There are many available types of pipe for the pipefitting trades. I’ve worked with all of them. From black steel to blue brute underground piping, you name it and I’ve installed it at one time or another around the Los Angeles area. While you may think if you have seen one type of pipe then you have seen them all, think again. The wrong pipe installed in the wrong location can spell financial and structural disaster in just a few short months.

Black Steel – the standby for sprinkler and gas lines. This type of pipe is available in varying wall thickness, called “schedule”. The standard thickness for black steel pipe is schedule 40, which is more than enough steel to allow for machine threading. Black Steel piping can never be used for water supply lines; it is used primarily for gas lines and for automatic fire protection systems.
