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.Keywords:cds tubing,cold drawn pipe,drawn tubing,drawn pipe,cold drawn seamless tubing,cold drawn steel tube,cold drawn tube,cds steel tubingcds tube suppliers,cold drawn seamless steel tube,drawn tubing pipe,cold drawn steel pipe,drawn steel tube,cold drawn steel pipe,cold drawn seamless tubes,cold drawn tubes, hydraulic cylinder ready to hone tube
