Raw Material and Process Flow

Radiators are manufactured from CRCA steel strips D.D (IS 513) grade 1.0 mm to 1.25 mm thick for radiator fins as per customer requirements
CRCA steel strips D.D grade 2.0 mm thick for header pipes in 75 mm or 90 mm diameter as per customer requirement. Larger headers of 100 NB and 150 NB are also available as per customer requirements
Accessories such as m.s square / round flanges, air vent, drain plug, lifting hooks, bracing straps are standard but can be supplied as per customer specific requirements.

Internal Surface Preparation

The internal surface of the Radiators are washed and cleaned to avoid transformer oil contamination with oil for transformers according to ISO 4406 and coated (flush coating) with varnish. Internal surface painting can also be arranged as per specific purchaser requirements.

External Surface Preparation

Our standard products are de-greased prior to painting with two coats of zinc chromate red oxide primer to prevent corrosion. Finished painting is done by enamel / epoxy paint or as per customer specification. Sand / quartz / grit blasting as per customer requirement. We have a surface treatment section equipped with steel shot blasting machine and painting system.

Tests

All Radiators are pressure tested individually for leak proofness, under water at an air pressure of 200 kPa (2kg/ cm2) for 30 minutes. (Standard water immersing test). Compliance is checked by immersing the Radiators in a water filled tank. Randomly selected Radiators from all consignments goes through hot oil test. (the Radiators are filled with transformer oil at a temperature of 600 C and kept at a pressure of 200 kPa ( 2.0394 kgf/ cm2) for 3 Hours to ensure no oil leaks.

External surfaces of the Radiators are checked for deformations.

Inspections

I. Dimension and tolerances check
II. Visual inspection for welding
III. Internal surface check for presence of any foreign bodies or contamination
IV. Paint peel off test (inspection of external paint).

Preparation for Transportation and Storage

Our Quality Control Division carries out one final check for radiator cleanness, foreign bodies and other contamination. The Radiators passed trough a stringent checking system developed by our qualified engineers and technicians.

Flanges are covered to prevent the ingress of contamination during transportation or storage. We take all possible measures to avoid mechanical damages to the Radiators.

With our radiators, we try to serve our customers to reduce their costs through savings on fluids due to our superior heat transfer, and the reduction of number of elements per radiators per transformer (reducing labor, handling, etc.)
