Pipe-liner eversion system and method
09724873 · 2017-08-08 ·

A pipe-liner system for use when lining a pipe interior features a pipe having a pipe opening end and a pipe interior wall. The system features a flexible, substantially-impermeable, elongate extender-tube and an evertable, flexible, elongate, tubular pipe-liner. The system features a substantially leak-proof pressure retaining closure-sleeve located on a pipe-liner second end. An extender-tube second end is attached to a pipe-liner first end via a substantially leak-proof connection there between. The combined extender-tube and the pipe-liner form a single continuous evertable tube, hereinafter referred to as an extended liner having the pressure retaining closure-sleeve enclosing an extended liner distal end. A length of the extender-tube and a length of the pipe-liner are each chosen so that the liner is caused to be accurately positioned within the pipe upon eversion.

The present invention relates to a production device of a cap-integrated tube container, and provides a tube container production device comprising: a first blocking part which is positioned outside a coil, that generates high frequencies, so as to block high frequencies generated from the coil; a second blocking part which is positioned above the first blocking part so as to block high frequencies generated from the coil; and a third blocking part which is positioned inside the coil so as to block high frequencies generated from the coil, and on the inside of which is formed a space for positioning a cap that is mounted on a tube container.

PIPE-LINER EVERSION SYSTEM AND METHOD
20170326784 · 2017-11-16 ·

A pipe-liner system for lining a pipe and methods of use thereof. A continuous, eversible extended liner is formed from a pipe-liner attached to an extender-tube via a substantially leak-proof connection there between. Lengths of the extender-tube and the pipe-liner are each chosen so that the pipe-liner is caused to be accurately positioned within the pipe upon everting the extended liner into the pipe by a pressurized fluid. The pipe-liner is held against an interior surface of the pipe being lined by inserting an inflatable bladder into the extended liner and filling the bladder with pressurized fluid. When a resin in the pipe-liner has hardened, the bladder is removed and the extender-tube is detached from the pipe-liner.

Friction welding element, and a method for connecting the friction welding element to a housing
09764417 · 2017-09-19 · ·

A friction welding method for fastening a connection bushing, such as a threaded bushing for example, in a housing. In order to improve the quality of the connection, the connection bushing is attached to the housing using a friction welding element. The friction welding element consists of the connection bushing, on which a friction welding shell with a radially outer friction welding contour is formed or molded. Connecting and sealing portions are produced between the friction welding element and the housing during the friction welding process by means of a special design of the friction welding contour.

Method for assembling thermoplastic tubes by induction welding

A method for assembling two tubes (1, 2) made from thermoplastic materials, that involves welding by heating two applied rotational contact surfaces of two parts of two tubes (1, 2), respectively, arranged end to end or overlapping coaxially (XX′). The method involves induction heating of at least one conductive welding element (4), arranged at the interface (3) between the two contact surfaces, by generating a magnetic field at said conductive welding element or elements, such that the melting of the thermoplastic materials constituting said contact surfaces produces a continuous and sealed weld at said interface on at least one closed loop along the entire perimeter of said interface.

Methods of joining or repairing lined pipes and associated apparatus
11739876 · 2023-08-29 · ·

A method of creating a weld between a liner of a section of lined pipe and an electrofusion fitting. The fitting comprises at least one heating element, which is suitably disposed on or in an outer surface of the electrofusion fitting and is electrically isolated from an inner surface of the fitting. The method comprises locating an end of the electrofusion fitting within an end of the section of lined pipe, locating an induction coil within a bore of the electrofusion fitting in the vicinity of the at least one heating element, and supplying electrical power to the induction coil to energise the at least one heating element by electromagnetic induction.
