Buttweld Pipe Fittings

45 degree elbow, also called "45 bends or 45 ells" are typically made as LR (Long Radius) elbows. Available in various sizes (in mm or inches), 45 degree pipe elbow is available with different male to female BSP thread connections. Providing a wide choice of colors, these elbows can be manufactured to meet different specifications, in terms of size and diameter.

The function of a elbow is to change direction or flow in a piping system. 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.

Applications :

• 45 degree elbow find frequent applications 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

90 degree elbow, also called "90 bends or 90 ells", are manufactured as SR (Short Radius) elbows and LR (Long Radius) elbows. SR (Short Radius) elbows have a Center-to-Face dimension of 1.0 X diameter and are typically used in tight areas where clearances are an issue. LR (Long Radius) elbows have a Center-to-Face dimension of 1.5 X diameter and are the more common type and used when space is available and flow is more critical.

A 90 degree elbow attaches readily to plastic, copper, cast iron, steel and lead. It can also attach to rubber with stainless steel clamps. Available in many materials like silicon, rubber compounds, galvanized steel etc, they connect rigid or IMC circuit together to allow for 90 degree bends.

This is a fitting device which is bent in such a way to produce 90 degree change in the direction of flow of the content in the pipe. An Elbow is used to change the direction in piping and is also sometimes called a "quarter bend".

Features
The main application area 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.

The function of a elbow is to change direction or flow in a piping system. 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.

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.

 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.

• Elbow 90°- 2"- LR : = 1½ x (25,4 x 2) A = 76,2 mm
• Elbow 180°- 2"- LR : = 1½ x (25,4 x 2) x 2 A = 152,4 mm
• Elbow 90°- 2"- SR : = 25,4 x 2 A = 50,8 mm
• Elbow 180°- 2"- SR : = (25,4 x 2) x 2 A = 101,6 mm
