3pe anticorrosive steel pipe from the process can be divided into manual anticorrosion and equipment anticorrosion, the two kinds of anticorrosion difference mainly lies in the following points:
1: Manual anticorrosion cost is relatively low, the main tools are rolls, spray guns, simple production process, equipment anticorrosion processing cost is relatively high, mainly rust removal equipment, spraying, cooling and other equipment.
2: Manual anticorrosion is more flexible, the number of small can also be processed, and the need for equipment processing anticorrosion is large.
3: The service life of steel pipe after manual anti-corrosion processing is shorter than that of equipment anti-corrosion processing, and the quality is relatively poor.
4: The steel pipe anticorrosive thickness of manual anticorrosive processing is not uniform, the thickness difference is large, the steel pipe of equipment anticorrosive processing is uniform, and the adhesion is strong.
5: Manual anti-corrosion processing pollution is serious, equipment anti-corrosion processing through the tail gas treatment system pollution is small.
With the increase of national environmental protection, the manual anticorrosive processing steel pipe has been strictly managed, the basic requirements of the manual anticorrosive steel pipe, coupled with the improvement of the national quality requirements for anticorrosive steel pipe, from the source of the design directly requires the use of equipment processing, so that the quality is guaranteed, the environment has been protected, but the cost has increased.
