Brass pipes of iron-pipe sizes are made in stock lengths of 12 feet, although special lengths can be had to order. The lengths are seamless drawn, can be had plain, polished, or nickel-plated and tempered hard, soft or medium; the medium temper, sometimes called regular temper, is just sufficiently annealed to make it suitable for

Extra strong pipe is always shipped without threads or couplings, unless otherwise specified.

Plumbing and steam work. Seamless brass pipes of iron pipe sizes are not made larger than 6 inches in diameter. Up to that size they may be had in standard and extra heavy weights, which correspond in safe working pressures with standard and extra heavy wrought pipes.

Brass fittings should correspond in finish with the pipes they join. The fittings are similar in pattern to beaded malleable iron fittings.

Iron Pipe Fittings

Threaded fittings for small sizes of wrought iron pipes are usually made of malleable iron, and have a bead cast around the outlets to strengthen them and prevent their splitting when being screwed on a pipe. For the larger sizes of wrought pipes, cast iron fittings, similar to those used for steam fittings, are generally used.
