Tensile Tests for Low-Pressure Graded Pipes for Electricity Distribution Companies:

 Tensile Tests for Low-Pressure Graded Pipes for Electricity Distribution Companies:

- The column to be tested is installed horizontally at a distance of 1.2 meters from the base of the column (the depth of the column in the concrete base) and the column is carried at a distance of 30 cm from there.

The tensile test is carried out on 4 per thousand of the number of manufactured columns.

- The column is suddenly loaded until it reaches the design load for two minutes, and then suddenly drops according to the following values, after each model for the virtual test.

 - The column is loaded with a gradual increase of 50 kg or 100 kg until we reach the design load mentioned later multiplied by the safety factor according to each model, then the load is reduced at the same rate of gradual increase until it reaches zero and the deviation is calculated so that it is less than 5% of the maximum deviation of the maximum tension Column mechanism for each column is tested.

The design load for each column in the previous two tests, the apparent test, and the load test, is as follows:

Column model Two-minute sudden load (kg) Design load

(kg) Coefficient of safety Maximum tensile strength (kg)
