ASME B16.9 Lateral Tee are commonly used in piping systems where a new branch line needs to be added perpendicular to an existing pipeline. They are available in different materials such as carbon steel, stainless steel, alloy steel, and other metals, depending on the application. ASME B 16.9 Buttweld Lateral availbale in various forms and size, products like Elbows,Tee, Cross and educers etc.Buttweld fittings dimensions, dimensional tolerances are defined in the ASME B16.9 standards. Light-weight corrosion resistant fittings are made to MSS SP43. ASME B 16.9 Buttweld Lateral Pipe Fittings standard covers pressure-temperature ratings, materials, dimensions, tolerances,marking, testing, and methods of designating openings for fittings.
