The Different Types of Plumbing Pipes and Fittings

The Different Types of Plumbing Pipes and Fittings

Pipe fittings are in great demand for all pipes and plumbing systems used in industrial and commercial applications. The use of fittings enables the joining, installation, and termination of pipes where necessary. There are several sizes and shapes of fittings available. They play a crucial role in plumbing and pipe systems. Hundreds of different customizable fits are made by manufacturing companies. There is a unique fitting for each type of pipe or tube, although most pipe fittings have a few characteristics. Purpose of a pipe fitting:

  • connecting the pipe or tube bores of two or more.
  • pipes being connected together.
  • connecting a pipe to another device.
  • connecting a pipe to another device. regulating the flow of a fluid or liquid.
  • controlling or maintaining the flow.
  • sealing a pipe and closing it.

    Types of Plumbing pipes

PVC Pipes – PVC plumbing pipes are well known for their flexibility, lightweight, and obstruction resistance. PVC piping is often used as part of a sink, toilet, or shower drain line, however, it is occasionally used as the primary water supply pipe in a residence.

PEX Pipes – Water supply lines are frequently made of PEX, an economical plastic plumbing material that can handle both hot and cold water.

ABS Pipes – Plastic pipe made of acrylonitrile butadiene styrene (ABS), which is identical to PVC but can be distinguished by its dark colour, is a common building material. Only waste and drain pipe uses ABS, which is renowned for its extended lifespan.

Copper Pipes – The usual hard pipe in the plumbing business is copper, which has a lifespan of more than 50 years. Copper pipes are available in two categories: rigid and flexible, and they can sustain high water pressure. They also come in several grades of thickness.

Water supply lines are normally made of hard copper pipes, but places where the malleable copper may bend, such narrow areas, demand for flexible copper pipes.

Galvanized and cast iron pipes – Although though cast iron and galvanised plumbing are rarely seen in newly built homes, if you live in an older house that was constructed in the early 20th century, you could find these pipes. Some water distribution systems continue to use cast iron pipes today.

Type of pipe fittings:

Pipe fittings, sometimes referred to as pipe connectors, join two pipes together to extend the run or switch the flow in a plumbing system. Although the majority of fittings have identically sized apertures on both ends, some are made with variously sized openings and act as a bridge between different pipe sizes.

Tee, Wye Fittings – Three sections of pipe can be connected using tee and wye fittings. A supply line can be divided using a tee, which has one inlet and two outlets at 90-degree angles in the shape of a “T,” or two lines can be combined into one outlet. In drain applications, a wye has a “Y” design, where the two inlets converge at a 45-degree angle into a single outlet. Sanitary weyes let wastewater enter a drain pipe from the side, and the second “Y”-shaped section of the weep allows sewage gases to vent upward when it is aligned with the pipe.

Cross Fittings – Crosses feature four pipe openings: one inlet, three outlets, or, depending on the situation, three inlets and one outlet. These less frequent four-way connectors are employed in a few irrigation and sprinkler applications.

Fittings for Elbows – Elbows modify the flow direction between two pipes. Common elbows are used to make turns and have bends of 90, 60, 45, and 22 1/2 degrees. To get around obstacles in the pipe run, they can be connected together.

Coupling and Adapter Fittings – To link two pipes,  permanently, pipe couplers slide over the exterior of the pipes. A reducer/reducing coupling joins a larger pipe to a smaller pipe in order to reduce flow. Adapters are used for joining two pipes of different sorts,. For instance, a simple pipe’s end might be equipped with an adaptor to enable a threaded connection on the opposite side.

Bushing Fittings – Bushings are used to join two pipes of various diameters.  The bigger pipe may fit within the bigger bushing, which has a bigger diameter. The smaller pipe is then placed into the bushing’s smaller end.

Union Fittings – Unions join two comparable pipes, just like couplings do. With pipe unions, two pipes are connected by tightening a nut or threaded ring in the centre of the fitting.

Trap Fittings – Drainage pipes beneath kitchen and bathroom sinks include horizontal dips or bends known as traps. They have a “U” or an upside-down “P” form and have two uses. To first build a barrier that stops sewage gases from ascending into the house, drain water is first trapped in the arc.

Flange fittings – These are flat, rounded fittings that use bolts or clamps to provide a tight seal. When pipes go through walls, ceilings, or floors, they are utilised. This holds a toilet to the floor and joins the drain pipe to the toilet drain.

Cap fittings – To halt the flow of water or gas, a cap is placed over the end of a pipe. During a plumbing project, these fittings can be temporarily utilised to cut off supply or used to permanently terminate a pipe.

Plug Fittings – Plugs, akin to caps, are used to plug the aperture at the end of a pipe. The distinction is that plugs seal the threaded pipe hole, whereas caps cover the aperture. They are frequently discovered in sewer system cleanout areas.

Nipple Fittings – For joining two female-threaded pipe ends or fittings, nipples, which are brief lengths of pipe with male threads on both ends, are utilised.
