A system and method to inspect and monitor stress, strain, leakage, corrosion and disjointing of rigid metallic and non-metallic connector fittings used to join sections of non-metallic flexible reinforced thermoplastic pipe (RTP), as well as inspecting and monitoring the structural health of RTP in the area of connections with casement shields concentrically mounted on and adhered to the outer surface of the RTP at or adjacent to connection with a rigid connector fitting, monitoring sensors installed in the casement shields, a management system for receiving, processing and transmitting information gathered from the sensors via SCADA or other computerized means for monitoring and regulating strain impact, determining stress level and direction, potential leaks and temperature spikes at connector fitting areas, and a mechanism for acoustical detection or simulation, with a computer system for receiving, processing and transmitting information gathered from acoustical micro packs on the casement shields.

The present invention relates to a sealing system for a pump configured to pressurize a volatile liquid, such as liquid ammonia. The sealing system (2) includes a stuffing box (35) forming a barrier chamber (30) and a pump-side seal chamber (43), a mechanical seal (20) arranged in the barrier chamber (30), and a barrier-gas supply system (32) for supplying a barrier gas into the barrier chamber (30). The barrier gas has a pressure higher than a pressure of the volatile liquid in the pump-side seal chamber (43). The pump-side seal chamber (43) is located between an impeller (7) of the pump (1) and the mechanical seal (20). The barrier-gas supply system (32) includes a pressure control valve (50) configured to maintain a constant difference between pressure in the barrier chamber (30) and pressure in the pump-side seal chamber (43).

The present disclosure relates to a sensor system for monitoring the sealing of the connection between a sensor holder and a sensor that is mounted on the sensor holder. The sensor system includes a sensor holder, a sensor that is mounted on the sensor holder, and a leakage detector with a channel, which is arranged in the sensor holder and consists of one or more straight sections that are mounted perpendicular or parallel to the longitudinal axis of the sensor.

A mechanical seal testing system includes a mounting ring and a testing table. The mounting ring includes a first side configured to couple to a mechanical seal, the mechanical seal configured to couple to an oil pump, and a second side configured to couple to a stuffing box, the stuffing box configured to couple to a water pump. The testing table includes a surface configured to collect fluid leaked by the mechanical seal or the stuffing box. The mounting ring is coupled to the surface of the testing table.
