[00043] As abas de união entre as partes do contra flange possuem um sistema de guia cilíndrica (rebaixo-ressalto) (17) que limita o deslocamento entre as partes1. The joining flaps between the counter flange parts have a cylindrical guide system (shoulder) (17) which limits the displacement between the parts 1 .
Instalação Installation
[00044] K instalação deve ser feita seguindo os seguintes passos : [00044] K installation should be done by following these steps:
- Preparação da ponta. - Tip preparation.
[00045] Esmerilhar cuidadosamente uma faixa de aproximadamente 25mm de largura na zona onde será realizado o cordão de solda. Este trabalho não deve afetar. a espessura d ponta. Carefully grind a strip approximately 25mm wide in the area where the weld bead will be made. This work should not affect. the thickness of the tip.
- Aplicar cordão de solda. - Apply weld bead.
[00046] Com auxilio de anel de cobre a montante da posição do
cordão de solda aplicar solda de forma a se obter ura cordão uniforme e ortogonal com a geratriz da ponta. O cordão deve ser realizado em apenas ura passe. Constam nas tabelas abaixo, dimensões e posição do cordão de solda: With the aid of a copper ring upstream of the position of the weld bead apply weld to obtain a uniform and orthogonal bead with the tip generator. The cord should be made in one pass only. The following tables show the dimensions and position of the weld bead:
[00047] Ao término da aplicação do cordão de solda, realizar escovação e limpeza. A pintura deve ser reconstituída na região afetada. Utilizar na primeira camada tinta rica em. zinco-, para segunda camada utilizar tinta betuminosa de base asfáltica e/ou epóxi correspondente.
~ Posicionar anel de trava. [00047] At the end of the weld bead application, perform brushing and cleaning. The paint should be reconstituted in the affected region. Use in the first layer paint rich in. zinc-, for the second layer use asphalt based and / or epoxy bituminous paint. ~ Position lock ring.
[00048] Como o diâmetro interno do anel de trava é inferior ao diâmetro externo do cordão de solda, é necessário abri-lo com auxilio de uma cunha (18) introduzida na descontinuidade do anel de trava. Since the inside diameter of the locking ring is smaller than the outside diameter of the weld bead, it must be opened with a wedge (18) inserted into the discontinuity of the locking ring.
- Montar ponta e bolsa. - Mount tip and bag.
[00049] Inserir anel de borracha dentro do alo amento da bolsa aplicando um esforço radial até que o anel se acomode em seu aloj amento . Insert a rubber ring into the pocket of the bag by applying a radial effort until the ring fits into its housing.
[00050] Aplicar camada de pasta lubrificante na superfície visível do anel de borracha e também na ponta do tubo ou conexão . Apply layer of grease to the visible surface of the rubber ring and also to the end of the pipe or fitting.
[00051] Para a montagem efetiva dos tubos, centrar a ponta na bolsa e manter a tubulação apoiando-o sobre dois calços de madeira. Introduzi a ponta dentro da bolsa, observando alinhamento e nivelamento. 0 espelho da bolsa deverá ficar a uma distância de aproximadamente lera do cordão de solda, [00051] For effective pipe assembly, center the tip in the bag and keep the pipe resting on two wooden shims. I inserted the tip into the bag, noting alignment and leveling. The pocket mirror should be approximately 1 l from the weld bead,
- Montar contra flange. - Mount against flange.
[00052] Encaixar as duas metades do contra flange conforme abaixo : Fit the two halves of the counter flange as follows:
[00053] Montar parafusos, arruelas e porcas. Para o aperto deverão ser utilizadas chaves do tipo "soquete". [00053] Mounting screws, washers and nuts. For tightening, "socket" type wrenches should be used.
[00054] Em um primeiro instante é normal a folga entre o contra flange e os pontos de trava da ponta e da bolsa. Apenas após a aplicação de pressão na linha é que os contatos entre as partes
16000150 [00054] At first the clearance between the counter flange and the locking points of the tip and the pocket is normal. Only after line pressure is applied do the contacts between the parts 16000150
12 12
de tratamento serão efetívamente realizadas. treatment will be effectively carried out.
[0005-5] Defletir, se necessário, no limite de ângulo admissível, somente após montagem completa do contra flange. Deflect, if necessary, within the permissible angle limit only after complete mounting of the counter flange.
