Frequently Asked Questions
Can the DK6 Series Electric Tapping Machine tap pressurized pipelines without stopping flow?
Yes — this is a hot-tapping (pressurized drilling) machine. It mounts onto a saddle or split-tee fitting and drills a branch opening while the main line remains in service. Pipeline owners avoid supply interruption, flushing, and shutdown costs.
What pipe diameter range does the DK6 Series Electric Tapping Machine support?
The DK6 Series Electric Tapping Machine covers DN80 to DN600, with 6 model configurations to match specific main-line and branch sizes. It is suited to ductile iron, PE (HDPE), carbon and galvanized steel, and self-stressed concrete.
What power supply is required to operate the machine?
Models in this series are available in 380V three-phase and 220V single-phase versions. Variable-speed configurations (model suffix "C") are offered for operators needing fine feed-rate control in harder pipe materials.
Which pipe materials can this machine tap?
Engineered for ductile iron, PE (HDPE), carbon and galvanized steel, and self-stressed concrete. Drill bits and hole saws are selected per pipe wall material and thickness; PipeKnot provides a selection table for matching consumables to the target pipe.
What is the lead time and how is it shipped?
Standard lead time is 15 working days ex-factory, shipping FOB Shanghai. Sea, air, and combined transport are arranged through PipeKnot to over 40 countries. Volume orders and project tenders receive priority scheduling.
Is installation guidance and technical support included?
PipeKnot provides English-language installation drawings, torque specifications, and remote technical support. On-site commissioning support can be arranged for qualifying projects in partnership with Anhui Tongfa field engineers.
