Precision seamless steel tubes are cold drawn high dimensional accuracy for construction machinery, hydraulic equipment and good surface finish precision cold drawn seamless tube. Precision seamless tube manufacturing mechanical structure or hydraulic equipment, can greatly reduce the machining time, improve material utilization, and help to improve the product quality. <br>   Cold drawn (rolled) pipe is divided into two kinds of circular pipe and shaped tubes: tube drawing typically requiring multiple drawing, drawing between each have a corresponding stress-relief annealing, cold drawn ensuring a smooth get on. From the appearance of cold-rolled seamless steel tubes tend to be small in diameter, hot-rolled seamless steel tubes tend to be large diameter. Rolled seamless steel pipe is higher than the hot-rolled seamless precision, higher price than hot-rolled seamless. Cold drawn seamless pipe diameter is generally smaller, mostly in 127mm or less.

Cold-drawn precision seamless steel pipe is used in mechanical structures, hydraulic equipment with high dimensional accuracy and good surface finish precision precision precision precision precision precision precision precision precision precision precision precision precision precision precision precision precision precision precision precision precision precision precision precision precision precision precision precision precision The selection of precision seamless pipe manufacturing machinery structure or hydraulic equipment, etc., can greatly save mechanical processing hours, improve material utilization, and help improve product quality.<br>   Cold pull (rolled) tube is divided into two kinds of round tube and shaped tube: cold pull steel pipe generally needs to pull more than once, between each pull to have the corresponding de-stress annealing, to ensure the next cold pull smoothly. From the outside, cold-rolled seamless steel pipes tend to be small diameters, hot-rolled seamless steel pipes are often large diameters. The precision of cold-rolled seamless steel pipe is higher than that of hot-rolled seamless steel pipe, and the price is also higher than that of hot-rolled seamless steel pipe. Cold pull seamless tube generally has a smaller diameter, mostly below 127mm.

Cold drawn precision seamless steel tube is a kind of precision cold drawn seamless steel tube with high dimensional accuracy and good surface finish for mechanical structure and hydraulic equipment. Choosing precise seamless tube to manufacture mechanical structure or hydraulic equipment can greatly save machining time, improve material utilization rate and improve product quality.<br>Cold drawn (rolled) pipe can be divided into two types: round pipe and special-shaped pipe: cold drawn steel pipe generally needs to be drawn many times, and there should be corresponding stress relief annealing between each drawing to ensure the next smooth cold drawing. The cold-rolled seamless steel tube is usually small diameter from the appearance, and the hot-rolled seamless steel tube is usually large diameter. The precision of cold rolled seamless steel tube is higher than that of hot rolled seamless steel tube, and the price is also higher than that of hot rolled seamless steel tube. The diameter of cold drawn seamless pipe is generally smaller, mostly under 127mm<br>
