PRC reporter learned yesterday from the Municipal Quality Supervision Bureau, under the relevant provisions of the State Administration of Quality Supervision, from now on, our city will be the end of their shields with screws to connect the liquefied petroleum gas cylinders (referred to as "screw bottle" ) implementation of the discarded. It is understood that the use of liquefied petroleum gas cylinder is divided into two types, one is October 1, 1996 after the production, cylinder cover with the bottle attached by welding, "Welding of liquefied petroleum gas cylinder" or "welding bottle "; the other is October 1, 1996 prior to production, cylinder cover and the bottle with a screw to connect the liquefied petroleum gas cylinders, that is," screw bottle ", the number of nearly 2 million the city, accounting for the use of liquefied petroleum gas cylinders 65% of the total. According to "liquefied petroleum gas cylinders Periodic inspection and evaluation" requirement, the use of liquefied petroleum gas cylinder life span of 15 years, must be discarded after the expiration. Played this year on Sept. 30, 2011, October 1, 1996 before the production of "screw bottle" will reach 15 years of use period is extended to liquefied petroleum gas cylinders may appear sidewall corrosion, valve seal die down. Municipal Quality Supervision Bureau to remind the general public, "screw bottle" bottle body will be inspected and the deadline, after passing inspection within the validity period of the cylinder and can continue to use to expire. Beyond the time limit if the public can pay directly to cylinder cylinder test unit for scrap processing, you can first cylinder to the nearest filling station filling station to the cylinder by the test units in a retirement deal. Implementation of the scrap will be processed according to market the copper cylinder (iron) price depreciation charges. For example, a 15kg LPG could be filling the "screw bottle", the bottle of iron weighing about 15kg, the weight is 250g brass valve is about 1.25 yuan at current scrap iron / kg, copper (brass) 16.5 yuan / kg in the market prices, after deducting the implementation of the destructive handling charges, transportation management and production cost and so cost about 8 yuan, the final residual value of depreciation at 37 yuan.

本报讯记者昨天从市质监局获悉，根据 国家质检总局的有关规定，从现在开始，我市将对使用期限届满的护罩用螺丝连接的液化石油气瓶（简称“螺丝瓶”）实施报废处理。 据了解，目前市民使用的液化石油气瓶共分两种，一种是1996年10月1日以后生产，钢瓶护罩与瓶体经电焊连接的“焊接液化石油气瓶”，即“焊接瓶”；另一种是1996年10月1日以前生产，钢瓶护罩与瓶体用螺丝连接的 液化石油气瓶，即“螺丝瓶”，全市数量近200万只，占在用液化石油气瓶总量的 65％。 根据《液化石油气钢瓶定期检验与评定》的规定，液化石油气瓶的使用年限为15年，到 期后必须作报废处理。从今年起到2011年9月30日，1996年10月1日之前生产的“螺丝瓶”将达到15年的使用期限，超期的液化石油气瓶很可能会出现瓶壁腐蚀、阀门密封性减弱等问题。 市质监局提醒广大市民，“螺丝瓶”瓶体上会有检验合格期限，经检验合格且在有效期内的 气瓶可继续使用至期满。如果已超出期限，市民可直接将钢瓶交钢瓶检验单位作报废处理，也可以先将钢瓶交给就近的充装站，由充装站转交钢瓶检验单位实施报废处理。 实施报废处理的钢瓶将按照市场废铜（铁）价计算折旧费。举例说，一只可充装15ｋｇ 液化石油气的“螺丝瓶”，其瓶体铁的重量约15ｋｇ，阀门黄铜的重量为250ｇ左右，按目前废铁1．25元／斤、废铜（黄铜）16．5元／斤的市场价计算，再扣除实施破坏性处理费、运输管理工本费等费用约8元，最终 折旧残值在37元左右。（记者徐文燕通讯员吴婧） (本文来源：宁波晚报 ) netease
