What Is A Hex Nipple?

ASME B16.11 Hex Nipple differ from standard to standard. The threaded hex nipple is a type of nipple fitting that has a hexagonal gap between the threaded ends. There are different kinds such as the threaded reducing hex nipple or the Stainless Steel Threaded Hex Nipple. The threaded hex nipple pipe is connected with the nipple with threads but in contrast to the ordinary nipples, these can be tightened with a hex tool. ANSI B16.11 Forged Threaded Hex Nipple is a standard that has nipple diameters up to 4 inches.


The Difference Between Hex Nipple And Pipe Coupling?

  • Threaded Hex Nipple Dimensions can be gained in different standards. The Hex Nipple standard includes nipples up to 48 inches in diameter.

  • The threaded pipe coupling is a short length of pipe used to connect two pieces of pipe without the need for much space. A two inch pipe coupling can have either male threads at one end or female threads and no thread on the other end.


How Many Pipe Nipple Types?

  • Close Nipple

  • Hexagonal Nipple

  • Long Hex Nipple

  • Reducing Nipple

  • Hose Nipple

  • Welding Nipple

  • Barrel Nipple

  • Close Nipple


Stainless Steel Reducing Hex Nipple Use In Chemical Industries?

The materials differ such as the ASTM A182 Threaded Hex Nipples and the ASME A105N Threaded Hex Nipple. The Hex Nipple is made up of alloy steel and is forged to get the Forged Hex Nipple. The uses of Forged Hex Nipple are various. Threaded Fittings Hex Nipple can be used to connect two fittings where tightening is difficult because the tightening of the Stainless Steel Threaded Hex Nipple becomes easier with the hexagonal gap for tool grip.


How Many Types Are There To Connect The Ends Of Pipe Nipples?

ASME B16.11 Hex Nipple can be used in oil and gas industries, chemical industries, ketch up industry, waste water management systems, pollution control systems and others. Forged Threaded Hex Nipple is the most used with sizes less than 4 inches. Forged Screwed Hex Nipple can be used as an alternative to other nipples when the working space is limited and the moving of pipes are difficult. Screwed Hex Nipple 3000LB Threaded is a pressure class indicating the maximum pressure that could be applied on this class of nipples.
