Method of withdrawing elongate tubular members

摘要

An elongated tubular member is withdrawn from a bore in a support member by fixing at a leading end of the tubular member a hollow adapter, inserting through the tubular member and the hollow adapter a rod having an overall length greater than the combined length of the tubular member and the adapter, securing said rod to the adapter at one end of the tubular member, securing a broach to the rod at the other end, pulling the tubular member by suitable gripping means to withdraw it from the bore and thereby drawing the broach through the bore to re-shape it.
