High Temperature resistant fire sleeve widely serves in petrochemical industry
Recently, a customer asked what is the reason for the bad adhesion between the two hoses of the twin welding hose? And how can it be improved? So, here’s the answer.
- Reason of bad adhesion
- The temperature of the mold machine is not enough
The temperature of the mold machine has not reached a certain temperature, so the adhesive effect of the hose is not good enough.
- Uneven hoselength
When the hose is covered with the outer adhesive layer of the welding hose, the adhesion effect is not good due to the uneven feeding length
- The fixture is too loose
The clamp that squeezes the tubes together is not tight enough, resulting in poor adhesion.
(II) Three ways of improvement
- Increase the temperature of the mold temperature machine
Increase the temperature of the mold temperature machine, so that the material is skilled to increase the degree of adhesion before the two hoses.
- Feeding is uniform
When making the outer adhesive layer of the hose, make the feeding hose even, so that one hose is not long and the other one is short, because if the feeding of the hose is not uniform, one hose is too long, then the hose will sag and affect the adhesion of the hose.
- Adjust the fixture distance
Adjust the distance of the clamp to make the distance between the two hoses more compact.
The above is the reason for the bad adhesion between the two hoses of the twin welding hose and the improvement method. When buying the hose, we should choose carefully. It is best to choose the regular manufacturer, so that the quality is more guaranteed.
