Astral 2.1/2 inch UPVC Column Pipe For Submersible Pump are well known for the finest quality with the most accurate dimensions. UPVC Column Pipe is threaded in the hi-tech CNC machine to improve the performance of the column pipe. It is combined with a unique square thread to provide sufficient grip and additional strength against the tensile load. These pipes in astral submersible pumps are given the special effects of additional wall thickness by using a thin and thick process. 2-inch column pipe is done to compensate for the strength and load-bearing capacity caused due to the threading of the pipes. This pipe column is eco-friendly due to the lead-free, and heavy metal-free compound used while manufacturing the pipes. The double stud pin locking system is included to ensure the safety and reliability of the system.
