ANVIL 3 IN THREADED STAINLESS STEEL FLOOR FLANGE

Class 150 threaded flanges connect with low-pressure (100-299 psi) pipe and fittings. Threaded flanges, also called screwed flanges, include threads inside the flange bore which connects to the external threads on a pipe without welding. Threaded pipe flanges typically have a raised, flat, or RTJ (ring-type joint) face. Threaded connections include NPT (National Pipe Thread) or BSPT (British Standard Pipe Taper). Type 304 stainless steel, a chromium-nickel material, resists corrosion caused by water, heat, saltwater, acids, minerals, and peaty soils. Type 316 stainless steel has a higher nickel content than 304 stainless, plus molybdenum, for even greater corrosion resistance.
