What are the uses of stainless steel filters?

- May 17, 2018-

  The stainless steel filter is mainly used for acid, helium, screening and filtration. As the oil industry as the mud filter, chemical fiber industry as a sieve filter, electroplating industry for pickling filter to use. The stainless steel filter produced by our factory as a construction safety filter is not easy to be cut by hard objects. It can adapt to the bad outdoor tasks and can be used repeatedly. It can be used repeatedly with only a single investment, reducing the cost. When stainless steel strainers are used in engineering water conservancy, they can be usefully prevented from being washed away by the currents to form bank collapses and ensure the safety of the full reservoir watercourse. If it is found that there are pores on the surface of the stainless steel electric arc welding filter, the reason for the occurrence of the appearance of the pores is that the stainless steel containing C, S, and Si has a high amount of pores.

  The processing method is either to change the stainless steel data or use a low-hydrogen residue electrode. Holes are easily formed in the soldering area. Therefore, the welding site is required to remove dirt, rust, and other dirt before welding. The requirements for welding with low hydrogen electrodes are more stringent. Welding current is too large. The red coating of the second half of the electrode becomes red, and pores are also easily generated. Therefore it is required to accept suitable welding standards. The maximum limit of welding current is that the tail of the welding rod is not red. Low-hydrogen electrodes absorb moisture easily, so they must be baked at 350°C for about 1 hour before use. Otherwise it is easy to show pores. Welding wave joint porosity: The use of low hydrogen electrode is often easy to show appearance and internal porosity at the joint of the weld joint. Its treatment method: welding wave joint, should be at the beginning of the weld to deflect from the arc pit 9 ~ 10mm start arc, arc After the combustion, the reverse transport rod is first returned to the crater position, and sufficient melting and further progress, or arcing at the weld can prevent the occurrence of this type of stomata.
