Black Iron Pipe Fittings
What are Black Iron Pipe Fittings?
Black pipe fittings are a kind of malleable iron pipe fittings or grooved pipe fittings,are made from corrosion-resistant ungalvanized steel with a scaly, black-colored iron oxide coating. Since there is no surface treatment, they are called black pipe fittings. Correspondingly, it is hot-dip galvanized pipe fittings, that is, galvanizing the surface of black pipe fittings to form a zinc layer of a certain thickness.
What are Black Iron Pipe Fittings advantages?
The two most common kinds of pipe fittings used to transport liquid and gas are black steel pipe fittings and galvanized steel pipe fittings. Despite the fact that galvanized and black steel pipes are both made of steel, galvanized pipe fittings are zinc-coated, while black steel pipe fittings are not. Galvanized pipes are therefore more durable. Due to its tendency to erode more easily, the black malleable iron pipe is more suitable to carry gas than galvanized pipe. Galvanized pipe, however, is intended to carry water rather than gas in transport applications. The black pipe fittings price is less than that of galvanized pipe fittings.
What are Black Iron Pipe Fittings used for?
Pipes and fittings with black iron are connected with black pipe fittings (black malleable iron fittings). The black iron pipe system transports natural gas to residential properties.
Due to its seamless construction, black steel pipe is better suited for gas transportation and fire sprinkler systems since it can prevent fire better than galvanized pipe. As a result of its heat resistance, the black iron pipe is often used in fire sprinkler systems as well as water supply lines to prevent water damage. During the manufacturing process, iron oxide forms a dark colour on its surface, giving the pipe the name black steel pipe.
On the other hand, black steel pipe is not suitable for water transportation. The black steel pipes tend to corrode in water and the minerals will dissolve in the water, clogging the line.
