DRILLING

Drilling holes or ‘thread tapping’ on site i.e.: building sites, shipyards, constructions and installations. Drilling up till 150 diameter, is possible with the use of a portable magnetic drill.

Holes can be drilled either straight or at a desired angle in pipelines, apparatus or constructions in every desired diameter. Holes can be drilled either straight or at a desired angle in pipelines, apparatus or constructions in every desired diameter. Holes in machinery can be achieved with a line-drill.

Hottap

A hot tap is the drilling of a hole in pipelines, tanks or installations that are in operation (pressurized).

Because we drill through closable flanged valves that remains in place after drilling, placing a branch or fitting can be achieved without taking the system offline. Due to the hot tap equipment being a sealed unit, product cannot be released into the environment.

Hot taps can be carried out on systems containing gasses or fluid products. Drilling is carried out with the use of a ‘hole cutter’ with a ‘pilot drill.’ Within this pilot drill a special device is incorporated to retain or remove the coupon from the pipeline or equipment.

Through a partnership with de Vin-Pass, we have equipment available to drill up till 24″(NW600), up till a maximum pressure of 80 bar 20°C.

Coldtap

A Cold tap is the drilling of a hole in pipelines, tanks or installations that are in operation (pressurized).

This is achieved through the use of magnetic drilling machines. Special ‘hole cutters’ equipped with a pilot drill are used for this process.

Within this pilot drill, a special device is incorporated to retain or remove the coupon from the pipeline or equipment.
