Product Description

The Anvil 325 schedule 80 extra-heavy seamless nipple pipe fitting is made of steel with a black finish and has male National Pipe Taper (NPT) threaded connections. This seamless nipple fitting is a length of pipe with threaded ends for connecting threaded pipes. Seamless pipe is produced from a solid piece of metal that is heated and moved over a form until the steel is shaped into a hollow tube. It can withstand pressure better than ductile or welded pipes. It has male NPT threads for connecting to female threaded pipes, creating a tighter seal than straight threads. This schedule 80 (thick wall) fitting is made of steel for weldability and greater rust resistance than iron, and it has a black finish for increased resistance to corrosion in oil and gas applications. This schedule 80 fitting has a thicker wall and is more rigid than a schedule 40 fitting, and is extra heavy for use in heavy-duty applications. This fitting meets American Society for Testing and Materials (ASTM) A733 and A106 for grade B seamless pipe.

Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size, and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).

Anvil International provides pipe products and design services. The company, founded in 1850 and headquartered in Portsmouth, NH, meets International Organization for Standardization (ISO) 9001:2000 standards and is certified by the American Petroleum Institute (API). Its fittings meet American Society for Testing and Materials (ASTM) and American Society of Mechanical Engineers (ASME) specifications.
