Bearing Capacity Of Thick-walled Seamless Steel Tubes

The outstanding feature of thick-walled seamless steel pipe is its strong pressure resistance, and it can be transported by various liquids and gases. So how is the carrying capacity of thick-walled seamless steel pipes improved? The following is a detailed introduction for everyone.

In layman's terms, thick-walled seamless steel tubes can carry weight indirectly. It is generally believed that cabinets are also best not to hang on light-weight walls, but for light-weight walls that have been tiled, because cement can enhance the load-bearing capacity of the wall, the cabinet can be hung on the wall even without special treatment. . However, for the sake of insurance, it is best to deal with the wall. The method of treatment is to first coat a thick-walled seamless steel pipe on the wall, then smooth it with cement mortar, and finally seal it with gypsum board.

However, the safest method is to use a special hanger to secure the thick-walled seamless steel cabinet to the floor. Thick-walled seamless steel tubes carry relatively high pressure and are widely used in the construction bottom and transport liquids. From the perspective of his performance, the demand for thick-walled seamless steel tubes and the market will become stronger and stronger. Here are some reasons why thick-walled seamless steel pipes often burst:

1. The hot-rolled rolling position of thick-walled seamless steel tube steel is 38, 118m away from the strip head, mainly located in the middle of the strip.

2. It is speculated from the shape of the large hole of the rolling crack that the crack starts in the middle of the width of the strip. The reason is that the rolling force and the shearing force cause the crack to stretch and form a macroscopic macroscopic hole.

3. The seamless steel pipe in the cold rolling production process interrupted the fracture surface smooth, no obvious surface defects before and after the fracture.

4. Observing the microscopic morphology of the fracture, the typical dimple-like ductile fracture morphology is observed. At the same time, the fracture is layered, the central dimple is larger, the dimple is reduced at the near surface, and the crack exhibits divergence mainly center fracture. The extended fracture morphology has a deep fracture depth at the center, and it is speculated that the layered morphology of the fault zone is closely related to the central segregation.
