Embodiment 1
[0055] Example 1: Test the minimum storage bending radius of DN150 polyethylene pipe at room temperature
[0056] (1) Sample preparation: take a polyethylene pipe with a length of 1000mm as the test pipe sample;
[0057] (2) Pipe connection: connect the processed polyethylene pipe to the hydrostatic blasting tester;
[0058] (3) Place the sample: first select the appropriate clamping block according to the outer diameter of the test tube sample, and clamp the middle of the test tube sample in the clamp; adjust the height of the two adjustable fixed piles to ensure that the transmission rod is The center of the test tube sample is on the same horizontal line; according to the length and outer diameter of the test tube sample, determine the position of the fixing bolt and the sliding bolt to complete the clamping and fixing of the two ends of the test tube sample.
[0059] (4) Setting of the bending system: Set the distance between the two fixing bolts to the chord length, combine with ...
Embodiment 2
[0063] Example 2: Test the minimum working bending radius of DN100 flexible composite pipe at 50°C
[0064] (1) Sample preparation: take a flexible composite tube with a length of 1200mm as the test tube sample;
[0065] (2) Pipe connection: connect the processed flexible composite pipe to the hydrostatic blasting tester;
[0066] (3) Place the sample: first select the appropriate clamping block according to the outer diameter of the test tube sample, and clamp the middle of the test tube sample in the clamp; adjust the height of the two adjustable fixed piles to ensure that the transmission rod is The center of the test tube sample is on the same horizontal line; according to the length and outer diameter of the test tube sample, determine the position of the fixing bolt and the sliding bolt to complete the clamping and fixing of the two ends of the test tube sample.
[0067] (4) Setting of the bending system: Set the distance between the two fixing bolts as the chord length, and cal...
Embodiment 3
[0071] Example 3: Verify the minimum storage bending radius of DN150 polyethylene pipe under room temperature conditions
[0072] (1) Sample preparation: take a polyethylene pipe with a length of 1000mm as the test pipe sample;