[00056] Em' uma modalidade alternativa à bipartição do contra flange, existe a possibilidade de divisão do mesmo em um número maior de setcres para facilitar a fabricação, o manuseio e a instalação em tubulações de maior diâmetro, mas especificamente em. diâmetros maiores que 400 mm. [00056] By "an alternative embodiment the splitting of the counter flange, there is a possibility of dividing it into a greater number of setcres to facilitate manufacturing, handling and installation in larger diameter pipes but specifically. diameters greater than 400 mm.
Neste ponto, faz-se necessário salientar que o contra flange bipartido pode se aplicado a qualquer diâmetro de tubulação, inclusive os maiores, a modalidade alternativa ora abordada compreendendo uma outra abordagem do mesmo conceito inventivo, podendo ser uma opção eiu determinados projeto.s. At this point, it should be noted that the split flange can be applied to any pipe diameter, including the largest, the alternative embodiment now approached comprising another approach of the same inventive concept, and may be an option and / or certain designs.
Fundamentalmente a divisão em mais de dois setores não traz diferenças significativas no conceito do invento. Permanece a proposta da substituição dos diversos parafusos constituintes da técnica anterior por travas integradas ao novo contra flange. Fundamentally the division into more than two sectors does not bring significant differences in the concept of the invention. The proposal remains for the replacement of the various prior art screws by latches integrated into the new flange.
Em relação aos constituintes da junta não há nenhuma diferença nos elementos necessários ao travamento. Permanecendo necessária a ponta e a bolsa com colar de trava de tubos ou conexões, o anel de trava, o cordão de solda, o anel de borracha e o contra flange. Regarding the joint constituents there is no difference in the elements required for locking. Remaining the tip and pouch with pipe locking collar or fittings, the locking ring, the weld bead, the rubber ring and the counter flange remain necessary.
A instalação também não possui diferenças. Todas as etapas seguidas para a montagem do contra flange bipartido também devem ser seguidas para a montagem da opção com mais divisões. The installation also has no differences. All steps followed for mounting the split split flange should also be followed for mounting the option with more divisions.
Contudo os contra flanges bipartidos para travamento de tubulações de diâmetros maiores podem apresentar pesos de certa forma
elevados para manuseio sem a utilização de máquinas para íçarnento. Para melhoria deste aspecto, o invento, ou seja, o contra flange pode ser dividido em mais de dois setores, trazendo assim menor peso a cada parte. Esta redução do peso promove uma grande melhoria no manuseio, tornando possível que operadores façam a instalação em campo sem o auxílio de máquinas para içamento. However, split flanges for locking larger diameter pipes may be somewhat high for handling without the use of lifting machines. To improve this aspect, the invention, that is, the counter flange can be divided into more than two sectors, thus bringing less weight to each part. This weight reduction promotes a major improvement in handling, making it possible for operators to install in the field without the aid of lifting machines.
A opção de mais divisões também traz benefícios à fabricação do contra flange. Peças menores e mais leves são mais fáceis de serem processadas, sofrem. alterações dimensionais menores além de necessitarem de maquínários mais simples para fabricação. The choice of more divisions also brings benefits to counter flange manufacturing. Smaller and lighter parts are easier to process, suffer. minor dimensional changes and require simpler machinery for manufacturing.
Sobre a modalidade alternativa, ilustrada pelas Figuras 16 a 18, tem-se que: Regarding the alternative embodiment, illustrated by Figures 16 to 18, we have:
As figuras 17a e 17b apresentam exemplos dé divisões em mais de dois setores. A figura (17a) demonstra um contra flange seccionado em quatro setores; enquanto que a figura (17b) demonstra um contra flange seccionado em seis setores. Figures 17a and 17b show examples of divisions in more than two sectors. Figure 17a shows a counter-flange sectioned in four sectors; while figure 17b shows a counter flange sectioned in six sectors.
A figura (18) apresenta os componentes para montagem do contra flange. Gomo pode ser visto é mantido a utilização dos parafusos (7), das arruelas (8), das porcas (9) e logicamente do contra flange (1) . Figure (18) shows the components for mounting the counter flange. As can be seen, the use of the bolts (7), washers (8), nuts (9) and of course the counter flange (1) is maintained.
