Dalian Detai Ganghua Gas Co., Ltd. utilizes our company's portable telemetry laser methane detector and vehicle-mounted laser inspection system for pipeline patrol, gas facility inspection for end-users, and leak point positioning during emergency response to gas leaks. During operation, the inspection personnel detected multiple gas leaks at the joints between newly installed natural gas coils and elbows. Leveraging the precise leak location data provided by the portable telemetry laser methane detector, the team promptly performed targeted repairs. The gas company indicated that, due to the lack of efficient and reliable detection equipment previously, such scenarios had long been a blind spot in monitoring. Furthermore, the equipment has significantly improved patrol efficiency, reduced labor intensity of inspection work, and greatly enhanced the capability to identify potential leak hazards, thereby facilitating the early elimination of accident risks.
