Finolex Column Pipes
PVC - U COLUMN PIPES
Finolex PVC-U column pipes are suitable for water extraction from the bore wells. These pipes are uniquely designed and manufactured using lead free compound on highly advanced, state-of-the-art CNC machines. Finolex column pipes have been designed to withstand system load comprising the weight of the pump, water and pipes with an adequate factor of safety.
Finolex column pipes offer many advantages, thereby emerging as the best alternative to conventional metal pipes.
Column pipes are light weight, have a high tensile load capacity, leak proof joints, have a long life, and are economical. Its square threaded coupling joint ensures ease of joining as well as an optimum load holding capacity. A high torque resistant locking system and specially designed rubber “O” ring ensure trouble-free operations.
Our stringent quality assurance approach across all stages of manufacturing gives the product a high degree of reliability, making Finolex column pipes a preferred choice for farmers, users in domestic and commercial establishments, and quality-conscious people across the country.
Finolex offers column pipes in Coupler and Bell End variants in standard lengths of 1.5 and 3 meters. These pipes are available in sizes between 25 and 100 mm (1” to 4”) diameter with a full range of pressure ratings in V4, Crystal, Medium, Standard, Heavy, and Super Heavy type as per requirements based on installation depth from 100 to 400 meters.
Column Pipe Applications
Column pipes are ideal for both urban and rural applications as they are used for efficient water extraction from borewells in either area.
Technical Details
CHARACTERISTICS OF COLUMN PIPES
Square threads
Column pipes are provided with square threads for coupling joints. Due to their unique design, these pipes can withstand considerable shock, jerk load and pressure at full capacity when operational. Square threads ensure ease in joining with a high load holding capacity.
Specially designed “O” rubber ring:
Made from EPDM rubber. It makes joints watertight and absorbs pump vibrations to ensure trouble-free operation, which extends the life of the motor and pumps Rubber Ring bearings.
Unique Locking System:
A high torque resistance and double locking system are provided by using brass riveting, which promises extra safety in the long run.
Thick and Thin Construction:
Finolex Column Pipes are specially designed and manufactured to compensate for material removal during the threading operation by maintaining a thick section at the threaded end of the pipe. For the remaining pipe, a thin size is maintained. This manufacturing process promises additional strength at the threaded end.

-
How to prevent damage/bulging of bottom column pipes, especially during the dry run of the pump?
During a dry run of the pump, the heat generated may damage the bottom column pipes. In such a case, the initial 3-meter GI /steel pipe must be connected directly with the pump for proper heat dissipation before it reaches the column pipe. Alternatively, a hand-operated valve at the top of the borewell should be installed, keeping it partially open which limits, the water flow ensuring that the pump does not go dry.
