Dosing Tube & Dosing Hose
We supply a range of dosing tube which is specifically for use with the transfer of chemical reagents in process control, water treatment or effluent treatment applications.
We strongly recommend that dosing hose is supplied as double confined dosing tube. This gives the dosing tube a secondary containment area as well as greater mechanical strength and UV shielding.
Our dosing tube can be supplied in single continuous lengths with a maximum length of 100 metres for 4x6mm and 8x12mm sizes and 50 metres for imperial sizes of 3/8" and greater.
Dosing Tube Chemical Compatibility
The dosing tube that we supply is designed specifically for the transfer of chemicals. Some materials are more chemically resistant than others, with LDPE offering good chemical resistance, PVDF offering greater chemical resistance and PTFE offering the greatest chemical resistance. (PTFE is chemically resistant to almost all reagents, excluding gold cyanide, amongst others.)
When specifying dosing tube and other wetted parts for use with chemical reagents, we strongly recommend checking the chemical resistance of the material that you're planning on using, with our chemical compatibility database.
Dosing Tube Operating Limits
To ensure that the dosing tube is operating within the prescribed limits we list the following parameters:-
- burst pressure,
- minimum operating temperature,
- maximum operating temperature,
- maximum bend diameter
- weight
If there is any information that you require relating to dosing tube, then please don't hesitate to get in touch with us.
