Technical drawing depicting standardized pipe elbow fittings in two size variants (100mm and 125mm). The drawing displays multiple orthographic views including front, side, and sectional details illustrating the circular flanged connections and flow path. Each elbow features mounting bolt holes arranged in a circular pattern around the main body. The design incorporates standard fastening hardware with hexagonal bolt, overall, heads for secure installation within piping systems. The circular profile and connection interfaces conform to industry standards for compatibility with existing pipe infrastructure. Particular attention has been given to the transition radius of the elbow to minimize flow resistance while maintaining structural integrity at operational pressures.
