Pressure Vessel Plates

Both shell plates and heads.

We deliver pressure vessel steels for  the vessel and apparatus industry.  Our  pressure vessel plates are mainly used in the chemical and petrochemical industry.

Our high-temperature pressure vessel steels show best results in particular use with elevated temperatures like in steam boilers and hot application pressure vessels. 

9 % Nickel steels are used for the construction of storage tanks for liquid natural gas.

 We can also offer selected steel grades in sourgas resistant condition. 

Advantages

We deliver both shell plates and heads. The benefits for our customers are as follows:

  • Advantages in processing, best welding properties and workability when using steel from one single source for shell plates as well as heads.
  • Technical assistance and coordination from one department quality and research.
  • Simultaneous production and delivery  of shell plates and heads. 
  • Smaller expenditures in purchasing for the customer.
