Typical applications

SB480M is normally specified for reactor and column shells, heat-exchanger shells, boiler and steam drums, LPG and ammonia storage spheres, and hydrotreater vessels.

We supply it cut to size by plasma, laser or waterjet, with edges machined or flame-cut to your drawing, and can deliver in the heat-treatment condition your fabrication procedure requires.

Two vessel heads cut from pressure-vessel steel plate and wrapped for export
Vessel heads cut to drawing from pressure-vessel quality plate, wrapped and strapped for sea freight.

Delivery condition

Supplied in the heat-treatment condition the standard requires for the grade — as-rolled, normalized, normalized and tempered, or quenched and tempered. Simulated post-weld heat treatment can be carried out and reported before shipment.

Available forms and services

  • Plate 6 – 200 mm thick, width to 4 000 mm, length to 14 000 mm
  • CNC plasma, flame and laser cutting from your DXF / DWG drawing
  • Normalizing, quenching and tempering, and PWHT simulation
  • Edge bevelling, drilling, rolling to diameter on request

Inspection and certification

Mill test certificate to EN 10204 3.1 / 3.2; Ultrasonic testing to EN 10160 (S1–S3) or ASTM A578; HIC to NACE TM0284 and SSC to NACE TM0177; Simulated post-weld heat treatment (PWHT) on request; Third-party inspection by SGS, BV, TÜV or Intertek

Seaworthy packing — bottom skids, steel strapping, VCI film and edge protection — is standard for sea freight. Container loading plans with piece weights are issued before shipment.
