AI Technical Summary
Thick-walled corrugated pipes are prone to misalignment during connection, leading to eccentric leakage. The connection is also difficult to detect, affecting normal operation.
The sealing mechanism includes two semi-rings, a semi-ring sealing strip, a hot melt adhesive layer, and stainless steel cable ties or heat shrink tape. The stability and sealing of the corrugated pipe connection are ensured by the closing of the semi-rings and the sealing connection of the hot melt adhesive layer, combined with the fastening of the stainless steel cable ties or heat shrink tape.
This effectively avoids corrugated pipe misalignment, improves installation efficiency and sealing, and ensures the stability and quality of corrugated pipe connections.
