Storage tank sacrifice anode protection lowest price

為套管內(nèi)的管道單獨施加陰極保護可以減小由于套管短路而對整條管道陰極保護的影響，但是無助于套管內(nèi)部主管道陰極保護的改善。 如果套管與主管發(fā)生短路需要確定短路點并進行修復(fù)�？梢允褂眯铍姵匾约皟蓧K萬用表來確定短路點。首先給套管通電I，測量出該電流下套管上的電壓降V1。然后給套管以及主管通同樣大小的電流I，再次測量套管上的電壓降V2。兩次測量的電壓降的比V1/V2等于套管長度S1與短路點距離S2之比。

主要性能：

電化學(xué)性能、單位重量的陽極材料發(fā)電量大，約為鋅陽極的3倍，鎂陽極的2倍。在海水及含氯離子的其它介質(zhì)中，性能良好，發(fā)出電流的自調(diào)節(jié)能力強。

使用范圍：

鋁合金犧牲陽極適用于海水介質(zhì)中的船舶、機械設(shè)備、海洋工程和海港設(shè)施以及海泥中管道、電纜等設(shè)施金屬防腐蝕的陰極保護。

鋁犧牲陽極的使用環(huán)境

處在海水環(huán)境中的大部分金屬設(shè)備或者貨品儲罐內(nèi)部底板的陰極保護是不能用在氯離子含量低的土壤環(huán)境中。鋁犧牲陽極的電極電位為-1.05伏特 ，當周圍溫度高于49攝氏度時鋁犧牲陽極的電容量隨著溫度的增長而遞減，可以參考公式：Z=2500-27（T-20），T陽極工作溫度，單位℃。在咸水環(huán)境中，鋁犧牲陽極的電流容量可能會降低一半。鋁犧牲陽極可以直接與需要保護的設(shè)備結(jié)構(gòu)固定在一起而不需要其他物質(zhì)作為填料。海底管道保護用立博防腐Libo corrosion protection for submarine pipeline protection

The protection in the tank has been used for many years. The original use of sacrificial anodes, and some systems are still using sacrificial anodes, such as the protection of seawater ballast tankers. The bottom of the tank is generally plate and rod. The plate anode is easier to weld in the inner frame of the bottom flame, and the rod anode is suitable for installation on the curved side. The anode should be grouped or arranged separately to ensure that the current distribution on the entire protective surface is as uniform as possible. Cathodic protection is an effective corrosion cool measure, but for people who are not completely familiar with it, it is a bit mysterious. Obviously, many people feel that cathodic protection is a complex.Libo corrosion protection for submarine pipeline protection
