If the 3 sides of T-fitting are similar in size then it is called as Equal tee otherwise it is called as Unequal tee. The advantages of this method are durability, speed, neatness, and safety. Some crimped fittings are designed to be used with copper tubing, without requiring flux or filler metal. Although crimped fittings are suitable for drinking-water pipes and other hot-and-cold systems , they are substantially more expensive than sweated fittings. Where many connections must be made in a short period of time , soldering is quicker and less expensive joinery than compression or flare fittings.
It is like a concentric reducer that maintains a centerline of the pipe but small in size. A pipe tee is used for distributing or collecting the fluid from the run pipe. It is a short piece of pipe with a 90-degree branch at the center.
In Concentric reducer which is also known as a conical reducer, the center of both the ends is on the same axis. When the center lines of the larger pipe and smaller pipe are to be maintained the same, then concentric reducers are used.
McAlpine valves, such as the McAlpine VP50P air admittance valve, features a dual-fit synthetic rubber finger seal for 3” or 4” soil pipe. Direct the flow of water outside a property with overflow pipes. Our range of PVC overflow pipes are available to buy in 30m, in either black or white. Aquaflow pipes come in a variety of sizes and shapes to complement the property design.
Depending on the connection technology and application, basic skills may be sufficient, or specialized skills and professional licensure may be legally required. This fitting differs from a standard cross in that two of the ports have curved inlets. 9000 class fittings are available in only the socket weld type. There are two types of the reducer used in piping Concentric & Eccentric. Generally, crosses are not used in process piping to transport fluid. But forged crosses are common in the firewater sprinkler line.
This view looking upwards through a hole in the ceiling shows a traditional leaded hub joint and a more recent rubber-sleeved hubless connection . There are similar fittings for both sweat and solvent joinery. Since they are not “tapped” , they are simply called reducing bushings. 3000 & 6000 class fittings are available in both Threaded and Socket Weld types.
“plumbing – How do I make my bathroom pipes more practical? – Home Improvement Stack Exchange”. This is also an indication that a clean-out fitting could be installed to provide easier future access. Cast iron piping was traditionally made with one “spigot” end and one “socket” or “hub” end (cup-shaped).
An advantage of this type of fitting is that the pipe it is connecting to does not need to be cut to a precise length; the slip joint can attach within a range of the end of the inserting pipe. Many slip fittings may be tightened or loosened by hand, for easier access to residential drainpipe systems . Because they operate at low pressure and rely on gravity to move fluids , drain-waste-vent systems use fittings whose interior surfaces are as smooth as possible. Freshly cut ends of pipe segments are carefully deburred to remove projecting slivers of material which may snag debris which can build up to cause blockages. This internal smoothness also makes it easier to “snake out” or “rod out” a clogged pipe with a plumber’s snake. An elbow is installed between two lengths of pipe to allow a change of direction, usually a 90° or 45° angle; 22.5° elbows are also available.
Long elbows are used in low-pressure gravity-fed systems and other applications where low turbulence and minimum deposition of entrained solids are of concern. They are available in acrylonitrile butadiene styrene , polyvinyl chloride , chlorinated polyvinyl chloride , and copper, and are used in DWV systems, sewage, and central vacuum systems. This section discusses fittings primarily used in pressurized piping systems, though there is some overlap with fittings for low-pressure or non-pressurized systems. Specialized fittings for the latter setups are discussed in the next major subsection.
Lightly lubricate the thread and cone of the assembly stud and the thread of the union nut. However, the O-ring must be removed before welding, and any stray welding material must be removed from the O-ring groove and the fitting hole. Plug is a component of plumbing component which is generally used to close pipe opening during inspections and repairs. In use, the spigot of one segment was placed into the socket of the preceding one and a ring of oakum was forced down into the joint with a caulking iron. Ideally, this would be done by pouring in molten lead, allowing it to set, and hammering it tightly with a caulking tool. If this was not possible due to position or some other constraint, the joint could alternatively be filled with lead wool or rope, which was forcibly compacted one layer at a time.
Socket weld and Threaded Pipe Fittings are forged products and classified based on their pressure-temperature rating. These fittings are available in four pressure-temperature rating class. It used to connect pipe to pipe or pipe to swage or nipple. Click the spin controls to enter number of pipe fittings for each pipe section.

With high peak-flow volumes, the design and construction of these systems may resemble those of storm sewers. Never let that be the case with our selection of copper tubes, stainless steel tubes and different plastic pipe options. Long radius pipeline bends are used in fluid transportation lines which required pigging. Due to their long radius and smooth change of direction, the pipe bend has very less pressure drop, and a smooth flow of fluid & pig is possible.
