Thick-walled seamless steel pipe damp treatment and cleaning

The thick-walled seamless steel pipe is an element with a small amount of alloys. The alloy is made of a variety of metals. With the continuous use of the thick-walled seamless steel pipe, the various properties of the thick-walled seamless steel pipe And common basic advantages have also received widespread attention. In fact, thick-walled seamless steel pipes are harder than ordinary steel plates, and are more resistant to high temperature and high pressure. The usefulness in the production and design of the species is relatively huge.

Shake gently, the sound is hard and brittle, if the wear-resistant welding wire is damp, the sound will be dull. The moisture content of the wear-resistant composite steel plate is very high when the wet thick-walled seamless steel pipe is welded by electric welding, and even water vapor can be seen from the surface of the wear-resistant composite steel plate, or when more than half of the wear-resistant composite steel plate is welded, it is found that There are cracks at the end of the wear-resistant composite steel plate.

So, how to deal with the thick-walled seamless steel pipe after being damp?

1) Because the wet core has mild rust, most of them are not easy to damage the characteristics.

2) The damp rust is more serious, and it can be considered for degrading application or electric welding of general prefabricated components as appropriate.

3) Moisture is more serious, and even architectural coatings have rust. Although such thick-walled seamless steel pipes have been air-dried, they still cause high stomata or external diffusible hydrogen content during electric welding, so they can be used.

How to clean thick-walled seamless steel pipes properly?

1) It is possible to solve the surface layer of dirty thick-walled seamless steel pipes by means of precipitation washing, manual washing and cleaning.

2) The effect of precipitation flushing was confirmed by placing the same Lu board in the air immediately and placing it in a sheltered place. The efficacy of manual rinsing was determined by manually cleaning the right side of each Lu board every six months with a sponge soaked in soap solution. It was found that the removal of dust and deposits on the surface by precipitation washing and manual cleaning has a good effect on the surface condition compared with the LV boards placed in the shed and not washed. Moreover, it was also found that the production and processing conditions of the surface also have an impact, and the smooth surface of the LV board is better than that of the non-smooth surface.

3) The time interval of brushing is affected by a variety of factors, the key influencing factor is the specified aesthetic standards. Although many thick-walled seamless steel pipe building curtain walls are only washed when the windows are cleaned, generally speaking, the thick-walled seamless steel pipe used for the outside world is brushed twice a year.
