Abstract

"CENTRALIZADOR". Um centralizador para um tubo ou outro elemento alongado é formado a partir de uma pluralidade de corpos tubulares (16) cada qual tendo uma passagem de saída (23), os quais são conectados ponta a ponta de modo a formar uma passagem contínua. Cada um dos corpos tubulares (16) tem uma porção de conector fêmea (26) em uma extremidade e uma porção de conector macho (24) na extremidade oposta que se encaixa na porção de conector fêmea (26) com um jogo longitudinal e/ou angular. O meio de fixação na forma de um flange de montagem (14) é também provido de modo a fixar o centralizador com relação a um tubo em J através do qual o centralizador deve passar. A presente invenção centraliza o elemento alongado no tubo em J e mantém um raio de curvatura mínimo permissível, e ao mesmo tempo elimina ou reduz a níveis aceitáveis as cargas de contato e a abrasão sobre o elemento alongado. (Figura 1)."CENTRALIZER". A centralizer for a tube or other elongate member is formed from a plurality of tubular bodies (16) each having an outlet passageway (23) which are connected end to end to form a continuous passageway. Each of the tubular bodies (16) has a female connector portion (26) at one end and a male connector portion (24) at the opposite end that fits the female connector portion (26) with a longitudinal and / or angular. The mounting means in the form of a mounting flange (14) is also provided for securing the centralizer with respect to a J-tube through which the centralizer is to pass. The present invention centers the elongate member in the J-tube and maintains a minimum allowable radius of curvature, while at the same time eliminating or reducing contact loads and abrasion on the elongate member. (Figure 1).
