摘要:
In order to provide a resin line that can be produced inexpensively, that meets the static requirements under action of the vacuum, and that enables a more precise discharge of the matrix material independent of the bending radii at which the resin line is laid, the resin line is formed of a corrugated pipe (2) whose wall comprises through openings (4). The through openings vary in regard to shape, size and/or frequency across a length of a corrugated pipe section of the corrugated pipe.

An umbilical (2) has a center tube (4) that is a steel tube, and that the cross section of the center tube (4) at the extremity of the umbilical (2) is made corrugated on a length that extends substantially from the extremity to a distance from the extremity so that fatigue strain on non corrugated parts of the steel tube is avoided when the extremity of the umbilical (2) is inserted into a bend stiffener (1).

This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with a reinforcing stiffener. The corrugated pipe may include an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. In some embodiments, a stiffener may be positioned within the corrugation valleys. In other embodiments, a stiffener may be positioned within the corrugation crests.

A corrugated tube includes: a tubular body including outer-face bellows recess sections outer-face bellows protruding sections in a circumferential direction as viewed from an outside, wherein the outer-face bellows recess section and the outer-face bellows protruding section are alternately arranged continuously in an axial direction of the tubular body. Deep groove sections are formed in some of the outer-face bellows recess sections. The deep groove section has: a shape being recessed partially in a predetermined range in the circumferential direction; a shape protruding toward an inner side of the tubular body; and a shape having a pair of tapered sections as viewed from the axial direction of the tubular body.

A pipeline to transport a frozen medium is indicated which has an outer transversely to its longitudinal direction undulated limiting pipe, arranged inside are at least one metal pipe for guiding the frozen medium as well as a cooling pipe composed of metal for guiding a second frozen medium. In the limiting pipe hollow areas are available for evacuation. Fitted inside the limiting pipe are at least two transversely to their longitudinal direction undulated metal pipes for guiding the frozen medium, which are each surrounded by a thermal insulation. During the operation of the pipeline the frozen medium is led in different directions through both the metal pipes. Attached around both the metal pipes and the cooling pipe is a pipe shaped closed sleeve composed of a thermally good conductive material that is in contact with the cooling pipe.

An inspection system and method for scanning and recording defects in the surface of the smooth inner wall of dual wall corrugated plastic pipe during manufacture utilizing automated laser technology, in order to minimize potential disruptions in the manufacturing extrusion process and alleviate concerns as to improper formation of the inner wall. The inspection system includes conical laser pattern generator that passes through the dual wall corrugated pipe during the manufacturing process to complete 360 degree scan coverage of the surface of the inner smooth wall of the pipe. The inspection system further includes a set of cameras properly aligned to record comprehensive three dimensional coverage of the scanned image of the inner wall of the dual wall corrugated pipe. This inspection system and method has particular benefits in the manufacture of coilable dual wall corrugated plastic pipe, where the material make-up of the polymer melt used for the inner wall has been altered.

A multiple lumen hose includes a generally circumferential base wall. A plurality of corrugations extend radially outward from the base wall. A septum is disposed interior to the base wall such as to divide the interior of the base wall into at least a first lumen and a second lumen. A first scallop extends outward from the circumferential base wall between adjacent corrugations. A second scallop extends outward from the circumferential base wall between adjacent corrugations.

A method of installing an exhaust tube is implemented by inserting an exhaust tube into an exhaust pipe that leads from inside of a building to outside thereof. A support portion of an insertion jig is introduced into a through hole from a side of one end portion of the exhaust tube, and a projection of the support portion is engaged with a recess of the exhaust tube, so that the insertion jig is fixed to the exhaust tube. An end of the exhaust tube on the side of the one end portion having the insertion jig fixed thereto is inserted into the exhaust pipe, and the exhaust tube is pushed from inside of the building to outside thereof.
