ULTRAVIOLET IRRADIATION DEVICE AND METHOD OF APPLYING ULTRAVIOLET CURING RESIN ONTO INSIDE OF PIPING

摘要

PURPOSE:To provide a UV irradiation device capable of performing irradiation of UV rays light so that exposed dose becomes uniform all over the surface of resin to be treatred at the time of UV treatment of UV curing resin applied onto the inside of piping. CONSTITUTION:This is a UV irradiation device where it is constituted of a UV irradiation body 10 formed into a long-sized form and guides 30, 40 which are formed into a state of concentric circles having an axial line 11d of the UV irradiation body 10 for its center and possesses elasticity and the axial line 11b of the UV irradiation body 10 and an axial line are caused to coincide with each other by the guides 30, 40 pressure-contacted with the inside of piping 50.
