Carbon Steel Seamless Pipe, ASTM A106 GR.B Studded Tube, For Radiant Tube in Furnace
Studded tubes made from ASTM A106 Grade B carbon steel are specially designed for heat transfer enhancement in high-temperature furnace applications. In radiant sections, they are commonly used in petrochemical furnaces and reformers where high heat flux and gas exposure occur.
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.30 |
| Manganese (Mn) | 0.29 – 1.06 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.035 |
| Silicon (Si) | ≤ 0.10 |
| Property | Value |
|---|---|
| Tensile Strength | ≥ 415 MPa |
| Yield Strength | ≥ 240 MPa |
| Elongation | ≥ 20% |
| Hardness (optional) | ≤ 179 HB |
Increased heat transfer area in direct flame zones.
Efficient fouling resistance—ideal for gas-side heat transfer.
Strong bonding between stud and tube via welding.
Durable in extreme furnace conditions, resisting scale and thermal stress.
Radiant Section: Main heating zone exposed to combustion gases.
Petrochemical heaters, reformers, crude heaters, ethane/ethylene crackers.
Often used as convection replacement in hot zones where fin tubes can’t survive.
