Corrosion Resistance Carbon Steel Convection Superheater For Power Station Boilers
Product Description
Corrosion resistance in an extensive range of marine and chemical environments. From pure water to nonoxidizing mineral acids, salts and alkalis.
This alloy is more resistant to nickel under reducing conditions and more resistant than copper under oxidizing conditions, it does show however better resistance to reducing media than oxidizing.
Good mechanical properties from subzero temperatures up to about 480C.
Good resistance to sulfuric and hydrofluoric acids. Aeration however will result in increased corrosion rates. May be used to handle hydrochloric acid, but the presence of oxidizing salts will greatly accelerate corrosive attack.
Resistance to neutral, alkaline and acid salts is shown, but poor resistance is found with oxidizing acid salts such as ferric chloride.
Excellent resistance to chloride ion stress corrosion cracking.
Details
All the raw materials will be firstly made pipeline cutting.
It is consisted of a series of bare oil(carbon steel,alloy steel,or durable heat steel) and header and other auxiliaries. TubesΦ32,38,42 and so on,also as the request.
With the artistic apperance and accurate size,the advance process for bending tube and welding,the first rate test equipment and sophisticated technology
Differences
| Type | Advantages | Disadvantages | Supporting method |
| Pendant-type | 1.Firm structural support | 1. Flow blockage by condensed steam 2. Needs slow restart to purge the water that accumulates in the bottom. | supported from above |
| Inverted-type | 1.Proper drainage of the condensed steam | 1. Lack the structural rigidity, especially in high speed gas flow | Supported from below |
| Horizontal -type |
1. Proper drainage 2. Good structural rigidity. |
1. They do not view the flam directly so they are mainly from the convective type | Usually supported in the vertical gas ducts parallel to the main furnace. |
