How to make a simple cut into a steel pipe

In plumbing, and even in household practice, there are often cases when it is necessary to connect to a pipe and drain water. Let's say, to connect a washing machine. To do this, they usually pull a water pipe or hose to the distribution manifold, or saw the pipe and install a tee.
In old Soviet houses, the pipes are so inconveniently and clumsily laid out that connecting to them is tantamount to having to rebuild the entire system again.
But there is a way out! You can make a tie-in with a clamp into any nearby highway. So, more details...

How to make a simple cut into a steel pipe with your own hands

What will you need?

• Drainage (inset) - 1 pc.
  

It can be bought at plumbing stores, but before doing so, be sure to check what kind of pipe you have to which the connection will be made. I took 1/2 inch.
Here's what it looks like:

Now let's move on to the connection. First of all, we close the riser and drain the water.
Then we drill a hole with a metal drill. The diameter of the hole must be equal to or less than the diameter of the insert.

Next, use sandpaper to sand the area where the clamp will be put on.The surface must be smooth, free of old paint and rust. We put on the insert clamp, before installing the sealed gasket that comes with the insert.

Next, carefully tighten the 4 mortise bolts. You need to twist it carefully, alternately, preferably crosswise. This is necessary so that the gasket fits better and the clamp itself does not warp.
The insert is ready. We connect the required hose to it.

Turn it on and check the tightness. To do this, I recommend using a paper napkin or toilet paper, because the drops are immediately visible on it, but your hand may simply not feel it all.

Also, after the insertion, it would be a good idea to install a tap before connecting the hose.

In general, such an insert will help you out in seemingly the most hopeless situations.

The connection can be used for both cold and hot water. In addition, this is a very fast method and sometimes the only possible one.
