摘要： PURPOSE:To enable formation of a coated film having an optional thickness on the inside wall surface of a pipe by reducing the pressure in the pipe to suck the high-viscosity lining material into the pipe, inserting a pig made of an elastic material into the pipe and pressing and moving the lining material forward via the pig. CONSTITUTION:The pressure in the pipe 1 to be treated is reduced to suck the high-viscosity lining material 5 into the pipe so that the lining material 5 is accumulated at the inlet end of the pipe 1. The pig 6 made of the elastic material is inserted behind the lining material 5 to generate a pressure difference between the space behind the pig 6 and the space before the lining material 5, by which the lining material 5 and the pig 6 are integrally moved toward the outlet end side of the pipe 1. The need for cleaning the lining material supplying system at every end of the supply of the lining material is eliminated and the efficiency of the lining operation is extremely improved. The coated film of an arbitrary thickness between 0.5-4mm is formable on the inside wall surface of the pipe by changing the moving speed of the pig.

摘要： PURPOSE:To form a lining film of uniform thickness with a less amount of air without producing waste of paint by injecting mixed fluids of compressed air and paint in the form of a hollow inverted circular cone shape to the inside wall surface of a pipe. CONSTITUTION:Paint 5 is mixed with compressed air 8 to form mixed fluids A. The mixed fluids A are sprayed in the form of a hollow inverted circular cone shape to the inside wall surface in one end part of a pipe 9 to be lined, by a spraying device 16. The paint particles in the mixed fluids A are stuck on the inside wall surface of the pipe, and a liquidlike paint laminating layer B is successively formed. This layer B is forcibly flowed forward along the inside wall of the pipe successively by the mixed fluids A sprayed into the pipe. In this way, the lining film of uniform thickness is formed with a less amount of air without producing the waste of paint.

摘要： PURPOSE:To enable even the small-diameter pipes to be lined by mixing two-component mixed epoxy resin paints to mixed gas by means of compressed air and letting the same pass through the inside of the pipe at a high speed. CONSTITUTION:Epoxy resin paints of two liquids A, B are passed throuth constant-volume feeders 6, 7 and valves 13, 14 and are mixed to a fixed mixing ratio in a mixing device 2. Next, the mixture passes through a valve 15 and enters a mixing nozzle 3. Compressed air G on the one side goes through a valve 12 and is pressure-fed into the mixing nozzle 3, where it makes the epoxy resin mixed liquid to mist form to form the mixed fluid of the resin-air. This fluid enters an acceleration nozzle 4 through a mist pipe d. The other compressed air goes through a valve 11 then through a regulator 5 to become a high speed air flow which then enters the acceleration nozzle 4 through a valve 16. Here, the mist pipe d air and pipe c meet together and the mixed fluid is more accelerated and plunges into the pipe 1 to be coated by way of inlet pipe e and blow valve 20. The paint particles then deposit on the pipe wall to form a paint layer, after which they flow to an outlet 10 and are recovered into a recovery tank 8.

摘要： PURPOSE:To surely form a uniform lining film having a prescribed thickness by inserting a pig made of an elastic material into a pipe and pushing and moving a lining material forward by such pig. CONSTITUTION:The high-viscosity lining material (e.g., epoxy resin paint having 0.5-5mm threshold thickness of the sag of a coated film) is accumulated in the pipe 1 to be treated and the pig 6 made of the elastic material is disposed behind the same. A prescribed flow rate of working fluid 2 (e.g., compressed air) is supplied into the pipe 1 from the rear of the pig 6 to move the material 5 forward. More specifically, the coated film having an arbitrary thickness between 0.5-5mm can be formed on the inside wall surface of the pipe by regulating the flow rate of the working fluid to change the moving speed of the pig. The uniform lining film having the prescribed thickness is surely formed even with a large- or small-diameter pipe by controlling the flow rate of the working fluid in the pipe to the constant value.

摘要： PURPOSE:To eliminate the waste of paint and form a lining film of uniform thickness by injecting the mixed fluid prepd. by mixing synthetic resin paint and compressed air onto the inside wall surface of a pipe to be lined, and supplying air fluid from its behind. CONSTITUTION:Paint 5 formed by mixing a base consisting of an epoxy resin and a hardener is ejected in the form of mist into a pressure injector 6, where it is mixed with the compressed air from a compressor, whereby a mixed gas A is formed. This mixed gas A is blown through an injection nozzle 17 via an injection pipe 16 to the inside wall surface of the pipe in the form of a hollow inverted cone shape, and paint particles stick on the inside wall surface of the pipe. On the other hand, high pressure air 22 is blown into the high pressure air force-feed port 20 of an air ejector 15 for suction, whereby air flow B is formed. The paint in the mixed gas A stuck on the inside wall surface of the pipe is pushed forward by the mixed flow B and is coated on the inside wall surface of the pipe to 0.5-1mm. thicknesses.

摘要： PURPOSE:To efficiently line the inside wall of water pipes, etc. by filling paint between two pigs and letting the pigs progress in the pipe by air pressure, etc. CONSTITUTION:After the scale in a pipe 1 is removed, a launcher 2 is fixed in the inlet opening 10 of the pipe 1. Two pigs G are loaded in the launcher 2 and the space in the pipe is pulled to a vacuum by opening the valve 7 of a branch pipe. The valve 7 is closed and the valve 8 of a feed pipe is opened to fill the paint Q between the pigs G. The valve 8 is closed and injection valve 6 is opened to lead compressed air, etc. to the injection pipe 3 and the fluid of high pressure is injected into the launcher 2 from a nozzle 14. Then, the pigs G sandwiching the paint Q is pushed out from the launcher 2 and plunges in the pipe 1. Then, the paint Q deposits on the inside wall of the pipe little by little, thereby forming the film of a constant thickness. The fluid pressure pushing the pigs G is maintained constant by a pressure gauge 8 and valve 15.
