Working conditions of oil-resistant double sphere pipeline rubber bellows
The double-sphere pipeline rubber bellow is mainly It is composed of a rubber sphere and flanges at both ends. The rubber is relatively soft, which can reduce vibration and noise, and can compensate for thermal expansion and contraction caused by temperature changes.
The wear-resistant and oil-resistant double sphere pipeline rubber bellow is a professional oil-resistant double arch spool pipeline rubber bellow specially used for desulfurization systems.
Generally, a large number of wear-resistant pipeline rubber bellows are used in the installation of dust pipelines and sandstorm systems, because general pipeline rubber bellows cannot meet engineering installation standards. Oil-resistant pipeline rubber bellows are composed of fabric reinforced rubber parts and flat pipe joints, loose metal flanges, or threaded pipe flanges, and are used for vibration isolation, noise reduction, and displacement compensation of pipelines. It is high elasticity, high air tightness, medium resistance, and weather resistance pipe joint.
According to the shape, it can be divided into concentric equal diameter, concentric reducer, and eccentric reducer. According to the structure: single ball, double sphere, elbow ball.
According to the connection form, it can be divided into flange connection, threaded connection, and threaded pipe flange connection.
According to the working pressure: 0.25MPa, 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa.
When installing, please pay attention to the working conditions. Please put the pipe fittings at both ends to be connected on a horizontal surface and lay them flat. When installing, you need to screw the thread structure into the lifting section of the pipe first, and then screw the other section of the pipe. , Always keep it on a horizontal plane to prevent the pipeline rubber bellow from tearing due to uneven force during the installation process. Next, tighten the screw thread by hand or a wrench to fix the pipe fittings at both ends of the screw pipeline rubber bellow box in an area that is not easy to stretch. or distorted objects. Oil resistance performance Choose the appropriate rubber material. Rubber has better resistance to long-term thermal oil aging performance in oxidized fuel at 125 ℃.
