摘要： PURPOSE: A multilayer resin pipe is provided to minimize a spider line generated in an extrusion process and to suppress deformation by an external force. CONSTITUTION: A multilayer resin pipe(10) comprises an inner layer(12), an intermediate layer(13), and an outer layer(11). The inner layer, the intermediate layer, and the outer layer are formed with resin compositions. Polyvinyl chloride resin comprising the inner layer and the outer layer has a K-Value of 65-68. Polyvinyl chloride resin comprising the intermediate layer has a K-Value of 65-70. A lubricant is mixed with one or more kinds which are selected among hydrocarbons, carboxyls, esters, and metal salts.
