SPECIAL COMPOUND :
Astral Column pipes are manufactured from “METAL FREE” uPVC compound material especially developed by using “JAPANESE TECHNOLOGY” to sustain best column loads, pressure and also encounters the high impact developed during handling, storage and installation. Due to this special compound the TENSILE property of pipe increase which is being tested rigorously using modern testing equipment.
STUD LOCK SYSTEM :
Every pipe is fitted with coupler having “Stud Lock” a unique system developed by Astral, which ensures that during installation, application or removal of system, the coupler will never dethread from the pipe.
100% HYGIENIC / SAFE FOR DRINKING WATER :
Supply of drinking water is 100% hygienic and safe as being pumped through ASTRAL uPVC column pipes manufactured from special METAL FREE compound right from the origin of water source beneath under the earth at maximum depth.
ANNEALING ON PIPES :
Every pipe is annealed during manufacturing which is a very special technique developed by ASTRAL. This will really enhanced the mechanical properties of pipes which make sure that the pipes will perform best during application.
EPDM ‘O’ RING :
Specially designed "O" rings provided on the threads makes the joints watertight and absorb pump vibrations. These “O” rings are made from EPDM rubber which is most suitable for drinking water option.
SQUARE THREADS :
Unique square threads made on CNC machines provide sufficient grip and additional strength against tensile load. Thus the joint become fairly strong with sufficient factor of safety to take care of load of entire assembly with pump weight. These specially designed threads also make it suitable for easy fitment.
THIN AND THICK PROCESS :
The pipe ends are specially given the effect of additional wall thickness by using Thin & Thick process to compensate the strength and load bearing capacity caused due to threading of pipes. The effect of Thin & Thick is given to all sizes considering the working conditions & load factor.
FIELDS OF APPLICATIONS :
Water rising for submersible and jet pump for irrigation, domestic and industrial applications. Ideally suitable for long term use in safety, sandy and chemically aggressive water.
