Pressurized pipeline tapping
Thread Content
There is a circulating water makeup pipe, and we plan to find someone on the ground to make a hole under pressure in order to run a pipeline out. The temperature of the circulating water make-up pipe is at room temperature, with a pressure of 4.5 kilograms. Prepare to introduce a DN80 pipe. I’d like to ask what the price for making openings is roughly; I have an idea of it as well.
Hire a professional company specialized in plugging leaks under pressure; the budget is around 20,000 yuan.
Thin tubes can be handled by hand, but if the tube diameter is too large, tools are needed. First, weld a short circuit and connect a ball valve. Then open the valve fully and insert the drill bit to start drilling. Put a rubber water-blocking ring on the drill pipe. Drill through and close the drill valve. ，，，，。 It is best to make a short drill bit tip by oneself, with a drill shaft connected to its back, which can reduce the amount of water sprayed out.
This company is really unfair – they charge 20,000 yuan just for making a pressure-hole in a DN80 pipe. I think two thousand is too much already.

This kind of work really doesn’t need to be done by hand; any construction company can handle it. Two thousand for making an opening in a DN80 pipe under pressure is sufficient; it’s not about sealing the pipe under pressure
Thank you. I discussed it with someone, and 3500 is the price for making a hole
This task involves little difficulty and no risks, so the cost will not be high.
