Zusammenfassung:The invention relates to a pig routing insert or drain used in various underwater systems comprising a block structure, for example block manifolds, with a plurality of perforated fluid passages. The insert generally comprises a substantially unrestricted flow opening adapted to allow the substantially unrestricted flow of fluid and the passage of a cleaning pig, and a partially restricted opening comprising at least one pig blocking structure, in which the partially restricted opening is adapted to allow the substantially unrestricted flow of fluid through the partially restricted opening whilst blocking the passage of a cleaning pig through the partially restricted opening. Also disclosed is a new method for manufacturing and installing the pig routing insert or drain in a machined block manifold. L'invention concerne un insert ou drain d'acheminement de racleur utilisé dans divers systèmes subaquatiques comprenant une structure en bloc, par exemple, des manifolds en bloc, présentant une pluralité de passages de fluide perforés. L'insert comprend généralement une ouverture de flux sensiblement non restreint adaptée pour permettre le flux de fluide sensiblement non restreint et le passage d'un racleur de nettoyage, et une ouverture partiellement restreinte comprenant au moins une structure de blocage de racleur, l'ouverture partiellement restreinte étant adaptée pour permettre le flux de fluide sensiblement non restreint à travers l'ouverture partiellement restreinte tout en bloquant le passage d'une racleur de nettoyage à travers l'ouverture partiellement restreinte. L'invention concerne également un nouveau procédé pour la fabrication et l'installation de l'insert ou drain d'acheminement de racleur dans un manifold en bloc usiné. "INSERTO DE ROTEAMENTO DE PIG ADAPTADO PARA INSTALAÇÃO EM UMA ESTRUTURA, ESTRUTURA E MÉTODO" A invenção trata de um inserto ou dreno de roteamento de pig utilizado em diversos sistemas subaquáticos compreendendo uma estrutura de bloco, por exemplo, manifoldes de bloco, com uma pluralidade de passagens de fluido perfuradas. O inserto geralmente compreende uma abertura de fluxo substancialmente irrestrito adaptada para permitir o fluxo de fluido substancialmente irrestrito e a passagem de um pig de limpeza, e uma abertura parcialmente restrita compreendendo pelo menos uma estrutura de bloqueio de pig, em que a abertura parcialmente restrita é adaptada para permitir o fluxo de fluido substancialmente irrestrito através da abertura
