Handbook Plastic Pipe Ringstiffness 5

Determination of the deformation of the segment The segment is deformed to an extent as it would be during a deformation of the whole pipe of 3%. The deformation of the segment is calculated according to the following equation: YRS = YS X α79O = 0.03 X di x 0.29 YRS = deformation of […]

Handbook Plastic Pipe Ring Stiffness part 3

Alternative Test Procedures for Ring Stiffness All Manufacturers of large diameter plastic pipes face the same challenge regarding regular testing of ring stiffness. Especially dimensions bigger than DN 2000 are problematic, because of typical existing infrastructure in laboratories. The weight of the cut pipe lenght and the size it self require special equipment to […]

2. Standard Ring Stiffness Test Procedures Mainly we differ two different procedures to measure and evaluate the pipe-stiffness: a. Testing under constant load acc. DIN 16961-2: Thermoplastic pipes with profiled wall and smooth pipe inside b.Testing under constant speed acc. DIN EN ISO 9969: Thermoplastic Pipes-determination of Ring stiffness At noth procedures a cut length […]

Handbook Plastic Pipe ring stiffness

Ring Stiffness Alternative Test Method for Thermoplastic Pipes General preface to importance of stiffness The measurement of Pipe-stiffness is described in different national and international standars. The Ring-Stiffness of Pipes is one of the important indicators for the evaluation of Pipe stability. But Ring-Stiffness should not be overvalued, always is has to be considered that […]

III. Characteristics of Materials mattering for sewage systems Concrete/Ferroconcrete has been used since ages past for sewage systems and thus profits from long experiences. Concrete is utterly solid, stable and resistant against shifting during installation. Later on, pipes may likely shift because of different pressures. Furthermore it is high temperature resistantand inflammable. On the other […]

Factors causing damage: Physical (frost, heat, UV, butt, pressure, earthquakes…) EXMP 1: When water is freezing during very low temperatures, it expands. When the pressure cannot release, the pipe containing the frozen water might burst. The trouble is to detect those flaws and cracks caused by frost in time. Wet walls in domestic pipes or […]

Hand Book on Large Plastic Pipe

Damage and vulnerability of materials in sewage systems This essay focuses on three central questions : What are the most common damages happening to pipes in waste water systems? By which factors are such damages caused? Which material is especially weak or strong in resistance against certain damages? The advantages of pipe-materials and the […]

Plastic pipe VS Concrete Pipe In Rainwater and Sewer Drainage

With the same pipe diameter and the same flow rate, the DWC pipe can be used to reduce the slope and reduce the buried depth. Under the same diameter and the same slope condition, the flow rate can be increased to improve the water passing capacity of the pipe.
