Description
Description L'invention est relative à une tuyauterie industrielle double enveloppe destinée au transport de pulvérulents et autres solides abrasifs destiné à retarder le percement de l'enveloppe extérieure de la tuyauterie, permettant d'allonger la durée de vie des tuyaux et réduire les actions de maintenance des équipements industriels.Description The invention relates to a double-jacketed industrial piping intended for the transport of pulverulent and other abrasive solids intended to delay the piercing of the outer casing of the pipework, making it possible to extend the service life of the pipes and to reduce the actions of maintenance of industrial equipment.
Etat des sachant : L'état de l'art est caractérisé par : des tubes en aciers spéciaux anti-abrasion. Il s'agit de tubes simple enveloppe dont il convient que la qualité mécanique des matériaux puisse retarder le phénomène d'abrasion. Cette technologie résiste plus difficilement à une utilisation en milieu humide par rapport à un acier classique, ce qui en pratique ne permet pas d'augmenter la durée de vie du tuyau au regard d'aciers classiques. En effet les matériaux et composants à transporter sont souvent exposés à l'humidité atmosphérique, ce qui constitue un apport d'humidité à même de fragiliser les équipements dotés de technologies acier anti-abrasion. il existe également des tuyauteries dans lesquelles sont déposées, sur les faces intérieures par un procédé de soudage, des matériaux durs apportés pour résister à l'abrasion. Ces équipements sont réputés pour leur tenue mais nécessitent des coûts d'investissement importants. selon le même principe de protection d'enveloppe simple, celle-ci reçoit des matériaux qui sont collés, ce qui constitue un blindage intérieur de la tuyauterie. Les coûts de mise en oeuvre de cette technologie sont encore plus importants que pour la tuyauterie avec procédé de renfort par soudage.State of the art: The state of the art is characterized by: special anti-abrasion steel tubes. These are single-walled tubes whose mechanical quality of materials should be able to delay the phenomenon of abrasion. This technology is more resistant to use in a wet environment than conventional steel, which in practice does not increase the life of the pipe compared to conventional steels. In fact, the materials and components to be transported are often exposed to atmospheric humidity, which constitutes a contribution of moisture that can weaken the equipment equipped with anti-abrasion steel technologies. there are also pipes in which are deposited on the inner faces by a welding process, hard materials made to resist abrasion. These devices are known for their outfit but require significant investment costs. according to the same principle of simple envelope protection, it receives materials that are glued, which constitutes an inner shield of the pipe. The costs of implementing this technology are even greater than for piping with welding reinforcement.
En matière de tuyauterie double enveloppe, une technologie existe en ce que l'espacement entre les tubes est comblé par un apport de béton qui apporte une pérennité aux ouvrages, mais est limité dans son usage en raison de son poids qui limite son usage en lieu et place des tuyauteries existantes.In the case of double-jacketed piping, a technology exists in that the spacing between the tubes is filled by a supply of concrete which brings durability to the structures, but is limited in its use because of its weight which limits its use in place and place existing piping.
Description de l'invention L'invention est relative à une tuyauterie industrielle double enveloppe destinée au transport de pulvérulents et autres solides abrasifs destiné à retarder le percement de l'enveloppe extérieure de la tuyauterie, caractérisé par :Description of the Invention The invention relates to double-jacketed industrial piping intended for the transport of pulverulent and other abrasive solids intended to delay the piercing of the outer casing of the pipework, characterized by:
Un tube extérieur (a)An outer tube (a)
Un tube intérieur (b) - Un espacement (c) de diamètre constant entre ces deux tubes et en tout point de leur longueur,An inner tube (b) - A spacing (c) of constant diameter between these two tubes and at every point of their length,
Des éléments séparatifs (d) au sein de l'espacement sus dit aux fins de constituer des cloisons étanches (d) au passage des pulvérulents continues et régulières sur toute la circonférence intérieure du tube extérieur,Separating elements (d) within the aforesaid spacing for the purpose of constituting watertight partitions (d) to the passage of continuous and regular powdery materials over the entire inner circumference of the outer tube,
Ces éléments séparatifs (d) sont constitués d'une bague pleine (non ajourée) ayant pour diamètre intérieur le diamètre extérieur du tube intérieur, et comme diamètre extérieur le diamètre intérieur du tube extérieur.These separating elements (d) consist of a solid ring (not perforated) having the inner diameter of the outer diameter of the inner tube, and as outer diameter the inner diameter of the outer tube.
Ces mêmes éléments séparatifs (d) sont disposés de façon régulière sur toute la longueur des deux tubes de façon à constituer des chambres d'isolement (e) sur toute la périphérie de la tuyauterie.These same separating elements (d) are arranged regularly along the entire length of the two tubes so as to constitute isolation chambers (e) on the entire periphery of the pipework.
La tuyauterie double enveloppe a un poids contenu, en raison que l'espacement (c) entre les tubes est vide, ce qui permet de l'installer en lieu et place de la tuyauterie existante sans obérer de contraintes mécaniques sur les supports.The double jacketed piping has a contained weight, because the spacing (c) between the tubes is empty, which allows it to be installed in place of the existing piping without burdening mechanical stresses on the supports.
Selon cette technologie et à l'usage, lorsque la tuyauterie est en service :According to this technology and in use, when the piping is in use:
Le pulvérulent abrasif circule dans la tuyauterie, ce qui engendre avec le temps (usage intense continu) une usure de l'enveloppe intérieure (f) pouvant aller jusqu'au percement de celle-ci, - Dans ce cas la chambre d'isolement (e) va se remplir d'une partie de produit transporté qui sera bloquée dans l'espacement inter-tube (c) afin de former un écran entre le produit transporté et l'enveloppe extérieure, - Le pulvérulent emprisonné (g) formant l'écran de protection du tube extérieur, ses caractéristiques mécaniques étant plus résistantes que celles du tube intérieur, permet d'allonger la durée de vie de la tuyauterie.The abrasive powder flows in the pipework, which generates with time (continuous heavy use) wear of the inner casing (f) up to the piercing thereof, - In this case the isolation chamber ( e) will fill with a portion of transported product which will be locked in the inter-tube spacing (c) to form a screen between the transported product and the outer shell, - the trapped powder (g) forming the protection screen of the outer tube, its mechanical characteristics being more resistant than those of the inner tube, allows to extend the service life of the piping.
