Specifications
| 1.0 General 1.1 Carlon duct is manufactured to the following various industry standards and specifications for dimensional requirements. ASTM D 3035 Polyethylene (PE) Plastic Pipe (SDR) Based on Controlled Outside Diameter. ASTM D 2239 Polyethylene (PE) Plastic Pipe (SIDR) Based on Controlled Inside Diameter. ASTM F 2160 Solid wall High Density Polyethylene (HDPE) Conduit based on Controlled Outside Diameter (O.D.) NEMA TC-7 Smooth Wall Coilable Polyethylene Electrical Plastic Conduit. |
2.0 Material Carlon duct is manufactured from a suitable thermoplastic polymer conforming to the minimum standard of PE334420E/C as defined in ASTM D3350. (see table 1) Carlon High Density Polyethylene duct is manufactured in the following configurations: Smoothwall Smooth Interior and Smooth Exterior wall. Rib/Smooth Ribbed Interior and Smooth Exterior wall. |
3.0 Product Description Polyethylene duct and innerduct is an extruded coilable tubing for use as a single or multiple raceway. The conduit may be direct buried, encased in concrete and used as innerducts. Innerducts are used primarily to provide multiple raceways within an existing conduit system. |
