![]() Galvanized pipe fittings should not be used with gas applications.īlack pipe fittings (black malleable iron fittings) are used to make connections to black iron pipe. The main advantage of using galvanized fittings is their superior rust resistance when compared to black and copper fittings. While they work best with cold water lines, they may be used with hot water as well. Galvanized pipe and fittings may be used in most applications with the exception of underground lines. Galvanized pipe fittings are used for countless outdoor and industrial applications because of the material's ability to protect against corrosion and salt. Galvanized pipe is mainly used for carrying water to supply home and commercial buildings it may also serve as scaffolding frames because of its rust prevention. Galvanized pipe fittings are covered with a layer of zinc which makes these fittings have higher ability of corrosion protection and help to prevent the accumulation of mineral deposits that will block the pipe. For transportation, black steel pipe tend to erode more easily than galvanized pipe and therefore it is more suitable for transporting gas and galvanized pipe is fit for carrying water instead of gas. As a result galvanized pipe is more durable. Both black steel pipe and galvanized pipe are made of steel, however, galvanized pipe has a zinc coating while black pipe does not. We even have third 150# steel flanges.Black steel pipe fittings and galvanized steel pipe fittings are the two most common kind of pipe applied to transport liquid and gas. The flanges come in blind, raised face, or threaded shapes. The flanges have a welded neck and come in A105 forged steel or forged steel. You can also choose between the 52 blind, slip-on, and threaded flanges we offer. ![]() These magnetic plugs attract and hold abrasive, ferrous metal particles, so they do not circulate through the lubrication or hydraulic system. The sizes are also taper tapped at ¾ per foot on the diameter Steel Magnetic Plugsīlackhawk Supply has four NPT threaded, magnetic drain plugs. We phosphate all twelve of our black steel API couplings. Our API couplings pass the API 5L & 5B standards.

They have a Schedule 160 rating with a diameter between ½ to 1-inch. If Schedule80 steel is not enough, then check out the 27 extra heavy seamless nipples. The seamless nipple uses Schedule 80 steel for a little more protection than a standard Schedule 40 nipple. The 188 extra heavy nipples SCH80 have sizes between ¼ - 4-inch diameter. The black and galvanized steel pipe fittings come in a variety of shapes including: Most of the fittings except many of the caps plugs have a Schedule 150# rating due to their thickness. You can choose the different materials for the pipe fittings including: Pipe Fittingsīlackhawk Supply offers 884 unique pipe fittings. The steel tote trays organize between 27 to 77 pieces that range from ½ to 2-inch nipples. You can also choose to get one of our steel nipple assortments that come with 60-66 nipples per assortment.
