Product Description
Performance characteristics of rectangular metal bellows expansion joint:
the material of rectangular metal bellows expansion joint is usually made of koaton steel or stainless steel, which is characterized by large section, low pressure, high temperature and optimized waveform. It is mainly used for conveying gas or dust gas pipeline and fan outlet to absorb displacement or shock absorption.
Angle structure of rectangular metal bellows expansion joint:
application and working conditions will determine the correct structure and angle structure of rectangular metal bellows expansion joint.
Under the condition of low pressure, rectangular metal expansion joint with V-shaped angle structure can be used. The U-shaped structure is the most suitable for high pressure environment.

Rectangular metal bellows expansion joint - single bevel V-shaped structure:
This is the most common and economical form of construction for thermal expansion and is easy to be bolted or welded to pipes. It is preferred for low cycle and vibration free applications.

Rectangular metal bellows expansion joint - double bevel V-shaped structure:
The production cost of this kind of angle structure is slightly higher than that of single angle structure. However, it can provide longer cycle life under the same operating conditions.

Rectangular metal bellows expansion joint mirror angle V-shaped structure:
This type of structure is mainly used for low voltage applications. This structure is characterized by good cycle life and is superior to the double bevel design

Rectangular metal bellows expansion joint - U-shaped structure with rounded corners:
In application, if the pressure reaches 2 PA, and vibration and cycle life are important factors, this structure can be considered. The expansion joint with fillet structure is the most expensive in production cost.

Application scope of rectangular metal bellows expansion joint:
Rectangular metal expansion joint, exhaust system of gas turbine, connection part of turbine or condenser, exhaust port of water heater, seal of pressure ventilation fan, exhaust pipe, AC heat exchanger, precipitator and other steam and large pipe system.
Design considerations of rectangular metal bellows expansion joint:
It is very important to specify the axial displacement of the expansion joint to indicate the direction of displacement applied to the expansion joint, especially for large rectangular pipes.
When the transverse displacement is applied to the "key parts", it should be matched with the same amount of axial displacement, which is better than only the transverse displacement applied to the "non key parts"
The effect of this situation is much better. In many cases, a long compound rectangular metal expansion joint is the only practical solution. Moment
The range of raw material selection for U-shaped metal expansion joint is very wide, including 300 series austenitic stainless steel and high nickel alloy.
