high pressure hydraulic tube bending

[Emc2]

I would like to know if it is accepted to fold oil pipes with hydraulic bending machines (ercolina) during laying pipes, this because during laying stainless steel pipes for a rolling plant with pressures greater than 250 bar I have seen bending a couple of tube breaks in order to avoid the use of welding flanges (sae) to follow the path on the machine.

every client has his own connections.
generally yes, also because you are less and reduce the number of welds.
all this provided that the bending is done well and with sufficiently wide rays

the bending of pipes is performed with two types of machines: controlled electric ones and hydraulic ones with mechanical end-race feedback. Nothing changes. on both the fold wheels are fitted with rays suitable for the diameter of the pipe and the material to be folded. surely the technologies are many for the junction of the pipes:
- threaded
- weld directly
- welding flanging
- with printer that creates the cone 24° recalculating the tube + wreath
- cone to be mounted on smooth tube and double o-ring + wreath
