People often confuse rubber soft joints and insulated joints, thinking that the two are the same, but in fact the two are still different, not only the shape is different, but also the entire installation process is also different. People often confuse rubber soft joints and insulated joints, thinking that the two are the same, but in fact the two are still different, not only the shape is different, but also the entire installation process is also different. It is a pipe connector with buried steel pipe tightness, compressive strength characteristics and electrical corrosion resistance requirements and has specified insulation properties. It is composed of components, insulation plates, packing, sealing rings, short pipes, etc. In the steel pipeline yin-protection system software, the insulation layer flange is an alternative measure carried out according to the shortcomings in the application, and is an indispensable and important working pressure component in the pipeline yin-protection system software, which is widely used in the steel pipeline yin protection system.
The insulation connection structure is simple and the reliability is high. The installation of the insulation flange should not be buried, otherwise the overall insulation layer needs to be made to prevent corrosion. Gradually replace the insulated joints of the insulation layer flange. Carry out the insulation characteristics of insulation layer flange plate insulation rubber pad and high toughness insulation layer sleeve pad, and carry out insulation work on both sides of the flange pan. It has been applied in underground pipe valves for yin protection transmission and distribution networks and buried pipe valve wells that require potential differential block protection. After the insulation joint is docked with the pipeline, it shall not be suspended within 5 meters so as not to damage the insulation joint; when installed in the vapor material, the pipeline should not be installed in the low-lying place of the laying pipeline; the working pressure rate should not exceed 0.5CPa/min; after docking with the pipeline, the anti-corrosion treatment should be terminated according to the pipeline filling requirements, and the anti-corrosion actual operation should not be terminated. The surface temperature of the insulation node is higher than 100.
The combination of the glue soft joint and the spherical flange is one of the basic stages of the production and manufacture of the sphere, and whether this stage can smoothly carry out all the normal applications of the endangered sphere. Because the sphere in the entire assembly process, installation errors will lead to damage to the surface of the sphere or the surface of the sphere, now the DN150 type rubber soft joint has begun to slowly choose the semi-automated sleeve machine for production and processing, but the specifications above DN150 will still cause damage to the surface of the sphere, so the surface of the sphere still needs manual operation.
