Jetting (Spray) Scrapers

Jetting (Spray) Scrapers

Injection or batching of corrosion inhibitor fluid can help reduce pipeline deterioration, but gravity naturally forces the inhibitor to settle along the bottom of a pipe, leaving the top of the pipe unsaturated and most vulnerable to corrosion. IKS Corrosion Inhibitor Spray Scraper is designed to defy gravity by spraying corrosion inhibitors onto the inside top portion of multi-phase gas gathering or gas transmission pipelines.

The Spray Scraper works based on the dynamics of bypass flow and differential pressure, with no moving parts or pressure vessels to fill and charge. Instead, the Spray Scraper allows the higher pressure to flow through its body and spray head. Bypass flow acts as the accelerant to transfer and vaporize fluid while creating a low-pressure area in the spray nozzle as it passes through. This pressure drop creates a vacuum at the Spray Scraper front inlet ports, and this vacuum draws up residual corrosion inhibitor that has settled on the bottom of the pipe.
