SPV355 container plate delivery state: SPV355 steel plate thickness less than 40mm choose hot rolled state delivery, steel plate thickness greater than 40mm choose normalized state delivery. The purpose is to reduce the internal stress of the steel plate.
SPV355 steel plate delivery state introduction:
SPV355 steel plate default normalized state delivery
SPV355 steel plate thickness extension can be done; Z15, Z25, Z35
SPV355 steel plate thickness flaw detection can be done; 1 probe, 2 probe, 3 probe
SPV355 steel plate thickness the thicker the more difficult to meet the flaw detection, commonly used specifications 20-130 can be guaranteed a probe,
Above 130-200 can satisfy 2 probes or German standard three probes.
PV355 steel plate can be hot rolled, normalized heat treatment process state delivery, generally for the requirements are not high you can use hot rolled on the line, but some of the requirements are higher, or to use normalized heat treatment process. Widely used in petroleum, chemical, power station, boiler and other industries, used in the production of reactors, heat exchangers, separators, ball tanks, oil and gas tanks, liquefied gas tanks, nuclear power reactor pressure shell, boiler ladle, liquefied petroleum gas cylinders, hydropower station high-pressure water pipe, hydraulic turbine worm shell and other equipment and components.
