Detailed operation steps of the pneumatic pipe joint tensile test

Detailed procedure for tensile test of pneumatic pipe joints by tensile testing machine

Pneumatic pipe joints are quick joints for air piping and pneumatic tools. They can be connected without any tools and are very convenient to use. In order to ensure the connection of the pneumatic pipe joint, we must perform a tensile test on it and improve the connection stability by the obtained data. Let the technicians of Xintianhui share the following detailed steps for the tensile test of the pneumatic pipe joint using the tensile testing machine:

Step 1: Preparation of the pneumatic pipe joint sample: According to the preparation requirements of the standard test, a standard sample is prepared, and a plurality of samples can be selected for the tensile test.

Step 2: Start the tensile testing machine: turn on the instrument power switch, computer, test run tensile testing machine.

Step 3: New operation record: Create a new operation record, and add some relevant information of the test, such as operator, operation number, sample specification, stretching mode, test speed (speed should not be too fast, set 200mm/min here) Just wait).

Step 4: Install the sample: Install the pre-formed sample on the fixture of the tensile testing machine, and follow the principle of first going up and down.

Step 5: Start the test: Click the test start button and stop the test immediately if it is abnormal.

Step 6. End of test: After the test meets the standard requirements, it will automatically stop and record the data. It may take several more times to meet the standard requirements. The specific operation steps are the same as above.

Step 7. Organize the instrument: Firstly, turn off the power of the tensile testing machine and remove the accessories for future use.

Step 8. Organize the data: Print the data stored in the computer and compare it with the requirements of the pneumatic pipe joint production standard GB/T14514.1-2013.
