Common Connections And Standard Sizes Of Threaded Nipple Pipe Fittings

Nov 8, 2023 | NEWS

A pipe fitting is one of the most important components of a fluid handling system, installed at a critical connection point, it must provide a seal to improve operational safety and efficiency. There are many different fittings available for tube fittings, each type suited to different needs. How do we make the right choice?

Here’s a look at the common options available to buyers and their respective advantages provided by YINUO,China’s leading pipe fitting factory.

Pipe fittings are used for straight line connections such as instruments, and the connection forms are socket welded or threaded. It is mainly used for small diameter low pressure pipelines, for the parts that need to be installed and disassembled frequently, or as the final adjustment of the pipe with threaded fittings.

There are a wide variety of nipple pipe fittings, and commonly used nipple pipe fittings can generally be divided into hard nipple pipe fittings and nipple pipe fittings. If it is divided according to the connection method of the nipple pipe fitting and the pipe, the hard pipe joint has three kinds of flaring type, sleeve type and welded type, and the hose nipple pipe fitting is mainly the buckle type hose nipple pipe fitting

Main types of nipple pipe fitting

Threaded nipple pipe fittings

Threaded nipple pipe fittings are one of the most common options for securing the connection of two threaded pieces, one external, with threads protruding from the outside of the fitting; The other is an internal thread with a thread inside the fitting. A connection is formed when the external thread is screwed into the internal thread and secured by tightening the connection.

The threaded nipple pipe fitting contains a special kind: the pipe nipple threaded one end, which is also called the thread welded nipple pipe fitting. It connects two types of nipple pipe fitting with one end being a external thread and the other end being a welded steel pipe by welding. This pipe nipple threaded one end is usually used in cases where one pipe is directly connected to another pipe, which can improve the strength and tightness of the pipe.

Compression nipple pipe fittings

Compression fittings are another common option, using ferrule to create a leak-proof seal. When the nut of the joint is tightened, the ferrules are compressed between the nut and the receiving joint. Due to this compression, the ferrule effectively bites into the tube, resulting in a firm grip and tight seal. Compression fittings for compression fittings are also easy to assemble and remove.

Common size of nipple pipe fitting

The size unit of the pipe joint is expressed by ips, IPS is the standard size of the pipe thread, which is a kind of inch size. In this standard, IPS stands for Iron Pipe Size, and 1/8 ips stands for pipe diameter size of 1/8 inch.

The 1/4 ips threaded nipple pipe usually refers to the 1/4 inch threaded nipple pipe, which is often used in:

  •  audio equipment, such as guitar, electronic organ, stereo, etc., to connect the input and output of audio signals.
  • The 1/4 ips threaded nipple pipe can also be used in video equipment, such as cameras, monitors, etc., to connect the input and output of video signals.
  • 1/4 ips threaded nipple pipe can also be used in communication equipment, such as radios, walkie-talkies, etc., for connecting the signal transmission between the antenna and the device.
  • 1/4 ips threaded nipple pipe can also be used in electronic equipment, such as televisions, computers, etc., for connecting the input and output of audio and video signals.
