Working Principle
Physical Extension
The extension tube connects via threaded joints to physically extend the discharge path downward, allowing fluid to flow out under gravity.
Sealed Connection
The mechanical force generated by tightening the threads compresses the sealing gasket, effectively preventing any liquid leakage from the connection interface.
Applications
Dispensing Operations
Used for transferring liquids from IBC tanks into smaller containers (such as 20L or 25L drums). The extension tube can reach inside the container opening, helping prevent splashing and spillage.
Low-Level Connection
When the IBC tank is placed on a pallet and the receiving pipeline is at a lower position, the DN50 Extension nozzle helps compensate for the height difference.
Chemical Dosing
In electroplating and water treatment industries, it is used for directly dosing chemicals into reaction tanks with lower liquid levels.
Anti-Drip Function
The extended tube helps stabilize the liquid flow, reducing wall adhesion and dripping after valve closure.
