Matters needing attention in use of thick-walled steel pipe

Views: 2    

The wall thickness can be called a thick-walled steel pipe. There are some doubts about this. It depends on the ratio of the outer diameter of the steel pipe to the wall thickness of the steel pipe. For example, a steel pipe with a diameter of 50 mm, 10 mm can be regarded as a thick-walled steel pipe. However, for a diameter of 219 mm, 10 mm is only a thin-walled steel pipe. The basic definition of a thick-walled steel pipe lies in what customers call him. Note that when purchasing thick-walled steel pipes, the customer must clarify the material of the steel pipe and the length of the steel pipe, because this involves the number of machined parts and some waste.


Then there are the detailed dimensions of the inner and outer diameters of the steel pipe. This is to be counted inside because some parts need to be processed. Thick-walled steel pipes, as a kind of mechanically processed steel pipes, have many classifications. Customers should make it clear whether they need hot-rolled seamless steel pipes or seam thick-walled steel pipes, and some cast steel thick-walled steel pipes and hot-forged thick steel pipes. The form, the description that can be substituted, the direct emphasis that cannot be substituted.


How to determine the thick wall steel pipe:

1. Pay attention to its thickness, the pipe diameter is greater than 0.02 because only this kind of pressure can withstand large, even if it is pulled by force, it will not break. Secondly, it depends on whether its surface is smooth. Inferior thick-walled steel pipes often have scars on the surface, and some have small cracks, and their surface lacks luster. When you see such steel pipes, you must know that it is not a superior Steel pipe.


2. You have to measure the pipe diameter from different places. See if different places are the same, the steel pipe should be approximately the same everywhere, otherwise, it is inferior. When you choose, you should choose large manufacturers, which generally have strict packaging, and the packaging is relatively loose and often irregular.
