There is a good variety of cleaning spiral style, you can use a wire brush, which is rough sandpaper these tools to conduct an overview of the disposal of the steel, so that it can spiral before doing heavy cleaning cleaning if you can remove loose and flips oxide, rust and welding slag and other dirty tools. If you think this style fighting strength of trouble, you can choose to use two kinds of chemical and electrolytic pickling another way to deal with these two conventions are often used in the mouth, and also rough. Spiral pipeline corrosion chemical pickling is not only accepted the style of electricity connected. Chemical cleaning effect is very fast, organized well in advance as long as it will not cause any pollution. Cleaning spiral very serious altercation pace, must be detailed.
Spiral mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, is the development of the 20 key products. For the transport of liquids: water supply, drainage, sewage treatment works, lose mud, sea water. For gas transportation: gas, steam, liquefied petroleum gas. For structural purposes: as piling pipe for bridges; docks, roads, building structure pipe, marine piling pipe.
Also known as spiral or helical spiral piling pipe, is a low-carbon steel or low alloy steel strip at a certain angle of the helix (called molding angle) rolled into a tube, then welded together to form the tube, it can be produced with a narrow strip of large diameter steel pipe. Spiral is mainly used for oil and gas pipelines, its diameter * thickness expressed. Spiral single-sided and double-sided welding welding, pipe should ensure that hydrostatic test, weld tensile strength and cold performance to meet the requirements.
