A piping system using Butt welding Fittings has many inherent advantages compared to forms.
•  Welding a fitting of the pipe to make it permanently leakproof.
•  The continuous metal structures forming between pipes and fittings adds strength to the system.
•  Smooth inner surface and gradual directional changes reduce pressure losses, turbulence and also minimises the actions of corrosion as well as erosion.
• A welded system occupies minimum of space.
