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

時(shí)間：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不銹鋼管件表面處理常見(jiàn)問(wèn)題-臨沂三威精密鑄造有限公司
304不銹鋼管件表面著色處理：一、表面本色白化處理：不銹鋼在加工過(guò)程中，經(jīng)過(guò)卷板、扎邊、焊接或者經(jīng)過(guò)人工表面火烤加溫處理，產(chǎn)生黑色氧化皮。這種堅(jiān)硬的灰黑色氧化皮主要是NiCr2O4和NiF二種EO4成分，以**般采用氫氟酸和硝酸進(jìn)行強(qiáng)腐蝕方法去除。但這種方法成本大，污染環(huán)境，對(duì)人體有害，腐蝕性較大，逐漸被淘汰。目前對(duì)氧化皮處理方法主要有二種： ⑴噴砂（丸）法：主要是采用噴微玻璃珠的方法，除去表面
