Basic Information
Scope
Scope: This document specifies the definition, symbols, and abbreviations of MUHDPE-PANS wrapped structural wall A-type pipes; materials, pipe structure and connection methods; technical requirements; test methods; inspection rules; marking; transportation; and storage. This document applies to nano-modified high-density polyethylene (HDPE) pipes produced by adding appropriate amounts of inorganic nanoparticles, light stabilizers, lubricants, colorants, etc. to HDPE resin, followed by high-temperature blending modification and unique molding processes. These pipes are suitable for underground use and are called nano-modified high-density polyethylene PANS assembled connection (MUHDPE-PANS) wrapped structural wall pipes (A-type) (hereinafter referred to as "MUHDPE-PANS wrapped structural wall A-type pipes"). The product is suitable for long-term working temperatures below 45℃ in underground drainage and sewage projects, and is mainly used in municipal engineering, transportation facilities, agriculture, and water conservancy construction fields. Main technical contents: Definition, symbols, and abbreviations of MUHDPE-PANS wrapped structural wall A-type pipes; materials, pipe structure and connection methods; technical requirements; test methods; inspection rules; marking; transportation; and storage.
