What’s the Working pressure range of pipeline rubber bellows in heating piping systems？
Shanghai Songjiang Group Introduce to you: Information of Working pressure range of pipeline rubber bellows in heating piping systems. The working pressure of the pipeline rubber bellow of the heating pipeline system is 1.0MPa and 1.6MPa. If there are special high pressure requirements, we can also specially design.
Pressure range: The pressure of various pipeline rubber bellow is the design pressure Pd (MPa) when T=20℃. General pressure range of pipeline rubber bellow for heating piping systems is 1.0MPa to 1.6 MPa. Before each product leaves the factory, each process is subjected to 99.5 pressure test and other required testing, and can only leave the factory after meeting the standard requirements.
Before installation, loosen the anchor bolt of the clutch pressure plate, drag it to the installation length, then tighten the anchor bolt of the clutch pressure plate diagonally to avoid pressure deviation, and then connect the goods on both sides. It should be installed in the middle of the two support frames on the parallel line of the pipeline to prevent it from being pulled off. The adopted countermeasures, when selecting elbow heating pipes, the design scheme should take into account the cold tightness during assembly. Cold tightness index can be used as 0.5. When selecting, the installation length under various installation temperatures should be calculated, and the compensation capacity of not less than 20mm should be reserved for the pipeline under the likely high and low temperatures.
Pipeline rubber bellows can avoid excessive offset of pipelines and lead to leakage or damage of compensation joints. It is mainly used for pipeline connections that absorb radial movement and bearing force driving force. It is suitable for connecting with flanges and welding with pipelines at the same time. According to the installation length, the top angle is symmetrically twisted to cover the anchor bolts, and then the nut is adjusted, so that the pipeline can be expanded arbitrarily, and the expansion can be locked to ensure the reliable operation of the pipeline.
