The set is designated for the drilling of openings to pipelines made of steel or PE with internal positive media pressure using ballooning adapter with an outer thread 2 ½ “ and ball closure. This set is configured as an accessory system to ballooning sets and therefore, the ball closure is not included. The set is supplied with basic accessories as specified below in the set content description.
APPLICATION AND DESCRIPTION
The KNS-F1 devices are chamber drilling systems used for the drilling of openings into pipelines with inner media positive pressure including but not limited to the following applications:
- temporary ballooning set pipeline closing through a drilled-in adapting piece and a closing fitting
- temporary closing of the pipeline by manually inserted balloons
- branch line drilling using drilling T-pieces
The steel drilling rod gets through a chamber provided with sealing elements. Its working section is adapted for the fixing of the drilling bit and the centering bore and the control section provided with a square ending that makes it possible for manual or machine driven drilling. The thrust arm ensures the axial shift and guiding of the drilling rod and its safe retraction after the drilling of the opening.
The KNS-F1 device may be delivered as a standard supply in the below described customized sets as may be required by the customers.

RANGE OF APPLICATION
Pipeline drilled diameter: no limit
Drilled opening diameter:
8 - 57 mm for steel pipes
8 - 56 mm PE pipes
Drilled pipe material:
This depends on the used drilling bit and drilled material properties (metal, plastic, asbestos-concrete etc.)
Media:
Natural gas, water, non-aggressive gases or liquids.
Other media should be consulted with the manufacturer.
Maximal pressure in the drilled pipeline: up to 10 bar *
Working temperature:: -50/+70°C **
* The maximum permitted positive pressure when drilling based on the type and set outfit.
** The bottom limit may be limited depending on measures taken to prevent freezing of condensate in the air system when using a compressed air motor drive, the upper limit may be increased based on consultation with the manufacturer.
