There are 3 following types of butt fusion welders to meet the standard ISO 21307 : 1. Single Low Pressure Fusion Jointing Welding Machines 2. Double low-pressure Fusion Welders 3. Sigle High Pressure Plastik Welding Equipment. As shown in the graphs of the various systems, the high pressure method of butt welding takes less time to make a weld than low pressure welding fusion. This is a very important factor in lowering the cost of installation, since the cycle times necessary for butt welding large diameter pipes are long. Using the high pressure poly welders means that daily productivity can be significantly increased. Here you can choose relevant SHP series high pressure hdpe welding machines from 40mm-1600mm.
Recently, the National Development and Reform Commission announced that at 24 o'clock on June 25, a new round of refined oil price adjustment window will open: each ton of gasoline and diesel are lowered by 55 yuan, of which 89 gasoline is lowered by 0.04 yuan per liter, and 92 gasoline is lowered by 0.04 per liter. Yuan, No. 95 gasoline is lowered by 0.05 yuan per liter, and No. 0 diesel is lowered by 0.05 yuan per liter. According to the general household car fuel tank 50L capacity estimate, adding a box of 92 gasoline will save about 2 yuan.
During the current round of refined oil price adjustment period (June 11-June 25), the price movements of London Brent and New York WTI crude oil futures showed a divergence. Among them, Brent oil price fluctuated and WTI oil price remained volatile at the current level. On average, the oil prices of the two cities fell slightly by 0.67% from the previous round of price adjustment. Affected by this, domestic oil prices will be lowered, and the retail prices of domestic gasoline and diesel will also be lowered.
After this price adjustment, since 2018, the domestic refined oil price adjustment has shown a pattern of “seven rises, four falls and one strandedâ€. As of this price adjustment, the price of gasoline has increased by 610 yuan per ton, and the price of diesel has increased by 585 yuan per ton.
