America *** Chemical Technology Co., Ltd. is a chemical listed companies. Now it has more than 300 tons production scale of urea, compound fertilizer, melamine, nitric acid, ammonium nitrate, woven products, heavy film packaging, diesel exhaust treatment liquid, liquid carbon dioxide and LNG and other chemical products.
Accordingly, during 2012, devoted to the relocation of ammonia urea plant for environmental safety, since dilute nitric acid environments, general stainless steel unable to meet the site requirements, such as long-term use, easy to be corroded.
For this particular use of the environment, on the basis of cost, by many years of level gauge production experience, we recommended that all dilute nitric acid environments use SS304L in the project, this material has low carbon content, for welding or eliminate stress, and SS304L has the good function of resistance to intergranular corrosion, very appropriate for this environment.
Since installation of the liquid level gauge, customer make the good feedback of the use of the level gauge, no corrosion, and no quality problem, and field level display accurate, remote signal is stable and reliable.
