Hot Tapping And Line Plugging Techniqes

Hot /Wet / Cold / Tapping…. HOW IT WORKS

Tapping is a precise process of drilling a hole in an on-stream piping system without spilling its contents or interrupting its flow. Over the years HENMAK Technical Services Ltd have successfully performed hundreds of hot taps on and offshore and in nearly every type of pipeline material.
Piping systems are designed to move liquids, gases or other products in a continuous flow. Shutting down these essential systems or even portions of them can be extremely costly and time consuming. When alterations or repairs are required in live line systems, HENMAK Technical Services Ltd will handle your assignments from concept to completion, whether the operation calls for common taps, side taps, angle taps or tank taps.

Typical HENMAK hot tapping procedure.

A fitting is permanently secured to the line.
A permanent valve is installed on the fitting.
A hot tapping machine is installed on the fitting and the valve is opened. After pilot drill penetrates the tapping machine fills with product, and air is purged from the housing. The tap is made through the line and the coupon is retained.
The valve is closed, and the tapping machine is removed. A branch connection is added, and the valve opened. The new connection is ready to put into service. This field-proven HENMAK procedure is quick and precise
