The thermal expansion of seamless steel tube
is the thermal expansion steel tube which we often talk about. Its density is relatively low, but the steel tube has strong contraction. (seamless steel tube) can be called the thermal expansion steel pipe. In a short time, the outer diameter of steel pipe can produce non standard, special type seamless steel pipe, and it has low cost and high production efficiency in a short time. It is a trend in the field of international pipe rolling.
Seamless steel tubes are also commonly referred to as automatic tube mills in the production of rolling mills. The round bar is cut into the required length, aligned at the end of the perforation end, then heated to the heating furnace and perforated in the punching machine. At the same time perforation and continuous rotation and movement, under the action of the reel and head, the capillary is gradually formed in the lumen. Then it is sent to the automatic rolling mill to continue rolling. Finally, the entire machine is the entire wall thickness, and it meets the specifications through the diameter of the sizing machine.
Seamless tube thermal expansion is seamless tube, because you buy a 530mm tube, no such model, the largest seems to be 460MM, the manufacturer only reheating once (reprocessing), the general should damage the quality of the tube, of course, see what you are doing. Of course, the price is more expensive, because the two processes are all passed.
