Welding of the pressure lead tube for high-temperature and high-pressure medium transmitters
Thread Content
Are there masters familiar with this craft? Is it to make a hole directly in the high-temperature and high-pressure pipe and then weld in the pressure tapping pipe? Is it still necessary to make a hole first, then weld a pipe seat at that hole, and subsequently weld the short pipe along with the primary and secondary doors?
The pressures of the high-pressure tubes I have worked with were all of the second type
High-temperature and high-pressure branch connections generally use branch connection fittings. That is what you mean by the socket. There are requirements regarding the pipe diameter for directly opening holes and welding branch pipes.
We weld by making direct holes. Main pipe DN125, pressure lead pipe DN15, design pressure 10MPa

Generally, a welded pipe manifold with openings is used, and the pressure introduction pipes are welded at the manifold connections
