A SIPP spraying apparatus for applying a liner material to the inner wall of a pipe, the apparatus having a transport unit, an articulating neck, a spinner assembly, proximity sensors and a plurality of positioning assemblies, wherein the positioning assemblies adjust the position of the spinner assembly as the apparatus moves through the pipe so as to maintain the spinner assembly centered within the pipe.

The present invention provides apparatus, including a pigging tool, that comprises a spraying mechanism configured to move along an inner surface of a pipeline, including a slurry transport pipeline in a minable oilsands facility or plant, and to spray a coating on the inner surface of the pipeline; and a curing source, including an ultraviolet (UV) light source, a microwave source or an RF source, configured to cure the coating sprayed on the inner surface of the pipeline in situ as the spray mechanism moves along the inner surface of the pipeline.

A well surfacing device, comprising: a surfacing head, including an inlet for deposition material disposed in a substantially vertical orientation and an outlet for deposition material disposed in a substantially horizontal orientation to a target surface; and a material feeding portion connected to the surfacing head, the material feeding portion delivering deposition material from above the head in a substantially vertical orientation downward to the surfacing head.

A contaminant capturing liner includes a cured product of a composition including an epoxy resin component including at least one alkanolamine modified epoxy resin and at least one hardener. The contaminant capturing liner includes at least one contaminant capturing material embedded therewithin, and the contaminant capturing liner is a permeable layer having a difference between dry glass transition temperature and wet glass transition temperature of at least 14 C.

The present invention pertains to a multilayer assembly, to a process for the manufacture of said multilayer assembly, to a pipe comprising said multilayer assembly and to uses of said pipe in various applications.

The present invention includes an inner anticorrosive and abrasive resistant coating (10) for steel pipes (1) used for the transport of fluids. The coating includes: a layer of epoxy resin (2) having free hydroxyl groups, which are applied directly to the inside 1a of the steel pipe (1); a layer of thermoplastic adhesive (3) applied directly onto the layer of epoxy resin; and a layer of 12-Aminododecanoic acid lactam with the formula (C.sub.12H.sub.23NO), which is applied directly onto the layer of adhesive.

A system for forming an elastomeric composition for application to a substrate includes an isocyanate component and an isocyanate-reactive component. The isocyanate component includes a polymeric polyisocyanate and optionally an isocyanate-terminated prepolymer. The isocyanate-reactive component is reactive with the isocyanate component and includes a polyol component and a polyetheramine. The polyol component is a mixture of (a) a hydrophobic polyol; (b) a polyether polyol different than the hydrophobic polyol and having a weight average molecular weight greater than 500 g/mol; and (c) a polyaminopolyol. The elastomeric composition is formed as the reaction product of the isocyanate component and the isocyanate-reactive component and may be applied as an elastomeric coating layer on a substrate such as a steel pipe. The steel pipe having the applied elastomeric coating layer satisfies the standard for use in the water supply industry as set forth in AWWA C222.

A system for field internally coating a pipe joint comprising a polymer application unit, which has a first cart configured to selectively advance inside a pipe; a first and a second tank configured to contain a first and a second polymer component respectively; a mixer to mix the first and the second component; a first and a second pump to feed the first and the second component respectively from the first and the second tank to the mixer, an applicator to apply the polymer to the pipe; and a conduit comprising a free end configured to be placed near the applicator to feed the polymer from the mixer to the applicator.

A metal pipe and a system of pipes, and a method of producing the same. The pipe is for conveying oil and gas. The pipe includes a metal coating in a transition region. The metal coating of the transition region obviates a subsequent coating of the inner surface of the transition region after connecting two pipes using a welding process in order to form a pipeline.

Material lining the inside surface of a section of pipe is removed by a hydrodemolition nozzle assembly mounted on a working end of an elongated boom. The opposed end of the boom is supported outside the pipe on a movable support for inserting and retracting the boom from the inside of the pipe. The nozzles remove the liner while the working end of the boom is supported by a wheel resting on the liner that has not yet been removed and that rolls along the inside liner as the pipe is made to revolve around the boom. The nozzles are oriented to eject the liner and water downstream and away from the boom.
