Abstract: A process for porting air inflated flexible resin impregnated cured in place liner by pulling without loss of pressure is provided. A selectively openable bulkhead fitting is installed at the pull-in end. The filling may be installed in the end of a pull- in liner; on a porting sleeve or secured to an inflated pulled in or inverted liner. A port is formed through the bulkhead fitting by cutting a hole through the valve assembly. A steam fitting with an exhaust hose is coupled to the bulkhead fitting while maintaining pressure in the inflation bladder. Steam for curing the resin is then introduced into the inversion apparatus to cure the resin and is exhausted through the exhaust hose.

Abstract: An air inversion and steam cure apparatus (11) for installing a flexible resin impregnated cured in place liner in an existing conduit is provided. The apparatus has a low friction seal between a moving liner (27) and the stationary apparatus gland (28). The gland is operated and adjusted by displaceable members (36) that move substantially perpendicular to the liner being inverted to engage the moving liner as it passes through the gland. No part of the gland extends into the chamber so that once a pre- shaped gland is adjusted, the pressure on the moving liner is not increased. As the liner reaches the distal end, it enters a sample and porting pipe with an exhaust pipe gland and exhaust pipe and is pierced by a rigid porting tool. Steam is then introduced into the liner to cure the resin and is exhausted through an exhaust hose connected to the porting tool. After cure, steam is replaced with air to cool the liner and the ends are cut to restore service through the existing conduit.

Abstract: A resin impregnated lining tube (2) for the lining of pipelines or passageway is provided with a prelining tube (38) prior to insertion into the pipeline by the insertion of a stack (10) of prelining tube material into one end of the lining tube (2), a corresponding end of the prelining tube (38) being everted to lie outside the lining tube (2) end and a quantity of liquid is provided within the everted portion of prelining tube (38). Further eversion of the prelining tube (38) onto the inside surface of the lining tube (2) is caused by upward movement of the lining tube (2) and previously everted prelining tube (38) between a pair of upper (28) and lower rollers (14), during which time the stack (10) of prelining tube (38) freely unravels. A float (42) may be provided above the stack (10) of prelining tube (38) to maintain its position within the eversion liquid (18), and further the apparatus may be held within a nitrogen spray tank (32) to cool the lining during production.

Abstract: A resin impregnated cured in place liner with an integral inner impermeable layer, (22) a method for its manufacture and an apparatus to do this are provided. The liner is formed from a resin impregnable material having an impermeable layer bonded to one surface. The material is formed into tubular shape with the impermeable layer on the outside of the tube about a tubular forming member and continuously everted into the tubular forming device to place the impermeable layer on the inside. An outer impermeable film (31) is placed about the inner tubular layer (28) and may be impregnated with vacuum in the usual manner. Alternatively, the tubular resin impregnable material may be passed through a resin tank (53) and impregnated with a curable resin prior to being wrapped with an outer impermeable layer. The impregnated liner is then suitable for pull-in-and-inflate which can be by steam in view of the integral inner impermeable layer of the liner.

Abstract: The invention provides that a reinforced resin impregnable flexible tubular structure (68) is manufactured by feeding an inner layer (12) in tubular form over a floating mandrel (62) which is held magnetically suspended so that the layer (12) can be fed onto one end and off the other end of the mandrel (62). As the inner layer (12) is being so fed, reinforcing filaments (44-50) onto which adhesive has been sprayed, are helically wound round the inner layer (12). An outer resin absorbent layer (58) is then applied and that layer has an outer impermeable coating (59) so that the inner and outer layers (12, 58) of the resulting structures (68) can be impregnated with resin in which the reinforcement (44-50) is immersed by charging the resin into the inside of the structure (68).

Abstract: A process for lining an existing pipeline or conduit with a flexible resin impregnated cured in place liner by pulling in the liner and inflating a resin impregnated inflation bladder with air and curing the liner with flow-through steam without loss of pressure is provided. The liner includes a resin absorbent material in tubular form with an impermeable membrane forming an outer layer. The inflation bladder also includes a resin absorbent material in tubular form with an impermeable membrane forming an outer layer and an exhaust assembly at the trailing end and is passed through a pressurized inversion apparatus into the collapsed liner. As the bladder reaches the distal end, the exhaust assembly exits the everting bladder and is coupled to an exhaust hose. Steam is then introduced the inversion apparatus to cure the resin and is exhausted through the exhaust tube. After cure, steam is replaced with air to cool the liner and the ends are cut to restore service through the host pipe.

Abstract: The invention provides that a pumping unit can arrange to evert tubular members (26) into and along underground passageways (12). The pump unit is located at ground level and comprises a first section defining a sphincter valve (33), and a second section defining a pressure chamber (16). The sphincter valve is used to control the infeed of the tube and also to provide a seal of a pressure chamber. The pressure chamber is partially filled with water and is pressurised above the water with air from a supply (92) which also supplies the sphincter valve section. The two sections can readily be uncoupled by collapsing of the sphincter valve and the sphincter valve serves to seal the lower section in use. The upper side of the sphincter valve section is open to atmosphere and forms the infeed aperture for the tube.
