When making furniture from black steel pipe and fittings it should be noted that despite the light oil coating you may need to clean and seal with finish that suits the purpose. A new coating of Linseed oil is applied to items of furniture once manufactured. It has an oiled finish that protects it from corrosion for some time when used in furniture. The oil and petroleum industries use black steel pipe for moving large quantities of oil through remote areas. This pipe is not used for drinking water but black steel pipe’s strength makes it ideal for transporting water and gas in rural and urban areas and for conduits that protect electrical wiring and for delivering high pressure steam and air. It’s used in applications that don’t require galvanized steel. Its name comes from the scaly, dark-colored iron oxide coating on its surface. The black steel finish of these plumbing pipe fittings is created in a process in manufacturing of this pipe fitting after casting. These pipe fittings have a 1/2″ BSPT thread. Use this fitting to create your plumbing pipe construction tables, chairs, shelving, door handles, or any other project. The raw cast iron surface texture of this 90 degree bend shows in perfect detail since there is no zinc or gal coating. Use these fittings to create your plumbing pipe construction tables, chairs, shelving, door handles, or any other project. Previously only available as special order from the USA or China, we now have large stocks in the warehouse in Melbourne, Australia.īlack steel plumbing pipe fittings and pipe are the perfect industrial fittings to go with your industrial themed bar, cafe, restaurant or home. We have recently secured a range of black steel plumbing pipe and fittings in 1/2″, 3/4″ and 1″ BSPT threads to use in the construction of furniture and shelving. There are steel pipe and round hollow structural steel (HSS) grades available for use in non-piping (structural) applications which are identical in dimensions to pressure pipe, but which use much less reliable "furnace welding" or other means to form the long seam, so you do have to be careful making assumptions about spec/grade based on dimensions alone.Black steel plumbing pipe fittings are now stocked in Melbourne Australia. Steel pipe here for pressure applications is typically A53 welded (or sometimes seamless) or A106 seamless. I do know what centrifugally cast iron pipe is, and it is still used in drainage applications, but it is NOT joined by threading. I've never heard of "black iron pipe" before, and suspect that it is a misuse of the "black iron" description of non-galvanized black malleable iron fittings, misapplied to the pipe which is STEEL I am unaware of an ASTM designation for anything called "black iron pipe". That link that John R Baker posted is very confusing. These fittings are also made in cast stainless steels such as CF8 (304) and CF8M (316).ģ000# threaded fittings are generally A105 carbon steel forgings, not castings.ģ00# malleable iron fittings do exist, and just to make confusion more likely, they have dimensions very similar to 3000# forged steel fittings. If you find a 150# threaded fitting which sticks to a magnet, it is almost certain to be malleable iron, whether it is galvanized or black (not galvanized). Gray cast iron threaded fittings in small sizes (1/2-2") are no longer available, or if they are, they're rare enough that I've never seen one in the ~ 25 yrs I've been dealing with fittings on a daily basis.
