SA387-11 Plate

Pressure-containing equipment plays a crucial role in the storage, transport, and treating of process media, from hazardous gases and valuable crude oil to harmful sewage and essential drinking water. While all products designed for under-pressure use are fabricated from high-quality materials to safeguard against leakage and degradation, devices operating at heightened temperatures or handling hot process media must be constructed from high-performance materials like ASME SA387-11 steel plate.

Benefits of SA 387 Grade 11 Plate

ASME SA387-11 steel plate is a pressure vessel grade steel specially designed for use in elevated temperature service and applications in which sour gas is present. Sometimes called chrome-moly plate, higher levels of chromium provide excellent corrosion and oxidation resistance. Additional characteristics of SA387-11 steel plate, which is also referred to as ASTM A387-11 steel plate, include: 

  • Greater temperature resistance 
  • Improved tensile strength 
  • Anti-rust properties 

 

Typical Requirements

Universal Steel America stocks SA387-11 steel plate with thicknesses from 3/16 to 6 inches in the normalized and quench-and-tempered conditions. Width and length restrictions exist, depending on plate weight and mill capabilities. Typical widths are 96 and 120 inches, whereas standard lengths are 240 and 480 inches. Specialized testing and chemical or physical requirements can vary, depending on the final application requirements. Common uses for SA387-11 steel plate include: 

  • Pressure vessels
  • Tubing 
  • Flanges
  • Piping
  • Heat exchangers 
  • High-temperature ducting 
  • Pipe clamps
  • Valves

Applications & Characteristics 

While SA387-11 steel plate is an excellent choice for use in a variety of applications, it’s ideally suited for oil and gas and petrochemical industries. In these sectors, liquids and gases are often stored at higher temperatures, and, occasionally, sour gas may be a concern. 

Sour gas contains significant amounts of hydrogen sulfide, or H2S, and is dangerous. SA387-11 steel plate’s chemical and mechanical characteristics provide superior protection against sour gas.   

Universal Steel America can provide third-party simulated post-weld heat treatment, or SPWHT, per customer or end-user specifications. This ensures the product has optimal performance characteristics for the final application operating environment. 

For applications demanding higher performance characteristics than standard stock and code requirements, Universal Steel America has you covered. We have an extensive range of mill sources strategically positioned around the world that are capable of producing material to meet precise job needs.
