STEEL PIPE PRODUCTION EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2011/118681
Kind Code:
A1
Abstract:
Disclosed is steel pipe production equipment that has excellent steel pipe production efficiency and can carefully manage the traceability of the steel pipes. The steel pipe (P) production equipment (100) is equipped with a pipe production line (10), a heat treatment line (20) that is directly connected to the pipe production line, and a refinement line (30) that is directly connected to the heat treatment line, and is characterized in that at least a correction step for correcting bending in the steel pipe, an ultrasonic flaw detection step for detecting flaws in the steel pipe using ultrasonic waves, a surface inspection step for inspecting the surface of the pipe, a hydraulic test step for testing the hydraulic pressure in the steel pipe, an actual weight/length measurement step for measuring the weight and length of the steel pipe, and a marking step for marking the steel pipe with a stencil are executed in the refinement line (30), and in that the steel pipe is not conveyed off the line en route from the entrance of the pipe production line until the exit of refinement line.
