Class 150 Black-Coated Steel Pipe Flanges
30
products

Class 150 black iron and black steel pipe flanges are used in low pressure applications. Black iron and black steel pipe flanges are incredibly strong and resilient but susceptible to corrosion. Iron and steel both offer good thermal and electrical conductivity. Iron is a metal and steel is an alloy that mixes iron with carbon and other elements. Pipe flanges create an access point in a line for cleaning, inspection or modification.
