An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 90° or 45° angle, though 22.5° elbows are also made.The ends may be machined for butt welding, threaded (usually female), or socketed, etc.When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow. Elbows are categorized based on various design features as below: Long Radius (LR) Elbows ? radius is 1.5 times the pipe diameter Short Radius (SR) Elbows ? radius is 1.0 times the pipe diameter 90 Degree Elbow ? where change in direction required is 90° 60 Degree Elbow ? where change in direction required is 60° 45 Degree Elbow ? where change in direction required is 45° A 90 degree elbow is also called a "90 bend" or "90 ell". It is a fitting which is bent in such a way to produce 90 degree change in the direction of flow in the pipe.
It is used to change the direction in piping and is also sometimes called a "quarter bend".A 90 degree elbow attaches readily to plastic, copper, cast iron, steel and lead.It can also attach to rubber with stainless steel clamps.It is available in many materials like silicone, rubber compounds, galvanized steel, etc. The main application of an elbow (90 degree) is to connect hoses to valves, water pressure pumps, and deck drains.These elbows can be made from tough nylon material or NPT thread.Źródło: https://en.wikipedia.org/wiki/Piping_and_plumbing_fittingThey can be associated with connecting new sanitary facilities or carrying out small repairs.
Conducting self-activity of the hydraulicSmall plants hydraulic predominantly take orders for minor plumbing work.All such work can be carried out also by plumbers self-employed.You just have to reckon with the fact that the services contract with an independent plumber probably will prolong the work carried out. However, this should not affect their quality, and sometimes it turns out that the plumber running his own business applies doubly to perform the outsourced tasks themselves. They may rely on both the exchange of a faulty seal and at the connection of the new tap.
Independent hydraulic works carried out in the homesHome handymen are very fond carry out the various repair work.Therefore, it happens also that alone make minor repairs or improvements hydraulic.The houses usually they exchange seals and pipes, which has already gathered a lot of dirt and hair and suds.
Similarly, in flats, where sometimes you also need to fix the toilet flush.In addition, home handymen often deal with repairs washing machines standing in a bathroom or dishwashers standing in the kitchen.So they can save some money and demonstrate their efficiency in front of family. But keep in mind that the performance of such work will be possible only if equipped house there are small seals and hydraulic tools..
