A method of lining a pipe with a lining mixture formed from a dry component and a liquid is discussed. The method includes placing the dry component in a dry component surface container located above ground, conveying the dry component from the dry component surface container to a dry component subterranean supply container located underground, conveying the dry component from the dry component subterranean supply container to a mixer located underground, mixing the dry component with the liquid to form the lining mixture, and applying the lining mixture to the pipe with a mixture applicator.

A method for depositing an electrically conductive metal onto at least one portion of the inner surface (3) of an internal cavity (2) of a waveguide (1) includes: preparing a suspension containing at least one liquid and at least one precursor of the electrically conductive metal in suspension in said at least one liquid; coating at least one portion of the inner surface (3) of the internal cavity (2) of the waveguide (1) with the suspension, and heat-treating at least said portion of the inner surface (3) of the internal cavity (2) of the waveguide (1) coated with the suspension. A method for manufacturing a metallized waveguide can implement this deposition method.

Spray devices that have been preconditioned with an iodine-containing conditioning agent prior to being deployed with aqueous iodine. In some embodiments, each spray device contains one or more materials that will be wetted by the aqueous iodine during use and that have been preconditioned to contain iodine so as to inhibit iodine absorption from the aqueous iodine added to the spray device after the preconditioning. Methods for preconditioning spray devices are also disclosed. In one example, surfaces of spray-device components that will be wetted by aqueous iodine during deployment are exposed to an iodine-containing conditioning agent and, while exposed to the iodine-containing conditioning agent, are thermodynamically treated. Methods of using spray devices for dispensing aqueous iodine for any one or more of a variety of purposes are also disclosed.

Disclosed is the treatment of the interior walls of a fluidic channel with a self-assembled monolayer of an organophosphorus acid.

A pipe-repair tool is disclosed. The pipe-repair tool includes a first chamber to hold a first pressurized sealant and a valve to selectively allow the sealant to flow from the chamber into the interior of a pipe to be repaired. The tool may include a second chamber to hold a second pressurized sealant when using a two-part sealant, in which case the first sealant and the second sealant flow through a mixing chamber when flowing from the first and second chambers to the interior of the pipe. The valve may be a mechanical valve that is opened by moving the tool relative to the pipe to be repaired. The valve may be an electrically controlled valve that is opened with an electrical signal.

A method and apparatus is disclosed for additive manufacturing and three-dimensional printing, and specifically for extruding tubular objects. A print head extrudes a curable material into a tubular object, while simultaneously curing the tubular object and utilizing the interior of the cured portion of the tubular object for stabilizing and propelling the print head.

A method of automated pipeline chemical batch treatment includes receiving treatment information at a control system of a pipeline. If the treatment information includes an instruction to activate a pump system, the method includes transmitting an activation signal from the control system to the pump system in accordance with the treatment information. The activation signal causes the pump system to pump one or more chemicals from a chemical feed system into the pipeline. If the treatment information includes an instruction to deactivate the pump system, the method includes transmitting a deactivation signal from the control system to the pump system in accordance with the treatment information, wherein the deactivation signal causes the pump system to stop pumping one or more chemicals from the chemical feed system into the pipeline.

Embodiments, described herein relate generally to devices, systems, and methods for producing lubricious surfaces with enhanced durability and which increase the ease of communication of viscous liquids across the same. The system can include a liquid-encapsulated surface including a substrate, a member coupled to the substrate, and an encapsulating liquid disposed on a surface of the member. In some embodiments, the surface of the member can have a chemistry such that the encapsulating liquid preferentially wets the surface and maintains lubricity in the presence of a contacting phase. In some embodiments, the encapsulating liquid can be substantially immiscible with the contacting phase, and/or can have a thickness of less than about 200 microns and/or can have a receding contact angle of less than 20 degrees in the presence of the contacting phase, in some embodiments, a liquid delivery mechanism can be configured to transfer the encapsulating liquid to the member.
