GNEE Steel specializes in the supply of boiler and pressure vessel steel plate ex-stock to fabricators and ASME stamp manufacturers across SE Asia. Pressure vessel steel plate is used for many applications where the pressure inside is significantly higher than atmospheric pressure. It is treated differently to many other steels because the consequences of failure can be catastrophic – if for example a plate failed the results could be the release a cloud of toxic chemicals  or explosive vapour and a high number of fatalities.

What is Pressure Vessel Steel Plate?

Pressure vessel steel plate covers a range of steel grades that are designed for use in pressure vessel, boilers, heat exchangers and any other vessel that contains a gas or liquid at high pressures. Familiar examples include gas cylinders for cooking and for welding, oxygen cylinders for diving and many of the large metallic tanks that you see in an oil refinery or chemical plant. There is a huge range of different chemicals and liquid that that stored and processed under pressure. These range from relatively benign substances such as milk and palm oil to crude oil and natural gas and their distillates to highly lethal acids and chemicals such as methyl isocyanate. So of these processes need the gas or liquid to be very hot, whilst others contain it at very low temperatures. As a result there is a wide variety of different pressure vessel steel grades that meet the different use cases.

In general these can be divided into three groups. There is a group of carbon steel pressure vessel grades. These are standard steels and can cope with many applications where there is low corrosion and low heat. As heat and corrosion have more effect on the steel plates chromium, molybdenum and nickel are added to provide additional resistance. The plates are collectively known as Chrome Moly steel plates. Finally as the % of chromium, nickel and molybdenum increase you have highly resistant stainless steel plates that are used in critical applications and where oxide contamination needs to be avoided – such in the food and pharmaceutical industries.

The manufacture of pressure vessels is tightly regulated as a result of the risks involved and as a consequence the materials that can be used in vessels is also tightly specified. The most common specifications for pressure vessel steels are the EN10028 standards – which are European in origin – and the the ASME/ASTM standards which are from the US.

Our strength is in the very high specification pressure vessel  steel plate used in the oil and gas industry and specifically in steel plate resistant to Hydrogen Induced Cracking (HIC) where we have one of the largest stocks worldwide.
