What is the material of steam turbine air cooler? How to deal with frozen tube bundles of air cooler?

There are two types of equipment for steam turbine air coolers used in power plants.: ACC-direct air cooling IDCT-indirect air cooling two types of equipment have different tube bundle forms and materials. ACC-single row tubes (also called large flat tubes): Base pipe material-carbon steel coated with aluminum ； Fins - Aluminum fins. But in the chemical industry, ACC has other forms of tube bundles - BIWA tube bundles - steel base tubes wrapped with corrugated aluminum fins IDCT - 4 rows or 6 rows of tubes: Base tube material - aluminum tube, fin material - aluminum fins. Freezing cracks in the pipe bundles must be repaired in time, otherwise the freezing will continue to spread and cause irreversible damage to the unit. Measures after pipe bundles freeze and crack: 1. If the number of freezing damage is small, lining or blocking can be used, which will definitely affect the heat dissipation performance of the equipment. 2. Find the original design manufacturer to purchase pipe bundle spare parts and replace them.

We manufacture stainless steel or carbon steel seamless tubes and aluminum alloy rolled fin heat pipes

The air cooler of the turbine generator consists of coiled spring type, fin type, and through-plate type. The materials include copper+copper, copper+aluminum, stainless steel, titanium tube, etc. This kind of air cooler usually has several units in a group. If it leaks, the pipe will only be blocked and then replaced.

If it's too little, it'll be blocked. If it's too much, you won't know.

Call a professional for repairs, I'm the one

If it's too little, plug it; if it's too much, replace it.
