Our company according to the requirements of customers in the boiler tube, boiler tube plate evenly surfacing a layer of wear-resistant, corrosion-resistant surfacing material. The main surfacing materials are inco622, inco625, ER309L and MG250.
1. Chemical corrosion.
2. Abrasive wear.
3. High temperature corrosion.
4. In the actual operation of various boilers, the serious thinning of the tube wall is not caused by a single factor, but is often the result of the above three kinds of corrosion. Because nco622 and inco625 materials have strong high temperature oxidation resistance, resistance to various super acid corrosion, excellent strength and toughness at high temperature, and good processability, It is usually used by customers for surfacing under complex working conditions.
Application
Use for heating saturated steam, steam temperature could be up to 900 degree C.
Superheater Capacity Upgrades to Increase Power Generation
Send us required technical data, such as steam capacity, pressure, required temperature etc. We will design accordingly.
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. |
