JIS" Stands for Japanese Industrial Standard and are published by the Japanese Standards Association (JSA) which is the equivalent of ANSI in the United States. They are created and updated by the Committee of the Japanese Industrial Standards (JISC). Like JSA to ANSI, the JISC is similar to the American Society of Mechanical Engineers (ASME).
Japan Industrial Standard is yet another option for metric sizes. Provided in JIS5K, JIS10K, JIS15K, and JISK20K pressure classes, we can offer Slip On, Blind, and Weld Neck varieties in Raised Face or Flat Face configurations. These are typically made of 316/L or A105, but as usual, all alloys are available!
Much like DIN / metric flanges, the JIS Flange specification offers a slightly wider variety of slip weld configurations for the purposes of space limitations and suitability for existing pipeline equipment. For instance, a customer can request a slip on with or without a hub as standard, or even a ring type flange, and all of this within the same B2220 specification.
JIS flanges are commonly found in exported pressure equipment and pipe assemblies from Japan. Many large ships and sea vessels which travel through international waters and service the Pacific rim will utilize equipment made to this standard, as parts and servicing for this specification are widely available.

Features First, influenced by the country's four policy <br> <br> data show that in June 2013, the country's heavy truck (including non-complete vehicles, semi-trailer tractor) production of 59,000, an increase of 51.70%; sales 75100 Vehicles, an increase of 50.82% over the same period last year. The "explosive" performance that exceeded expectations in June has a lot to do with the expectations of major truck manufacturers and distributors on the implementation of the National IV emission standards on July 1. According to the requirements of the Ministry of Environmental Protection, new national heavy-duty trucks will no longer be allowed to be sold on July 1, 2013. Based on this policy expectation, some manufacturers and regional distributors have adopted advanced billing methods to evade July 1st Four new regulations marketing strategy.
Driven by this kind of “overdraft consumptionâ€, the heavy-duty truck market sales situation in June was excellent. However, in the monetary policy tightening, the physical economy is weak, the manufacturing downturn and other factors, "early overdraft" sales brought about by the "good days" or difficult to continue, the second half of the heavy truck market is still hidden. As the wait-and-see sentiment caused by the implementation of the uncertainty of the national IV emission standards caused a negative drag on sales in July, the sales growth of heavy trucks in July declined compared with the previous two months, and fell to around 25%.
In 2014, we will expand the implementation areas of the four heavy-duty commercial vehicle country emission standards. Henan, Shanxi, and Fujian will implement the four-card discharge standard on January 1, 2014, and Hubei, Guangdong, Hebei, and other places are also brewing and promoting the national quadruple-duty card. . At present, China National Heavy Duty Truck and other heavy truck manufacturers in the relevant regions of the dealers, is stepping up the country's triple card inventory, each car to reduce 10,000 yuan to 20,000 yuan ranging from promotions. From the heavy truck dealerships in several brands in Henan and Shanxi, it is understood that distributors are currently stepping up promotional efforts to handle the nation’s triple card inventory before New Year’s Day.
China National Heavy Duty Truck dealers in Henan said that at present, the company’s national triple card still has more inventory, and the national quadruple card and the national triple card each account for half of the sales. The current sales of the national triple card, according to different models, the promotion range of 10,000 yuan to 20,000 yuan range. Futian Automobile dealers in Shanxi said that at present, the region has also begun to cut prices to deal with the country's triple card, bicycle prices cut about 10,000 yuan.
The dealer said that near the end of the year, coupled with the implementation of the national quadruple heavy truck in 2014, the national triple card could not be on the road, and sales personnel all hope to handle the national triple card inventory as soon as possible. A distributor of Shaanxi Heavy Duty Truck Co., Ltd. stated that although all localities have already strictly enforced the implementation of the National IV emission standards, it does not mean that the national triple-duty truck will have no sales in 2014. At present, the phenomenon of not registering license plates for heavy trucks is relatively common in some regions. Although the national triple card cannot be used on the road, it does not affect the sales of heavy trucks in open-pit mines and other areas that do not need to be on the road.
Second, the characteristics of natural gas heavy truck usher in development opportunities <br> <br> Recently, the haze has been a hot topic. According to the data from the China Meteorological Administration, since 2013, the average number of haze days in the country has been the highest in 52 years, and Anhui, Hunan, Hubei, Zhejiang, and Jiangsu have all recorded “historical records†in 13 places, and 104 cities have been heavily polluted. According to the report of the environmental protection department, it can be found that the cause of haze is on the one hand the climatic cause, that is, the climatic conditions are not conducive to the diffusion of pollutants, and on the other hand, a large number of pollution discharges are continuous. Although climate is an external cause, internal factors are the decisive factor in the case where pollution emissions are difficult to reduce immediately.
Through detailed analysis, the high energy consumption and high emission transportation industry has become the focus of pollution incidents. Among these, trucks, as high-energy transportation vehicles, account for an average of nearly 65% ​​of the country's gasoline and diesel consumption each year. Against this background, as the best tool for energy saving and emission reduction in the commercial vehicle sector, the mission of natural gas heavy trucks to save energy and reduce emissions and reduce pollution and consumption has long been widely used in the market. In 2013, Shaanxi Automobile's natural gas heavy truck sales exceeded 10,000 vehicles.
As we all know, the three elements of high energy consumption, high pollution, and resource are bound to be the contradictions that must be resolved and coordinated in the construction of a "beautiful China" system project. Road transport has become the focus of this contradiction. Among these, logistics transportation based on trucks has become the core of this contradiction. Trucks that consume large amounts of gasoline and diesel will also face energy crisis. Compared with diesel vehicles, the advantages of natural car trucks in economy and environmental protection are significant.
As far as environmental protection is concerned, diesel vehicles are almost the source of particulate emissions in the entire transportation sector. In addition to PM, there are NOx (nitrogen oxide), SOx (sulfur oxide) emissions. Natural gas, especially LNG (liquefied natural gas), has a very low sulfur content, and an average of 6 tons of LNG can reduce the emission of SOx per ton.
According to the current domestic truck height road transport consumption of the standard, about 40L/100km; under the same conditions, using LNG as fuel is about 70L/100km, which greatly reduces the emission of nitrogen oxides, sulfur oxides and particulate matter. Against this background, how will trucks, one of the necessary tools for highway logistics and transportation, play their role in the future and contribute to the goal of "beautiful China"? Promoting natural gas trucks may be the best answer at this stage.
Three characteristics, force manufacturers to high-end models <br> <br> with the fierce competition in the domestic logistics market, logistics and transport operators to intensive development, vehicle operating costs rising, how to improve transport efficiency and reduce logistics costs, as The tool for making money—trucks—has gradually shifted from a low-end economy to a mid-to-high-end market. Such a product can not only meet the requirements of energy conservation and environmental protection, but also reduce the use efficiency of increased vehicle costs. Therefore, high-end heavy trucks are often more cost-effective in terms of overall cost of use, lower cost, energy saving, and environmental protection.
