Description

The obvious advantage of Air cooled fluid cooler is that it does not require any water after its first charge. This is completely a closed circuit system. The hot fluid (water) from the source is made to pass through finned surface heat transfer coils & using the heat is rejected to ambient air passing through coils using axial fans.

ADVANTAGES

Cooling media is only free air.

• Water treatment plants and chemicals not required.

• Does not require any tube well boring.

• No problem of scale formation.

• No dreation of DG set due to scale formation.

• Cooling Tower and Shell & Tube Heat Exchangers are not required.

• Raw water pump is not required.

• ubstantial energy saving during mild weather conditions.

• No fear of air contamination or pollution.

• Total Maintenance free system.

• No Engine downtime for maintenance.

APPLICATIONS

• Diesel Engine Gensets.

• Steam turbine exhaust steam condensing.

• Charge air cooling.

• Lubricating oil cooling.

• Exhaust steam condensing.

• Furnace cooling. Oil cooling.

• Hydraclic oil cooling.

• Quenching oil cooling. For more detail down load PDF >>

Testing and Inspection

• All lined pipe and fittings are subjected to 10-15 KV ( SPARK TESTING) non-destructive electrostatic test which is carried out to detect any defects in the liner such as pin holes, porosity, cracks, etc.
• All lined pipe and fittings are subjected to the visual inspection to detect any defects such as
• liner surface cracks, deformation, outside paint coating, etc.
• Storage and Handling Requirements
• PP lined fittings shall be stored in a shaded area on wooden supports.
• Avoid dropping or impacting lined pipe and fittings with heavy objects or storing near high traffic areas.

Rubber Lined Vessels, Tanks, Pping etc.

Rubber lining :

• The process of rubber lining is divided in to the following steps.
• Preparation of the base surface.
• Preparation of rubber sheets.
• Application of the rubber sheets on the metal surface.
• VULCANIZATION
• Testing & Inspection

Surface Preparation :

This is very important process for rubber lining. The surface of the METAL MUST BE FREE FROM OIL, PAINT, SCALES, RUST ETC. THIS IS GENERALLY REMOVED WITH THE HELP sand blasting/ shot blasting. After the surface is cleaned, adhesive or bonding agent is applied to surface. Two or three coats are applied, as adhesion is an important process for rubber lining.

Preparation of rubber sheets :

The rubber compound is manufactured as per the requirements after looking in to the chemical and other conditions of the process. Rubber sheets are made on calendar machine in different plies. Lining up to 6 mm thickness can be applied in single layer. If the thickness is more, it is applied in 2 or more layers. For Pipes & fittings Extruded rubber tubes are inserted in the Pipes .
