Attentions:

1.Be careful when the ambient temperature or the fiuid temperature is over 60℃, hightemperature will cause the tube with problem of aging crack.

2. Be careful when the ambient or the fluid is with the strong corrosivity such as strong acid, strong base and strong solvent, the possibilty of the tube explosion exists in the severe corrosion environment.

3. Long time storage in thehumid environment will cause the tubes cracking because of the hydrolysis.
