A fluidic piping system for aircraft, comprising a pipe made in a single piece and an insulating sheath surrounding the pipe. The pipe comprises potential cutoff zones defining sections of the fluidic piping system, reinforced zones arranged in pairs on either side of each potential cutoff zone, and non-reinforced zones defined between the pairs of reinforced zones as intermediate zones. An aircraft system, such as a ventilation and air conditioning module for an aircraft avionics bay, can comprise a limited number of such fluidic piping systems, and can easily be repaired by replacing a damaged section of the piping without it being necessary to disassemble the aircraft equipped with such a system.

A system and method for pipe insertion in live gas mains includes isolating a section of the gas main and taking measurements of service line connection points. This data is then used to prepare a pipe to be inserted into the gas main by drilling holes and applying fittings at the appropriate locations. The prepared pipe is then inserted into the gas main and the service lines are connected to it without the need to excavate the street over each service connection. The inserted pipe is then fluidly connected to the cut ends of the gas main and gas flow is routed through the newly inserted pipe and the attached service lines, while gas continues to flow through the original portions of the gas main that still remain in service.

An apparatus and a method of extracting buried lead water supply pipe with minimal excavation and which allows removal and containment of the lead pipe. The extraction apparatus includes a frame having an adjustable height mast and a plurality of guide pulleys with at least a first guide pulley mounted on the frame and at least a second guide pulley mounted on the mast. A first cable with a length closely matching the length of the pipe being removed is directed through the buried pipe and connected thereto by a leading collet and a lagging collet which are secured to opposite free ends of the lead pipe. A pulling cable preferably extends from leading collet and is directed around the first and second guide pulleys before being connected to a winch or the like. The mast height is adjusted so that the distance between the first and second guide pulleys is at least that of the length of the pipe being removed.

A pipe coupling and a method of use are disclosed. The pipe coupling including an elongated housing including a first end and a second end, a stop located on an inner diameter of the housing, the stop located between the first end and the second ends of the housing, wherein a distance from the stop to one of the first and second ends is at least two times a distance from the stop to the other of the first and second end of the housing, and at least one marking on an outer surface of the housing adjacent to the first end of the elongated housing, the at least one marking extending towards the second end for a predetermined length.

A pipe adapter including an inner tube member, a fastener member, an outer sleeve member, a compressible sleeve member, and a fitting member. The fastener member may have threads on an inner diameter adapted to matingly engage a threaded portion of the inner tube member along a proximal section thereof. The outer sleeve member may girdle the inner tube member and connect to and extend outwardly from the fastener member. The compressible sleeve member may be configured as at least one ring positioned to overlie the outer tube member. The fitting member may connect to a distal section of the inner tube member. At least a portion of at least one of the fitting member and the compressible sleeve member may be positionable within a portion of a pipe. The compressible sleeve member may extend outwardly from a longitudinal axis of the inner tube member toward the pipe.

Disclosed are methods and apparatuses for removing and/or installing valves located between two fixed pipe spool pieces. The valves can be located between first and second immovable pipe spool pieces having a fixed distance between the first and second immovable pipe spool pieces, and in the process of removal a gap is created between the first and second immovable pipe spool pieces. The immovable pipe spool pieces can have longitudinal axes which are parallel, and the gap created along a longitudinal line which is parallel to the two longitudinal axes of the pipe spool pieces. The longitudinal axes of the first and second pipe spool pieces can be coincident with each other.

A pipe coupling structure includes an electromagnetic valve and a passage block having an upper surface mounted with the electromagnetic valve and opposite side surfaces formed with an inlet port and an outlet port. The inlet port is connected to a PCV pipe through an inlet pipe joint, and the outlet port is connected to a PCV pipe through an outlet pipe joint. At least one of the inlet pipe joint and the outlet pipe joint is a union joint. The union joint includes a hollow cylindrical union end making contact with a first surface formed with the inlet port or a second surface formed with the outlet port and a hollow cylindrical union nut configured to connect the inlet port or the outlet port to the union end.
