The three-way manufacturer stated that if the length of a 90 degree elbow needs to be calculated, it can be calculated according to the relevant formula, which is as follows:
The length of a 90 degree elbow is equal to the bending radius of a 90 degree elbow multiplied by half the degree of a 90 degree elbow, which means that the length of a 90 degree elbow is equal to the bending radius of a 90 degree elbow multiplied by 45 degrees. If the elbow is not standard, then the length of the elbow=bending radius x 0.707.
When purchasing elbows, it is recommended to keep the material, outer diameter, and thickness of the elbows the same.
2、 Issues to be paid attention to during the construction of 90 degree elbows
1. Before cutting the pipeline elbow, construction management personnel must make sure to determine whether the pipeline elbow has developed and been lifted, and also analyze to determine whether there are lifting bars on the straight pipes at both ends. If there is a suspension rod, it is necessary to determine whether the suspension rod is reliable,
If there is no suspension rod, the straight pipes at both ends need to be lifted with a hoist before they can be used. Usually, two cranes are needed to lift the pipe bends, which are both firm and will not cause any problems.
2. The three-way manufacturer stated that construction management personnel should conduct a detailed inspection of the 90 degree elbow for sand holes, air holes, and other phenomena before construction, and we should also carefully check whether the bending angle, outer diameter size, length, etc. of the lower pipeline elbow can be correct,
Make sure you don't have any problems before you can develop and start construction in the future.
3. To avoid injury to the 90 degree elbow, it is recommended that the pipeline elbow to be installed be placed on a wooden board or leather, and not directly on the ground.
