Pipe fittings are used in a wide range of industries and applications, including plumbing systems in residential and commercial buildings, water distribution networks, oil and gas pipelines, chemical processing plants, power generation facilities, and HVAC systems.

Pipe fittings come in a wide range of sizes, from small diameters used in residential plumbing to large diameters used in industrial piping systems.

They are manufactured according to various standards such as ASME B16.9, ASME B16.11, MSS-SP, ASTM, DIN, and JIS, which specify dimensions, materials, pressure ratings, and testing procedures to ensure quality and compatibility.
