Pvc Pipes We are reckoned as one of the reliable distributors in India who also sourcve these from the reliable manufacturers. The raw materials used for these PVC Pipes are sourced from reliable vendors ensuring high durability, tensile strength and resistivity to adverse conditions. These PVC Pipes are dimensionally accurate and are sturdy in nature. Specifications Maximum ambient temperature : 70` C Maximum installation depth - CM series : 250m CS series : 80m Installation : Vertical, Horizontal or Inclined Application Bore-well Casing, Irrigation, Domestic, Industrial mining, Chemical Distribution A better alternative to MS, ERW, GI, Asbestos, Cement and SS Pipes uPVC is almost inert to corrosion and chemical reaction. Hence, it can be used in salty, sandy and chemically aggressive water, without creating problems letter on. Installation Since uPVC pipes are lighter, they are easy to handle, transport and install Atypical installation is shown alongside. For detailed instruction, refer our installation manual Design Specification followed : IS 12818:1995 Surface finish of this pipe is extremely smooth, ehich reduces hydraulic friction Internal and external threading and bell-spigot ends ensure easy and reliable joining ribbed screen pipes are used especially when the outer surface area of abore-well casing pipe is to be increased. the ribs provide around 25% additional surface area by virtue of their design. Besides that, it holds gravel balls away from the pipe, at a distance of about 2mm. This arrangement cleans slits naturally due to vertical flow passage. and allows more water to seep in, resulting in higher yield than other plain screen pipes with the same bore. Top Material A combination to formulate perfect uPVC is achieved with the right selection of resins, heat stabilizers, lubricants, processing aids, impact modifiers and essential additives. With all ingredients and process parameters taken in the correct proportion. Types Aroma casing pipes are made as per IS: 12818 and DIN 4925 and are classified as: Plain Pipes These can be used as extension pipes to screen pipe. They are of two types: C. S. Pipe: For shallow-depth (up to 80 m) red colour code C. M. Pipe: For medium-depth (up to 250 m) yellow colour code Screen Pipes These pipes may be plain or ribbed. They have transverse slots and are mainly used in bore wells, from the water-table Level onwards. Ribbed Screen Pipes These pipes have longitudinal ribs and transverse slots. The ribs keep granulated soil away from the slots, and increase the permeability rating to more than double when compared to plain screen pipes. Top Properties Found to be excellent for shallow and deep bore wells, as: They have greater strength to weight ratio They have good di - electrical properties They can withstand rating temperatures ranging from 50 'C to 70 'C They are easy to install, due to superior threaded joints Properties Unit Value Specific Gravity G/cm3 1.40 - 1.45 Tensile Strength N/mm2 > 45 Impact strength cm.kp/cm2 > 5 Vicat softening temp `C > 76 - 83 Opacity % < 0.2 Reversion test at 150'C % < 2 Chemical Properties Aroma uPVC casing pipes are designed and manufactured to resist collapse pressure. An assembly is most vulnerable, to loads to which it is subjected, during and after installation. Once the system is properly confined by travel packing, its resistance to collapse increases Largely, and it is no longer a matter of concern. The collapse pressure mainly depends on the following :Diameter to wall thickets ratioExtent of residual stress, if any Physical properties of the materials and degree of ovality and eccentricity in the pipe Top Chemical Properties They have excellent resistance to salt, acid, alkali, oil, fat etc.They are capable of handling water and pH values ranging from 2 to 12They are also resistant to all kinds of acids used in we[L-generationThey are resistant to all types of weather-effectsThey are resistant to corrosion, erosion and encrustationThey possess higher resistance to chemicals Top Benifites Immune to galvanic or electrolytic erosion. No Surface corrosion. No protective coating required. Not affected by acids, alkalis, oils Et fats. Better fire resistance due to self -extinguishing nature of uPVC. Very smooth inside and outside surfaces, so lower frictionat losses. Does not support bacterial growth. No encrustation. Trapezoidal threads make joints easy to handle and install. No skilled labor required. Continuous ribs on screen with horizontal slots, allow over double the entry. Light-weight ; hence easy to handle and transport. Safe for potable water transportation. Most economical in installation. Reduces power consumption in the long run. Maintenance-free. No painting required. ^ Over half the solts get clogged bythe gravel pack. The V-Channel formed by ribs, Keeps the gravel pack 2mm away from slots. v Purpose of Casing Pipes: To furnish a permanent borehole of precisely known diameter.To prevent caving in of the bore-well into the already drilled hole.To prevent fitting of well by sand particles or formation fragments.To facilitate gravel-packing Et Clay packing for water filtration.

(for slot width of 0.2 mm - 3.0 mm) Permeability per m of screen K (m3/h) at VT=3 cm/sec. Slotting Standard slot width range Top Belling Each pipe is given a bell shape to facilitate the jointing using belting machine. Jointing Aroma plain, Screen & ribbed-screen pipes are provided with threading on the socket and spigot. The threads so made on the pips, have good tensile strength. And making smaller joints, enables them to withstand more suspended weight that arises as we go deeper. The load on the threaded joints gets reduced when they are submerged in water.
