How to calculate the middle size when two 45-degree elbows are connected to the horizontal pipe?

Calculation method of the middle short pipe of two 45-degree elbows: short-circuit length = height difference x 1.4 142-0.8284R, and R= bending radius of elbows (that is, the length of 90-degree elbows).

The minimum relative bending radius of pipe is an important technological index to judge the bending degree of pipe, which can represent the bending forming limit constrained by many forming defects in actual elbow production.

New project

1, applied to the newly-built water plant of Yellow River Water Plant in Bayannaoer City, Inner Mongolia, with a daily output of 654.38+10,000 tons, which solved the problems of high turbidity of raw water in summer and low temperature and turbidity in winter;

2. It has been applied to the Chengbei Sewage Treatment Plant of Xicheng, Dongying City, Shandong Province, with a daily treatment capacity of 40,000 tons. The effluent reaches the first-class A standard of pollutant discharge in urban sewage treatment plant and is used for urban reclaimed water reuse;

3. It is applied to Heiliuzi Water Purification Plant in Urad Qianqi Industrial Park, Inner Mongolia, with a daily output of 50,000 tons of industrial water;

4. It was applied to the water purification plant of Inner Mongolia Hetao Water Hengyuan Water Supply Company, which solved the problems of high turbidity in summer and low temperature and low turbidity in winter.

modification works

1, which was applied to the renovation of Huaiyin Water Supply Company in Huai 'an City, Jiangsu Province. The water volume increased by 1.8 times, and the turbidity of the effluent reached the new national standard.

2. It was applied to the reconstruction of Dayu Water Plant in Dingyuan County, Anhui Province, saving the overall investment cost and stabilizing the turbidity of the effluent;

3. It has been applied to the reconstruction of Laohetai Water Plant in Huludao City, Liaoning Province, with the water supply capacity reaching 65,000 tons/day and the turbidity of effluent from sedimentation tank being lower than 3NTU.
