Liquefied Petroleum Gas Cylinder of Dry Filament Wound(DFW-LPG Cylinder)
DFW-LPG Cylinder
Composite filament wound products are usually made of resin and fiber, and the fiber bears the tension load along the direction of the fiber, then the resin is used for fixing the fiber and bear and transfer the shear load or the interlayer stress. There is no resin matrix in the composite structure of the DFW-LPG cylinder, so the shape of the product must be designed the shape of equal tension and use the geodesic winding. The fiber will only bear the tension load, the fiber will not slip or move even without the resin, that is the principle of dry filament winding.
The DFW-LPG cylinder is called the dry fiber reinforced composite gas cylinder with PE internal tanker, which is composed of the inner tanker, fiber, the protective elastic coating, the soft grip, the intelligent valve and the radio frequency identification.
The main production process of DFW-LPG gas cylinder is to make inner tanker blow molding, and make inner mold. After the inner liner of mold is finalized and wind with dry fiber around the mold, and finally the rubber coat is wrapped in the outer layer of the fiber.

Designing of DFW-LPG cylinder
Producing of DFW-LPG cylinder
    Different from foreign market, the quantity of liquefied gas used in China market is huge and the market of liquefied gas cylinder is complex. According to the current situation of domestic market, the project group designs smart valves and smart chips suitable for domestic market. The RFID chip is directly wound between the inner liner and the fiber layer so that it cannot be dismantled, which makes the dry fiber gas cylinder have the unique and permanent 'identity', at the same time, because destructive processes(such as removing rust, grinding, painting etc. ) to the valve does not need in the repair of appearance of the DFW-LPG cylinder. So the intelligent valve seat is embedded in the DFW-LPG cylinder, it is entangled into the inner layer of fiber and it cannot be dismantled, thoroughly solving the problem that the intelligent valve is easy to be cracked.

DFW-LPG cylinders must be approved by international quality system certification of ISO9000 and SGS and international product certification of DOT, TUV, UL, TC, CE and so on.

Advantages of DFW-LPG cylinder

At present, there are two kinds of cylinders: metal cylinders, traditional composite cylinders. The DFW-LPG cylinder has obvious advantages compared with the traditional cylinder.

It can be seen from the figure that the DFW-LPG cylinder has obvious advantages, and its comparative analysis is as follows:

In addition, the DFW-LPG gas cylinder has the following advantages:


Main application fields of LPG cylinder

Smelting of non-ferrous metal: Smelting of non-ferrous metal requires stable hot nature of fuel, no burning furnace products, non-polluting, and liquefied petroleum gas has these conditions. After the liquefied petroleum gas is heated, it can be conveniently introduced into the smelting furnace for combustion. Shandong Jinsheng Non-ferrous Metal Company has successfully applied LPG to the copper smelting process of Krupp smelting furnace in Germany, instead of the original gas combustion process, reducing the harm of impurities such as sulfur and phosphorus and improving the quality of copper.

Kiln roasting: All kinds of industrial furnaces and heating furnaces in China have always been mainly based on the burning of coal, which not only causes waste of energy, but also pollutes the environment seriously. To this end, the relevant departments put forward the task of China's future energy development: optimize the energy structure, establish a world-class clean, safe and efficient energy supply system, establish the promotion mechanism of the energy technology development and so on. In order to meet the requirements of this task, many industrial furnaces and heating furnaces use liquefied petroleum gas as fuel, for example, the liquefied petroleum gas is used for making ceramic tiles and baking sheet, which not only reduces the pollution to the air, but also greatly improves the quality of the products.

Automobile fuel: According to the announcement of China's urban environmental conditions in 2000, the quantity of cities exceeded the national secondary standards of air quality account for 63.5% of 338 cities monitored, cities exceeded the national third standards are 112 cities. China's air pollution has changed from industrial waste and coal smoke gas to photochemical smog, and the exhaust of automobile emission in large cities has become one of the main pollution sources of the atmosphere. At present, about 70% of urban air pollution sources come from automobile exhaust emissions. In order to solve this problem, since the end of twentieth century, China's major and middle cities have built a car filling station in succession, using liquefied petroleum gas instead of gasoline as automobile fuel. The change of the fuel variety has greatly purified the quality of the city's air and is also a major development direction of the utilization of LPG.

Resident's life: Liquefied petroleum gas (LPG) used by resident's life has mainly two ways of pipeline transportation and bottled supply. Pipeline transportation: the way of the pipeline transportation is mainly concentrated in the large and middle cities. It is used by the gas company of the city to mix the liquefied petroleum gas with the air, mix the liquefied petroleum gas with the gas or mix the liquefied petroleum gas with the air discharge by the chemical fertilizer. It is directly transported to the household by management. At present, many cities have realized this form of supply. Bottling supply: in the form of the bottled supply, LPG is distributed from the storage and distribution to each household by a sealed cylinder, which is used as a supply source for family cookers.

It originated in the early 1960s, and was first used in refineries and several industrial cities, and has been developed to rural villages. In the area of civil, there are more than 10000 LPG storage and distribution stations for gas cylinders, some of which have more than 2 on average.
