What are the types and applications of pipe compensators?

Pipe compensators I. Introduction to pipe compensators: Pipe compensators are classified into several major categories, including metal bellows compensators, non-metallic compensators, sleeve compensators, and square compensators. Metal bellows compensators and non-metallic compensators are widely used in practice. 　　1. A metal bellows compensator consists of the bellows, which is the main component that enables its operation (an elastic element), along with accessories such as end tubes, supports, flanges, and ducts. It belongs to a type of compensation component. It utilizes the effective expansion and contraction of its main working element, the bellows, to absorb dimensional changes in pipelines, conduits, containers, etc., caused by factors such as thermal expansion and contraction, or to compensate for axial, lateral, and angular displacements of such pipelines, conduits, and containers. It can also be used for noise reduction and vibration damping. It is widely used in modern industry. 　　2. Non-metallic compensators can compensate for axial, lateral, and angular displacements of pipes. They feature no thrust generation, simplified support design, corrosion resistance, high-temperature tolerance, as well as sound and vibration reduction properties, making them particularly suitable for hot air ducts and dust exhaust ducts. 　　II. Functions of pipe compensators: 1. To compensate for and absorb axial, lateral, and angular thermal deformations of pipes. 　　2. The expansion amount of the wave compensator facilitates the installation and removal of valves and pipelines. 　　3. Absorb equipment vibrations and reduce the impact of such vibrations on the pipes. 　　4. Absorb the deformation of pipelines caused by earthquakes and land subsidence.

Metallic compensators are mostly used in longer pipelines, in areas where temperature changes cause thermal expansion and contraction of the pipes. However, in many cases, the pipes are shaped into a U-shaped configuration as an alternative to compensators.

Most pipe compensators are made of metal. It is mainly temperature changes that cause the oil to vaporize, thereby increasing the pressure inside the pipes; excessive pressure can lead to cracking at welds, valves, and other areas, which is why U-bends or pipe compensators are used.

I would like to ask how the U-shaped bend is calculated for compensation purposes
