A pipe bending machine has a stiff-back which is driven by a pivioting wedge. A linkage applies force from the actuator to the wedge in a direction parallel to a longitudinal axis of the stiff-back. The stiff-back pivots on a first fulcrum and the wedge slides on a bed which pivots on a second fulcrum. The actuator drives the wedge between the stiff-back and the bed to rotate the stiff-back at the first fulcrum and bend the pipe seated in the stiff-back against the pipe bending face of a die. The conversion of the longitudinalforce applied to the wedge into a transverse force applied to the stiff-back provides a significant mechanical advantage which varies directionally as the stiff-back rotates about its fulcrum to maintain a constant force on the stiff-back.
B21D 7/022 - Bending rods, profiles, or tubes over a stationary forming memberBending rods, profiles, or tubes by use of a swinging forming member or abutment over a stationary forming member only
A pipe bending machine has a beam mounted in see-saw pivotal relation on a fulcrum and spaced apart cradles support the pipe. An actuator initially drives the second cradle and the beam apart to pivot the pipe about the first cradle until the pipe is in contact with the die and thereafter drives the beam away from the second cradle to bend the pipe against the die. The mechanical advantage of the levered operation requires only a single actuator motion to bend the pipe. An external mandrel allows the pipe to be incrementally fed through the bending machine and secures the pipe against cross-sectional distortion during the bending process.
Metallic objects such as steel pipes and shipbuilding plates are welded using complemental bevels in the faces to be welded which, when abutted, define a channel of cruet shaped cross-section. The cruet shaped channel allows the filling weld passes to be performed using a welding instrument oscillated only at tolerance amplitudes in a range of 1.5 mm +/- 0.5 mm rather than bevel width amplitudes. The process can be used in single or double side welding applications.
A method and system for storing, delivering and spooling pipelines, such as underwater pipelines used in off-shore well production systems, enables continuous pipeline reeling operations for multi-mile pipelines without the need for welding stops, a spool base of corresponding multi-mile length, a straight line path from storage to ship and/or stern mooring of the reel carrying vessel. Bending radii for the pipeline from welding to reeling are held to a determined minimum within the range of plastic deformation radii of the pipeline and preferably within the range of elastic bending radii of the pipeline.
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.
