Well Casing Pipe
Well Casing pipe
We offer well casings and screens made of uPVC are ideal for applications like bore well/ tube well extraction of water from the water table. While lighter rigs & smaller crews suffice for drilling, they are more flexible than most metallic casings & capable of performing satisfactorily even at depths in excess of 2000 ft.
Casing Pipes as per IS:12818 available from 40mm to 400mm are ideal for Upper and Lower Casings. (Casing Medium- for depth up to 250 metres & above; Casing Shallow- for depths 80 metres & lesser)
Screen Pipes(with variable slots-2mm to 4mm) are used in conjunction with Upper & Lower Casing Pipes, Available in lengths - 2 mtrs. & 3 mtrs. or as per request.
Our uPVC Pipes as per ASTM: D1785 are used in bore wells as riser pipes.
Advantages of uPVC Casings, Screen & Riser Pipes
* Economic, costing just 2/3 of conventional pipes.
* Corrosion resistant, the pipes last at least 15 years. Much longer than conventional materials.
* Smooth inner surface discourages bacterial activity.
* Number of joints reduced due to usage of bell type of joints.
* Lightweight(1/5 of steel pipe) with excellent strength-to-weight ratio ensures easier handling, transport, storage & installation, leading to reduction in time and costs.
* Thicker trapezoidal threads, used in sizes above 4", provide better jointing.
* Elimination of white Zinc & Coir threads ( as in conventional pipes) increases longevity by resistance to corrosion, abrasion & rust.
Permanent jointing not reuired, thus permitting re-usage. The tube well system can also be solvent cemented to create monolithic joints. Conventional threaded joints also possible and can be connected to other conventional pipes.
