The composition of pipe expansion fittings.
Telescopic pipe equipment material selection for heating pipe network of corrugated pipe material selection, should be considered in addition to the working medium, operating temperature and external environment, also should consider the possibility of stress corrosion, such as water treatment agent and the influence of the pipeline cleaner on the material, on the basis of combination of corrugated pipe material welding, molding and the performance of the material cost, optimizing the economic and practical ripple control of materials, selection of materials for heating pipe network of corrugated pipe material selection, should be considered in addition to the working medium, operating temperature and external environment, also should consider the possibility of stress corrosion, water treatment and the influence of the pipeline cleaner on the material, etc., and on the basis of the combination of corrugated pipe material welding, forming and material performance and low cost, optimizing the economic and practical corrugated materials were made.
Stainless steel bellows expansion of the pipe as a flexible pressure pipe fittings installed in the liquid delivery system, to compensate for pipe or machinery, equipment to connect the displacement of each other, to absorb vibration energy and can rise the vibration damping, sound attenuation, etc, has good flexible, lightweight, corrosion, fatigue resistance, high and low temperature resistance and so on many characteristics of stainless steel corrugated pipe is used to use corrugated compensator of the elastic element of effective telescopic deformation to absorb piping, pipe or container by the reason of heat bilges cold shrink the size change of a kind of compensation device, belongs to a kind of compensating element, for axial, lateral and angular displacement of the absorption, corrugated compensator connection mode can be divided into flange connections and welding two welding methods commonly used directly buried pipeline compensator (except trench installation) the reliability of the metal corrugated compensator is by the design, manufacture, installation and operation management, and other links.
Reliability of stainless steel bellows is by the design, manufacture, installation and operation management, and other links, considering reliability should also from these aspects, selection of materials for corrugated pipe material selection, heating pipelines should be considered in addition to the working medium, operating temperature and external environment, the force should also be considered the possibility of corrosion, water treatment in class and pipe cleaner on the material, etc., the influence of expansion pipe and pipe on the basis of the combination of corrugated pipe material welding, molding and the performance of the material cost, optimizing the economic consequences of the use of corrugated materials were made.
