The importance of alloy steel pipes in metal hoses and corrugated compensators

- Jan 17, 2019-

Compared with the lubricating pipe, the alloy steel pipe with the same wall thickness has three characteristics: the radial stiffness of the former is much larger than that of the latter; the axial stiffness of the former is much smaller than that of the latter; the bending stiffness of the former is also higher than that of the latter. Much smaller. For this reason, corrugated pipes are used to make metal hoses and corrugated compensators.

The size of each stiffness of the alloy steel pipe is a very important parameter in engineering design. It is used to make metal hoses, which are related to the driving force of the device and working conditions; for dry corrugated compensators, it relates to the rigidity of all piping systems and the strength design of the fixed bearings.

If the load accepted by the alloy steel pipe is a lateral force or a moment that is flat and inward in the axial direction, its working characteristics depend on the bending rigidity. In order to determine its bending stiffness value, its peak semi-arc and trough semi-arc is regarded as a rigid joint, and the disordered force is a simple force mode, and the disc warping theory is used as the base.

Alloy steel pipes have high pressure resistance and high rigidity, so they can be used in metal hoses and corrugated compensators to reduce losses and add benefits.
