Welker Adjustable Probe with Injection Nozzle AP-3MI
Probes

The Welker Adjustable Probe with the injection nozzle (AP-3MI) is designed to insert the chemical injection nozzle into a low pressure pipeline (500 max. psi). For pipeline pigging or for service on the nozzle, the unit can be quickly withdrawn without pipeline operation interruption. The nozzle will disperse the chemical in a more efficient manner than the typical straight tube. The Welker AP-3MI can be used with any chemical injection system. For proper sizing of the nozzle, estimated injection rates should be provided to Welker. The AP-3MI can be inserted through a 1” full open ball valve. A number of nozzle styles are available and can be sized to meet your specific needs. Line pressure, pump pressure and your gpm needs will assure correct nozzle for the application. Specify insertion length (18” - standard).

Probes

The Welker Automatic Insertion Probe is designed for use in pipelines and systems where it is required to insert and retract a probe while the pipeline remains pressurised.

 

The Automatic Insertion feature allows the operator to control the movement of the probe in and out of the pipeline safely, through the use of 3 hand control valves. The AIP-1 and AIP-2 probes are hydraulically operated, all probes are designed to utilise pipeline pressure for the motivating medium Therefore no manual force is needed and any line pressure up to the rating of the probe may be accommodated.

 

Probes are available with a range of tube sizes and travels. Travel lengths are field adjustable up to the maximum insertion length.

 

The AIPP probes feature a return port for a 'Hot Loop' return for the gas. Construction of the probes is all 316 st.st. With Viton, PTFE and Fluorotrel elastomers.
