Key Applications Where SA 387 GR. 11 CL. 2 Delivers Efficiency & Safety

SA 387 GR. 11 CL. 2 is the material of choice for critical equipment where efficiency and safety are interdependent:

1. Tube Shell Heat Exchangers (Core Application)

In refineries, power plants, and petrochemical facilities, tube shell heat exchangers fabricated with SA 387 GR. 11 CL. 2 plates:

Handle high-temperature fluids (450–593°C) like superheated steam, crude oil, and catalysts.

Ensure leak-free operation with high-pressure resistance (up to 30 MPa), preventing hazardous fluid spills.

GNEE's custom tube shell heat exchangers use SA 387 GR. 11 CL. 2 for shells, tube sheets, and baffles-optimizing heat transfer while meeting global safety standards.

2. Petrochemical Reactors & Separators

Hydrocracking/Hydrotreating Reactors: Resist hydrogen attack and SSCC, ensuring safe, efficient conversion of crude oil to high-value products.

Fractionators & Separators: Withstand cyclic pressure and temperature changes, maintaining separation efficiency without downtime.

3. Boiler & Steam Generation Equipment

Boiler Tubes & Superheaters: Operate at 550–593°C, delivering reliable steam production for power generation.

Heat Recovery Steam Generators (HRSGs): Capture waste heat efficiently, reducing energy costs while withstanding flue gas corrosion.

4. Offshore & Sour Service Equipment

Offshore oil/gas platforms rely on SA 387 GR. 11 CL. 2 for pressure vessels and piping, as it combines weight optimization with sour service resistance.
