3 pipes (10m each, 96 inch diameter, 50mm wall thickness)

[pontuskamark]

How would you weld 3 pipes (10m each, 96 inch diameter, 50mm wall thickness) ?

What would be the sequence, tooling, alignement technique and measurements taken ?

Thanks

Butt welding to make a 30 m long pipe?

Or similar to portions of this?

Not enough information.

What material? What fluid?
What service (duty) and under what conditions?
(Pressure, temperature, fluid, vibration, outside stress, changes or vibration or Code ....)
What country are you in? What country is the installation going to be in?
What are your company's NDE requirements? PWHT requirements and standards? In the field, your shop, customer's shop, prefab'ed by somebody else?

We don't know enough to do anything that could even start to help you, and it is NOT SAFE for anyone to comment until you can define your parameters fully.
