METALLIC TUBE WORKING METHOD
Document Type and Number:
Japanese Patent JP3358431
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To easily bend a metallic tube into the desired shape without changing its sectional shape.
SOLUTION: A first hollow metallic tube 3, and a second metallic tube 5 arranged in the first metallic tube 3 are provided, the second metallic tube 5 is separated from an inner circumferential wall 3a of the first metallic tube 3, and an end part of the first metallic tube 3 is connected to the end part of the second metallic tube 5. The flowing material 7 containing the heating- hardening material charged space between the first metallic tube 3 and the second metallic tube 5, and after the metallic tubes 3, 5 are bent, the flowing material 7 is re-heated to the decomposing temperature of the heat-hardening material and decomposed and discharged.
