Title:
PRODUCTION OF RESIN-LINED STEEL PIPE JOINT
Document Type and Number:
Japanese Patent JPH06320620
Kind Code:
A
Abstract:

PURPOSE: To obtain a resin-lined steel pipe joint production method preventing the squeezee-out of a resin at the inner and outer peripheries of a flange part or radially into the pipe.

CONSTITUTION: In a resin-lined steel pipe joint production method in which an end part of a resin-lined steel pipe is connected to an object to be joined by an engaging flange formed at the end part and a flange engaged with the engaging flange, a resin layer 4 of the end of a resin-lined steel pipe 2 is previously chamfered before flanging. Thereafter, the other part than a part forming a flange 6 is pressed by a mold for arresting expansion. In this state, a molding rubber 13 is inserted into the resin-lined steel pipe 2. The molding rubber 13 is compressed in the axial direction of the resin-lined steel pipe 2 at the part forming the flange 6 to be deformed vertically to the axis of the resin-lined steel pipe 2. In this manner, the engaging flange 6 is formed at the end of the resin-lined steel pipe 2.
