The American National Standards Institute (ANSI) assigns "schedule numbers" to classify wall thicknesses for different pressure uses. ANSI schedule numbers cover all pipe sizes from NPS 1/8 through NPS 36 identified as Standard (STD), Extra Strong (XS) and Double Extra Strong (XXS) and all wall thicknesses by ANSI schedule number. Choices include 5S, 10S, 40S, 80S, 10, 20, 30, 40, 60, 80, 100, 120, 140, 160, STD, XS, XXS, SDR 13.5, SDR 21, SDR 26, SDR 41. Products & Services
Industrial pipe is a broad category of fluid and solid transport hardware used in many applications and industries. Cylindrical pipe and rigid tube is used in process, energy, construction, and civil infrastructure applications.
Pipe fittings include many components that connect pipe ends for in-line, offset, multi-port, and mounting configurations.
Guardrails and railings are used as fall protection systems or to establish controlled access zones.
Pipe hangers and pipe supports include clevis hangers, beam clamps, pipe clamps, brackets, pipe straps and other accessories that hold pipes in place.
Ladders are devices that workers use to step up or gain access to elevated surfaces.
