Abstract: A lateral pipe lining material comprises a tubular resin-absorbing material impregnated with a curable resin and a brim attached at one end thereof. The lining material is positioned so that the brim faces a peripheral edge of a lateral pipe opening of the main pipe. A ring-shaped gasket composed of an elastic material is attached to an upper surface of the brim, and a bonding resin is applied thereto. The gasket seals a gap between an inner peripheral surface of the main pipe and the brim. The lateral pipe lining material is evertedly inserted into the lateral pipe in a state in which the bonding resin applied to the brim is brought into contact with the inner peripheral surface of the main pipe. In such a configuration, ground water can be prevented from seeping into the bonding resin applied to the brim even if the ground water flows into the main pipe from a break of the lateral pipe.

An electric motor undergoes rotation in a first rotational direction to rotate the rotary body to wind the pipe lining material on the rotary body and undergoes rotation in a second rotational direction opposite to the first rotational direction. An eversion nozzle is attached to the storage container for everting the pipe lining material. When fluid pressure is supplied into the storage container to pull the pipe lining material out from the storage container and evert it via the eversion nozzle, the electric motor is caused to rotate in the second rotational direction due to the pulling out of the pipe lining material and to function as an electric generator to brake the pullout of the pipe lining material.

Abstract: There is provided a pipe lining method wherein a lateral pipe lining material and a main pipe lining material are securely joined. After a lateral pipe has been lined, a start liner is applied to the main pipe and a main pipe lining material is then inserted.

While the main pipe is being lined, the heating wire is heated to melt the start liner existing between the flange of the lateral pipe lining material and the main pipe lining material. When the resin in the main pipe lining material is cured, the main pipe lining material and flange of the lateral pipe lining material are integrated. This allows the lateral pipe lining material and main pipe lining material to be reliably joined.

A special plug may be used to direct the sealant into a selected portion of the conduit.

Abstract: A tubesheet is formed at the end of a module containing polymeric material for gas separation, by immersing the end of the module in an epoxy material, or its equivalent. A vacuum, or partial vacuum, applied at or near the opposite end of the module, tends to draw the epoxy material towards the source of the vacuum, and results in a tubesheet having a desired thickness, even though the epoxy material may have relatively high viscosity. The method produces effective tubesheets, while minimizing the degree to which the tubesheet covers the otherwise useful surface area of the polymeric material. The method thus produces gas-separation modules having enhanced productivity.
