Can we weld two tubes together to meet the total length requirement? We have fire tube boiler operates at 12 bar pressure. The available tubes are short in length by a meter, therefore we intend to join two tubes together in a way to fit to the required size. If it is allowed by the code, what considerations one should keep in mind?

I'm not familiar enough with Section I to answer the question, but my guess is that this is likely allowed. Check with your A.I.
There is a false perception that anything that looks like a poor design practice is expressly prohibited by ASME Code, but the reality is that many things that would be considered a poor practice (e.g. nozzles located directly on weld seams, nozzles located in the knuckle region of a head, nozzle attached with partial penetration welds, vessels fabricated out of more individual plates than is absolutely necessary, repads overlapping weld seams, square/rectangular repads with sharp corners, repads thicker than the vessel wall thickness, etc.) are perfectly acceptable per ASME Section VIII.
