1 Features Editing Features 1, the product unique structure, strong compression capability; 2, smooth wall, over flow; 3, the product easy to connect interface sealed, corrosion, zero leakage, no scaling, to avoid secondary pollution , is the ideal "green pipe"; 4, the product has a good flexural properties bellows prices, can be adapted to uneven soil subsidence; 5, long life, buried the use of up to 50 years; 6, light weight easy construction, reduce construction costs, shorten the construction period; geometry metal bellows 7, at a speed of 15 ft / sec, wear resistance 3-5 times higher than normal or fine steel 1. metal bellows tube Dimensions are according to the inner diameter of the series, typically metal bellows inner or outer diameter as the basic size, other structural parameters as the relative size. When the inner or outer diameter is determined, wall thickness, pitch, thick waves, etc., are determined on the basis of the inner or outer diameter of the appropriate proportion. Bellows design parameters to meet the performance requirements of the bellows, while also considering manufacturing processes and structural stability of the bellows. 1) deep wave coefficient k (also known as bulging coefficient) k is the wave depth coefficient than the outer diameter and the inner diameter of the bellows, which is to determine the geometry of the bellows is an important parameter. In the case of the inner diameter d determined, k value greater carbon bellows, the higher the height of the corrugations. k value affects the performance of the forming process of the bellows and bellows, formed bellows difficulty increases with k value increases. When the k value to 2, hydroformed bellows is quite difficult. So when k> = 2, should be welded bellows. Hydroformed bellows, can be divided into two kinds of light wave and dark wave to wave deep coefficient k = 1.5 as the cutoff bellows, k = 1.3 ~ 1.5 between the bellows, said shallow bellows, bellows forming easier; k = bellows between 1.6 to 1.9, said deep bellows, forming relatively difficult, sometimes twice shape. The same inner diameter of the bellows, deep bellows stiffness, high sensitivity, allowing large displacements; shallow bellows stiffness bellows specification, low sensitivity, allowing a smaller displacement. Bellows for measuring instruments, sensors, should adopt deep bellows; mainly used to bear the pressure bellows, bellows should be shallow. Wall bellows | two-out plastic (certified) | bellows provided by Xiong Zan Pair Ming plastic products factory.
