Fabricated Steel Mechanical Slip-Type Expansion Joints

The AWWA C221 standard outlines detailed specifications for fabricated steel mechanical slip-type expansion joints, which are essential components in water distribution systems for accommodating thermal expansion, contraction, and other movements. These expansion joints facilitate the flexibility and integrity of piping systems, particularly in areas prone to temperature variations or ground settlement. AWWA C221 provides guidelines for the design, fabrication, testing, and installation of slip-type expansion joints, covering aspects such as materials, dimensions, pressure ratings, movement capabilities, corrosion protection, and quality control measures. Adherence to this standard ensures the proper selection and application of fabricated steel mechanical slip-type expansion joints, contributing to the reliability, durability, and efficiency of water distribution networks.
