Standard single-fitting replacement
Small-diameter pipes (DN100 and below): Skilled workers can complete a single replacement in just 5–10 minutes; the process involves simply loosening the old coupling, swapping in the new fitting, and tightening the bolts.
Large-diameter pipes (DN350 and above): Using split-housing grooved couplings for large-diameter pipes is more than three times faster than flange connections. A single replacement takes approximately 15–30 minutes, reducing downtime by 50% compared to traditional welding methods.
Replacement in complex scenarios
Confined spaces: Grooved fittings occupy only 70% of the space required by flanges and do not necessitate extensive dismantling of surrounding structures; a single replacement can be completed within 30 minutes.
Batch replacement of multiple fittings: With pre-fabricated components and prepared pipe ends, a team can replace 3–5 fittings per hour, boosting overall efficiency by more than 40% compared to traditional connection methods.
