EZHONG provides high-performance plate rolling solutions for pressure vessel manufacturers, supporting the fabrication of shells, storage tanks, reactors, heat exchangers, boilers, and other critical cylindrical components.
With decades of experience in heavy plate forming, EZHONG machines are engineered for thick plate processing, large diameter shells, and demanding manufacturing standards, helping customers achieve accurate forming, reliable welding performance, and long-term structural safety.
Pressure vessels are essential equipment widely used in industries such as:
● Oil & gas
● Petrochemical
● Nuclear power
● Energy storage
● Hydrogen energy
● Chemical processing
● Power generation
Manufacturers must transform steel plates into high-precision cylindrical shells, cones, and other components while meeting strict requirements for:
● Dimensional accuracy
● Roundness control
● Welding alignment
● Material performance
● Structural reliability
For large pressure vessels and storage tanks, stable plate rolling is a critical process that directly affects final assembly quality, pressure resistance, and operational safety.
Pressure vessel manufacturers often process thick plates and advanced materials, including carbon steel, stainless steel, low alloy steel, and high-strength pressure vessel grades. These materials require high rolling force, rigid machine structures, and optimized forming processes.
Pressure vessel shells require excellent geometry control to ensure proper longitudinal welding, accurate nozzle installation, reliable pressure performance, and reduced post-welding correction. Poor roundness may increase assembly difficulty and affect manufacturing efficiency.
Large storage tanks, reactors, and industrial vessels require large working widths, strong bending capacity, and stable forming of oversized cylinders. Manufacturers need equipment capable of handling different diameters and thickness ranges within one production facility.
Pressure equipment industries operate under strict quality systems, including ASME and other international standards. Stable and repeatable plate forming is essential for achieving consistent manufacturing quality.
EZHONG provides customized plate rolling solutions for manufacturers of pressure vessels, storage tanks, reactors, heat exchangers, and heavy industrial equipment.

Stress-free leveling applies a carefully controlled pressure curve that minimizes residual stress introduction. Traditional leveling applies uniform high pressure, creating internal stress concentration. When the finished vessel undergoes post-weld thermal stress relief cycles, pre-existing residual stress can trigger stress-relief cracking. EZHONG's graduated pressure curve prevents this. Material tensile testing post-leveling shows <1% strength loss vs. 5-10% traditional.
Yes. The machine logs all leveling parameters in real-time (pressure history, deflection compensation, operator ID, timestamp). Upon completion, it auto-generates ASME Section VIII Division 1 & 2 compliant documentation packets. Manual documentation typically requires 40+ hours per batch; EZHONG auto-generation takes <15 minutes. Documentation is audit-ready for third-party inspection.
Multi-row support roller matrix (4-7 rows upper/lower beams) with individual proportional hydraulic cylinders per support roller. Real-time deflection monitoring triggers automatic support roller adjustment to maintain linear straightness ±1.0mm. This prevents upper/lower beam sagging that would otherwise concentrate stress at outer fiber of thick plates.
Payback period: 16-18 months. ROI driven by: scrap reduction (€308K/year), maintenance savings (€67K/year), total Year 1 savings €375K less €38K operating costs = €337K net. Equipment cost €280K fully paid by Month 10, with €54K surplus by Month 18.
Yes. Standard integration includes production batch tracking (material lot → vessel ID), quality data export (flatness measurements, compliance docs), compliance report generation (ASME/PED packets), and API connectivity for custom integrations. Integration typically requires 2-3 days configuration; no equipment re-engineering needed.
