A pipe fitting having a base configured to engage with a pipe, the base having a mounting seat configured to engage directly with the pipe, a base ring configured to engage with the mounting seat, and a base flange configured to engage with the base ring, a top hat configured to engage with the base, the top hat having a top cap, a top hat ring configured to engage with the top cap, and a top hat flange configured to engage with the top hat ring, wherein the top hat flange is further configured to engage with the base flange to form a fitting cavity. A pipe flow controller may be in fluid communication with the internal pipe volume through a threaded nipple, while also being securely housed within the fitting cavity, thus protecting the pipe flow controller from corrosion, impacts and other forms of damage to prevent leakage.

A method of facilitating sanitizing interior spaces of an aircraft using a pre-conditioned air (PCA) system. The method comprises cutting an opening in a duct wall of a pre-conditioned air (PCA) supply duct of the PCA system. Further, the method comprises installing a device in the PCA supply duct around the opening, coupling an inlet opening of the device with a device outlet port of a sanitizing device after the installing, wherein a sanitizing agent generator of the sanitizing device generates a sanitizing agent for transferring the sanitizing agent to the inlet opening through the device outlet port. Further, the method comprises injecting the sanitizing agent into the PCA supply duct from an outlet opening of the device based on the transferring. Further, the sanitizing agent mixes with the PCA based on the injecting. Further, the sanitizing agent is supplied to the interior space along with the PCA.

A multi-sensor mounting system and method includes a secondary pipe and an adapter. The secondary pipe comprises a fastening device configured to fix the secondary pipe to the process pipe, and a valve that is switchable between an open state and a closed state. The adapter detachably connects a sensor module to the secondary pipe. The valve allows a sensing probe of the sensor module being inserted into the process pipe in the open state, and to block a fluid flow in the secondary pipe in the closed state, for example, for times when the sensing probe is removed from the secondary pipe.

A tapper for tapping a water main is disclosed. The tapper includes a tapping portion having an open first end for coupling to a saddle fitted on a water main. The tapping portion defines a first interior space to be fluidly connected to the water main. A coupling portion extends from the tapping portion and has a receiving end for receiving a service line. The coupling portion has a second interior space fluidly connecting the first interior space and the receiving end. A cutter is arranged in the first interior space. The cutter is advanceable from a starting position to a tapping position at the first end and retractable to the starting position. Related methods are also disclosed.
