Ring Stiffness Ring stiffness of a pipe can be defined as its ability to resist radial forces acting on it and the pipes resistance to ring deflection and structural damage. Buried pipes such as sewer and water pipes are subjected to soil pressure, hydrostatic pressure and live loads from traffic. SN4 is a pipe class for light and medium traffic load, SN8, SN12 is a pipe class for heavy traffic load according to EN ISO 9969, Thermoplastics pipes - Determination of ring stiffness. Strength and stiffness are two physical properties of materials. Both terms describe how strong the material is, but have different definitions. Strength is the capacity of an object or substance to withstand great force or pressure. Stiffness is the rigidity of an object (the extent to which it resists deformation in response to an applied force). Therefore, there is a difference between strength and stiffness, though they are used interchangeably. The main difference between strength and stiffness is that strength is the ability of an object to withstand stress without breaking whereas stiffness is the ability of an object to resist deformation when stress is applied. According to the EN 13476-3 standard the sewerage pipes resistance to external load-ring stiffness (SN) is of great importance. The pipe resistance is a feature characteristic for elastic pipes and represents a relation between geometric data and material characteristics. 06 Technically, the pipe’s ring stiffness is defined as: SN = EI / Dm³ Where: E – module of elasticity, in Pa Dm – mean pipe diameter, in m I – moment of inertia, in m4/m Standard pipe classes according to ISO9969 have ring stiffness of SN 4,8 and 12 KN/m2.

Unique Features of DWC Pipes Anti - Corrosion Perfect Hydraulic Properties UV-Resistance Resistant to Microorganisms Rodents and termites Excellent Chemical, Corrosion and Abrasion Resistance Properties Being in plastics, these pipes are free from corrosion and offer excellent resistance to wide range of chemicals. These pipes have excellent abrasion resistance which gives an edge over metal and concrete pipes. For buried pipelines the biogenous Hydrogen sulfide [ H2S ]corrosion plays a key role regarding the longevity of the system. The biogenous sulphuric acid corrosion only takes place above the water level and therefore only occurs in partly filled pipes. Thanks to the used material DWC systems guarantee optimum security and resistance. the Smooth inner surface having man coefficient 0.009 - 0.010 (which remain constant without any deterioration during life expectancy) helps in rapid disposal of flowing waste. Such a smooth surface greatly reduces the possibility of blockages and maximizes the flow characteristics and therefore carrying capacity increases by 40% over concrete pipes. Black polyethylene pipes are permanently resistant to atmospheric corrosion and UV radiation. Thus the pipes can be used and stored outside without the pipe material being damaged and no aging effect will occur. The smooth round surface of plastic pipes does not give the teeth of rodents sufficient hold to cause damage. Moreover even in termite-affected countries no damage to polyethylene pipelines by termites has ever been occurred. Polyethylene and polypropylene are not a nutrient medium for bacteria, fungi and spores, so that the material is resistant to all forms of microbial attack as well as to both sulphurous acid and sulfates. 08 Deflection & Flexure the Deflection of flexible pipes is controlled by the settlement of the soil. After settlement, traffic and other loads do not affect pipe deflection. When pipes are relatively more rigid than the soil, the traffic and other loads have to be resisted by the pipe. Many years of practical experience have shown that flexible pipes (b) can resist traffic and other load more effective than flexural resistant pipes (a) made of concrete or other rigid material. As shown in the drawing, the flexible pipes elude a selective strain by deflection. this means the surrounding soil absorbs this strain. Eco-Friendly Processing and reprocessing of these pipes does not have any adverse impact on the environment, watertight joints eliminates the possibility of soil and underground water pollution.

Excellent Stiffness Watertight Joints Material Characteristic Values Maintenance Free Cost-Effective Easy and Quick Installation Suitable to withstand heavy overload pressure (soil and traffic loads) and sustain various loads that they encounter during installation and in use. Joints are 100% watertight and hence free from any infiltration, ex-filtration and root penetration. Due to this feature, surroundings remain unaffected and the possibility of soil or underground water pollution is eliminated. Being free from scaling, encrustation and chemical re-activeness there is no need for any regular maintenance. Occasional flushing with water keeps the surface smooth and helps in enhancing the functionality Cost effective - 60 to 70% weight saving in comparison to solid wall plastic pipes and 95% lighter than concrete pipes makes these pipes much cost effective Due to longer lengths and lighter weight pipes, installation becomes very convenient and fast. These pipes are very easy to joint using slip-on techniques (Pipes are supplied either with integrally welded couplers or separate couplers). Unlike conventional concrete or metallic pipes, these pipes do not require any heavy handling equipment for installation due to their lightweight property. These pipes can be easily laid in constrained areas thereby saving additional extraneous costs. 09 Profile About System Perforation Quality Installation Long Life Being free from corrosion, chemical reactiveness and excellent abrasion resistance these pipes can last over a century.

23 Installation Transportation, Handling, & Storage Delivery Way There are a wide variety of pipe materials used in buried applications for the conveyance or storage of effluent. Most pipes may be divided into two basic classes: rigid or flexible. While rigid and flexible pipe may behave differently under installed conditions, the quality and method of installation are equally important for the successful long-term performance of either type of buried structure. When considering any pipe material, the resultant strength of the system is dependent on the pipe itself and the soil envelope as the two components interact to form the pipe/ soil structure and collectively support the loads Thermoplastic pipes such as High-Density Polyethylene (HDPE) and Polypropylene (HP) exhibit properties which make it ideal for use in buried applications. Thermoplastic pipe is lightweight making it easy to handle and manipulate by hand or with light duty equipment. It is also very durable and generally resistant to impact, UV degradation, and most chemicals. However, as with any pipe product, there are some basic precautions that must be taken to reduce the likelihood of damage and to ensure trouble free performance. This document addresses measures to help ensure the pipe is not damaged before, during and after installation Either in loose form or palletized depending on the type and quantity of pipe. Non palletized pipe can be unloaded by carefully rolling the pipe onto the forks of a front-end loader, and then onto the ground. Alternatively, the pipe can also be removed with the use of a sling or cable. the Pipe that is equipped with bell ends should be stacked in alternating directions to reduce the possibility of bell deformation RSP DWC System Profile About System Perforation Quality Installation

RSP DWC System 26 The high-density polyethylene (HDPE) corrugated pipe is a type of flexible pipe that has played a significant role in municipal engineering. The earth’s pressure of buried flexible pipes is shared between the pipe and soil. Since the stiffness of the pipes is smaller than that of the surrounding soil, when a load is applied to the soil surface, the relative downward deflection of the adjacent soil prism is less than that of the central soil prism, the central soil prism is subjected to an upward friction force (Figure 1), and the earth pressure acting on the pipe is less than the weight of the central soil prism [1] During the installation of a pipe, its deformation is affected by the compaction method [9], compaction equipment [10], groove width, backfill material, the thickness of the backfill pipe cover, pipe diameter, and pipe hoop stiffness [11]. Therefore, the structural behavior of a buried flexible pipe is influenced by the hoop stiffness of the pipe and the stiffness of the backfill [2]. The stiffness of the backfill depends mainly on the degree of compaction [3], water content [4], soil properties [5], and grade [6]. Therefore, the influence of the earth pressure above a flexible pipe on pipe deformation cannot be ignored, and the load acting on pipes can be divided into soil loads and external loads. At the same time, under different soil conditions, the force transmitted from the external load to the crown of the pipe is different [7,8]. Well compacted Moderately compacted No Compaction The level of pipe deflection depends on the quality of trench backfilling DWC-Soil Stiffness Figure 1
