>< Rectangular fillet compensator (waveform) r/ br />
An overview
Rectangular fillet
Rectangular fillet compensator (waveform) is determined according to the nominal diameter specification of the rectangular pipe. Due to the limitation of the bellows fillet, the small diameter specifications have been deleted from both the full height and half height, and are cataloged as follows:

When the installation temperature is higher than the minimum temperature of the pipeline Yes, a pre-tension amount lower than % can be made, usually
The pre-tension amount percentage﹛(minimum installation temperature/minimum operating temperature)﹜%
The axial compensation amount of multi-wave products is equal to the single-wave axial compensation amount multiplied by the number of waves.
A single rectangular fillet compensator cannot absorb radial displacement. When it is necessary to absorb radial displacement, two rectangular fillet compensators or a three-dimensional compensator are often used, or contact the manufacturer for non-standard design.

Single wave axial stiffness of bellows
The single-wave axial stiffness of the full-height corrugated pipe is (+B+/, where B is the outer diameter of the rectangular pipe (unit: ), and is the temperature-to-stiffness correction coefficient, see the table below.
The single-wave axial stiffness of half-height corrugated pipe is (+B+/

Application of compensator in various fields of life
The rapid development of the times requires many traditional tools and equipment to be updated. Compensators are widely used in various fields of life. They can also be called pipe compensators, corrugated compensators, etc., and are often used in In the industrial field, it helps to support combustion and form high temperatures required by certain industries. In order to facilitate people's daily life, compensators have been greatly improved.
In terms of appearance, in order to facilitate people's daily use, the non-metallic design is also very user-friendly. Industrial production is very complex to a large extent. Without corresponding machinery and equipment, it is difficult to complete large-scale industrial production. With the rapid development of economy, industrial development has become stronger and stronger. As a good helper in industrial production, the role of compensator cannot be underestimated. According to its different functions, people apply it in many environments such as production and life. The use of compensator can support combustion and generate high temperatures at the fastest speed. In the early days, it was often used in metallurgy.
In ancient times, high-tech industrial production tools like today had not yet been invented. Our ancestors could only use fan blowpipes and leather bags to support combustion and create high temperatures. However, this not only consumes physical strength, The wind flow and wind power obtained are also very small, making it impossible to engage in basic production. With the development of the times and science and technology, the emergence of compensators has greatly facilitated people’s daily lives
