbers use these heavy tools to tighten and loosen nuts and fittings on pipework. They typically use two of these wrenches together—one to hold a pipe in place and the other to rotate the nut or fitting in the appropriate direction.
What are pipe adapters used for?
A fitting or adapter is used in pipe systems to connect straight sections of pipe or tube, adapt to different sizes or shapes, and for other purposes such as regulating (or measuring) fluid flow.
What is a hub joint?
Hub connectors or hub and clamp joints are an alternate method of joining pipes as compared to traditional ASME B16. 5 pipe flanged joints. Pipes and equipment can easily be joined using clamp and hub connectors as this metal-to-metal sealed connector is highly reliable and easy to assemble. Two clamps. One seal ring.
What is no hub in plumbing?
Intended for use with DWV systems, no-hub couplings are used to join cast iron soil pipe that does not have the traditional Hub and Spigot. They are normally installed using a torque wrench. Generally, they have more clamps and provide a greater band load than standard no-hub couplings.
What is coupling in plumbing?
A coupling (or coupler) (used in piping or plumbing) is a very short length of pipe or tube, with a socket at one or both ends that allows two pipes or tubes to be joined, welded (steel), brazed or soldered (copper, brass etc.) together.
What is equipment in piping?
Arrangement of equipments and piping is a primary activity of a piping engineering department. Preliminary equipment layout is done before piping study. Equipment layout and piping layout is done as per general industry practice as well as piping design basis, process flow, gravity requirements, structure philosophy.
What is socket weld fittings?
A Socket Weld is a pipe attachment detail in which a pipe is inserted into a recessed area of a Valve, fitting or flange. In contrast to buttweld fittings, Socket Weld fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller.
What is no hub pipe and fittings?
No-Hub Pipe & Fittings. ASTM 888: Specification for Hubless cast iron soil pipe and fittings for sanitary and storm drain, waste, and vent application. Scope: This specification covers hubless cast iron pipe and fittings used in sanitary drain, waste, and vent (DWV), sewer, and storm drainage applications.
What is a hub on a copper pipe?
It’s the female end of the pipe. The inside diameter of the hub is designed to be the size of the outside diameter of the pipe. The gap between the two is made water tight in various ways. A rubber gasket, lead and oakem, and solder, etc. The bell on a copper fitting is a hub. The hub is also referred to as a bell, hence “Bell & Spigot” pipe.
What are hubless cast iron fittings used for?
Scope: This specification covers hubless cast iron pipe and fittings used in sanitary drain, waste, and vent (DWV), sewer, and storm drainage applications. This system is intended for use in nonpressure applications.
What is a spigot connection in plumbing?
The end connection of a fitting that is to be assembled into another fitting is called the “Spigot.” The spigotend of a fitting has the same outside diameter as pipe. The common female connection of PVC fittings is referred to as the socket or hub, and the spigotend of a fitting can be inserted into a Hubor Socket. Click to see full answer.
