M6-M100, 304/316L, 1m/2m Length Stainless Steel Welding Nipple
►Products Description
Weld nipples are fittings designed to connect tube systems, ideal for environments with extreme vibration, pressure surges, and temperature fluctuations. Made from stainless steel, they are commonly used in low to medium pressure applications such as steel plants, chemical industries, and shipyards. A weld nipple features male pipe threads at both ends and a plain section for welding to vessels or tubes. They are particularly useful for connecting pipes and valves where leakage must be avoided and disassembly is unnecessary. Their robust design ensures reliable performance in low-pressure piping systems, making them a versatile and durable solution for industrial applications
