Washing of cs seamless pipe

CS seamless pipe refers to a seamless pipe that is perforated from a whole round steel and has no welds on the surface. Mainly used as petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high-precision structural steel pipe for automobile, tractor and aviation. The cs seamless pipe will use the pickling step during processing, and it usually needs to be washed with water after the pickling.

What should be paid attention to in cs seamless washing?

1) When the cs seamless steel pipe is washed with water, it needs to be carried out in a flowing clean water tank.In this way, secondary pollution can be avoided. When washing, the cs seamless steel pipe needs to be completely immersed in water. At this time, the sling should be loosened, and it can be lifted up and down three to four times;

2) When the cs seamless steel pipe is washed with water, it is necessary to clean the water in the steel pipe to avoid water corrosion and oxidation of the steel pipe, so it is very necessary to treat the solvent as soon as possible;

3) When the cs seamless steel pipe is washed with water, it should be noted that it cannot cross the pickling tank, so as to avoid accidents, slipping or falling into the acid tank and being corroded by residual hydrochloric acid;

4) When the cs seamless steel pipe is washed with water, the iron salt content standard must be controlled within a certain range, and it cannot exceed the standard, otherwise the cs seamless steel pipe may be damaged.

The pickling of the cs seamless pipe is to remove the surface oxide scaleAfter lubricating treatment (carbon steel-phosphorus saponification, stainless steel-tallow lime, copper-aluminum tube-oiling, using the old process-copper plating), and then deep-drawing processing. If the cs seamless pipe is not pickled, there may be oxides and oil stains on the surface, and the phosphating solution may not be able to remove them, and the phosphating quality will be reduced. Moreover, in the manufacturing process of the cs seamless pipe, after multiple processes, if a little care is not taken, it will leave scars on the surface of the seamless pipe, which will reduce the corrosion resistance of the parts and directly affect the service life;After pickling, a protective film will be formed on the surface of the cs seamless pipe, which improves the corrosion resistance of the cs seamless pipe.
