Line Rod Lean Tube has another name, it is multiple-unit tube. There are 3 materials in industry: wire rod, stainless steel tube, aluminum alloy lean tube. We can also call them, which are the first generation, the second generation, the third generation lean tube in industry. Today I will emphatically introduce everyone about standard of bearing strength of line rod lean tube. It is convenient to everybody has data reference to purchase lean tube and organize bench car finished products.
The standard of the first generation and the second generation lean tube strength data test.
Condition: the first, the two sides of tube should fix and apply a concentrated load at the arrow. The second, tube strength is including internal dimensions of fittings.
Recommend to use: the bending height of the middle part of the material is 5/1000 of the length of the pipe.
Limit load: the load on which the pipe begins to undergo plastic deformation.
When the recommended load is exceeded, please control the load within 80% of the limit load.
When the sliding load of the connector is less than the recommended service load and the limit service load, mark the sliding load of the connection. (Green)
The third generation lean pipe strength data monitoring standard.
Conditions: the first, both ends of the pipe are fixed, and a concentrated load F is applied at the arrow. The second, the length of the pipe shall be the internal size including the connector.
Recommended load: a load whose bending height of the middle part of the pipe is 5/1000 of the length of the pipe.
Limit load: the load on which the lean pipe begins to undergo plastic deformation.
When exceeding the recommended load, please control the load within 80% of the limit load.
When the sliding load of the connector is less than the recommended load and the limit load, the sliding load of the connector shall be marked. (Green)
