imbedded and exported from concrete base, filling in pipes hole with sand in case of diffusion of vapor. Delivery pipe in concrete should be a little higher, connected with corrugated pipe through flange and oil-resistant gasket. (See Diagram 5-2) Installation of pipeline and tank 3.1 The set of design of tank and pipeline should be conducted by locale design agency that has acquired ratification of public safety and firefight department with qualified capacity. In order to ensure system safety, filling station should not self –design pipeline of delivery oil. Diagram 5-3 is a pipeline installation sketch map of fuel dispensers and hydraulic system, which is provided for reference. The design and construction of filling station should conduct in accordance with the relevant stipulation of national standard GB 50156-2002 The Design and construction regulations of v fuel dispenser ehicle LP-Gas Station. Diagram 5-2: Connection chart of inlet pipe and corrugated pipe 3.2 Pipeline between fuel dispensers and tank should be slant to tank. In hot whether pipeline slope regulated as 0.2% in GB50156 is easy to generate cavitation. Foreign fuel dispenser factories regulate larger slant such as Gilbarco 10ft (about 1.67%), Wayne 1:48 (2%). Thereby, it is suggested that the slant should be in scope of 1.5~~~ 2%. Diagram 5-3 Pipeline installation sketch map 3.3 Gasoline and diesel oil tank should be burred in earth under ground at least 0.5m , prohibiting in indoor or basement. Tank should not be burred in the earth in which includes coal residue or chemicals, and surrounded by non-erosive material such as sand or thin earth, thickness no less than 0.3m. 3.4 The level distance be fuel dispenser tween fuel dispenser and tank should be 20m or more as long oil could be suck without any leakage. The vertical distance between the inlet of fuel dispense and the nadir of oil level should not exceed 4m. The diameter of pipe between fuel dispenser and tank is 38m (1 1/2’�, which keeps clean with few elbows. The connection of delivery pipes fuel dispenser

pital and established a start-up in 1993. His initial hot-air balloon strategy failed, however. Then flyaway balloons caught his eye. Show Corporation now has 16 employees in Japan and 71 in China, where it has based production, and it has cornered the market for large, inflatable character balloons in Japan. At the closing ceremony of the 2002 World Cup in Yokohama, Mr Nishi inflated a balloon 20 metres high in the shape of Mount Fuji in one minute using 25 fans, having beaten more than 250 rival companies for the contract. Show also rents vehicles made out of balloons to Disney World in Florida. They are popular with grandparents accompanying children. The firm s biggest source of profit now is an environmentally friendly design of balloon. Traditional flyaway rubber balloons were under attack from environmentalists and quickly losing their popularity. fuel dispenser Show invented a new type from Japan s traditional, delicate mulberry-bark paper. The firm s reputation was made with events such as the 1998 Winter Olympics, which took place in Nagano, when its dove- shaped balloons were released to prevent live birds being singed by the Olympic flame. Recently (to purists dismay), Show switched to cheaper rubber balloons that dissolve after exposure to ultra-violet rays. It sells about 200,000 to 500,000 of these every month in Japan, and is expanding its market overseas, from Britain to Dubai. Now Mr Nishi is inundated with requests for balloons that can be used in industry. The company has developed an inflatable cushion to break the falls of workers who clean high ceilings. Having found that most deaths in the tsunami that hit Indonesia in 2004 were caus fuel dispenser ed by bodies being hurled against hard things, rather than drowning, Mr Nishi also makes inflatable life jackets that protect the vertebrae from up to 200kg (440lb) of weight. Show s success has brought more private investors, a change from the early days, when 50 banks turned it down for a loan. Mr Nishi continues to build his fortune on air. fuel dispenser
