Clean rolling oil cooling grills at steel mills

Status: The steel factory announced Hesco support due to the Hisaka radiator model UX-926-KNHP-91 having poor heat exchange and increased pressure loss. After survey, we recommend removing the blister for cleaning. With many years of experience in blister cleaning maintenance, the factory chose Hesco for this job to ensure the shortest maintenance time within 2 days according to the factory’s shutdown schedule.

The UX-926 set is a model with a large size of over 3m high, weighing more than 5 tons, we sent engineers, skilled workers and full specialized tools from Hisaka.

Some pictures during the cleaning process:

The heat exchanger plate contains a lot of residual oil, blocking the flow, causing pressure loss and poor cooling

Lots of trash

After cleaning off trash and oil residue, we install and tighten the bolts as before -> pressure test with the pump system to meet design specifications.

The factory runs acceptance tests within 1 week to evaluate cooling performance. The factory evaluated the results very well and accepted Hesco’s maintenance work.
