Abstract: A press fitting, including a tubular component and an end portion of the tubular component which can be compressed to make a connection. The end portion has an opening to receive a tube and a first region having an annular ridge to receive a sealing ring. A second region is arranged on the side of the ridge adjacent the opening and a third region is arranged on the side of the ridge remote from the opening. The overall wall thickness of the press fitting in the second region is increased at least in a section or sections in comparison with the wall thickness of the tubular component in the third region.

Abstract: The present invention relates to an upsetting press (1, 1′) for upsetting an end (2) of a metallic material pipe (3), e.g. for petroleum applications. The press (1, 1′) comprises a supporting structure (10) which defines a working space and first locking means (15) for locking the pipe (3) to be upset. The press further comprises first upsetting means comprising at least one first upsetting die formed by a first pair of half dies (21, 22) which can be separated and closed about the end (2) of the pipe (3) to be upset and at least one axially movable cylindrical punch (30). The press (1, 1′) further comprises die holding means which support the half dies (21, 22) moving them between a closing position and an opening position. According to the invention, the die holding means are independent from said supporting structure and are transversally movable (102) between an operating position in which the half dies (21, 22) can be closed about the end (2) of the pipe (3) to be upset and at least a non-operating position such that the half dies can be washed and/or lubricated outside the working space of the press.

Abstract: Preperforated tubing is produced by forming a perforation in flat strip of raw material, forming a hollow, cylindrical tube from the flat strip, and placing a removable plug into the perforation, so as to form a fluid-tight seal. A sealing element may be placed into the perforation. The perforation may comprise a hole, into which first and second countersinks may be formed. The sealing element may be placed into the first countersink, and the plug may be placed through the countersinks and the hole, such that the plug's body fills the hole and the plug's head fits within the second countersink.

Abstract: The present invention enables a manufacture of thickwalled fittings subjected to the effects of high temperatures, pressures and (or) aggressive media. Fittings manufactured according to the invention are designed for a high flow velocity. The formation of a curved fitting is effected by two pairs of dies, one thereof has flat working surfaces and the other, arcuate recesses. A tubular blank is successively reconstructed by said pairs of dies in the course of one or two strokes of a press.

Abstract: The disclosure pertains to a compression fitting for connecting conduit to outlet boxes and the like in which the body member is made by a series of press forming operations on a tubular blank to define a central upset portion having a hex configuration, and roll formed threaded end portions of different external diameters in which the diameter of the tubular blank is equivalent to the pitch diameter of the large end of the completed body member, and an indentation is rolled into the blank adjacent its smaller end to define the maximum throat size of the fitting and a stop for the conduit when received in the body member larger end. In making the body member, the blank is made from mild steel tubing fed through a cut off machine in which the indentation is rolled into the tubing and the blank is formed by severing same from the tubing to include the indentation located adjacent one end of same, the ends of the blank are deburred, the said one end of the blank is necked down to approximately the indentation, the blank is upset intermediate its ends to define the hex configuration, and then the threads are rolled into the blank ends, after which the body member is suitably coated. The reduced end of the body member receives a conventional box engaging lock nut while the larger body member end is equipped with a clamp nut and cooperating gland for fixing the conduit to the fitting. Also disclosed is a special die arrangement for necking down and upsetting the fitting body member.
