Valve and the connection seems like only choose compensator four-ball rubber joints, so that no matter where low temperature resistant rubber joints, as long belongs to a class of pipe fittings can be used to connect compensation work. When compensation is applied to the metal pipe of the engine exhaust system, high temperature gas flows through the media, so the majority of the metal compensator design uses rigid seal structure will compensate connected in the pipeline. But the metal compensator seal is what structures it? Today, let Serco technician to tell you this knowledge of it. If we want to know their quality rubber joints just can not see with your eyes, because it requires a certain skill to see the rubber joint quality is excellent or poor quality Rao tetrafluoroethylene rubber joints, so today let Serco Technical staff to tell you: identify knowledge inferior rubber joints from several aspects of it. We want to know whether it is inferior rubber joints, one that we can judge from the rubber ball joints, because the ball during the production of production when there will be inflatable and dura mater, and because these two films feel different and There are some differences, but if there is a sphere of shadow magic words, or do not choose the way of making the rubber joints, so the effect is not very ideal dura, which is the rubber joints inadequacies of this aspect; deflection rubber expansion joints, rubber joint , Serco supply materials provided by Serco Gongyi City Water Supply Materials Co., Ltd.
