For installation, connect the double flange limit expansion joint to both side flanges. Adjust the product length to match pipe/flange connections, tighten gland bolts evenly in diagonal sequence, then set limit nuts to allow controlled pipeline expansion/contraction while maintaining safety. Consider pipeline pressure, temperature, and media characteristics to ensure proper joint performance.
