How much wall thickness can be called
thick-walled steel pipe? This is a bit doubtful. 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. Yes, but for a diameter of 219mm, 10mm is just a thin-walled steel pipe. The basic definition of thick-walled steel pipes lies in what customers call him. Points to note mean that when purchasing thick-walled steel pipes, customers should specify the material of their steel pipes and the single length of the steel pipes, because this involves the number of mechanically processed parts and some unnecessary waste.
Then there is the detailed size of the inner and outer diameters of the steel pipe, which must be included in the calculation because the processing amount of some parts must be reserved. As a kind of mechanically processed steel pipe, thick-walled steel pipes have many classifications. Customers need to know whether they need hot-rolled seamless steel pipes, seamed thick-walled steel pipes, and some cast steel thick-walled steel pipes and hot-forged thick-walled steel pipes. Form, replaceable description, irreplaceable direct emphasis.
