Casing Pipes As Per ASTM D 1785

Newly introduced heavy-duty casing pipes as per ASTM D-1785 specifications to cater to the market needs. These pipes are available in SCH 40 and SCH 80 varieties. These pipes are strong and durable with higher stiffness as compared to IS:12818 pipes available in the market.

Manufactured according to ASTM D 1785, these pipes are available from 40 to 300mm sizes in SCH 40 and SCH 80 classes.


Wide varieties - Supreme offers varieties of casing pipes to suit different application requirements in the borewell sector.

Excellent corrosion resistance - Unlike steel pipes, uPVC casing pipes are completely immune to corrosion and offer good resistance to aggressive elements in the soil which could cause encrustation of well screens.

Light in weight - These pipes are light in weight which makes their transportation and installation easy and cheaper than conventional materials. These advantages particularly manifest themselves in rural areas where they are most needed but due to poor roads, transportation is difficult.

Quick and convenient installation - These pipes are provided with good quality threaded joints, due to which they can be easily assembled and installed, where drilling is done by hand with a lightweight drilling rig or even with large-capacity drilling machines.

Excellent strength and stiffness - These pipes have excellent stiffness and meet all the mechanical properties as per IS:12818. They have excellent hydrostatic collapse pressure capable of withstanding the external hydraulic pressure that these pipes would be subjected to during the construction of the well.

Non-toxic - The material of the pipe is non-toxic and hence does not impart any taste, odour, or colour to water. It also does not release any harmful substances into the water which could pose health problems. It also resists bacteria, making it completely safe for drinking water.

Non-conductive - uPVC is a non-conductor of electricity, eliminating any electrochemical reactions with groundwater that could cause the encrustation of screens.

Long lasting - As the material is free from rusting, weathering, and chemical reactions, and with excellent mechanical properties, Supreme casing pipes last a lifetime.

Economical - Apart from all the advantages listed above, Supreme uPVC casing pipes and screens are the most economical borewell solution as compared to other materials or even alternative uPVC casing pipes available in the market.
