European pipeline maintenance contractor Challenges: It is difficult to inspect corrosion, welding defects and scaling inside bent pipelines. Humid field environments demand high waterproof performance. Portable equipment is required for field service. Songyin Solution: IP67 waterproof 720° articulating borescope with long flexible cable. Real-time image transmission supports remote assessment by back-end engineers. Outcomes: Non-destructive pipeline inspection reduces excavation and pipe dismantling cost. Compact for on-site field inspection; captured footage can be attached to official inspection reports.
