LINING PIPELINES AND PASSAGEWAYS

Sewer & water pipe lining

A method of lining a pipe

In a method of lining a metal pipe with a rigid thermoplastics material lining tube, an adhesive is applied to the external surface of the tube or to the internal surface of the pipe, and the tube is inserted into the pipe. An internal pressure is applied within the tube and the assembly is subjected to an axially progressive heating so that air between the tube and the pipe is expelled and internal pressure presses the tube against the pipe. Axially progressive quenching follows the axially progressive heating. The tube may be of polypropylene and its surface etched e.g. by corona discharge.

A SYSTEM AND METHOD FOR REINFORCING COMPOSITE PIPES

A process for manufacturing pipes using thermoplastic pipe and "tape" (continuous fiber, fully wetted in a similar thermoplastic as the pipe) that embeds the fibers into pipe surface. In one embodiment, an ambient temperature (72 degrees F) tape is tightly wrapped around the cold pipe in a dry environment (relative humidity below 30). An external heat source is used to heat up the entire length of the pipe causing the thermoplastic to melt and the pipe to expand due to thermal expansion. Since the fibers have less stretch than the thermal expansion of the pipe the fibers will be embedded into the molten layer of the pipe.

IMPROVEMENTS RELATING TO THE LINING OF PIPELINES AND PASSAGEWAYS

... 2142183 9429098 PCTABS00034 In an established method of lining underground pipelines and passageways a lining tube which is impregnated with curable synthetic resin is filled with hot water to press the tube to the pipeline or passageway surface and also to heat cure the resin. When the cure has been completed the lining remains free standing in the pipeline or passageway surface. In this invention the same lining operation is performed but the heating is in stages by isolating lengths of the lining tube in turn and by circulating hot water through the isolated lengths in turn. Considerable advantage is obtained in that much less water needs to be heated.

Repairing e.g. PVC pipe

Pipes (including soft types) are relined internally by coating with a plastic repair tube which consists of an outer plastic film, a reinforcing core and (if desired) an innermost plastic film; the process follows testing for the size and inspecting the pipe. The size and renforcement of the liner are chosen to match the i.d. of the pipe; the reinforcing core is impregnated in thermosetting resin under vacuum whilstsqueezing the composite material in the resin and (if necessary) evacuating the space between the outer films; the repair tube is mechanically drawn into and pressed against the pipe by means of gas pressure; and curing the impregnating resin e.g. by irradiating with a robot, checking the temp. and pressure (plus composition if necessary) of the emerging gas.

The flexible tube is introduced into the pipe (1) and inflated, after which the resin (11) of the intermediate layer (8) is hardened by means of UV radiation produced inside the tube (101, 102; 112, 113; 122, 123, 125). For the manufacture of underground piping, the flexible tube (9) is extended in the open air at the desired position, inflated with air and hardened by natural UV-radiation at the point of storage.

Refurbishing underground pipes - by drawing through existing pipe two-ply plastic film with hard-setting resin core, inflating to size and hard setting resin

Laid pipework is refurbished (or produced) by drawing through the existing pipe a pipe which consists of inner and outer layers and at least one intermediate layer impregnated with a hard-setting resin which is then set hard, and the pipe is inflated, at least at the point where the resin is set. ADVANTAGE - The method is simpler, more favourable environmentally and more economical. It can be used even where the ground water has a high pressure. It produces perfectly sealed pipework capable of withstanding full pressures. It causes no contamination of any existing pipes, the soil, or the environment. It can be used just for the distances where it is required, e.g. can be made to measure and then laid immediately.

Reconstruction of damaged underground pipelines - three layer tube with transparent inner and outer layers and central curable layer is hauled into pipe, inflated and cured by light source

Process for removing buried pipelines involves drawing a three layer flexible tube through a faulty length of pipe. The tube comprises thin inner and outer layers and a central layer comprising reinforcement contg. a curable resin. When in position the tube is inflated to meet the pipe wall and the resin is cured to rigidify the tube. The resin can be self-curing, or cured with IR- or UV light, heat or gas. The resin system must have a long shelf life to allow for prodn., transportation, installation, and inflation. Pipes can also be produced at ground level by unrolling the laminated tube, inflating and curing by sunlight. USE/ADVANTAGE - Buried damage pipelines, pref. for water, sewage, etc can be renovated and resealed. New ground level pipes can also be produced. Process is simple, economic and environmentally friendly. It can be used in areas of high ground water pressure. A fault free pipeline is produced which prevents fluid escape.

The invention is characterised in that the tunnel kiln (10) further comprises a retractable thermal screen system (25) capable of being arranged in front of all or part of the radiating surface of some of the radiating elements (20), said thermal screen system involving the two side walls (14). Said thermal screen system enables to line with a heat-shrinkable sleeve objects with complex shapes, in particular with downward facing taper.

Advanced flexible hose and its manufacturing process

Pipeline lining method

A tubular pipe lining material impregnated with a thermosetting resin is inserted into a pipeline and made to expand and press against an inner peripheral surface thereof. Hot water or steam is sprayed onto the pipe lining material to cure the thermosetting resin impregnated therein. Hot water that has accumulated in a bottom part of the pipe lining material is pumped out to an external location by a pump and cooled by a cooling device to generate cool water, which is then sprayed via a hose onto the cured pipe lining material to thereby cool the heated pipe lining material. This enables the thermally cured pipeline lining material to be reliably cooled and rendering a water truck unnecessary that is required at a construction site to supply additional cooling water.

METHOD FOR MAKING A PROTECTIVE COATING ON A TUBE AND TUBE COMPRISING A COATING OBTAINED BY SUCH A METHOD

Le procédé consiste à déplacer le tube (1) en translation longitudinale et simultanément en rotation, à chauffer le tube (1), à déposer sur la surface externe du tube (1) une couche de poudre époxydique (9), à enrouler sur la couche époxydique (9) au moins une bande à l'état pâteux d'un matériau adhésif, à enrouler sur ladite bande de matériau adhésif (11) au moins une bande à l'état pâteux de polypropylène pour former une couche de polypropylène (16), à refroidir l'ensemble ainsi obtenu, à chauffer la peau de ladite couche de polypropylène (16) et à enrouler au moins une bande d'élastomère isolant thermique et incompressible à l'état pâteux pour former une couche d'élastomère (22). The method consists of moving the tube (1) longitudinally and simultaneously in rotation, heating the tube (1), depositing on the outer surface of the tube (1) a layer of epoxy powder (9), to be wound on the epoxy layer (9) at least one pasty strip of an adhesive material, to roll on said adhesive material web (11) at least one paste-like band of polypropylene to form a layer of polypropylene (16). ), cooling the assembly thus obtained, heating the skin of said polypropylene layer (16) and winding at least one band of thermal insulating elastomer and incompressible in the pasty state to form an elastomer layer (22). ).
