AC-1鋁合金用犧牲陽極

AC-1 aluminum alloy sacrifice anode

我們提供的鋁陽極能夠防止海水中鋼質(zhì)結(jié)構(gòu)的腐蝕，廣泛應(yīng)用于 船體、 壓水艙、海水管道、港口碼頭設(shè)施、海洋工程、鉆井平臺(tái)、冷凝器以及土壤介質(zhì)的管道等的防腐之用。鋁陽極的性能受合金的化學(xué)成分影響，我們提供不同的合金組成 , 以滿足顧客的要求， 我們也可以根據(jù)客戶要求制造特殊規(guī)格的陽極。鋁合金陽極生產(chǎn)執(zhí)行GB4948－2002《鋁－鋅－銦系合金犧牲陽極》。

在用標(biāo)準(zhǔn)的外加電流陰極保護(hù)管線上用電流梯度法進(jìn)行檢測(cè)時(shí)，儀器往往不會(huì)受保護(hù)電流上諧波的影響，所以不將管線上的陰保電流斷開是可以接受的，但當(dāng)施加檢測(cè)信號(hào)點(diǎn)與陰保站極近時(shí)，出于發(fā)射機(jī)的安全考慮，好斷開管線上的陰保電流。在使用PCM的“皮爾遜法”(地面電場法或稱用A型字架測(cè)量法)對(duì)管道的任一部分進(jìn)行檢測(cè)過程中，檢測(cè)信號(hào)可能會(huì)發(fā)生明顯的失真。

The uniform pressure band is generally set up every 300-500 meters on the pipeline. During the inspection process, it is hoped that all the uniform pressure bands will be separated and this will be done as far as possible within an adjacent 3-5 km range. For most of the oil field pipeline is difficult to do. In this way, the welding joint of the uniform pressure band is represented as a Breakpoint of the embalming layer, and some signals on the tested pipe will be transmitted to its adjacent pipeline; It is also possible that the signal is returned from a pipe through the joint. However, in most cases, the signal strength of the target pipeline is the largest. According to the signal strength of the target pipeline, it is still possible to distinguish the target pipeline to complete the corresponding detection.
