Pressure Vessel & Boiler Plate · pressure-vessel plate for reactor and column shells, heat-exchanger shells, boiler and steam drums, LPG and ammonia storage spheres, and hydrotreater vessels
This European Standard specifies requirements for flat products for pressure equipment made of weldable fine grain steels as specified in Table 1. NOTE 1 Fine grain steels are understood as steels with a ferritic grain size of 6 or finer when tested in accordance with EN ISO 643. The requirements and definitions of EN 10028-1:2017 also apply. NOTE 2 Once this European Standard is published in the EU Official Journal (OEU) under Directive 2014/68/EU, presumption of conformity to the Essential Safety Requirements…

Limits as specified in EN 10028-3:2017. Where the standard sets different values by thickness or product analysis, each band is shown separately.
P275NL1 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.
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.
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.
Send the grade or the standard you specify, the thickness range, quantity and destination port. We reply with price, lead time, delivery term and the applicable certificate within 12 hours (Mon–Sat, GMT+8).
