What is a reducer in plumbing?
A reducer is a kind of pipe fitting used in process piping that reduces the pipe size from a larger bore to a smaller bore (inner diameter). The length of the reduction is usually equal to the average of the larger and smaller pipe diameters. There are two main types of reducer : Concentric reducers .
What is a 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.)
Which fitting is best for plumbing?
Copper Pipe Since the 1960s, copper piping has been the standard for most home plumbing applications. The long lifespan and durability of this piping makes it an excellent choice for many applications. It tolerates heat well and is extremely resistant to corrosion.
What are the types of pipe fittings?
Tee, Wye, Cross and Elbow Fittings. Tee & Wye Fittings – Tees and wyes are used to connect three pieces of pipe. Coupling, Adapter, Bushing and Union Fittings. Trap and Flange Fittings. Cap, Plug and Nipple Fittings.
Why reducer is used at pump suction?
Eccentric reducers are used at the suction side of pumps to ensure air does not accumulate in the pipe. The gradual accumulation of air in a concentric reducer could result in a large bubble that could eventually cause the pump to stall or cause cavitation when drawn into the pump .
What are the types of fitting?
There are many different kinds of fittings, made from a variety of materials: some of the most common types are elbows , tees , wyes, crosses, couplings, unions , compression fittings, caps, plugs and valves.
What is straight coupling?
Straight coupler to connect two pipes together, end to end. This slip-on pipe fitting is designed for use with standard 1-1/2″ pipe (aluminum or steel).
Why is PEX plumbing bad?
PEX failures Piping fails when the pipes are exposed to chlorine that is within the water, exposure to direct sunlight before its installation. Furthermore PEX pipe is vulnerable when it comes in contact with such solutions as petroleum products and oxygen. It can leach toxic chemicals from pipe material also.
Is brass or stainless steel better for plumbing?
Brass is also able to absorb and withstand more heat than plastic, making brass valves an optimal choice for at home plumbing systems. One significant difference between stainless steel and brass valves is that brass valves tend to accept welding better than stainless steel valves. This offers some versatility.
Which is better PVC or copper plumbing?
Quieter, even at high pressures and water speeds. Resists corrosion and impact damage better than copper pipe because plastic doesn’t corrode, and because PVC pipe is thicker than copper pipe . This means it’s better for areas where the pipe will be exposed in high-traffic areas.
What is 1.5d bend?
The D represents the outside diameter of the pipe, measured in inches. For instance, a 1.5D bend would feature a curve 1.5 times larger than the diameter of the pipe to be bent , so if you needed to bend a pipe 2 inches in diameter with a 1.5D bend , you would end up with a bend of 3 inches in radius.
What is the difference between pipe fitting and plumbing?
While a plumber works with basic types of pipe including copper and PVC found in residences, a pipefitter works with high pressure, specialized pipes . Plumbers deal with drinking water and water waste disposal systems. Pipefitters work with pipes that contain hazardous materials including chemicals and gases.
