套筒补偿器是现代受热管网和设备进行热补偿(轴向、横向、角向位移)的关键部件之一,不能用来补偿角度偏差。 Guide: Sleeve compensator is one of the key components of modern heating pipe network and equipment for thermal compensation (axial, lateral, angular displacement), and cannot be used to compensate angular deviation. The thermal compensation performance of the compensator is determined by the bellows.

Sleeve compensator is one of the key components of modern heating pipe network and equipment for thermal compensation (axial, lateral, angular displacement), and cannot be used to compensate angular deviation. The thermal compensation performance of the compensator is determined by the bellows. The corrugated tube is allowed to undergo large changes under the action of axial force, lateral force and bending moment. As a thin-walled flexible element, its wave crest and trough part basically work in the plastic range. In addition to strength, stability, and fatigue life, there must be greater flexibility, and its stress distribution is much more complicated than that of vessels.
In the normal working process, the gravity of the piping system is required to be borne by various supports and hangers, so that the piping system can expand (shrink) freely; at the same time, the pre-deformation of the pipeline is often used to reduce the thrust of the pipe frame and enhance its stability These two points are particularly important in the process of new construction and renovation of the plant.
In the normal working process, the gravity of the piping system is required to be borne by various pipe racks (hangers). The mass of the corresponding flue of this device is 20t, which is borne by the constant force spring. During the reconstruction process, the piping system was rigidly fixed without resetting the constant force spring; due to the special nature of the constant force spring's displacement, it failed to return to its original state after the external load was removed. Therefore, after re-installation, the constant force spring is actually in a state of no force; when the rigid fixation is released, the mass of the flue is depressed, causing the pipe to move down and the expansion joint angle to become larger.
Since its establishment, Shanghai Luoying Pipeline Equipment Co., Ltd. has always pursued the business tenet of "survive by quality, develop by science and technology", the quality policy of "honesty, scientific and technological innovation, dedication and perfection" and a warm and thoughtful after-sales service system.
