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).

From the point of view of the petroleum and chemical equipment manufacturing industry, following the good trend of the previous years, the industry's operating performance in 2006, such as industrial added value, sales revenue, profits, and exports, has maintained a rapid growth of over 40%. At the same time, the industry has also made important progress in independent innovation, localization, upgrading and adjustment of product structure, and industrial clusters. The three major petroleum and chemical equipments identified by the Central Government have achieved encouraging results in 2006: Offshore oil and gas projects are equipped with 9,000-meter oil drilling rigs, 300,000-ton floating production and storage tankers, and 300,000 tons of giant oil tankers, etc. ; million tons of ethylene has 640,000 tons / year ethylene cracker compressor, 300,000 tons / year polypropylene loop reactor and 720,000 tons / year ethylene cold box, one million tons of PTA project has a full set of process software packages Successfully developed; coal chemical equipment is equipped with 60,000 air separation, 2,000 tons of coal liquefaction reactors, and the promotion and application of various advanced technology gasifiers.
There is a problem
According to Cai Weici, there is no shortage of hidden dangers in the rapid development of the machinery industry: the revitalization of the main body is weak and unsteady; the growth pattern is not fast; the ability of independent innovation cannot meet the needs of structural upgrading; the bottleneck of the supply of major raw materials is becoming increasingly prominent. In short, the continuous development of the industry's ability to resist risks is still very fragile.
In the oil and chemical equipment manufacturing industry, the level of intelligence and quality of China's oil drilling rigs have yet to be improved. The variety of drilling rigs is relatively single and lacks the design and production capabilities of special drilling rigs. The overall technological level of geophysical exploration and logging equipment is far from the foreign products. There is no competitive advantage in the international market; from the perspective of petrochemical equipment, there is a lack of continuous innovation and the general petrochemical special equipment manufacturing capacity is surplus, while major equipment manufacturing capacity is insufficient. In terms of the industry as a whole, companies generally have weak R&D capabilities, low technical standards, lack of core technologies and high-quality products with independent intellectual property rights, lack of independent innovation capability, disparate research resources, lack of overall planning, and large numbers of companies and small scale enterprises. Respectively, the phenomenon of low-level redundant construction is serious, resulting in a waste of production capacity and a certain degree of disorderly competition in the industry.
In terms of imports and exports, according to Zheng Guowei, director of the Import Office of the former Ministry of Machinery Industry, despite the rapid growth in exports of petrochemical machinery products in China and the gradual increase in surplus in 2006, the situation is very good, but at the same time it should be noted that the current import and export of petrochemical machinery products in China The structure is still not ideal, the proportion of exports of self-owned brands and high-tech products is low, and the proportion of key components, technologies, and technologies for importing major equipment is low.
To this end, the industry must not only continuously update industrial equipment in accordance with current production needs, but also focus on the long-term and make up its mind to strengthen the construction of R&D means, R&D capabilities, and R&D conditions. Not only should we focus on the introduction of technology and talents, we must also be determined to nurture our own core technologies, R&D talents and high-tech talents. Only in this way can our development be based on sustainable development. Our ability to resist risks can have a certain degree of autonomy in today’s international competition.
2007 Outlook
According to Cai Weici, in 2007 the total output value of the industrial machinery industry, industrial added value, and main business income will increase by about 20% from 2006, total profit will increase by about 20%, and total imports and exports will increase by about 20%. For the petrochemical equipment manufacturing industry, according to the prediction of the China Petroleum and Petrochemical Equipment Industry Association, 2007 will be an uncertain year. On the one hand, the world’s oil prices will still change substantially. Even though the current oil price has fallen sharply, the oil As a non-renewable energy source, the general trend of its price rise will not change, and it will be greatly affected by political factors, natural factors and economic factors. On the other hand, China's petrochemical equipment, especially oil drilling equipment, has experienced rapid growth in exports, and most of the export areas are developed countries and regions such as the United States and Canada. Many enterprises’ products are mainly exported, domestic demand is relatively weak, and industries and enterprises are relatively weak. The development of China depends more on the international market, which adds to many uncertainties.
According to the impact of the continuous drop in oil prices since August 2006, so far, the drop in oil prices has not had much impact on the oil drilling equipment industry. The major economic indicators continue to grow rapidly. The number of companies and total investment remains In constant growth. The refining and chemical equipment manufacturing industry is relatively sensitive. Since September 2006, there have been two consecutive losses in loss-making enterprises and total loss. The growth of major economic indicators has slowed down significantly. In 2007, the growth rate of the oil drilling equipment industry is expected to remain at this year's level, that is, the total industrial output value and product sales revenue will increase by more than 65%; the growth of the refining and chemical equipment industry will tend to slow down, and the total industrial output value and products The increase in sales revenue is between 25% and 30%; the increase in pressure vessels is relatively small at around 20%. The growth rate of the whole industry in 2007 could reach approximately 38% to 40%.
2006 was the first year of the “Eleventh Five-Year Plan†and also the first year of the promulgation and implementation of the strategy for the revitalization of the equipment manufacturing industry in China. It has the epoch-making significance of inheriting the past and the future. According to Cai Weici, vice president of the Federation of Machinery Industry, the economic performance of the entire industry in 2006 was relatively good, showing six characteristics: First, the industry's operating speed rebounded sharply and returned to the high-speed area; second, the overall quality of operations. Better, economic growth is faster than growth in production and sales; Third, rapid growth in key industries, industrial structure trends are encouraging; Fourth, industrial structure continues to optimize progress, technological progress continues to make progress; Fifth, export growth is higher than imports, trade deficit Rapid reduction; Sixth, investment growth tends to drop at a high level, and capacity expansion remains strong.
