Axial compound tie rod bellows

Product features of axial compound tie rod bellows:
The compound tie rod corrugated compensator has a simple structure and a large compensation amount. It is generally used in pipelines with low fatigue times and requiring large compensation amounts.
b The compensation amounts given in the sample are all axial compensation amounts at the number of fatigue damage times.
Flange connections are supplied according to machine standards, and can also be supplied according to national standards, chemical standards or other standards according to user requirements.
Axial compound tie rod bellows model:
Our company produces 3, pressure level
Connection method:, flange connection, pipe connection
Product axial compensation:
The force exerted by the axial compound tie-rod bellows on the fixed support: Pressure pushes the axial elastic force. In the formula:: Maximum working pressure or maximum test pressure: Effective area (check sample): Axial stiffness of metal expansion joint/: Metal expansion joint Axial compensation amount used: coefficient, when the corrugated expansion joint is pre-deformed, it is /, when the corrugated expansion joint is not pre-deformed, it is taken.
Application example of axial compound tie-rod bellows: a carbon steel pipe, nominal diameter, working pressure, maximum temperature of medium ℃, minimum temperature ℃, number of fatigue damage. The distance between the fixed supports of the required compensation pipes, the connection of the pipes, trial selection and calculation of the stress of the supports.

Structural features of axial compound tie rod bellows: Metal expansion joints are composed of two or three sections of bellows, short intermediate pipes, long tie rods and other parts, with a simple structure. Long tie rods are not load-bearing members. Precautions for installation and use of axial compound tie rod bellows: After the metal expansion joint (corrugated expansion joint) is installed on site, the nuts on both sides behind the ears must be retreated to the limit nuts. The axial compound tie rod bellows has a large compensation amount and is generally used in pipelines with low fatigue times and requiring a large compensation amount.
