ASTM A53 Schedule 40 carbon steel pipe nipples are available in seamless or welded types, with black or galvanized finishes for corrosion resistance. Designed with male threaded ends, they provide secure connections in steam, water, gas, and air pipelines, widely used in plumbing, industrial, and construction systems.
ASTM A53 Schedule 40 pipe nipples are made from carbon steel with a wall thickness defined by the Schedule 40 standard. These pipe nipples can be manufactured from either seamless or welded pipe fittings, offering reliable performance in a wide range of mechanical and pressure applications. They are commonly used in steam, water, gas, and air lines, and are suitable for welding, coiling, bending, and flanging operations.
To enhance corrosion resistance, the surface can be finished in black (black oxide coating / black sandblasted) or hot-dip galvanized.
A threaded pipe nipple is a short piece of pipe with male threads on both ends, designed to connect two female-threaded fittings or equipment. Also known as a barrel nipple or plumbing nipple, they are widely used for extending pipe lengths or connecting threaded components of the same diameter.
