Rectangular fillet compensator

Rectangular fillet compensator is an elastic compensation element that can be freely expanded and contracted. It has compact structure, reliable operation, low cost, strong practicability, and has the functions of shockproof, dustproof, and maladjustment prevention. It is mainly used in the Yanfeng system of power station boilers, and is also suitable for similar smoke and air connection pipes in other industries such as metallurgy and chemical industry. . The design can be made according to different requirements into a single-piece expansion joint that mainly absorbs thermal displacement. Two expansion joints can also be used to form a toggle-type expansion joint to absorb three-dimensional thermal displacement in space, which can supplement the displacement caused by the thermal expansion joint. It is an indispensable and important component to ensure the safe and reliable operation of the pipeline system without causing damage and leakage of the pipeline. Due to the limitation of the bellows fillet, the small diameter specifications have been deleted from the full height and half height. For specifications or wave numbers outside the series, separate orders can be made from the manufacturer. Features of rectangular fillet compensator:
The arc steel plates at the corners of this product are welded and reinforced, and the interface is made of channel steel as structural parts, which enhances the structural rigidity of the product, and the overall product has smooth lines and a bright appearance.
b This product reduces the thrust of the pipeline system without losing overall stability and maintaining basic working stiffness, improves the thermal compensation capability of the product, and reduces the investment cost of flexible parts in pipeline construction.
Due to the adaptive change of the geometric shape, this product can work reliably in a benign force system under the action of external tensile stress, compressive stress and alternating stress, avoiding local stress risk areas. When working in an atmosphere, the deterioration trend of stress corrosion cracking and corrosion fatigue fracture () is effectively improved, and the allowable number of thermal cycles of the product is increased without affecting the service life.
When this product is welded to corrugated pipes, the weld seam can be far away from the arc tangent point. When the length of one side of the rectangle is less than 1, one weld seam can be reduced, and the misalignment of the weld seam is greatly reduced, and the corrugation occurs at any position of the product. The error between the tube cross-section shape and the length of the corrugated package is extremely small, and the corrugated forming and stretch-bending forming have a plump and smooth surface. It complies with the theoretical criteria for a good maximum value of bellows fatigue life.
The corners of this product are formed by large arc transitions to form a rectangular cross-section. The stress level of the corners is reduced, eliminating deformation dead corners and uniform deformation of the product during online operation, thus reducing the risk of regional high stress damage and prolonging the service life. Product life.
