The length of a 90-degree elbow with a long radius can be calculated using the following formula: Elbow Length = π × Diameter × Bend Radius / 180 Where π is 3.14, the diameter is the nominal diameter, and the bend radius is the distance from the center line of the elbow to the end face.
The length of a 90-degree long radius elbow can be calculated using the following formula: Elbow Length = π × Diameter × Bend Radius / 180 where π is approximately 3.14, the diameter is the nominal diameter, and the bend radius is the distance from the center line of the elbow to the end face. For a 90-degree long radius elbow, the bend radius is the distance from the center line of the elbow to the end face, which is the long radius. Therefore, the formula for calculating the length of a 90-degree long radius elbow is: Elbow Length = 3.14 × Nominal Diameter × Long Radius / 180 It should be noted that the nominal diameter here refers to the diameter of the elbow connection, and the long radius refers to the straight-line distance between the two ports of the elbow. In practical applications, the required elbow size and type should be determined according to the specific piping system and design requirements. At the same time, if precise calculation is required, factors such as pipe wall thickness and material should also be considered.
Large-diameter butt-weld flanges have poor rigidity and are suitable for occasions with pressure p≤4MPa; weld neck flanges, also known as high-neck flanges, have high rigidity and are suitable for occasions with high pressure and temperature. There are three types of flange sealing surfaces: flat sealing surface, suitable for low pressure; concave-convex sealing surface, suitable for slightly higher pressure; tongue and groove sealing surface, suitable for flammable, explosive, toxic media and higher pressure occasions. Flanges of different properties have good product performance in different fields, adapt to different occasions and spaces, and produce different effects.
