Yes, if it's big enough to worry about leakage, pressure test it in 
segments as you go.

You can find some truly amazing threads in some of the iron pipe 
fittings in the stores these days.

When I did the plumbing on our house a few years back, I didn't have a 
pipe threader (the water and compressed air piping is copper, but the 
gas is iron.)

Fortunately OSH is only three minutes away.

Unfortunately the guy out back running the pipe threader was new and had 
no clue what he was doing.

Fortunately, he responded well to suggestions.
