Tubing testing guides

Release Time:2015-12-19

Immersion test will be needed, when the chemical compatibility of the tubing is uncertain. In this test, weighed a small piece of tubing and measured its length and diameter. afterward immersed this tubing in specific liquid contained in an airtight vessel for minimum 48 hours, then record any changes to the tubing after it was rinsed and dried and measured. The softening, embrittlements or color changes of tubing mean the tubing had been affected by the specific liquid.

The tubing is compatible with the specific liquid if it survives through the test without discoloration, swelling, cracking, loss of flow or other signs of deterioration.
