ADHESIVE METHOD FOR SPIRAL PIPE

摘要

In a spiral pipe adhesion method, when a spiral pipe used as a drainpipe or water conduit is bonded, adhesive resin having an I beam shape is improved to an H beam so that rigidity coefficient or annular rigidity coefficient is improved. Law material such as polyethylene is used to form a rectangular profile having empty or filled cavity. Resin is supplied by an auxiliary extruding apparatus to wrap the profile in an H beam shape to make the profiles adhere to each other. Thus, since the adhesive resin layer is formed in an H beam shape, the profile can bear the external pressure, impact and load and is not breakable and rigidity coefficient is drastically improved. Also, the life span of a product is economically extended and an aesthetic appearance can be obtained.
