Threaded End Caps — Frequently Asked Questions
Threaded End Caps are solid pipe fittings with internal threads, used to seal off the end of a male-threaded pipe or a female-threaded fitting. Their primary function is to provide a secure and leak-proof termination for pipelines, preventing leakage, containing pressure, and protecting the pipe interior from contamination. They are widely used for temporary closures during maintenance, permanent sealing, or as a convenient point for future system expansion.
The primary standards governing Threaded End Caps include ASME B16.11 (Forged Fittings, Socket-Welding and Threaded), BS3799 (Specification for Steel Pipe Fittings, Screwed and Socket-Welding for the Petroleum Industry), and various MSS SP specifications like MSS SP-79, MSS SP-83, MSS SP-95, and MSS SP-97. These standards ensure dimensional accuracy, material compatibility, and pressure integrity for reliable connections.
Threaded End Caps are typically available in several pressure classes, including 2000 LBS, 3000 LBS, 6000 LBS, and 9000 LBS, indicating their maximum allowable working pressure. The nominal bore (NB) size range commonly spans from 1/8 inch to 4 inches. This range caters to a variety of light to heavy-duty industrial applications requiring robust threaded connections.
For Threaded End Caps, we offer common thread forms including: NPT (National Pipe Taper), which is the most common North American standard for tapered threads; BSPT (British Standard Pipe Taper), widely used outside North America and also tapered for a pressure-tight seal; and BSPP (British Standard Pipe Parallel), common in Europe, which uses a parallel thread and typically requires a gasket or O-ring for sealing. This ensures compatibility with diverse international piping systems.
