A Stainless Steel Hex threaded nipple is a commonly used pipe connector for connecting two male-threaded pipes with the same diameters. It has a hex between the two threaded ends for easy installation and removal. These stainless-steel threaded pipe nipples are an easy way to add length to existing or new pipe runs.
This kind of stainless steel male threaded nipple national pipe taper (NPT) threads on both ends for connecting female pipes. It creates a tighter seal than straight threads. The thread part adopts internationally accepted standards, such as BSP, PT, NPT, G, MF, etc., and can be customized according to needs.
Stainless steel has high corrosion resistance and versatility, which is what we like. It is durable, resists corrosion from caustic chemicals, corrosive fluids, oils, and gases, and withstands pressure and high temperatures. Among them, 304# and 306# stainless steel are used more frequently.
304# is a chromium-nickel material that resists corrosion caused by water, heat, salt water, acids, minerals, and peat soil. Widely used in the delivery of air, water, natural gas, steam, and chemicals to storage tanks as well as residential piping, kitchen, and food applications.
316# has a higher nickel content than 304# and has added molybdenum for better resistance Corrosive to corrosive chemicals, corrosive liquids, oils, and gases, and able to withstand pressure and high temperatures. Commonly used in chemical manufacturing, industrial and chemical transportation, food production, and processing to transport air, water, natural gas, steam, and chemicals
