What are standard pipe fittings?
British Standard Pipe is a set of technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings by mating an external thread with an internal thread. It has been adopted as standard in plumbing and pipe fitting, except in North America, where NPT and related threads are used.

What are fittings and fixtures?
Fixtures are items which are attached to the property; fixed, if you will. Fittings are items which aren't attached to the property, unless by the slenderest of fingernails (or more likely, screws).
What is the name of the joint in pipe fitting?
A spigot joint is a type of pipe fitting connection that is inserted into another pipe fitting. The spigot end typically has the same outer diameter as the pipe and is usually fitted into another joint called a bell or socket. Together, these two elements form what is commonly known as a bell and spigot joint.

What are pipe flanges?
A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.

What is pipe fitting?
Pipe fittings are components used to join pipe sections together with other fluid control products like valves and pumps to create pipelines. The common connotation for the term fittings is associated with the ones used for metal and plastic pipes which carry fluids. There are also other forms of pipe fittings that can be used to connect pipes for handrails and other architectural elements, where providing a leak-proof connection is not a requirement. Pipe fittings may be welded or threaded, mechanically joined, or chemically adhered, to name the most common mechanisms, depending on the material of the pipe.
What is concrete pipe fitting?
Concrete pipe fittings are available in a variety of styles suitable to their application in large civil projects such as storm-water control. Aside from the typical wye connections, specialized fittings include utility hole portals and various styles of vaults. Typical connections use shouldered ends on the fittings which mate with counterparts on the receiving pipes. A rubber gasket provides for a leakproof joint.
What is a hubless pipe?
Fittings for cast iron pipe fall under hubless and bell-and-spigot styles. Hubless designs rely on elastomeric couplers that are secured to the outer diameters of the pipe or fitting by clamps, usually a stainless steel band clamp that compresses the elastomeric material and forms a seal. These hubless or no hub designs are sometimes referred to as rubber pipe couplings or rubber plumbing couplings and are especially popular for transitioning from one material to another—from copper to cast iron, for instance. Bell-and-spigot, or sometimes, hub-and-spigot, fittings are joined today primarily with elastomeric gaskets that fit inside the bell and accommodate the insertion of the plain pipe end or fitting. Older systems before the 1950s were caulked using a combination of molten lead and a fibrous material such as oakum. Cast iron pipe is sometimes joined with bolted flanges, or in some cases, mechanical compression connections. Flanged joints employed in underground applications can subject the pipe to settlement stresses unless the pipe is adequately supported.
What is threaded flange?
The threaded flange is suitable only for low- to medium-pressure applications.
What type of pipe fittings are used for vitrified clay?
Like cast iron, bell-and-spigot is the usual coupling method for these fittings, with an O-ring or gasket used to seal the joint.
Why do we use flanges in pipelines?
The use of flanges makes breaking the pipeline feasible so as to enable replacement of valves, etc. Most pipeline equipment such as pumps and compressors are also connected via flanges for this same reason.

What is a union in piping?
Piping Union. Unions are used as an alternative to flanges connection in low-pressure small bore piping where the dismantling of the pipe is required more often. Unions can be a threaded end or socket weld ends. There are three pieces in a union, a nut, a female end, and a male end.
What is the diameter of a long radius elbow?
In a long radius elbow, the centreline radius is 1.5 times the nominal size of the pipe or you can say 1.5 times the diameter of the pipe. Normally long radius elbows are used in piping as pressure loss is less as compared to short radius elbow. It required more space than a short radius elbow.
What size is a miter bend?
Miter bends are not standard pipe fittings they are fabricated from pipes. Usually, they are preferred for size 10” & above because large size elbow is expensive. The use of miter bend is restricted to the low-pressure water line. Miter bend can be fabricated in 2, 3, & 5 pieces.
