Riser/ Drop/ Column Pipes are used in the erection of submersible borehole pumps up to depth of 1000 feet. These Pipes are fitted with a locking system and coupler assembly, in which a stainless steel wire is wound between the coupler and pipe to ensure that during installation and removal of pumps the joint does not open up, resulting in column slippage. These Pipes are made using quality grade material that ensures fine finish and long lasting usage. Riser/ Drop/ Column Pipes are light in weight and ensure no rusting, corrosion or deterioration.
