PROCESS OF MAKING ARMORED PIPES.
Specification of Letters Patent.
Patented July 22, 1913.
Application filed. August 15, 1912. Serial No. 715,198.
To all whom it may concern:
Be it known that I, IIEINRICII Kntienn, a subject of the King of Prussia, residing; at
.Halle-0n-the-Saale, in the Kingdom of Prusa conduit for acid and sea water and shall be capable of resisting high pressure from within.
My new pipe consists of an impervious metal tube and a tubular cover or jacket made of sheet metal provided with holes or perforations, or of wire braid. After the said tube, which is preferably made of soft metal, such as lead or other metal, capable of expansion, has been placed into the said jacket, the metal tube is expanded to such an extent, as to cause the jacket to become embedded in the metal of the tube. Owing to the expansion, the metal of the tube is forced into the interstices, perforations or meshes of the jacket wholly or partially filling the same. The expansion of the metal tube can be effected in any convenient manner, for example by means of a mandrel, or the like. The cover or jacket firmly incloslag the metal tube imparts to it a high degree of capacity to resist inside pressure.
lily invention is shown in the accompanying drawing, in which- Figure 1 is a side elevation, partly in sec tion, and Fig. 2 is a cross section of a portion of a pipe in accordance with my invention.
My pipe consists of the smooth-walled tube a made of lead or some other metal capable of expansion and of a tubular covering, or jacket I). This jacket may consist of wire braid, perforated metal (sheet metal), or the like. The smooth-walled metal tube a is inserted in the jacket or braid 7) after which both the jacket and the tube are firmly and immovably connected by the expansion of the soft metal tube from within. By this expansion, which can be effected by means of a mandrel, rolling member or the like, the metal of the soft metal tube a is forced into the interstices, perforations or meshes of the jacket or braid b, so as to wholly or partially fill them, whereby the jacket becomes embedded in the metal of the tube, as shown by the broken lines in the figures. Thus an intimate and firm connection between the tube a and jacket 7; is effected, whereby the tube is given great resistance to high pressure from within. Before expansion the metal of the tube a may be h ated to enable the outer layer of its wall to be more easily forced into the openings, perforations, meshes, depressions or protuberances 0f the jacket.
lVhat I claim is The process of making an armored pipe, consisting in placing a met tl tube, capable of being expanded from within, into a jacket having interstices, and then expanding the said tube, thereby causing said,
jacket to become embedded in the metal of said tube.
In testimony whereof I have afiixed my signature in presence of two witnesses.
