Definition and Applications of Buttweld Fittings

Before getting down to the definition of buttweld fittings, let us initially define the term ‘pipe fitting’. The term pipe fitting is basically used to define a procedure that is commonly used in order to install, repair or even tube systems that are used for the conveyance of liquid, gas and at times even solid materials. All through the process, it is basically the selection, along with preparation of the pipes or tubing is carried out after which these are joined using the different means of repairing and location of pipe leakages.


So, what are buttweld fittings and what’s with their application?

Buttweld fittings are a rather popular fitting which is performed in a number of different settings by a fabrication company. In buttweld fittings, in order to prevent leakages on a permanent basis, a fitting is welded on to the pipe. The kinds of settings wherein these can be applied are inclusive of manufacturing, hydraulics, and super carriers etc.
The thing with buttweld fittings is that these can be used over different types of pipe and tubing materials that are inclusive of aluminum, copper, plastic, steel and believe it or not, but even iron!  The utilization of buttweld fitting typically tends to offer countless benefits when compared with over forms of fittings. The kinds of advantages that these offer include:

  • These offer significant strength to the system considering that they form a constant metal structure in between the fitting and the pipe
  • The pipe over which buttweld fittings are applied tend to become permanently leak-proof as the fitting is welded on to the pipe
  • These offer smooth directional changes together with a flexible inner surface, which basically reduces the amount of turbulence and pressure losses. It additionally reduces the effects of erosion and corrosion over the pipes
  • These take up minimum space as these are simply just welded on to the pipes

Apart from these, there are countless other benefits that buttweld fittings offer over other forms of fittings, which makes their utilization all the more alluring. What you should know about buttweld fittings is that these have beveled ends, wherein the shape of the bevel is dependent upon the original thickness of the wall. In terms of ferritic stainless steel, their thickness is around 5mmm, whereas for stainless steel, it remains at around 4mm. The ‘butt weld’ is basically created with the help of its beveled ends. These ends need to be welded into the piping components to create a ‘buttweld fitting’.

The materials that are most commonly used in order to produce buttweld fittings are stainless steel, carbon steel, cast iron aluminium fabrication, rubber, glass, copper etc.
