Product Description
Description : cold drawn steel pipes, cold drawn tubes are precision tubes with exact tolerance on OD and ID. When hot finished tubes can not meet requirement on OD and ID tolerance, we will cold drawn the hot rolled tubes to get better tolerance. They are also called ready to hone or ready to skive tubes.
