Cylindrical tubular element comprising a frusto-conically shaped press fit connection

A system of tubular elements for use in a temperature control and/or transport system of a horticulture field or greenhouse that comprises a plurality of spaced apart and parallel arranged longitudinal linear tubes, wherein the system comprises at least two interconnected tubular elements,

• wherein said first tubular element is connected at a first end section of the first longitudinal tubular element to the second tubular element at a second end section of the second tubular element;
• wherein the respective first end section of the first tubular element is a frusto-conically shaped end section, wherein, as seen along a longitudinal axis of the first end section, an outer diameter of the frusto-conically shaped end section decreases towards the first outer end of the first tubular element;
• wherein the respective second end section of the second tubular element is an inverted inner frusto-conically shaped end section, wherein, as seen along a longitudinal axis of the respective second end section, an inner diameter of the frusto-conically shaped end section increases towards the second outer end of the second tubular element;
• wherein said inverted inner frusto-conically shaped end section of said second tubular element is arranged to receive the frusto-conically shaped end section of the first tubular element for forming a connection section, such that the first and second tubular elements are mechanically interconnected at the connection section by insertion of the frusto-conically shaped end section of a first tubular element into the inverted inner frusto-conically shaped end section of the second tubular element,
• wherein at least one longitudinal linear tube of the plurality of spaced apart and parallel arranged longitudinal linear tubes comprises said respective first and second tubular elements, wherein said first and second tubular elements are longitudinal tubular elements having a respective central longitudinal axes that coincided and align with the respective longitudinal axes of the respective end sections, such that the respective central longitudinal axes of the first and second tubular elements align and coincide for, at least partly, forming said at least one longitudinal linear tube, wherein, at the start of the frusto-conically shaped end section, the outer diameter is reduced such that a maximum outer diameter of the frusto-conically shaped end section is smaller than the outer diameter of a central section of the tubular element, wherein said central section is in between the first end section and the opposite second end section of the tubular elements, wherein said at least one longitudinal linear tube has a substantially constant outer diameter over substantially the full length of the respective longitudinal linear tube.
