Asia's para-xylene market supply gap large This report, the British PCI consulting company has said that this year, Asia's net imports of paraxylene (PX) will increase by 350,000 tons over the previous year, reaching 1.3 million tons, mainly due to pure benzene The increased capacity of formic acid (PTA) has exceeded PX's expanded capacity. PTA's capacity is expected to increase from 13.7 million tons last year to 19 million to 20 million tons in 2009. China will be the largest importer of PX, and the PX market gap in 2007 is expected to soar to 2.4 million tons. The company said that this year's PX exports from the United States are expected to increase to 1.7 million tons. U.S. PX manufacturers oscillated between the production of PX and the production of gasoline. After the production of 685,000 tons/year of Taiwan Formosa Chemical Fibre Co., Ltd. was started and put into production in 2006, Taiwan's PX imports in 2007 will decline to 1.3 million tons. After the start of the new Iranian PX plant, its PX exports to the Asian market are expected to reach 800,000 tons in 2007. Iran’s two new PX plants with a total capacity of 1.1 million tons/year will be put into operation next year, so the operating rate of PX plants will remain at 89% in the next three years. Since the construction period of the new PX device needs at least 3 to 4 years, it is difficult to predict the supply and demand of PX more accurately for several years. The next round of cyclical investment is expected to be carried out by companies that can obtain important raw materials such as naphtha or reformed xylene.
Across the pond, you will find the Deutsches Institute fur Normung (DIN) flange specification, consisting of a variety of European styles which have been unified into one code for the purpose of commonality. Designation as a Din Flange by the German Institute of Standardization assures the user of design quality the way an ASME flange would here in America. Although much less common than ANSI/ASME Steel Flanges in the United States, many of our international customers request flanges to these specifications for a variety of applications such as imported steel vessels, cargo ships, and other infrastructure which may consist of metric pipes/valves and European designed equipment.
The subset flanges under the DIN standard consist of the same style of flanges in the United States, including the most commonly used slip on flanges, weld neck, flanges, and Blind Flanges. Adapter flanges can be custom made to end user requirements for the mating of American flanges to international ones, however we find it is a much more common and easy solution to provide DIN flanges to mate to existing equipment.
The most common metric type flanges fall under the following categories:
DIN 2501 through 2503 for flat ring flanges
DIN 2512 through 2519 for alternate face flanges
DIN 2627 through 2633 for weld neck flanges
DIN 2641 through 2642 for lap joint flanges
DIN 2565 through 2569 for threaded/companion flanges
DIN 2527 for blind flanges
