Turbine Bolting
Delta Fitt Inc is a reputable Turbine Bolting Manufacturer which provides heavy-strength fasteners that were designed with high-pressure and high-temperature applications in power and energy equipment. The bolts are designed to support turbines at extreme loads of operation where failure is not acceptable. They come in the form of steam, gas and hydro turbines most commonly to hold the casings, blades, rotors and other main assemblies. Made of alloys that are resistant to high temperatures, turbine bolts do not lose their structural integrity under highly challenging conditions of thermal expansion and contractions.
Common Materials & Grades for Turbine Bolting
| Standard | Grade | Material Description | Typical Max Temp |
|---|---|---|---|
| ASTM A193 | B7 | Cr-Mo alloy steel | ~450 °C |
| ASTM A193 | B16 | Cr-Mo-V alloy steel | ~540 °C |
| ASTM A193 | B6 | Martensitic stainless steel | ~500 °C |
| ASTM A193 | B8 / B8M | Austenitic stainless steel | ~600 °C |
| ASTM A320 | L7 | Low-temperature alloy steel | −100 °C to 450 °C |
| ASTM A453 | 660 | Precipitation-hardening SS | ~700 °C |
These Bolts are designed to give a reliable service in rotating machines where the pressure, vibration, and thermal stresses are unremitting on large B2B energy and infrastructure projects. Their strong clamping force prevents deviation in form of repetitive cycles of loads. Turbine bolts can be found in different grades, dimensions and finishes that are specific to the exact needs of the power plants, marine equipment and aerospace turbines. They are built to be reliable and this reduces the maintenance rate and allows the machinery to be in operation with reduced time lost.
