System and method for forming a continuous strip/plate from a plurality of strips/plates and for forming a pipe from the continuous strip/plate

摘要: A system and method of forming a continuous strip from plurality strips, each having leading end trailing end. Embodiments can include apparatus that chamfers at least one the ends strip. The chamfered may then be positioned against successive ones strips. Once are another, first welding weld on side, above, other to form joints. two strips have been welded together, constitute An inverting invert inversion joints done so as not create reverse bend in second side opposite inverted junctions. pipe using strip, wherein successively welded-together continuously or semi-continuously supplied pipe.
