PRODUCTION OF COLD-DRAWN PRECISION SEAMLESS STEEL TUBES FOR AUTOMOBILE PURPOSE

On the basis of a study concerning application requirements for motor-purpose cold-drawn precision seamless steel tubes and relevant technical criteria of the said product used in former USSR,the Ukrainian State Tubing institute set up the manufacturing process of the said cold-drawn precision tubes. Introduced in the paper are the characteristics of the process and some measures used to ensure the product geometric accuracy. With the said process,cold-drawn precision seamless steel tubes up to relevant application requirements have been produced.
