uPVC pipes Blue Casing

Special Locking System

uPVC pipes are manufactured with special jointing system. For this, grove is made at the end of pipe to fit the pipe in to another solid pipe easily. Then plastic rod, which is made with PVC and special chemicals will be inserted. This jointing system is very easy for installation up to 1000 feets and also installable in a very less time. Features and Advantages of pipes
  • Are used for bore / tube wells.
  • Are easy for handing, cheaper and flexible
  • Are light weight, rust free and easy for transportation
  • No special equipments are needed for installation. These pipes have an excellent record of performance in operational bore / tube well systems.
  • Installation is easy due to special locking system
  • The pipe is a very competitive product with chemical, non corrosive abrasion and biological resistance

 A unique product made from a special uPVC compound. Both the screen and casing pipes are available in diameter up to 250mm and can be used upto the depths of 1200 feets. well casing and well screen pipes are manufactured from uPVC compound developed under strict supervision of technical expert to meet tough environmental conditions of Coastal areas. The pipes are resistant to mineral salts and ground chemical ensuring a longer working life. In coastal area, pipes should be inserted up to tattle depth in loose soils. Standards well casing that has a compression resistance of 6.5 to 7.3 kg/ Cm 2 will be used to depths up to 450 feet. Gold casign pipes are manufactured under the specification of IS: 12818 - 1992 / CML 6547076 gold casing pipes can be used with submersible pump and vertical shaft type pumps providing suitable clearance. Two wall thickness are offered in the gold range. Owing to the increasing depths of wells it was found necessary to manufacture a heavy - duty range pipe for use at depths of 1200 feet. The pipe range has thicker wall section and high compression resistance. The plant is equipped with german twin - screw extruders capable of producing ribbed and casing from 40 - 250mm ND. Stringent Quality control tests are regularly conducted to ensure top quality products for use in borewells.

Resistance to Compressive Forces

Well Casing and screen pipe is subjected to considerable compressive force especially when the pipe being installed in the bore hole. The amount of force cannot be accurately predicted for any particular bore hole and will vary with the depth diameter, sub-soil, and type and method of gravel packing. Subsequent operation of the well shows that these forces stabilizer at a lower figure than at installation and start-up.

Thread Joints -Tensile Strength
  • Types of thread used in uPVC Tubes casing and screen pipe. Fine thread-whitworth pipe thread cut to Din 2999 with a pitch of 0.24 inch (6mm) giving 4 threads per inch.
  • GP Acme or Trapezoidal thread - cut to din 103 or BS 1104 with a modified depth to din 4925 pitch 0.5 inch (11mm)
  • Trapezoidal with rounded shoulder - cut to din 103 or BS 1104 with a modified depth to complement pitch. Pitch 0.6 inch (15mm)
  • Round thread - A special thread for use on heavy duty large diameter casing with a 14mm pitch
Ribbed Screen

To increase the permeability rates of well screens, a range of ribbed screens is offered. The longitudinal ribs hold off the packing sand and gravel and allow water easier access to the cut slots. The strength, chemical and physical characteristics of the ribbed screen are the same as that of the smooth surface.

Gold uPVC - Column Pipes - Submersible pipes

'uPVC Gold' uPVC Column pipes are manufactured with German Twin Screw Extruders using latest manufacturing and well equipped testing facilities under strict Quality Control management.

These Gold uPVC Column pipes are manufactured in white colour and sizes available from 1" to 4" in two varieties viz., Standard Duty and Heavy Duty. This product is manufactured by a special compound using a mix of few imported raw materials. Standards Duty pipes can be used for depth up to 500 feet and Heavy duty pipes for depth up to 1000 feet. Coupler's rib dimensions are also more due to more gripping purpose i.e, for 1", 1 ¼ & 1 ½" of rib's width is 6 mm and height is a 3mm and for 2", 2 ½, 3" & 4" of width is 8mm & height is 4mm. Gold uPVC Column pipes are 3 meters in length, each pipe having one coupler. Coupler is affixed at one end in the factory itself and other side is plain end for attaching the coupler from pipe to pipe. 'O' Ring & Gaskets are used for it, to provide leak proof joints, to observe the vibrations of the pump and for tightening purpose.

Gold uPVC Column Pipe - Features
  • Non – Corrosive: Compared to GI Pipes 'Gold' uPVC Column Pipes are rust proof and prevent rust formation.
  • Light in Weight: Gold uPVC Column Pipes are light in weight compared to GI Pipes. As such installation is easy and maintenance cost is also cheap.
  • Non – Toxic: It does not change colour, Odour & Taste of the water
  • Hygienic: It does not support any bacterial growth
  • Cost Effective: Gold uPVC Column pipes are cheaper compared to the price of expensive GI Pipes
  • High Tensile Strength: These pipes are having high Tenstile Strength of 55 + 5 Mpa
  • High Impact Strength
  • High Vicat Softening Temperature
  • Low Power Consumption: As these pipes have smooth internal surface, less energy is required to pump the water, as compared to the energy required for pumping water under conventional system.
  • More grip for coupler tightening due to high rib dimensions.
  • '0' Ring & Gasket: '0' Ring provides leak proof joints and Gaskets observe the vibrations of pump at the threaded joints.
Applications

Gold uPVC Column pipes are used in bore wells for Domestic, Industrial, Agricultural & Lift irrigation purposes.

Submersible Pump Installation

Do's and Don'ts
  • Before installing the submersible pump in borewell hook which is attached to the Chain block, should not hang to the clamp
  • At the time od installation of submersible pump in borewell, hook should be hanged with the iron ropes on both sides of clamp. It leads to equal weight on submersible pump. Before taking out the submersible pump in well, it should be one
  • If motor fails in borewell, iron rope should be hanged both sides clamp with the help of chain block for taking out the pipe and motor. Then there will be no breakage of pipe.
  • Submersible pump cables can be locked with pipe using (stuli) plastic wire (Not with GI wire)
