As the product enters the inlet of the elbow, it typically continues moving straight ahead to the first (or primary) impact zone. The product is then deflected at an angle toward the outlet of the elbow. The deflection angle is determined by the elbow design, the product’s characteristics, the conveying velocity, and specific load (also called the product-to-gas ratio). In many designs, the product will hit one or more secondary impact zones before exiting the elbow.
1) 90° Short Radius Elbows:
These elbows have a Center-to-Face dimension of 1.0 X diameter. They are typically used in tight areas where clearance is the main issue
2) 90° Long Radius Elbows:
These elbows have a Center-to-Face dimension of 1.5 X diameter. They are the most common type of elbow and used when space is available and flow is more critical.
3) 45° Pipe Elbow
45° Pipe Elbow is also known as “45 bends or 45 ells”. The 45° pipe elbow is used to connect tubes at a 45° pipe angle. As the name suggests, this is a pipe fitting device which is bent in such a way to produce 45° change in the direction of flow of the fluid/gas in the pipe. They are typically made as LR (Long Radius) elbows. These types of elbows are available in various sizes (in mm or inches). They are available with different male to female BSP thread connections. Providing a wide choice of colors, these 45° elbows can be manufactured to meet different specifications, in terms of size and diameter.
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. If the two ends of coupling are of different standards or joining methods, the coupling is called an adapter.
Pipe Union is a type of fitting equipment designed in such a way to unite two pipes which can be detached without causing any deformation to the pipes. Any kind of small diameter piping connections requiring a positive seal and easy assembly as well as disassembly is made with the help of a pipe union. In other words, the pipe unions can disjoint two pipes very easily.
Three parts of pipe union:
- A nut
- A female end
- A male end
With the joining of the female and male ends, the nuts are used to provide the necessary pressure to seal the joint.
The parts of the pipe union are normally locked together by at least one radial screw or nut with a sized cross-section. When severe pulling stress is applied onto the pipe union from the outside, the locking screw breaks and removes the two parts of the union, which in turn separates together with the pipes to which they are attached. Under normal conditions elastically stressed sealing objects ensure the maintenance of water tightness between the union parts.
The nipple is a fitting, consisting of a short piece of pipe, usually provided with a male pipe thread at each end, for connecting two other fittings. The length of the nipple is usually specified by the overall length with thread. It may have a hexagonal section in the center for a wrench to grasp (sometimes referred to as a “hex nipple”), or it may simply be made from a short piece of pipe (sometimes referred to as a “barrel nipple” or “pipe nipple”). A “close nipple” has no unthreaded area; when screwed tightly between two female fittings, very little of the nipple remains exposed. A close nipple can only be unscrewed by gripping one threaded end with a pipe wrench which will damage the threads and necessitate replacing the nipple, or by using a specialty tool known as a nipple wrench (or known as an internal pipe wrench) which grips the inside of the pipe, leaving the threads undamaged. When the ends are of two different sizes it is called a reducer or unequal nipple.
Pipe reducer is a kind of pipe fitting that joins two pipes of different diameters. The pipe reducers are available in a range of materials depending on the end-use of the products and these fittings are manufactured in inch and metric size.
Pipe Tee is a type of pipe fitting which is T-shaped having two outlets, at 90° to the connection to the mainline. It is a short piece of pipe with a lateral outlet. Pipe Tee is used to connect pipelines with a pipe at a right angle with the line. Pipe Tees are widely used as pipe fittings
Pipe caps act as a protective devices and are designed to protect pipe ends of various shapes. The main purpose of using pipe caps is to waterproof the connections. They are also used to close the ends of hydraulic or pneumatic pipes and tubes.
