Abstract
A thermally insulated pipe system includes a pipe with an outer diameter and a thermally insulating pipe section mounted on it. The pipe section has two longitudinal parts with longitudinal openings forming an aperture for the pipe. The parts face each other in a symmetry plane, with two webs in each opening that extend substantially to the symmetry plane and are arranged at an angle between 45° and 90°, forming a first groove between the webs and second grooves between each web and the surface of the opening.
Claims19
A thermally insulated pipe system comprising a pipe having an outer diameter and a thermally insulating pipe section mounted on said pipe, said pipe section comprising two longitudinal parts each having a longitudinal opening, providing an aperture for accommodating the pipe whereby the two longitudinal parts are facing to each other in a symmetry plane,
- wherein
- two webs are provided in each longitudinal opening of the parts, each web extending substantially up to the symmetry plane and being arranged under an angle (α) between 45° and 90° relative to the symmetry plane, thereby incorporating a first groove between the webs and second grooves between each of the webs and a surface of the longitudinal opening, wherein the first groove has a width (Wc) being larger than the width (Ws) of each second groove, whereby the width (Wc) of the first groove is around the threefold of the width (Ws) of the second groove.
A thermally insulated pipe system comprising a pipe having an outer diameter and a thermally insulating pipe section mounted on said pipe, said pipe section comprising two longitudinal parts each having a longitudinal opening, providing an aperture for accommodating the pipe whereby the two longitudinal parts are facing to each other in a symmetry plane,
- wherein
- two webs are provided in each longitudinal opening of the parts, each web extending substantially up to the symmetry plane and being arranged under an angle (α) between 45° and 90° relative to the symmetry plane, thereby incorporating a first groove between the webs and second grooves between each of the webs and a surface of the longitudinal opening, wherein each web has a width (Ww) being smaller than the width (Wc) of the first groove.
A thermally insulating pipe section comprising two longitudinal parts each having a longitudinal opening, providing an aperture for accommodating a pipe, whereby the two longitudinal parts are facing to each other in a symmetry plane, wherein two webs are provided in each longitudinal opening of the parts, each web extending substantially up to the symmetry plane and being arranged under an angle (α) between 45° and 90° relative to the symmetry plane, thereby incorporating a first groove between the webs and second grooves between each of the webs and a surface of the longitudinal opening, wherein the webs are rectangular in cross-section and wherein the second grooves are trapezoidal in cross-section.
A method for producing a thermally insulating pipe section comprising two longitudinal parts each having a longitudinal opening, providing an aperture for accommodating a pipe, whereby the two longitudinal parts are facing to each other in a symmetry plane, wherein a first groove between two webs and second grooves between each of the webs and a surface of the longitudinal opening are cut into each longitudinal opening of each part by using a rotatably driven tool which tool is relatively moved to the part thereby forming both webs extending substantially to the symmetry plane and being arranged under an angle (α) between 45° and 90° relative to the symmetry plane, and such that each web has a width (Ww) that is smaller than the width (Wc) of the first groove.
