电子游戏登录注册Pipe elbows are used to be installed between two lengths of pipe or tube allowing a change of direction,usually these elbows distinguished by connection ends.

A right-angled bend in a pipe or conduit; an elbow.
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.
Pressure: SCH5 to SCH160
Size range: 1/2 to 56 inches (DN 15 to DN 1,400mm), 22.5 Deg, 45 Deg, 90 Deg, 180 Deg
External arc length of elbow
Process: butt welding, seamless, threaded , or socketed
By default, there are 5 opportunities, the 45°, 90° and 180° elbows, all three in the "long radius" version, and in addition the 90° and 180° elbows both in the "short radius" version.
Long Radius (LR) Elbows – radius is 1.5 times the pipe diameter
Short Radius (SR) Elbows – radius is 1.0 times the pipe diameter
Elbows are split into two groups which define the distance over which they change direction; the center line of one end to the opposite face. This is known as the "center to face" distance and is equivalent to the radius through which the elbow is bent.
电子游戏登录注册Here below, for example, you will find the center to face distance of NPS 2 elbows (the A distance on the image)
90°-LR : = 1½ x 2(NPS) x 25.4 A=76.2 mm
180°-LR : = 2 times the 90° LR elbow A电子游戏登录注册=152.4 mm
90°-SR : = 2(NPS) x 25.4 A=50.8 mm
180°-SR : = 2 times the 90° SR elbow A=101.6 mm
The center to face distance for a "long" radius elbow, abbreviated LR always is "1½ x Nominal Pipe Size (NPS) (1½D)", while the center to face distance for a "short" radius elbow, abbreviated SR even is to nominal pipe size.
3D elbows as an example, are calculated with:
3(D) x 2(NPS) x 25.4
电子游戏登录注册90 Degree Elbow – where change in direction required is 90°
45 Degree Elbow – where change in direction required is 45°

Abrasion resistant piping systems are widely used at coal-fired power plants for a variety of purposes, including the conveyance of coal ash slurry to nearby settling ponds, the transfer of limestone slurry to absorber spray towers for removal of sulfur dioxide (SO2) and hydrogen chloride (HCl) from flue gases and for transporting away the calcium sulfate by-product of the flue gas desulfurization process.
