How did you choose the chemical hose? What factors are generally taken into account? Let’s discover that.

Chemical compatibility:

When transporting different fluids, the hose should show certain excellent chemical properties, which is called chemical compatibility.

Such as: low adsorption, good temperature resistance, not easy to aging, no swelling, corrosion resistance, low precipitation. Chemical compatibility see Chemical Compatibility Table.

Chemical compatibility table specially developed for pump pipes should be used, not those developed for common pipes.

Ordinary pipes only have general contact with chemical substances. But the peristaltic pump pipes are in contact with chemical fluids under pressure conditions. So the chemical compatibility level of ordinary pipes and it cannot be equal to that of peristaltic pump pipes.

When referring to the Chemical Compatibility Table, each component of the solution, not only the main component, should be checked for compatibility with the pipe to be used.

Some acids or solvents in contact with the pump line for hours or days, even trace, will cause sufficient damage to the pump line. The user should check each chemical in the solution to ensure that it is compatible with the selected pump line.

Chemical corrosion resistance:

The chemical corrosion resistance of the hose decreases with the increase of temperature. Chemicals that do not affect the hose at room temperature may affect the hose with the increase of temperature. The hose should show good chemical properties when transporting different fluids.
