A piping system using butt-weld fittings has many inherent advantages over other forms. Welding a fitting to the pipe means it is permanently leakproof. The continuous metal structure formed between pipe and fitting adds strength to the system. Smooth inner surface and gradual directional changes reduce pressure losses and turbulence, and minimize the action of corrosion and erosion. A welded system utilizes a minimum amount of space.
