Schedule 40 Black Steel Pipe

The Value Brand 587-360GR is a Schedule 40 black steel pipe designed for plumbing installations requiring threaded connections on both ends. It suits professionals and DIYers assembling gas, water or steam lines that demand a welded, standard-weight conduit.

Pressure Ratings and Thermal Limits

Rated for 150 psi at 150 degrees F and 1064 psi working steam pressure at 650 degrees F, the pipe handles typical residential and light commercial loads without excessive stress. Electric resistance weld construction and 9/64 in wall thickness contribute to consistent performance under pressure cycling.

Threaded Ends and Dimensional Fit

Each 3 ft length arrives with MNPT threads on both ends, allowing direct coupling to standard fittings without additional preparation. The 1 1/2 in nominal size yields a 1 39/64 in inside diameter and 1 57/64 in outside diameter, fitting existing Schedule 40 networks while meeting ASTM A-53, A-733 and Federal Specification WWN 351.

Questions about this item

How do I install the 1-1/2" MNPT threaded ends, and what step do people often get wrong?

Apply thread sealant to the male NPT threads and hand-tighten before using a pipe wrench; the common mistake is over-tightening, which can crack the Schedule 40 fitting.

What maintenance or replacement will this black steel pipe need later?

Inspect for internal corrosion or scale buildup periodically; replacement is required if the 9/64 in wall thickness is reduced or if leaks appear at the threaded joints.

What limit appears first under sustained use at high temperature?

The 150 psi pressure rating at 150 Degrees F is the limiting factor for continuous water service; steam service allows 1064 psi WSP at 650 Degrees F.
