Product Description

Nirmaan Casing pipes are widely used for bore-wells, irrigation, chemical distribution etc and can be installed n vertical, horizontal or inclined positions.

Nirmaan Casing Pipes are manufactured according IS *********0 standards and are available in the following 3 types :

(i) Plain Casing Pipes : These are generally used as extension pipes to screen pipe They are of two types C. S. Pipe For shallow-depth (up to *0 m) red colour code. C. M Pipe For medium -depth (up to **0 m) yellow colour code.

(ii) 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.

(iii) 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.

• Casing pipes are primarily used for Bore-well Casing, Irrigation. Domestic wells, Industrial mining. Chemical Distribution etc.
• UPVC casing pipes provide a significantly cheaper, longer lasting and maintenance free alternative to MS. ERW, GI, Asbestos, and SS Pipes uses for similar applications.
• UPVC casing pipes provide a significantly cheaper, longer lasting and maintenance free alternative to MS. ERW, GI, Asbestos, and SS Pipes uses for similar applications.

• These pipes are manufactured with very good quality internal and external trapezoidal threads and bell-spigot ends, which ensure easy and reliable joining.
• Ribbed screen pipes are generally used to increase the outer surface area of a bore-well casing pipe. The ribs provide around *5% additional surface area by holding the 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 that results in higher yield of water than other plain screen pipes with the same bore.
• These pipes are made with extremely smooth internal surface that produces minimal hydraulic friction facilitates easy transport of water.
