Double spherical rubber joint type preparation method

The site installation of double spherical rubber joint should be neat and clean, and the installer must wear clean gloves. The installation of the branch pipe (sampling) on the pipeline requires that the prefabricated stage, the installation is completed and the sealed pipeline shall not be open work. Due to special circumstances, measures should be taken and quality control should be notified. As cutting, drilling and welding operations are carried out on the double spherical rubber joint, and the conditions of the operation are poor, it is likely that there will be relatively large metal cutting blocks and metal cutting or other foreign objects in the double spherical rubber joint, in addition to non-removable welding slag and cutting slag. Before the construction of double spherical rubber joints begins, professional engineers are responsible for submitting all relevant construction plans and making professional and technical presentations in each process before the operation of each process. The submitted program includes: clean pipe construction program, clean pipe welding program, endoscope inspection program, clean pipe pressure test program, pickling and passivation program, and no work shall be started without the completion of the program and handover before the process. Confirmation of welding samples of automatic argon arc welding machine.
Each specification of double spherical rubber joint should be made in advance to determine the welding parameters by making qualified welding samples before the official welding seam is welded. When welding the official seam, each specification of the double spherical rubber joint should be confirmed by opening and closing the sample welding parts, and the welding parameters of each part must be printed out on the automatic welding machine and kept in the corresponding welding parts. All pipelines, valves and pressure gauges are made of high quality double spherical rubber joints, and they are all standard fittings. All gas outlets are double spherical rubber joints.
