A plastic valve for preventing distortion is disclosed. The plastic valve comprises a connection member made up of plastic, a case member formed on an outer surface of the connection member, and a flange member made up of plastic and formed at an end part of the connection member. A pipe is connected by being inserted into a hole of a central part of the connection member and a distortion prevention member for minimizing a force corresponding to distortion applied in a direction opposed to a direction of the connection is formed in the flange member. The connection member is made up of fluoride resin and the case member is made up of engineering plastic.

A pipeline clamp cover has a body and a flange. The body has a front face in sealing engagement with at least one peripheral side wall such that an enclosure having a rear opening is formed. The flange is provided in sealing engagement with a bottom edge of the at least one peripheral side wall and extends outwards away from the body.

A rodent deterrent system for a pipe system, the pipe system including a T-junction and a midsection riser. The deterrent system for the T-junction includes a first mesh screen configured to surround a vertical portion of the T-junction and a second mesh screen configured to surround a horizontal portion of the T-junction. Also, the deterrent system for a perforated riser includes a mesh wrap sleeve configured to surround the midsection of the riser. Alternatively, the riser midsection sleeve can be lengthened so that the second mesh is not needed as the lengthened sleeve also performs the same function as the second screen.

A heated drain or vent pipe system provides a low-cost and efficient temperature regulator for drain or vent pipes that are exposed to freezing temperatures to prevent the pipes from freezing. The heated pipe system includes an embedded resistance wire connected to a transformer that supplies a low voltage of electricity to the resistance wire. The resistance wire heats up due to electricity passing through the wire and transfers that heat to the pipe. The resistance wire is embedded in the wall of the pipe and maintains the pipe at a temperature above freezing. The heated pipe system may include a safety limit switch to disable the flow of electricity to the resistance wires if the pipe is overheating. The heated pipe system can be installed with air conditioning system drains, roof drains, and two-way vents that are exposed to freezing temperatures.

A fuel tube protector for a vehicle includes a protective member configured to surround a circumferential surface of a fuel tube disposed between a fuel tank and an internal combustion engine, and a fixing member provided at both distal ends of the protective member to fix the protective member to the fuel tube, wherein each fixing member includes a body surrounding and holding the circumferential surface of the fuel tube, and first fixing legs protruding from a side surface of the body and fastened to the respective distal end of the protective member.

A robotic vehicle for moving above ground while fabricating a subsurface polymer layer to protect an underground structure is provided. The robotic vehicle includes: a body; a rotational member that contacts the ground and moves the body over the ground; a ripper assembly having a proximal end that moves with the body, and a distal end that moves underground at a fabrication depth in response to the movement of the proximal end while fabricating the polymer layer; a ground penetrating radar (GPR) that locates and measures a depth of the underground structure below the ground; and a computerized control system that controls the rotational member, the distal end of the ripper assembly, and the GPR to move the body over the located underground structure while tracking the location of the underground structure and fabricating the polymer layer at the fabrication depth and above the measured depth of the underground structure.

A removable cover to protect a connector between two conduits includes a single body having a wall surrounding an interior volume. The body has a neck sized to grip a portion of a first of the conduits. The body has a size-adjustable section to permit the body to be shortened or lengthened. The body has a casing section. The casing section protects a coupling connecting together the two conduits.
