Abstract: A metal bend pipe having a bend portion bent in a semi-circular arc shape is provided, in which an identification part that enables one of the two end portions of the bend portion to be identified as the bending-start side or the bending-end side is provided, and the identification part is integrally formed as a protruding and/or recessed three-dimensional region. Thus, it is possible to easily and reliably identify which of the two end portions of the bend portion is the bending-start side or the bending-end side.

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: A production of tapered bent tube wherein a U-cup with a full opening is pressed to form from a brass plate by a primary mold. The two ends of the full opening of the U-cup are of different calibers. The U-cup is subjected to tempering treatment to eliminate its processing stress. An assembly forming mold is used to punch the fill opening of the U-cup to form a rough shape of tapered bent tube with two different calibers at two ends, and between the two ends with different calibers is a flattened part. The flattened part on the tapered bent tube is removed to form a tapered bent tube; then, the seam of the tapered bent tube is welded and smoothed by roller pressing process, to complete the two ends of different calibers. With aforementioned production method, since the primary mold adopts an expansion approach to form the outside portion of the tapered bent tube, the expansion ratios on the inside and outside of the tapered bent tube can be approximated to avoid cracks, so as to produce a tapered bent tube with a consistent thickness to enable better sound effect.

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: A hollow workpiece having a tubular end portion is deformed by first fitting the workpiece into a die formed with a cavity adapted to receive the workpiece with the end portion of the workpiece projecting along an axis out of the die and then engaging over the projecting end portion of the workpiece a feed sleeve in a pressure-tight fit. The sleeve and workpiece are supported relative to each other such that the holding portion can slide in the sleeve and that the sleeve exerts substantially no axial force on the workpiece. Then an interior of the workpiece is pressurized through the sleeve and to deform the workpiece outward against an inner surface of the die.

Abstract: A machine which forms pipe elbows and other curved conduits by spirally winding a thin strip of sheet metal. The machine includes spaced apart cutting rollers which are reciprocated toward and away from one another by cams in order to cut the strip into a series of interconnected gores having contoured edges. The contoured edges are progressively bent in a manner to interlock by sets of bending rollers that are reciprocated inwardly and outwardly by cams. The strip is spirally wound inside of a ring shaped winding shoe having dies which interlock the opposite edges of the strip. Crimping rollers act to firmly crimp together the interlocked edges to form an acme seam. Clutches permit the cams to be selectively stopped so that the conduit that is formed can be provided with both straight and curved portions.

Abstract: An apparatus for reducing the radius of the bend in a U-shaped tube comprises two squeeze dies and a back die. The back die is hollowed to form a chamber that accommodates the bent section of the tube and supports the entire circumference of the tube at the center of the bent section. Mating slide surfaces on the back die and the squeeze dies cooperate to extend the back die during squeezing in such a manner as to accommodate the longitudinal extension of the tube legs that results from the squeezing; i.e., there is no relative longitudinal movement between the squeeze dies and the tube legs. This arrangement enables relatively thin-walled tubes to be squeezed without undue deformation of the tube.
