What is a thermal expansion seamless tube

- Feb 16, 2019-

Thermal expansion seamless pipe is what we often say thermal expansion pipe, the density is relatively low but the contraction is very strong steel pipe, (seamless steel pipe) can be referred to as thermal expansion pipe.A finishing process in which the diameter of a pipe is enlarged by means of cross rolling or drawing.In a relatively short time to thicken the steel tube, can produce non-standard, special type of seamless pipe, and low cost, high production efficiency, is the current international rolling field development trend.

High quality carbon structural steel and alloy seamless steel tube for chemical equipment and pipelines with working pressure of 10~30Ma.(3) gb3087-82 seamless steel tubes for low and medium pressure boilers and gb5310-95 seamless steel tubes for high pressure boilers.15, the structure of stainless steel seamless steel tube (GB/ t14975-2002) is widely used in chemical industry, and has good organizational stability, the use of steel: quality carbon structural steel steel number has 20G, 20MnG, 25MnG.
