摘要： The present application is for an apparatus (20) and a method for bending pipes (22) of large diameter. The apparatus includes two major portions, a bending mechanism and a hydraulic system to power the bending mechanism. The bending mechanism includes three components: a bending die (28), a stiffback (30), and at least one outboard bending cylinder (42). The bending die is rigidly attached to a frame (24) of the apparatus, while the stiffback is flexibly attached to the frame and moves via operation of the bending cylinder. Operation of the bending cylinder moves the stiffback toward the bending die to clamp or bend the pipe. The hydraulic fluid supply system (80) includes two components: a hydraulic pump (84) and at least one pressure-sensitive regenerative valve assembly (96). The apparatus allows rapid clamping of the pipe section at reduced pressure via hydraulic fluid regeneration, while providing full hydraulic force for pipe section bending.

摘要： An improved internal line up clamp (10) is disclosed which has an integral back up ring (12). A first set of pipe clamps (22) move radially outward to engage the inner surface of a first pipe (14). A second set of pipe clamps (62) and a set of back up ring segments (202) are simultaneously moved radially outward into engagement with the inner surface of the pipes. The back up ring segments (202) are spring loaded to exert a relatively constant back up force against the inner surface of the pipes at the weld. In a modification, a fill block (118) can be used to fill the gap between adjacent back up ring segments when engaging the inner surface of the pipe. The back up ring segments support the shoe elements (220). The shoe elements are spring loaded to accommodate diameter mismatch and non-circularity of the pipe ends. The back up ring segments rotate about a radial axis from the pipe centerline. Tapered ends on the back up ring segments provide for the decrease in ring circumference necessary to lower the ring segments.

摘要： A method for girth welding of metallic pipes consists in beveling one pipe end in order that, when it is aligned with an identically beveled pipe end on another pipe, results in a bevel of a “cruet” design with a rounded bottom part larger than an upper part with parallel walls. The diameter of the welding wire used for the welding method is within 1.2 and 1.4 mm and the wire contains low levels of impurity including sulfur and phosphorus. The welding technique used is a “strip” technique which does not provide employ weaving or oscillation of the welding torch.

摘要： A line-up clamp unit (20) is powered by a diesel engine (22) which drives a hydraulic pump (80) for operating hydraulic equipment in the unit. The unit includes a line-up clamp (48) which has front shoes (52), rear shoes (50) and expanding copper back-up tiles (54). Drive wheels (38) are deployed by a hydraulic cylinder and operated by a hydraulic drive motor. Brakes are also operated hydraulically. A group (68) of aligning assemblies are electrically operated and function to extend L-shaped members (68a,74a) to beyond the diameter of the pipe (210) being welded so that the unit (20) can be retracted and automatically positioned at the end of a pipe section (210). A control box (76) is mounted to the line-up unit (20) and includes a radio receiver for receiving control signals and producing corresponding electric control commands for operating the hydraulic and electric components of the line-up unit. A remote control radio transmitter (122) has operating mechanisms, including push buttons and toggle switches, for operating the multiple operative elements of the line-up unit, including the engine, drive motor, brakes, line-up clamp and aligners.
