<p>PURPOSE:To perform work in a short time by a simple means and moreover restrain the occurrence of the stripping of a coating material in propulsion work by covering a fiber reinforced synthetic resin pipe, divided plurality and formed into specific thickness and length respectively, on the outer periphery of heat contracting coating material covered on a corrosionproof coating layer to be stuck. CONSTITUTION:In right and left butt welded propulsion pipes and pipe end parts, the exposure parts 2a of a corrosionproof coating layer 2 shop-coated are overlapped to be covered by heat contracting coating material to be contracted and collosionproofly coated. Then the inner surface and end part of a halved fiber reinforced synthetic resin pipe 6 are stuck by adhesive 7. At that time, the total thickness of a joint part is made thinner than the that of the shop-coated corrosionproof coating layer 2 and a protective layer 3, and the fiber reinforced synthetic resin pipe 6, plurally devided and formed into L1 shorter than the end part interval L of the protective layer 3, is used to perform sticking.</p> |
