Title:
METHOD FOR PROTECTING METALLIC TUBE-CONNECTING PART FROM CORROSION
Document Type and Number:
Japanese Patent JP3779756
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for protecting the metallic tube-connecting part from corrosion, capable of forming a hard anticorrosive protective layer excellent in corrosion preventiveness on the weld zone of clad metallic tubes without using a die in a short time.
SOLUTION: A cylindrical body 4 consisting of thermoplastic resin is arranged to cover the connecting part A including the weld zone of metallic tubes 1 and 2 and the exposed surfaces 1a and 2a of the tubes on both sides of the weld zone. A liq. reactant contg. a norbornene-base monomer, a metathesis catalyst and an activator is injected into a cavity B formed by the connecting part A and the cylindrical body 4 and then cured to form an anticorrosive protective layer covering the connecting part A.
