5 INTRODUCTION Through a committed, quality focused and comprehensive research program and development, Shield has become a leader in manufacturing and supply of high quality HDPE piping systems. Shield HDPE pipes and fittings are manufactured as per ISO and AWWA Standards from its manufacturing facilities located in Dubai, U.A.E. Products must pass strict quality control procedures and are routinely checked throughout the production process, from the inspection of incoming raw materials, to the storage of the finished products to ensure they are fully compliant with the relevant standards. Continual improvements, innovative production techniques and review of existing facilities are always carried out without affecting the consistency of the production process at the factory. Shield High Density polyethylene pipes and fittings are extremely tough, durable and strong for long service, trouble free installation, flexibility and offer many other features. Therefore, Shield HDPE piping system is an effective solution for municipal, industrial, marine, agricultural and fire fighting applications. Its efficiency has been tested and proven for above ground, surface, buried, slip lined, floating and sub-surface marine applications. Shield HDPE is capable of meeting all your piping requirements. 1

6 CHARACTERISTICS OF HDPE We recommend Shield HDPE as your piping solution due to the following characteristics: Impact Resistant Elastic Thermal Resistant Smooth Internal Wall Wear Resistant Weather-resistant / Uv Resistant Poor Heat Conductivity Non-toxic Insulating Highly Suitable for Welding Homogeneous Welded Joints Prefabrication Light weight PHYSICAL PROPERTIES OF HDPE CHARACTERISTICS UNITS PE80 PE100 TEST STD DENSITY gm/cm EN ISO DESIGN STRESS MPa 5 / EN ISO1167 TENSILE STRENGTH AT YIELD N/mm EN ISO FLEXURAL MODULES (BEND CREEP) N/mm EN ISO ELONGATION AT BREAK % > 600 > 600 EN ISO1167 CRYSTALLITE MELT RANGE C DIN SURFACE RESISTANCE O 1013 > ASTM D 1639 COEFFICIENT OF LINEAR EXPANSION mm/m*k DIN HEAT CONDUCTIVITY AT 20 C W/m*K EN IMPACT STRENGTH AT 23 DEG C Kj /m EN ISO BRITTLENESS TEMPERATURE C < -70 < -70 ASTM D SHORE HARDNESS D DIN MELT FLOW RATE (MELT FLOW INDEX MFI) g/10min BS 3412 ISO 1133 WATER ABSORPTION % EN ISO 62 2

7 MRS-MINIMUM REQUIRED STRENGTH Polyethylene pipes and fittings materials are evaluated on the basis of their Minimum Required Strength. When PE100 pipes are hydrostatically tested at 20 deg C, ISO 1167 specify a Minimum Required Strength at 50 years of 10 Mpa (100bar) - MRS100. When PE80 pipes are hydrostatically tested at 20 deg C, ISO1167 specify a Minimum Required Strength at 50 years of 8 Mpa (80bar) - MRS80. The MRS value for PE100 compound is 10MPa. PE100 pipe has enhanced toughness, higher permissible design strength and improved resistance to rapid crack propagation in addition to benefits in efficiency and economy. This allows the design engineers to use PE100 pipes at substantially higher operating pressures than PE80 pipes with equivalent SDR rating i.e. allows PE100 pipes to be produced with thinner walls than PE80 pipes of equivalent SDR rating. DESIGN STRESS & SAFETY FACTOR Safety factors take into account handling conditions, service conditions and other circumstances not directly considered in the design. In terms of ISO 4427 the minimum safety factor is This factor, when applied to the Minimum Required Strength (MRS), for the particular material classification (e.g. PE80, PE100), gives the maximum allowable hydrostatic design stress for the designated material. Designation of material MRS at 50 years and 20 deg C (Mpa) Hydrostatic design Stress (Mpa) PE PE MRS,c=1.25 c PIPE SDR AND PRESSURE RELATIONSHIPS SDR is the standard dimensional ratio, it is the ratio between the OD (outside diameter) of the pipe & the wall thickness. Eg: As per ISO 4427, the SDR of 110mm 16 bar rated PE100 pipe is 110/10 = 11 ie. SDR11 As per ISO 4427, the SDR of 110mm 10 bar rated PE100 pipe is 110/6.6 = ie. SDR17 As per ISO 4427, the SDR of 110mm 20 bar rated PE100 pipe is 110/12.3 = 8.94 ie.

8 PRESSURE REDUCTION CO-EFFICIENT FOR PE100 & PE80 as per ISO4427: 2007 When a PE piping system is operated at a continious constant temperature higher than 20 deg C, a pressure reduction co-efficient as given in the below tables are applicable. From the above table Pressure rating of different SDR s at various level of temperature can be determined, therefore pipe selection can be made at the design stage.

12 SHIELD HDPE PIPING SYSTEM FOR WATER LINE PIPE SELECTION Design Engineers choose Shield PE100 piping system, as the system provides larger bore size because of its lower wall thickness. Moreover, at the same working pressure, designers can opt for lower SDR level pipe than in PE80 piping system.

13 GAS LINE SHIELD HDPE PIPING SYSTEM FOR GAS LINE Shield Polyethylene is the right choice for your Gas application due to its characteristics such as strength, flexibility, inertness, light weight and ease of maintenance and installation. Shield HDPE pipes are maintenance free with a design life of over 50 years under normal operating conditions. Shield manufactures HDPE pipes for GAS service as per ISO4437 standards which undergo rigorous quality checks throughout the entire production process to ensure their reliability and effectiveness for gas transportation. Shield manufactures gas pipes in a size range of 50mm to 250mm sizes from PE100 material grade. The preferred series of pipes are SDR11 and SDR17 for gas applications. Pipes are available in coils in order to reduce the number of joints to make a cost effective choice for contractors and clients. Pipes are also available in straight lengths of 6 or 12 meters. The jointing can be done by Butt-welding or Electro-fusion jointing methods, providing a completely homogeneous leak free system.

Dimension in millimeters Dimension in inches UNDERGROUND HDPE FIRE LINE CONNECTED TO ABOVE GROUND STEEL PIPE HYDRANT INSTALLATION Where local soil does not provide the needed support for the HDPE pipe, heavy thrust blocks or dense concrete mixes can sink. When a large thrust block sinks, it creates excessive bending moment and failure that we are trying to avoid. Where good local soil conditions exist, no thrust block or special bedding is required. Where local soil conditions do not provide needed soil conditions, the use of geotextile fabrics or stabilized soils offer another way to provide good proper support to pipe and fittings to prevent excessive bending. 10

15 DRAINAGE LINE SHIELD HDPE PIPING SYSTEM FOR DRAINAGE Shield also provides an effective and economic alternative to cast iron and other traditional systems. Shield HDPE drainage system is a total solution for all types of drainage requirements, soil and waste include above and below ground, and chemical waste applications. The exceptional performance is the result of versatile characteristics of Shield HDPE includes light weight, impact resistant and abrasion resistant make the system fit for long term alternative solutions to cast iron and other traditional systems.
