The designed yield of a tubewell is 150m²/h (1.5 Cusecs) and a screen having 20% open area is proposed to be used in a length of 20m to tap an acquifer of 25m thick. Diameter, of the screen is to be worked out.As Q = A x V

Where Q = discharge in m²/s, A = effective open area of the screen V = entrance velocity in m/s (to be ltd. to 0.03 m/s)

Therefore, A = 150/3600 x 1/0.03 = 1.39m² Taking effective area as 50% of that provided, in order to taking into account the reduction of the effective area of the screen opening with time due to incrustation rearrangement of the acquifer particles around the screen and coverage by gravel, etc.

The required open area = 2 x 1.39 = 2.78m² Open area of pipes = x d x l x open area Where d = dia of pipe, l = length of pipeTherfore, d = 2.78/ x 20 x 20 = 0.22m or 220mm

The required sceen dia works out 220mm.

Acquifer Material Classification - The acqifer material may be classified into various categories according to the following ranges of the particle size:

All dimensions are in millimetres

The values have been calculated on the basis of the formula:
W=0.024 66 x (D-t) t kg/metre. Where D = outside diameter in mm, and T= thickness in mm.

All dimensions are in millimetres

Product Specifications
Dimensions of Plumbing Pipes to ASTM D 1785 and Threaded to match G.I. Pipes as per IS : 1239 (Part-1) or IS:554

Specifications

• Maximum ambient temperature : 70° C
• Maximum installation depth - 80m to 250m
• 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.
• A typical 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.

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
Apollo casing pipes are made as per IS: 12818 and DIN 4925 and are classified as:

Properties

Physical Properties
Found to be excellent for shallow and deep bore wells, as:

1. They have greater strength to weight ratio.
2. They have good di - electrical properties.
3. They can withstand rating temperatures ranging from 50° C to 70° C.
4. They are easy to install, due to superior threaded joints.

Chemical Properties

1. They have excellent resistance to salt, acid, alkali, oil, fat etc.
2. They are capable of handling water and pH values ranging from 2 to 12.
3. They are also resistant to all kinds of acids used in well-generation.
4. They are resistant to all types of weather-effects.
5. They are resistant to corrosion, erosion and encrustation.
6. They possess higher resistance to chemicals.

Benefits

• Immune to galvanic or electrolytic erosion.
