3/4 in. Female NPT Threaded - Weld Spud - 150# Cast 316 Stainless Steel Pipe Fitting

Weld Spuds - 150# NPT Threaded 316 Stainless Steel Pipe Fittings - Cast

Class 150# stainless steel 304 and 316 cast pipe fitting reducing couplings with female National Pipe Taper (NPT) threads for connecting two sections of male pipe or fittings. National Pipe Taper (NPT) threads for creating tighter seals than straight threads. The "weld spud" design means one end is welded to a pipe, tank, or vessel, providing a permanent and robust connection. This is stronger than bolted connections and ideal for high-integrity seals. This weld spud is used to create a strong, corrosion-resistant, threaded connection point by welding it to a pipe or vessel, primarily in low-pressure systems across industries like brewing, chemical processing, and marine applications.

Common Applications:

Brewing and Food Processing: Often welded to kettles or tanks (e.g., brew kettles) to attach valves or other fittings for draining or controlling flow. Users note its durability when welded to thin stainless steel sheets without warping.

Chemical and Pharmaceutical Industries: Used in systems handling corrosive substances due to 316 stainless steel’s superior resistance compared to 304 stainless steel.

Marine Applications: Ideal for environments exposed to saltwater because of its corrosion resistance.

Industrial Piping: Employed in low-pressure piping systems for air, water, oil, or natural gas, where a secure welded connection is needed.

Custom Fabrication: Welded to vessels or equipment to provide a threaded port for attaching components like gauges, valves, or hoses.
