Abstract
PURPOSE: To obtain a non-defective metallic pipe lined with a synthetic resin without diffuculty, by expanding and curing an expandable adhesive applied to the inner surface of a large diameter metallic pipe into which a small scale synthetic resin pipe is inserted with separating bodies put between them.
CONSTITUTION: When the inner diameter of the metallic pipe 1 is 2R and the outer diameter of the resin pipe 2 is 2r, the height h of the non-rigid PVC separating bodies 3 tapered at the tip, having ridge sections, are 1W1.5 time as long as the clearance (R-r). The surface of the metallic pipe 1 is coated with the expandable adhesive 6 sprayed from the nozzle 4 inserted in the pipe 1 to form the adhesive layer 6, and the resin pipe 2 is introduced into the metallic pipe 1. Being made of a soft material, the separating bodies 3 are deformable suitably, fixed tightly by forced insertion, and the resin pipe 2 is fixed coaxially. The outer surface of the metallic pipe 1 is heated so that the adhesive 6 is expanded and cured.
