●What Are Steel Pipe Nipple / Socket?
Steel pipe nipples, also called pipe sockets, are short sections of threaded pipe used to connect two fittings or pipes together. They have external threads on both ends that allow them to be screwed into internally threaded fittings or pipes. Steel pipe couplings are typically made from carbon or stainless steel and come in a variety of sizes and lengths to suit different piping systems. They are commonly used in plumbing, heating and industrial applications to join pipes, extend pipe lengths or create transitions between different pipe sizes.

●Sizes And Schedule Of Steel Pipe Nipple
size:Steel pipe nipples are available in a variety of sizes, both in length and diameter.
length:Steel pipe nipples are typically available in lengths from 1/2 inch to 12 inches.
diameter:Steel pipe nipples are available in diameters to match standard pipe sizes ranging from 1/8 inch to 24 inches.
The most common fitting sizes are 1/2 inch, 3/4 inch, and 1 inch.
Schedule:Steel pipe nipples also come in different specifications, which refers to the wall thickness of the pipe.
The most common steel pipe nipples sizes are Schedule 40 and Schedule 80.
Schedule 40 nipples are the most common and most economical option.
Schedule 80 nipples have thicker walls than Schedule 40 nipples, making them more durable and able to withstand higher pressures.
When selecting steel pipe fittings, it is important to consider the following factors:
