通過(guò)在煉油廠的離心泵中多個(gè)耐磨部件的長(zhǎng)期性能驗(yàn)證，杜邦VESPEL CR-6100零件較近獲得了ISO13709和API610的官方認(rèn)可。在這兩個(gè)較新版本標(biāo)準(zhǔn)中，杜邦VESPEL CR-6100被列為泵靜部件的推薦材料。

杜邦的全球市場(chǎng)經(jīng)理Rene Garza說(shuō)：“我們堅(jiān)信，隨著杜邦VESPEL CR-6100正式列入ISO13709和API610標(biāo)準(zhǔn)，VESPEL CR-6100部件將會(huì)進(jìn)一步擴(kuò)大其在煉化和石化行業(yè)不同的泵中的應(yīng)用。目前全球有100多個(gè)煉化廠，超過(guò)5000臺(tái)泵正在使用杜邦VESPEL CR-6100制成的部件。成熟的應(yīng)用包括泵的口環(huán)，軸間襯套，滑動(dòng)軸承，減壓襯套等，主要用于輸送冷凝水，烯烴類(lèi)，酸水，液烴，汽油等其他難以輸送的介質(zhì)。工作的溫度范圍從-252°C到288°C。

據(jù)Garza說(shuō)明，VESPEL CR-6100能夠不斷獲得泵中應(yīng)用的主要原因就是它可以提高泵的性能，節(jié)約能耗和降低操作成本，并且可以減少泄露的發(fā)生。由于VESPEL CR-6100特殊的性能，相對(duì)于金屬口環(huán)等金屬摩擦副來(lái)說(shuō)，使用VESPEL CR-6100和金屬摩擦副后其設(shè)計(jì)間隙可以大大降低。更緊的運(yùn)行間隙可以提高泵的效率，節(jié)約能耗，大幅度降低震動(dòng)幅度，從而可以減少摩擦副的磨損量。通過(guò)多年的使用證明，當(dāng)出現(xiàn)異常情況，如干轉(zhuǎn)或者吸入壓力和流量不足時(shí)，VESPEL CR-6100零件仍然可以正常工作而不會(huì)出現(xiàn)意外停機(jī)和泄露等不良后果。另外，VESPEL CR-6100可能抵抗幾乎所有的化學(xué)介質(zhì)，包括胺和強(qiáng)酸。

Long valued for their performance in wear rings and other parts of centrifugal pumps at oil refineries, DuPont? Vespel? CR-6100 parts have recently gained recognition under the ISO 13709 International Standard and the American Petroleum Institute’s API 610 Standard.  The latest editions of both standards list PFA (perfluoroalkoxy) polymer reinforced with carbon fibers, the generic composition of DuPont? Vespel? CR-6100 parts, as a recommended material for stationary pump parts.

“We’re confident that the ISO 13709 and API 610 listings will result in even broader use of Vespel? CR-6100 for pump parts in refineries and petrochemical plants,” said Rene Garza, global marketing manager, energy and material handling – DuPont? Kalrez? and Vespel?.  Vespel? CR-6100 parts are working today in over 5,000 pumps at more than 100 refineries and petrochemical plants around the globe.  Proven applications include wear rings, line shaft bearings, bowl bearings, pressure-reducing bushings and throat bushings in pumps handling condensate, light hydrocarbons, sour water, gas liquids, gasoline and other aggressive fluids. Service conditions in actual installations range from cryogenic temperatures up to 288°C (550°F). 

Key factors in the growing use of Vespel? CR-6100 parts are that they enable improved pump performance, energy savings and lower operating costs, and can cut emission failures, according to Garza.  Thanks to their unique properties and attributes, Vespel? CR-6100 parts such as wear rings can operate with lower clearance than metal components.  Tighter clearances save energy by improving pump efficiency and sharply reducing vibration, thus cutting wear and tear on other pump components.  Vespel? CR-6100 parts have proven that they can reduce downtime and emission spikes by continuing to operate during process upsets that produce run-dry or low-flow conditions.  In addition, they are highly resistant to most chemicals, including amines and strong acids.
