This method can eliminate the requirements related to the processing and production of iron bars and molds, and in the long term, by providing adequate cathodic protection for steel envelopes, the collision problem can be eliminated.
Le ndlela ingasusa izidingo ezihlobene nokucutshungulwa nokukhiqizwa kwemigoqo yensimbi nezikhunta, futhi ngokuhamba kwesikhathi, ngokunikeza ukuvikela okwanele kwe-cathodic ezimvilophini zensimbi, izinkinga zokushayisana zingaqedwa.
