Enamel Coating

Enamel Coating (formerly known as Coal-tar Enamel Type 1 Plasticised Pitch) is hot pour coal tar enamel coating prepared by digesting bituminous coal in a solution of pitch and high boiling coal tar distillate modified by inert mineral filler. It conforms to IS 9912 : 2008 Type 1 & 2, BS 4164: 2002 and AWWA C 203 : 2015, Type 1.

Please see Annexure 1 attached herewith.

Corrosion protection of pipes for carrying crude, liquid or gases by coating pipes.

Cathodic disbonding resistivity

Excellent adhesion to metal, high electrical resistivity, good flexibility, temperature susceptibility and chemical stability.

Resistant to bacteria / marine organisms, root growth, back fill damage, petroleum products and water.

Depending upon the size of the melting kettle, cut ShaliEnamel into small pieces of approximately 1 to 5 kg each.

Fill the kettle up to 40% of its capacity.

Begin heating till the application temperature is attained. During heating, slowly add balance material upon reaching fluidity.

Stir occasionally to avoid carbonisation at the bottom of the kettle. This will prevent coking of the material and save considerably on fuel.

Consume the heated ShaliEnamel within 3 hrs once the application temperature is reached. Reject enamel held at the application temperature for more than 3 hrs, if it is found off specification.

Ensure enamel remaining in the kettle on reheating does not exceed 10% of fresh charge.

Resist the maximum temperature of the kettle to 260 OC. Reject enamel above this temperature.

In the event of Plant breakdown, or any other reason, put off burner and bring down the enamel temperature to 180°C or lower keeping agitator on for a period not exceeding 8 hrs.

Apply ShaliEnamel on cleaned and primed external pipe surface when metal temperature is above 7 OC to ensure that the pipe is free from dust, dirt, oil and moisture.

Available in 250 kg drum.
