pipe nipples

BSP threaded pipe nipple, also known as the British Standard Pipe, is a piece of hardware tool with a specific sort of screw threads. These standards of hardware tools could be seen being used worldwide because people have adopted them and use them in various applications like interconnecting and sealing the pipes and fittings in various industries and even for domestic purposes. In the pipe fitting industry, BSP threaded pipe nipples are also used to prevent leakage of liquid materials like water and oil that traditionally flows through pipes. There are some industrial showers in which very hot showerheads connected with a drain hose uses a person’s hair as an outlet for its waste material water (e.g., shampoo). In such cases, these threads help attach other fittings where one has the pressure head capability to hold water or oil.

Balanced pipe fittings

Balanced flange pipe fittings have the threads along their full length instead of BSP threaded pipes where they only extend from the nipple toward its outer surface of flanges, but once you look inside them a lot can be seen on how these are designed and manufactured nowadays in recent years. There is also another type of secondary fittings commonly known for massive valves that use proprietary materials among other things to exceed the strength and durability of BSP threaded pipes to carry higher pressures.

Numerous benefits

While a lot has been discussed about its numerous benefits, it is also something that takes up a decent space on your toolbox at times as well. In this case, using lightweight fittings with steel collars for attaching additional accessories like compression couplings would supply you with more time in reducing your current tools’ weight and saving some dollars wherever possible. These BSP screws are used so that one has to identify the male and the female parts correctly. The identification of male and female threads could be done very easily in a way that the male thread is designed in a way that it has an external shape, whereas the female thread has an internal shape. In order to seal and connect both the pieces, one has to twist them together. The tighter they are twisted the stronger and more durable the connection becomes.

Types of BSP Threads

Mainly there are two types of BSP threaded pipes that are easily distinguishable. Both these types are:

  1. Parallel (straight)
  2. Taper

We often get to hear parallel thread to be known as the straight thread as well. However, both the terms are considered to be correct for this type of BSP screw. Both the terms refer to the same type of screw that has a constant type of diameter. This thread type is also denoted in several ways, some of which are:

  1. British Standard Pipe Parallel thread (BSPP)
  2. British Standard Pipe Fitting Thread (BSPFT)
  3. British Standard Pipe Mechanical Thread (BSPM)

Some of these types of BSP threads often have a letter G typed over them. It is useful in order to separate it from the other threads.

The second type of the BSP thread that is known as the Taper type thread. This British Standard Pipe Taper thread differs in the way that it has a changing diameter that may increase or decrease along with the length of the thread. They often have the letter R marked over them in order to separate them from the other screw threads. People often confuse these Tapered threads with the NPT pipes due to close similarity but they are quite different in actuality as the NPT pipes have a flank of 60 degrees and the tapered BSP pipe would have an angle of 55 degrees.

Types of BSP Joints

Mainly there are two types of BSP joints that are considered. Both these types are:

  1. Jointing threads 
  2. Long screw Threads

Jointing Threads:

These are the types of pipe threads that need the mating of two parts to create a bond that seals properly. Both the parts involved in mating are known by their specific names based upon their thread. One of the parts is the taper male thread whereas the other part is known as either a parallel or a female taper thread. The first one is commonly known as a taper thread while the other two are also called a parallel or female threads. The creation of these threads involves melting them together with some added lubricant to form an extremely fine line of sharp teeth that need to be made flush and small enough so that they can bite into each other, thereby forming this seam we call threaded joints.

The length taken by these microscopic lines needs to be just right because too much or too little can cause these threads to break. This will happen only if there is not enough melt material and the two parts are simply about an inch or so apart, at which point breaking happens right in the middle of one thread seam.

The time it takes for a taper joint to form depends on how hard you press as well as your own personal strength/power when applying pressure with some sort of machine that creates heat . The melting process can take between 15 and 45 minutes.

Thread Rollers:

You need a lot of power to actually melt the tapers without over-pressing them by just one or two threads per minute, but you have to press for that time span at least 400 times within an hour in order for it all to be accomplished rather than using machine die cutting as some machines do where this is done beyond 80x100mm.

What gets you this much success with the taper thread dies is that when you have parts spinning at a high enough speed where they are exposed to extreme amounts of pressure, and then very rapidly heated for such time spans as mentioned above.

Long Screw Thread

The thread of this type of screw is according to British Standard Whitworth Thread. The joint is made by creating an angle of 55 degrees.
