Frequently Asked Questions About ASME Pressure Vessel Plates
- What is ASME pressure vessel quality (PVQ) steel plate?
ASME Pressure Vessel Quality (PVQ) steel plate is carbon or alloy steel manufactured to ASME specifications for boilers, pressure vessels, heat exchangers, storage tanks, and other pressurized equipment. Common grades include SA516 Grade 60, 65 & 70 plate.
- Why is SA516 Grade 70 the most commonly specified pressure vessel plate?
SA516 Grade 70 offers an excellent combination of:
- Strength
- Toughness
- Weldability
- Availability
- Cost-effectiveness
Because of these properties, it is one of the most widely used materials for pressure vessels, storage tanks, and heat exchangers worldwide.
- What thicknesses of ASME pressure vessel plate are available?
Universal Steel America supplies pressure vessel plate in thicknesses ranging from 3/16" through 12", depending on grade, mill production capabilities, and project requirements.
- What supplemental testing is available for PVQ plate?
Available testing includes:
- Ultrasonic Testing (UT)
- Hardness Testing
- Impact Testing
- Through Thickness Testing (Z-Test)
- HIC Testing
- NACE MR0175 / MR0103 Compliance
- Magnetic Particle Testing (MT)
- What is HIC-tested pressure vessel plate?
Hydrogen Induced Cracking (HIC) tested plate is designed for sour service environments where hydrogen sulfide (H₂S) exposure may occur. HIC testing is commonly required in refinery, petrochemical, and offshore applications.
