Several ways to remove rust from seamless steel pipe

普通碳钢无缝钢管n基本不耐腐蚀，如果没有好的存放场地而是放置在室外或者潮湿的环境下，碳钢都会生锈。这就需要对他进行除锈处理。

Ordinary carbon steel seamless steel pipe n is basically not corrosion-resistant, if there is no good storage site but placed outdoors or in a humid environment, carbon steel will rust. This requires rust treatment for him.

第一种方式：酸洗

The first way: pickling.

一般用化学和电解两种方法做酸洗处理，管道防腐只采用化学酸洗，可以去除氧化皮、铁锈、旧涂层，有时可用其作为喷砂除锈后的再处理。化学清洗虽然能使表面达到一定的清洁度和粗糙度，但其锚纹浅，而且易对环境造成污染。

Generally, chemical and electrolytic methods are used for pickling treatment. Chemical pickling is only used for pipeline anticorrosion. Oxide scale, rust and old coatings can be removed. Sometimes it can be used as a re-treatment after sand blasting and rust removal. Although chemical cleaning can make the surface reach a certain degree of cleanliness and roughness, but its anchor lines shallow, and easy to cause environmental pollution.

    二：清洗

Two: cleaning

利用溶剂、乳剂清洗钢材表面，以达到去除油、油脂、灰尘、润滑剂和类似的有机物，但它不能去除钢材表面的锈、氧化皮、焊药等，因此在防腐生产中只作为辅助手段。

The surface of steel can be cleaned by solvent and emulsion to remove oil, grease, dust, lubricant and similar organic matter. But it can not remove rust, oxide scale and flux on the surface of steel, so it is only used as auxiliary means in anticorrosion production.

三：工具除锈

Three: tool rust removal

主要使用钢丝刷等工具对钢材表面进行打磨，可以去除松动或翘起的氧化皮、铁锈、焊渣等。冷拔无缝钢管手动工具除锈能达到Sa2级，动力工具除锈可达到Sa3级，若钢材表面附着牢固的氧化铁皮，工具除锈效果不理想，达不到防腐施工要求的锚纹深度

The main use of wire brushes and other tools on the steel surface grinding, can remove loose or raised oxide scale, rust,posuiji.89ix.com xiangbao.37ix.com.cn kongtiao.71ix.comqingwuji.89ix.com paimen.89ix.com kongtiao.37ix.com.cn welding slag and so on. Cold-drawn seamless steel pipe manual tool rust removal can reach Sa2, power tool rust removal can reach Sa3, if the steel surface adhered to a solid oxide scale, tool rust removal effect is not ideal, can not meet the requirements of anti-corrosion construction anchor line depth

四：喷(抛)射除锈

Four: spraying (polishing) to remove rust.

喷(抛)射除锈是通过大功率电机带动喷(抛)射叶片高速旋转，使钢砂、钢丸、铁丝段、矿物质等磨料在离心力作用下对钢管表面进行喷(抛)射处理，不仅可以彻底清除铁锈、氧化物和污物，而且钢管在磨料猛烈冲击和磨擦力的作用下，还能达到所需要的均匀粗糙度。

Spraying (throwing) rust removal is a high-speed rotating spraying (throwing) blade driven by a high-power motor, so that steel sand, steel shot, wire section, minerals and other abrasives under the action of centrifugal force on the surface of steel pipe spraying (throwing) treatment, not only can thoroughly remove rust, oxide and dirt, but also the steel pipe in the abrasive impact and friction of the work It can also achieve the uniform roughness required.

喷(抛)射除锈后，不仅可以扩大管子表面的物理吸附作用，而且可以增强防腐层与管子表面的机械黏附作用。因此，喷(抛)射除锈是管道防腐的必做项目。

After spraying (throwing) rust removal, not only the physical adsorption on the surface of the pipe can be expanded, but also the mechanical adhesion between the coating and the pipe surface can be enhanced. Therefore, spraying (throwing) rust removal is a must for pipeline anticorrosion.
