Pressure vessel and boiler quality steel are commonly found throughout the oil industry (including inshore and offshore), the petrochemical industry and the gas production industry. The companies in these industries set the highest demands in terms of quality, testing and conditions of supply, and we have all the necessary expertise to meet these demands.
In recognition of the increasing need for pressure vessel Steel Plate to demonstrate HIC Resistant properties. Our product is also particularly suited for pressure equipment where wet H2S corrosion can be a problem.
Pressure vessel steel plate covers a range of steel grades that are designed for use in pressure vessel, boilers, heat exchanges 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 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).

Lighting and backlight modules support the overall LED market demand, but as LEDs grow slower after the penetration rate of liquid-electric backlight modules reaches 95, only LED lighting will remain in the future, so LED manufacturers are actively developing new applications. I hope to use the high-margin, diversified niche market to support new applications and drive the demand for another wave of LEDs.
Huang Denghui, general manager of layout plant lighting Lunda pointed out that Zonglongda’s revenue is still dominated by backlight modules, with a proportion of 60%. As for lighting, the overall LED in the lighting market is rising, accounting for the proportion of revenue. Climbing, the current lighting accounted for about 30% of revenue.
According to market research firm LEDinside, the overall LED lighting market value in 2014 was 35.3 billion US dollars, up 47.8 compared with 2013. In 2014, the LED lighting penetration rate will also increase to 32.7, of which the bulb and lamp penetration rate will reach 20 respectively. With 15.
In addition to the lighting market, in fact, Ronda is also actively developing new applications such as automotive, plant lighting, UV (ultraviolet) and medical, etc. Only this part of the market has just begun, the amount will not be very Big. However, Huang Denghui said that the LED-related new market is small and the number of investors is small. Although it is a niche market, the gross profit is quite high. Ronda is conducting research and development, so it cannot make an immediate contribution to revenue.
Mobile phone application shipments increased. He said that after the Chinese New Year, the overall market demand has increased significantly, and the current market inventory has been emptied. Therefore, the overall production capacity has been tight, and Ronda’s capacity utilization rate has increased to over 80% in March.
With the arrival of the peak season in the second season, including lighting demand, the package is also tight. In particular, smartphone applications continue to be shipped to mainland China and Japan's first-line mobile phone brands. Currently, shipments of mobile application products are expected to reach 70 million in April.
Editor's point of view: LED backlight market has become saturated, and LED lighting penetration rate is also rising rapidly. In most LED factories, or in the LED lighting market, the LED niche market has attracted industry attention, such as plant lighting, UV LEDs for medical applications, automotive LED lights, etc. The niche market will become the new blue ocean of the LED industry.
