Abstract

PURPOSE: To make inner space of hollow component bright while keeping durability against UV and to improve passableness by providing an inner layer reflecting light in the hollow component. CONSTITUTION: A sewer 1 made of passable hollow component, namely of black plastic, has an inner layer 2 that reflects light, so that interior of the tube becomes bright while keeping UV durability. As for the inner layer reflecting light, bright or bright-yellow plastic layer 2 is extruded on the way of tube winding bend method along with flat or specially shaped tape. Accordingly, interior of black hollow component, particularly of tube or sewer, can be made bright to a considerable extent. Owing to this, passableness of hollow component for inspection and maintenance is considerably improved, and UV durability of black hollow tube is preserved.
