International oil prices fell in three places

At the end of February 2013, the price of domestic refined oil was raised , and the price of gasoline was increased by 300 yuan per ton, and the price of diesel was increased by 290 yuan per ton. The domestic prices of main gasoline and diesel oil all surged. However, due to strong domestic expectations before the price adjustment, strong diesel demand, digest some gains, so the diesel gains are relatively reduced, the actual increase in most areas is only about 150 yuan / ton.

Analysts of refined oil products said that as the good news of price adjustments dissipated, the domestic refined oil market sentiment turned sharply. The mid-to-downstream customers had high stocks, all consuming the current stocks, and there was no interest in purchasing. Therefore, the market turnover was sluggish, and the main sales were low. It was light, there was no market for prices, and late last week, prices in some regions were unable to support a decline. Coupled with the recent upward resistance of crude oil, the industry has a strong wait-and-see attitude and careful operation, so the overall market is showing signs of fatigue.

In addition, on the international market, the European and US economic indicators are uneven, the dollar oscillates upwards, and Italy’s political instability and other factors, crude oil futures prices showed a downward trend.

In recent days, the international oil price trend has dropped, and the rate of change in crude oil in the three places has been suppressed. On March 1, the rate of change in crude oil has fallen from rising to falling. As of the close of February 28, Zhongyu Information estimated that the rate of change in crude oil in the three places was 0.01%, down by 0.07% from the previous day. The rate of change in the three places will be turned from negative to positive. According to the current spot price of crude oil, the rate of change in the three places will fall to a negative value on the next working day. The international crude oil prices fell in the past few days and the domestic crude oil settlement price was lower than that of the previous month. The bearish sentiment was strong in the market. At the beginning of the month, the sales pressure on the main markets across the country was relatively high, and preferential policies were introduced in some markets such as East China, Yanjiang, and North China to seize market share.

Analysts said that after the National Development and Reform Commission raised the price of oil, the local market further pushed up the price, but due to the end of the actual demand of the terminal is relatively flat, and the demand for stocks tended to be saturated, the turnover of the main new orders weakened, and thus the short-term market conditions are expected to continue to fade. , The industry more than digest the pre-inventory-based unintentional purchase, the main price pressure is expected to continue dropping.

As of March 1st, the average price of gasoline and diesel oil sold by PetroChina and Sinopec's sales companies in 26 major cities monitored by certain information was: 9850 yuan/ton of 93# gasoline, which was 5 yuan/ton lower than the previous working day; 0# diesel 8528 RMB/ton, which has fallen by RMB 4/ton over the previous working day. At present, the market price of gasoline and diesel is 447 and 344 yuan/ton more than the average retail price. Compared with the price adjustment, gasoline and diesel prices rose by Rmb303/tonne and Rmb84/tonne respectively, but fell by Rmb14/tonne and Rmb21/tonne on the first day of the adjustment (February 25).

Analysts believe that the international crude oil and market demand are all negatively short-term domestic oil market fundamentals, after the price increase, the market will have 1-2 weeks to inventory period, and the market outlook is pessimistic, in early March the market will be difficult to get rid of wilting Quotes; In the middle or late March of the year, the market may be reversed due to the refinery inspections and boosting oil demand for spring ploughing. March is the transition period of gasoline and diesel, the market fluctuations with the international crude oil changes relatively fast, the international crude oil trend is uncertain, the three areas of the rate of change in a negative downward trend, but the market demand in March is in the recovery period, some of the main refinery plant overhaul, As a result, the market resources are reduced, the bad game is favorable, and the market trend is difficult to determine. It is suggested that the industry can still purchase on demand.

Excavator cylinder oil seals

â‘ Hardness:

Due to the scientific synthesis of high-molecular polyurethane elastomer materials using iron rubber, the higher the hardness, the higher the modulus, the smaller the elongation, and the better the wear resistance and heat resistance. Well, in the range of minus 35 degrees Celsius to 100 degrees Celsius, and at a pressure of 60 to 70 MPa, the maximum sealing performance can be guaranteed.

â‘¡Pressure resistance:

The use of viscoelastic seals made of nitrile rubber is the most complete protection against damage caused by back pressure. In the range of minus 55 degrees Celsius to 100 degrees Celsius, and under a pressure of 21MPa, due to the rubber The seal is often in a compressed state, so the compression performance of the rubber seal must be considered. It not only achieves enhanced anti-climbing performance and low friction resistance, but also has good performance in dealing with special low-temperature oil, and can also be used in combination with Anti-wear Ring double-purpose retaining ring BRL type.

â‘¢Prevention of oil leakage:

Sealing products made of polytetrafluoroethylene and nitrile rubber/PTFErubber; or seals made of nylon resin and nitrile rubber, which can be used in a wide range of applications with large pressure changes and fast sliding speeds According to the working condition, the input hydraulic pressure cutout is designed on the end face of the polytetrafluoroethylene ring to prevent penetration leakage. The maximum working temperature environment is minus 40 degrees Celsius to 160 degrees Celsius; the maximum working pressure is 50MPa.
