Industrial Supply for Process Equipment from
Parvan Toos Steel Complex
Steel plates used in the fabrication of pressure vessels are among the most critical flat steel products for the energy, chemical, and process industries. These vessels operate under specific internal pressure, temperature, and mechanical loading conditions. Therefore, the quality of every steel plate and steel sheet directly affects equipment safety, service life, and long-term operational reliability.
At parvan, the development of industrial flat products is focused on supplying reliable materials for demanding engineering applications. As part of its production portfolio and expansion strategy, parvan steel supplies hot rolled steel plate and hot rolled steel sheet suitable for pressure vessels, process equipment, and heavy-duty industrial structures.
The Role of Steel Plate and Steel Sheet in Pressure Vessel Engineering
In oil and gas, petrochemical, power generation, and process industries, pressure vessels are used for storage, processing, and transfer of fluids under controlled operating conditions. These applications typically rely on carbon steel plate, carbon steel sheet, and in some structural parts, structural steel plate.
Plates used for pressure vessels must reliably withstand:
-
High internal pressure
-
Continuous temperature variations
-
Combined mechanical and thermal stresses
-
Repeated operating cycles
For this reason, the selection of a high-quality hot rolled steel plate with stable hot rolled steel plate thickness and uniform microstructure is essential.
parvan Steel’s Manufacturing Approach for Pressure Vessel Plates
At parvan steel, industrial flat products are manufactured through slab rolling technology. This production route enables the supply of heavy hot rolled steel plate and hot rolled steel sheet suitable for fabrication of industrial equipment and pressure vessels.
By controlling rolling parameters and metallurgical conditions, each delivered steel plate and steel sheet is optimized for forming, welding, and structural integrity. In addition, plates can be supplied for further processing, including heat treatment, when project specifications require enhanced mechanical performance for pressure equipment.
Dimensional Specifications of Pressure Vessel Steel Plates
The current production range of parvan for pressure vessel and industrial equipment applications includes:
Product type: carbon steel plate and carbon steel sheet for industrial use
Manufacturing process: Hot rolling (Hot Rolled Plate)
Current thickness range: 20 – 40 mm
Standard width: 1250 mm
Standard length: 6000 mm
Delivery form: steel sheet
This range covers standard heavy products such as the 20 mm hot rolled steel plate, which is widely used for shells and main components of industrial pressure vessels.
ST37 Steel Plate and ST37 Steel Sheet for Industrial Pressure Equipment
For general industrial and structural applications related to pressure equipment, ST37 steel plate and ST37 steel sheet are commonly applied.
From a technical perspective:
-
The controlled ST37 chemical composition supports good weldability and stable forming behavior.
-
Balanced ST37 mechanical properties provide adequate strength and ductility for fabrication of shells, nozzles, and supporting structures.
-
For international documentation and multi-standard projects, engineers often refer to ST37 equivalent steel grades for cross-standard verification.
Phase Two Development Program for Pressure Vessel Plates
To support the increasing demand for thinner and medium-thickness plates used in industrial vessels and process equipment, parvan steel has defined a second-phase expansion plan.
Planned thickness range: 8 – 15 mm
Annual production capacity: 150,000 tons
Main applications:
-
Industrial equipment
-
Pressure vessels
-
Process and energy-related structures
This expansion strengthens the supply of lighter steel plate and hot rolled steel sheet for modern pressure vessel fabrication.
