What are theTypes of Nipple?
A nipple is a short pipe with external threads at both ends, used to connect two internally threaded fittings, valves, or equipment. In addition to the conventional round tube section (Barrel Nipple), the hexagonal tube section (Hex Nipple) is designed with a hexagonal cross-section in the middle. This hexagonal section provides a convenient clamping point for using a wrench during installation, making it easier to apply torque and achieve a tighter and more reliable sealed connection.

BSP Threaded Connection
This pipe fitting adopts BSP (British Standard Pipe Thread), which is a widely used thread standard in Europe, the Commonwealth, and many regions around the world. Its 55 ° tooth profile angle design can be connected through taper threads (BSPT) or parallel threads (BSPP). Threaded connections do not require on-site welding, making installation and disassembly very convenient. They are a highly cost-effective and flexible connection solution in low-pressure piping systems.

How to Choose Fitting Material: 304 vs. 316?
The choice between 304 or 316 stainless steel mainly depends on the corrosiveness of the usage environment. 304 is a highly cost-effective universal choice, suitable for most conventional environments such as water and air. When the pipeline needs to come into contact with more corrosive media, such as seawater, salt spray environment, or some chemical liquids, 316 should be selected. 316 material has stronger resistance to chloride corrosion and pitting corrosion due to the presence of molybdenum element, providing longer service life and higher reliability.

Application of Casting Nipple
The Class 150 hexagonal pipe joint is the basic component for assembling threaded connections to low-pressure pipelines. The small diameter design of 1/2 inch makes it commonly used for connecting instruments, valves, filters, and small equipment. 316 material makes it suitable not only for conventional water supply and drainage systems, but also for industrial pipelines, ship pipelines, and chemical public works with certain corrosiveness. It is a widely used and easy to install connector.
