Abstract
A protective cover for an insulated pipe bend. A corrugated band-form material is spirally wound into a tube and the adjoining tube edges are secured, such as by lapping, to form a non-slipping joint. The corrugated tube thus provided can be readily shaped to conform to an existing tube bend. The corrugated tube is cut lengthwise into two or more parts which are then placed over the insulated pipe bend. The cut edges are re-joined to form the protective cover.
Claims13
A method of applying a protective covering around insulated pipe bends comprising the steps of:
- providing a protective tube made from a spirally wound, band-form material, each turn of the spirally wound, band-form material being secured to an adjacent turn by a self-binding lap and being corrugated by at least one corrugation wave running in the longitudinal direction of the band-form material forming said turn;
- cutting said protective tube along its length to form at least two parts;
- shaping said protective tube to conform to the shape of an insulated pipe bend;
- positioning said two parts of said protective tube around said insulated tube bend with the cut edges thereof in adjacency;
- and
- joining together said cut edges to form a protective covering around said insulated pipe bend.
