A Piping system using Butt-weld Fittings has many inherent advantages over other forms. Welding a fitting to the Pipe means it is permanently leak-proof.
The continuous metal structure formed between pipe and pipefittings adds strength to the system.A welded seems utilizes a minimum of space.
Applicable Standards of Butt-weld fittings are ASME / ASTM and MSS Standards.The main Butt-weld fittings used are Elbows , Caps, Tees, Concentric Reducers, Eccentric Reducers etc. Generally Pipe fittings are measured by their diameter and , wall thickness. This is known as Schedule. Fittings can also be defined by their material grade and whether they are seamless or welded. Diameter refers to outside diameter of a pipe or fitting.
