What is the material of steam turbine blades?
Blades under high and medium pressure are usually made of stainless steel from 12Cr, but are made of stainless steel at temperatures above 450 degrees, because stainless steel has better properties at high temperatures.
What are the two types of steam turbines?
Steam turbines may be classified into different categories depending on their construction, working pressures, size, and many other elements. But there are two basic types of steam turbines which are called impulse and reaction turbines.
What is material selection of steam turbine?
13.3. 2. Material selection
| Component | Material | Nearest ASTM equivalent |
|---|---|---|
| Stationary blades | Nodular cast iron | A536 60-40-18 |
| 12CrNiMo | None | |
| 12CrNi | A240 410 | |
| Diaphragm rings (impulse technology only) | 12Cr | A276 403 |
What material is used in turbine casing?
LP cylinder casings are generally fabricated from carbon steel, although the inner cylinder may be cast from spheroidal graphite iron.
What are the five types of steam turbine?
While based on the flow of steam they can be classified as a single flow, double flow and reverse flow turbines. Similarly, based on exhaust conditions, there are five main types of steam turbines; condensing, non-condensing, automatic extraction, mixed pressure, and regenerative extraction.
What are jet turbine blades made of?
The low-pressure compressor blades and several high-pressure compressor blades are made of Ti-6Al-4V alloys which are also used for the fan blade, and the rest of high-pressure compressor blades are made of Ni-based superalloys such as Hastelloy X.
What material is used as a grouting for steam turbine?
Conbextra GP2 is used for precision grouting where it is essential to withstand static and dynamic loads. Typical applications would be the grouting of base plates of turbines, compressors, boiler feed pumps etc., It can also be used for anchoring a wide range of fixings.
