A multi-layered pipe of arbitrary length and cross-section is produced by co-extrusion of a lower polyolefin (C–C) outer body over the exterior surface of a tubular core of randomly, partially randomly, or blocky chlorinated lower polyolefin, the core having a wall thickness, measured in the radial direction, in the range from about 0. 025 mm to 5 mm. The tubular core is coextensive with essentially the entire length of the pipe. The tubular core comprises a major proportion by weight of the randomly chlorinated polyolefin (r-CPO), or, partially randomly chlorinated polyolefin (pr-CPO), or, a blocky chlorinated polyolefin (b-CPO), any of which may be blended with a minor proportion by weight of a blending ingredient. The r-CPO, pr-CPO or b-CPO, or a blend thereof, each has an extrusion temperature in the same range as that for the corresponding non-halogenated polyolefin, namely in the range from about 150 C. to 250 C.

Fire sprinkler system comprising a network of CPVC pipe lengths in which at least some of the pipe lengths are interconnected with mechanical devices having resilient sealing members that are chemically compatible with the CPVC composition. Repairs and system modifications can be made without the use of solvent cement. In-line joints are formed with a coupling device including a pair of arcuate coupling segments having a first end, a second end, and an interior concave surface extending between the first end and the second end. A longitudinal channel extends along the concave surface. At least one mechanical fastener is operative to detachably connect the pair of coupling segments. A resilient annular seal is located within the longitudinal channel of each segment. A branching device connects a branch pipe to a main pipe through an orifice in the main pipe utilizing a saddle-like sealing member. The pipe assemblies are able to pass UL testing protocols for wet fire sprinkler systems.

International Classification:
B32B 1/08 C08K 5/57
US Classification:
428 369, 524178
Abstract:
CPVC pipe in diameters in the range from 15 mm (0.5 inch) to 15.24 cm (6 ins), to carry hot and cold aqueous streams under 690 KPa (100 psi) pressure and 82.2 C. (180 F.) in continuous service, is extruded from a compound in which the CPVC has a high Cl content in the range from 66.5%-70%, when modified with either of two specific impact high rubber modifiers in an amount greater than 5 parts but no more than 6 parts per 100 parts of CPVC. Extruded CPVC pipe provides a HDB measured according to ASTM D2837-01 which is 25% or more greater than that required for commercial pipe as specified in ASTM D2846. As a result, both SDR-11 and SDR-13.5 pipe are produced which provide a HDB of at least 1250 psi (8.62 MPa) at the 100,000 hr intercept.
Pvc/Cpvc Composite Pipe With Metal Interlayer And Process For Making It

LUBRIZOL ADVANCED MATERIALS, INC. - Cleveland OH
International Classification:
B29C 65/00 F16L 11/00
US Classification:
156498, 138125
Abstract:
A composite pipe has a metal conduit sandwiched between inner and outer conduits of PVC/CPVC, each of which are adhesively secured to the interlaying metal conduit with a dried, solvent-free thin layer of a thermosetting bilayer adhesive which provides a bond with the metal, which bond fails in cohesive failure. Narrowly defined limits on the thickness of each conduit are found to provide a bendable composite pipe with an aluminum interlayer; and to provide a rigid non-bendable composite pipe with a steel interlayer. Making the composite pipe which meets required ASTM and NSF test considerations requires unexpectedly critical process steps. A process for making the pipe is disclosed, as are PVC/CPVC fittings which allow lengths of pipe to be solvent-cemented in them so as to seal the terminal ends of the pipe against infusion of fluid under pressure in the pipe, thus preventing delaminaton.

Abstract:
A process for producing bitumen employing a borehole that has been drilled into a subterranean hydrocarbon-bearing reservoir having a hydrocarbon. A void space is created at the bottom of the borehole. A bundle of spring-loaded guide tubes is inserted through the borehole and into the void space. Each guide tube is enclosed with a smaller diameter flexible tube that is connected to a source of an emulsifying composition comprising an aqueous phase and an emulsifying agent. The emulsifying agent comprises first and a second ethoxylated alkylphenol compounds wherein at least 1% by weight include more than 100 ethoxy groups. The emulsifying composition is released through the flexible tubes to form an oil-in-aqueous phase emulsion in the reservoir. The oil-in-aqueous emulsion is removed from the reservoir.
