Stainless steel wire mesh we are professional
Our main stainless steel wire mesh, next I will introduce to you stainless steel wire mesh.I hope this article can help you.
Stainless steel wire mesh is mainly used for screening and filtration in acid and alkali environment.It is mainly used in oil industry as mud net, chemical and chemical fiber industry as screen filter and electroplating industry as pickling net.The stainless steel wire mesh produced by our factory is not easy to be cut by hard objects as a safety net for building, can adapt to the harsh working environment outdoors, can be reused, can be used for many times with only one input, reducing the cost.When the stainless steel wire mesh work is used in the project water conservancy, it can effectively prevent the bank from being washed away by the current, thus ensuring the safety of the full reservoir river.If it is found that there are pores on the surface of stainless steel welding line, the reason for producing surface pores is that the pores are easy to appear due to the high content of C, S and Si in stainless steel.The solution is to either replace the stainless steel material or use low hydrogen slag welding rod.The welding position is not clean also easy to produce air holes.Therefore, it is required to remove dirt such as oil and rust before welding.Welding with low hydrogen electrode is more stringent.Excessive welding current.To make the back part of the electrode skin red, also easy to produce pores.Therefore, suitable welding specification is required.The welding current should be not red at the end of the electrode.Low hydrogen electrode easy absorption of moisture, so before use must be under 350 ℃ temperature bake for 1 hour or so.Otherwise, the stoma is easy to appear.Wave welding joint porosity: using low hydrogen electrode easily appears in the weld joint surface and internal porosity, its solution: wave welding joint, should be the direction of the weld from 9 ~ 10 mm of arc crater starting arc, arc burning, first as a reverse bar to return to the arc pit position, be fully melted forward again, or at the weld arc can avoid this type of porosity.
Stainless steel wire mesh surface cleaning, pickling and passivation, in addition to the maximum enhancement of corrosion resistance, but also to prevent product contamination and aesthetic effect.The requirement that containers made of stainless steel wire mesh and composite steel plate should be subjected to acid cleaning passivation is for the purpose of filtration used in petrochemical industry, because these devices are used for direct contact with corrosive medium.For other industries, if not for the purpose of antisepsis, only based on the cleaning and aesthetic requirements, while the use of stainless steel materials do not require pickling passivation.However, the welding line of stainless steel equipment still needs to be processed by pickling and passivation.
