internal pressure. to which they are subjected in use, because they are liable to become weakened by corrosion. This liability could be minimized by coating the pipe internally or externally or both, as may be necessary, with a protective material such as cement, asphalt, concrete or pitch; but this is diflicult becauseof the feeble adhesion between any of these materials and an iron or steel surface. It is an object of my invention to improve this adhesion; the methods of doing so which have been applied to pipes of small diameter, such as condenser tubes, namelyby roughening the surface or applying a wire gauze wrapping before the'coating o-per-j ation, are inapplicable to large diameter water pipes.

My invention consists in rolling into pipe form a plate of steel or iron on one or both faces of which there has been produced a serrated or chequered pattern by rolling or pressing the plate in the course of manufacture by a patterned roller or press in known manner; this pipe form becomes a pipe when the edges of the plate are welded together in known manner.
My invention further consists in lining or coating or both lining and coating the finished pipe with a protective material of the kind hereinbefore named.
A diagonal 'or' chequered pattern on the plate is very useful; however, other designs 7 are also satisfactory, such as serrations or ridges in parallel or wavy lines, running either longitudinally or transversely in the pipe tobe formed.
Pipes protected from rusting by coverings of the kind in questioncan be made of lighter material than is safe for uncovered pipes subject to rusting; there ,is a limit to this diminution of weight, however, because the stilfness'of the pipe is impaired as the weight is diminished. The pattern provided accord.- ing to my invention lends sufficient stifiness to metal of a Weight which could not well be used if the metal had a plane surface.
Cylindrical corrugated sheet metal reinforcement in pipes made of concrete or bituthe patterned surface to minous material is well-known; my invent1on is in no way concerned with-pipes made of such reinforced material.
Having thus .fully described the nature of I 1. A water pipe, light in weight, consist-f ing of a plate of steel or iron having a well defined pattern impressed thereon and which is rolled into pipe form and welded and has a coating of. material applied to the patterned surface to protect the metal from rust.
