After the domestic retail price of refined oil remained at a standstill for up to four months, Sinopec (600688, 00386), chairman of Shanghai SINOPEC (600688), requested the price adjustment and caused the industry to raise the price of refined oil products again. This kind of argument.

During the two sessions, Shuguang Road stated that "it is expected that the Chinese government will soon increase the price of refined oil. If the price of refined oil is not raised in March or April, the operation of the company will be affected. The price of refined oil should be raised by 700 yuan per ton to ensure normal Profit rate."

Shuguangdao is not the first person in the refining and chemical industry who said that the refining industry is in difficulty during the two sessions. Yu Xizhi, general manager of the Sinopec Anqing branch and the NPC deputy, said on the 7th that “at present, the price of crude oil for domestic refined oil prices is slightly higher than US$70 per barrel. The current pricing mechanism has lowered Sinopec’s refining margins.” Jinling Petrochemical chairman and National People’s Congress representative Zhang Dafu said on the 8th that, despite the reform of oil pricing last year, Jinling’s refining profit margin has been negative since July of last year. After the last adjustment in November last year, domestic fuel prices were equivalent to about US$67 a barrel of crude oil.

China's latest increase in refined oil prices on November 10 last year, gasoline and diesel prices increased by 480 yuan per ton per ton, after the maximum price has not changed.

According to the refined oil pricing mechanism introduced at the beginning of 2009, the average daily oil price of international oil prices has fallen by more than 4% for 22 consecutive working days. It is therefore necessary to consider adjusting domestic refined oil prices. One of the objectives is to ensure that refineries have a reasonable profit margin.

This was originally a program that can largely balance the interest relationship between oil companies and consumer groups. It is also a major step forward in the reform of the marketization of refined oil prices in China. However, at present, the domestic refined oil price has been raised five times last year. , 3 times, actually did not satisfy the parties.

The mechanism for the price adjustment of refined oil in China has been introduced and is in operation, but the criteria for price adjustment brought about by this mechanism have not been transparent. Perhaps the oil refining company is very wronged, "obviously they have lost or will lose money," the price adjustment has not yet been put in place; perhaps the consumer groups believe that the price adjustment is often "chasing does not recover", "the refinery is obviously making money but have to say that they have to lose ".

The Chairman of Sinopec Corp. clearly specified the approximate time period and price adjustment range of oil price adjustment. It expressed its own position and there was no doubt about it. The deputies to the National People's Congress were to represent the interests of some people and groups, but they were crying out that their operations would "At the same time as being affected," we need to come up with data that people can read, and not just suggest that the government make a "result" of price adjustment.

Some analysts told the China Securities Journal that “If the domestic oil refinery’s $80 oil price is not adjusted, there is still no problem with refinery operations and it is still profitable. Calculated at the ex-factory price, there are still Oman crude oils processed in coastal areas. 300-400 yuan profit."

As of yesterday, the monitoring of domestic commodity information service providers showed that the Brent/Dubai/Xinta weighted average price change rate was 0.18% over 20 working days. If the number of monitoring data from this agency is not far from 4% Red line.

Intuitively, due to the lack of information transparency, the statement made by the oil refinery companies does not correspond to the data of the third-party organizations. In fact, it has caused the consumer groups to fall into a confusion of understanding. This confusion has brought many questions and dissatisfaction.

Industry sources said that all parties are dissatisfied with the price adjustment, and not too much doubt about the mechanism. The refinery suffered losses and took the data to speak. Upgrading oil prices is believed to have no opinion. The problem now is that the mechanism needs to increase transparency, not just shorten the "22 workdays, 4%" standard again.

A Heat Exchanger is a device designed to efficiently transfer or "exchange" heat from one matter to another. When a fluid is used to transfer heat, the fluid could be a liquid, such as water or oil, or could be moving air. The most well known type of heat exchanger is a car radiator. In a radiator, a solution of water and ethylene glycol, also known as antifreeze, transfers heat from the engine to the radiator and then from the radiator to the ambient air flowing through it. This process helps to keep a car's engine from overheating. Similarly, our heat exchangers are designed to remove excess heat from aircraft engines, optics, x-ray tubes, lasers, power supplies, military equipment, and many other types of equipment that require cooling beyond what air-cooled heat sinks can provide.

There are various types of heat exchangers. our heat exchangers provide air-to-liquid cooling, liquid-to-air cooling, liquid-to-liquid cooling, or air-to-air cooling. With air-to-liquid cooling, heat is transferred from the air to a liquid. One example of air-to-liquid cooling is cabinet cooling. With liquid-to-air cooling, the heat is transferred from the liquid to the air. This type of cooling is generally used to cool process fluids. Liquid-to-liquid cooling is also used to cool process fluids, but the heat is removed by another liquid instead of by air. Lastly, with air-to-air cooling, heat is transferred from one air or gas stream to another.

we has been manufacturing one of the most widely used heat exchanger technologies, tube and fin heat exchangers, for more than 20 years. Tube and fin heat exchangers provide air-to-liquid cooling or liquid-to-air cooling. They consist of fin, hairpin tubes, return bends to connect the hairpins, a tube sheet to support and properly align the tubes, a header with inlets and outlets, side plates for structural support, and usually a fan plate. The tubes provide the path for the liquid coolant, and the fin adds surface area for more heat convection. Copper is often selected for tube and fin material due to its excellent thermal conductivity and compatibility with water and ethylene glycol solutions. However, stainless steel is used for tube and fin when it's necessary for the coolant to be deionized water or other corrosive fluids.

ourо oil cooler flat tube heat exchangers also have tubes and fin; however, the tubes are flat instead of round. This helps to minimize pressure drop when oil or ethylene glycol is used as the coolant. The surface area of the flat tubes is also much greater than the surface area of the tubes in a tube and fin heat exchanger. The additional surface area of the tubes in an oil cooler flat tube heat exchanger maximizes heat transfer when poor heat transfer fluids like oil or ethylene glycol are used. These oil cooler heat exchangers consist of fin, flat tubes, a welded header with inlets and outlets, and plates, including an optional fan plate.

Another type of heat exchanger is a plate-fin heat exchanger, which can provide air-to-air, air-to-liquid, liquid-to-air, or liquid-to-liquid cooling. Plate-fin heat exchangers consist of finned chambers separated by flat plates and are circuited in alternating hot and cold fluid passages. Heat is transferred via fins in the passageways, through the separator plate, and into the cold fluid via the separator plate, and into the cold fluid via fin once again. The heat exchanger also has manifold ducting, mounting brackets, and a frame.
