Embodiment Construction

[0038] In the drawings, the same reference numerals designate similar parts.

[0039] Reference is made to Figure 1 which schematically shows an outer tubular element 1 extending along a longitudinal axis A. The outer tubular element 1 has, on its first and second ends, first connecting flanges 3 and 6 protruding outwards. For drawing purposes, the outer tubular element 1 is shown as a single part, but in practice it is common practice to weld the flanges to straight pipe pieces.

[0040] Near the first and second ends, the first and second parts 9, 12 are respectively formed with cylindrical inner walls. The first and second portions 9, 12 are axially offset from each other and the inflation fluid inlet 15 traverses the wall of the outer tubular element 1 between the first and second ends. Inlet 15 is connected to flange 17 for fluid connection to a source of pressurized inflation fluid.

[0041] FIG. 2 shows an inner tubular element 20 which may be arranged in the outer t...

Abstract

A pipe part ( 100 ) for conveying a solid particulate material, comprising an outer tubular element ( 1 ) stretching along a longitudinal axis (A) and having first ( 9 ) and second ( 12 ) sections axially displaced from each other. An inner tubular element ( 20 ) is disposable inside the outer tubular element ( 1 ) and adapted for longitudinally conveying the solid particulate material from one end to another end. The inner tubular element ( 20 ) comprises an aeration-fluid-permeable wall part ( 23 ), and is sealingly connected with-and flexibly supported by-the first and second sections ( 9,12 ) to form an aeration fluid distribution chamber ( 40 ) between the first and second sections ( 9,12 ) and the inner ( 20 ) and outer ( 1 ) tubular elements. The aeration fluid distribution chamber ( 40 ) is provided with an aeration fluid inlet ( 15 ) to define an aeration fluid flow path ( 19 ) between the aeration fluid inlet ( 15 ) through the aeration-fluid-permeable wall part ( 23 ) via the aeration fluid distribution chamber ( 40 ).

Description

technical field [0001] The present invention relates to pipes for conveying solid particulate material. Background technique [0002] Examples of pipes suitable for conveying solid particulate material at low to moderate pressures (ie up to around 15 bar) are described in US 6,227,768, DE 12,69,571 and WO 2004 / 087331. [0003] The pipe disclosed in US 6,227,768 comprises an inner pipe adapted to convey particulate material from a first end of the pipe to a second end and having a gas permeable wall, the inner pipe being arranged longitudinally over an outer pipe having an impermeable wall middle. The outer pipe is provided with inwardly projecting seal support rings within the first and second ends, wherein the inner pipe is rigidly secured to the outer pipe such that the gas distribution chamber is located between the outer pipe, the inner pipe and the outer pipe. between the inner protruding seal support rings. A compressed gas intake nozzle traverses the outer conduit,...
