Abstract
A method of making a python in which a bundle of tubes is disposed coaxially within a close-fitting elongated sheath having a resiliently expandable inside diameter wherein the inside diameter is expandable by creating a pressure differential between the inside and the outside of the sheath to expand the sheath and inserting the tube bundle without substantial resistance from sliding contact with the expanded inside surface of the sheath, a pig being provided on the lead end of the bundle to assist passage through the sheath.
