So what is the cause, what is the reaction condition? Let&#8217;s go find the answer together now.<\/p>\n<p>Our country has a hot and humid tropical monsoon climate, plus a long coastline, so it has created an ideal environment for high-speed metal wear. The following are the necessary \u2013 sufficient conditions to cause the phenomenon:<\/p>\n<ul>\n<li>The main agent is the presence of both water and oxygen elements.<\/li>\n<li>Pipeline equipment made of steel (Fe-C) in contact with water (or steam) and oxygen gas results in the following reaction:<\/li>\n<\/ul>\n<p>3Fe + 4H2O = Fe3O4 + 4H2\u2191<\/p>\n<p>3Fe + 2O2 = Fe3O4<\/p>\n<p>Or cause a redox reaction in the electrolyte environment (low resistance soil, acid, alkali, salt, ..) to produce Fe3O4nH2O (rust). This process will produce a high-speed corrosion current.<\/p>\n<ul>\n<li>In some cases, this phenomenon can occur without the presence of oxygen. Especially the sulphate corrosive form. Elemental sulfur is produced by microorganisms that decompose organic impurities.<\/li>\n<\/ul>\n<div class=\"wp-block-image is-style-default\">\n<figure class=\"aligncenter size-full\"><a href=\"https:\/\/multichem.com.vn\/wp-content\/uploads\/2022\/12\/AhCiNs1BLr.jpg\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" class=\"lazyload wp-image-4592\" src=\"https:\/\/multichem.com.vn\/wp-content\/uploads\/2022\/12\/AhCiNs1BLr.jpg\" data-orig-src=\"https:\/\/multichem.com.vn\/wp-content\/uploads\/2022\/12\/AhCiNs1BLr.jpg\" data-sizes=\"auto\" data-orig-sizes=\"(max-width: 800px) 100vw, 800px\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%27800%27%20height%3D%27531%27%20viewBox%3D%270%200%20800%20531%27%3E%3Crect%20width%3D%27800%27%20height%3D%27531%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" data-srcset=\"https:\/\/multichem.com.vn\/wp-content\/uploads\/2022\/12\/AhCiNs1BLr.jpg 800w, https:\/\/multichem.com.vn\/wp-content\/uploads\/2022\/12\/AhCiNs1BLr-300x199.jpg 300w, https:\/\/multichem.com.vn\/wp-content\/uploads\/2022\/12\/AhCiNs1BLr-768x510.jpg 768w, https:\/\/multichem.com.vn\/wp-content\/uploads\/2022\/12\/AhCiNs1BLr-18x12.jpg 18w, https:\/\/multichem.com.vn\/wp-content\/uploads\/2022\/12\/AhCiNs1BLr-599x398.jpg 599w\" alt=\"Causes of pipeline corrosion\" width=\"800\" height=\"531\" title=\"\"><\/a><\/figure>\n<\/div>\n<h1><span class=\"ez-toc-section\" id=\"Distinguishing_types_of_pipeline_corrosion\"><\/span>Distinguishing types of pipeline corrosion<span class=\"ez-toc-section-end\"><\/span><\/h1>\n<p>Common types of pipeline corrosion today:<\/p>\n<ul>\n<li><strong>Wide area corrosion:<\/strong> uniform corrosion rate on all surfaces, throughout the length of the pipeline.

The transported fluids contain many impurities in contact with the pipe surface for a long time, causing wear.<\/li>\n<li><strong>Corrosion in the form of stress:<\/strong> due to the compression process, ground loads, rocks, sand, etc., deform the pipeline.
