"I-GRO" Grey Pipes made under this Indian Standard are used for discharging of soil waste and rain water from buildings. These pipes along-with molded fittings which are specially made to fit with these pipes form a critical part of all kinds of buildings which are being constructed nowadays. These pipes have "O" Ring type sockets on their ends to self-fit with another pipe with the help of an "O" Ring which works as a sealing ring. They form a complete sanitary discharge system of a modern building. As the pipes are very light, their installation is very easy.

"I-GRO" Grey Pipes and Fittings made under these Indian Standards are used in supplying potable water and other liquids from one point to another point. In some places though not specified in the standard, these pipes are used in bore-wells as casings and screens. Pipes are laid in fields to supply water for irrigation purpose. Very long supply lines can be designed with these pipes and fittings. Fittings such as coupler, bend, elbow, tee, reducing socket, reducing tee, socket plug, end cap, flanges and threaded adapters are made to match with the pipes. These pipes withstand internal hydrostatic pressure up-to 12.5 kgf/cm2. Pipes are made in 6 pressure ratings, i.e., 2.5kgf/cm2, 4.0kgf/cm2, 6.0kgf/cm2, 8.0kgf/cm2, 10.0kgf/cm2 and 12.5kgf/cm2.

"I-GRO" Column Pipes are a recent development. These pipes are used as riser mains from bore-wells. Column Pipes have very high tensile strength to hold the submersible pumps joined with them in the bore-well. Column pipes have come as a boon for domestic small diameter bore-wells as they reduce the total cost of a bore-well drastically. Column pipes are made in small diameter starting from 1" to big diameter of 4". Super Heavy Duty Column Pipes can hold submersible pumps up-to a depth of 1000 feet. Dimensional specifications along-with specific length of each size column pipe size are as followed:-

"I-GRO" Blue & White Pipes made under this American Standard along-with matching fittings such as sockets, reducing sockets, elbows etc. are used specifically in plumbing, as bore-well casings, for water & liquid chemical supplies and hanging of tube-well cylinders from hand pumps. Pipes manufactured to match this specification are threaded on both ends to join pipes with matching fittings to form a pipe-line system for supplying the required fluid to the discharge point. These pipes are made in three pressure ratings, i.e., Schedule-40 (Light Duty), Schedule-80 (Medium Duty) and Schedule-120 (Heavy Duty). Dimensional specifications along-with internal water pressure ratings for each size are as followed:-

"I-GRO" Blue Pipes and Screens made under this Indian Standard are used in bore-wells as casings and screens. These pipes have very good tensile strength as they are hanged up-to a depth of 250 meters (850 feet) in bore-wells. The screen pipes provide excellent water screening (filtering) while drawing ground water into the casing of the well. This system helps in drawing clean water from depths of the bore-well to the surface. Pipes are threaded according to the standards prescribed. Pipes are made in two depth ranges of casings, i.e., up-to 80 meters (250 feet) for shallow bore-wells (CS) and up-to 250 meters (850 feet) for medium deep bore-wells (CM). Screen pipes (filters) are of two kinds, i.e., Plain Screens (with horizontal slots on plain pipes) and Ribbed Screens (with horizontal slots on ribbed pipes). Slot widths are made on screens according to the grain thickness of the soil or the sand found in the bore-well. Minimum slot width is 0.2 mm while the maximum is up-to 2.0 mm. The company also makes vertical slots on the plain pipes starting from 80 mm nominal diameter.
