Singapore, China get US waiver on Iran oil sanctions the effect for the stainless steel pipe fitting

时间：2020-01-05

The US said China and Singapore have “significantly reduced” their purchases of Iranian oil, earning exemptions from US financial sanctions that otherwise would have been imposed Thursday. China was the biggest importer of Iranian crude last year, and Singapore is Asia’s oil trading and refining hub. The US granted renewable, 180-day exemptions on March 20 to Japan and 10 European Union nations. India, South Korea, Turkey, South Africa, Malaysia, Sri Lanka and Taiwan won exemptions June 11. “A total of 20 world economies have now qualified for such an exception,” Secretary of State Hillary Clinton said on Thursday in an e-mailed statement. “Their cumulative actions are a clear demonstration to Iran’s government that Iran’s continued violation of its international nuclear obligations carries an enormous economic cost.” China made substantial reductions in imports in the past six months because of a pricing dispute with Iran early in the year. It has pledged future cuts, according to a US official who spoke on condition of anonymity before the announcement. “China has been importing crude oil from Iran through normal channels based on its economic development needs,” Hong Lei, a spokesman for the foreign ministry, said on Friday in Beijing. The purchases are “completely justified and legitimate,” he said.

304不锈钢板应用于螺旋风管
螺旋风管这是按其用途定下的名称，但它又可用于其它地方，甚至用来排水，排液体或作容器，这就不能叫它风管。按构造来命名，应管它叫螺旋咬缝薄壁管，由于主要用金属做的又管它叫螺旋咬缝金属管。如果按材料归类命名，大概可有这几个名：镀锌（铁）螺旋管、不锈钢螺旋管、铝螺旋管，或为了区别于现有不锈钢管，可管它叫**薄不锈钢管，因它可用0.3毫米甚至更薄的不锈钢带卷制而成。用途：螺旋风管是用金属带料卷制成螺旋形咬缝
管螺纹基础知识
管螺纹：主要用来进行管道的连接，使其内外螺纹的配合紧密，有直管和锥管两种。英制管螺纹来源于英制惠氏螺纹，惠氏螺纹的管路系列与惠氏螺纹牙型组合建立起了英制管螺纹的基本尺寸.按1/16锥度关系，惠氏螺纹的径向直径公差转化为英制密封管螺纹的轴向牙数公差（存在一定量的修约和调整）.再参照英制密封管螺纹的公差值提出英制非密封管螺纹的公差（公差由单向分布变为单向分布，放松**径公差，放开底径公差）.三种螺纹提
