PVC-SRGL

Product catalog summary

Overview: The document provides technical specifications for ALNOR® ventilation systems, focusing on round plastic ventilation pipes. These pipes are manufactured according to DIN 8062 standards and are available in various materials and sizes.

Specifications: The pipes are available in materials such as PVC, PP, PPs, PE, and PVDF. The document specifies that pipes with a diameter larger than 500mm are made from sheets, while others are extruded. The outside diameter is the reference measurement for these pipes.

Materials and Designations: The document lists several material designations, including PVC-SRGL for polyvinyl chloride and PP-SRGL for polypropylene. Special order materials include PVCW-SRGL for white polyvinyl chloride and PPELs-SRGL for flame-resistant polypropylene with electrical conductivity.

Dimensions and Wall Thickness: A detailed table provides dimensions for various pipe diameters, wall thicknesses, and lengths. The table includes data for different materials, indicating variations in wall thickness and length based on the material used.

Standards and Ratios: The document explains the Standard Dimension Ratio (SDR), which describes the relationship between the pipe's outside diameter and wall thickness. A higher SDR indicates a thinner wall. SDR 127 is noted as a special series for ventilation pipelines.

Key Notes: The document emphasizes that the diameter listed is the outside diameter and highlights the availability of different wall thicknesses upon request.

Plastic circular ventilation pipes Description Round plastic ventilation pipes are joined by welding (or PVC gluing up to 0250). Manufactured in accordance with DIN 8062 standards for ventilation pipes. PVC pipes of larger diameter than 500mm are made of sheets. Pipes made of PP, PPs, PE and PPELs are extruded. Other wall thicknesses are available on request. Available materials - designation example PVC-SRGL-... - PVC polyvinyl chloride PP-SRGL-... - Polypropylene PPs-SRGL-... - PPs flame resistant polypropylene PE-SRGL-... - Polyethylene Available materials - upon special order PVCW-SRGL-... - Polyvinyl chloride white PPELs-SRGL-... - Polypropylene EL flame resistant and with electrical conductivity PVDF-SRGL-... - Polyvinylidene fluoride Designation example: Product Code: PVC - SRGL - aaa material type - SDR (Standard dimension ratio) describes the correlation between the pipe outside diameter and the pipe wall thickness. The higher SDR is, the smaller the wall thickness is. SDR 127 is a special series for ventilation pipelines. ALNOR ventilation systems is a legally protected trademark and technical patent.
