What are plumbing work?
Hydraulics is quite a complex area and not everyone can be found in it. In such matters require specialized knowledge and skills, and such work is also associated with great responsibility, because the slightest error can result in a major accident. Plumbing may involve many issues. Sometimes it will be installation of hydraulic, other times repairing the broken pipe or replace gaskets and scope of such work is very extensive. Specialists in the field of hydraulics are needed in each region, because each building are installed plumbing. So it is very important work, without which it would be hard for us to get around.
Quick plumbing repairs? Now it is possible. With the use of modern technology and advanced equipment any repairs or inspections related to hydraulic installations run much faster and do not require a major commitment plumber or more hours spent on searching failure. Until recently, this type of repair often lasting several days or even weeks, and today calling hydraulic service, we are sure that the failure will be repaired in a few hours. This is a great convenience not only for customers but also for specialists in the field of hydraulics. Today, everything is faster and easier, allowing for greater comfort and convenience.
Pipe type - elbow definition
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.
A 45 degree elbow is also called a "45 bend" or "45 ell". It is commonly used in water supply facilities, food industrial pipeline networks, chemical industrial pipeline networks, electronic industrial pipeline networks, air conditioning facility pipeline, agriculture and garden production transporting system, pipeline network for solar energy facility, etc.
Most elbows are available in short radius or long radius variants. The short radius elbows have a center-to-end distance equal to the Nominal Pipe Size (NPS) in inches, while the long radius is 1.5 times the NPS in inches. Short elbows are widely available, and are typically used in pressurized systems.
Long elbows are typically used in low-pressure gravity-fed systems and other applications where low turbulence and minimum deposition of entrained solids are of concern. They are readily available in acrylonitrile butadiene styrene (ABS plastic), polyvinyl chloride (PVC) for DWV, sewage and central vacuums, chlorinated polyvinyl chloride (CPVC) and copper for 1950s to 1960s houses with copper drains.
