Alloy Steel P22 Pipes
We are a known manufacturer, exporter and supplier of AS P22 Pipes, which is often used for building nuclear reprocessing plants. Alloy Steel P22 Seamless Pipes is used in wire for severe cold heading such as the manufacture of cross recess screws, as it has excellent corrosion resistance. And reason for this is also that brittle phases deposited in this case of Alloy Steel P22 Welded Pipes and that lead to reduced ductility is less because the process of laser welding accompanied high temperature and cooling rate is too high. Alloy Steel P22 EFW Pipes offers exceptional corrosion resistance, the ease with which it can be steam cleaned and sterilized. And lack of need for surface coatings has also influenced the use of Alloy Steel P22 ERW Pipes in commercial kitchens and food processing plants.
Special instruction for welding of Alloy Steel P22 Round Pipes is to adopt proper sequence, remove the slag with stainless steel wire brush, and redry electrodes at 300 Degree C for 1hour for better results. Alloy Steel P22 Square Pipes are used in corrosion resistant electrical enclosures, auto molding and trim, wheel covers, kitchen equipment, etc. Alloy Steel P22 Rectangular Pipes are also magnetic, a property that can be used to easily differentiate them from common austenitic grades of alloys. Alloy Steel P22 Electropolish Pipes is a utility steel resistant to wet abrasion and mild corrosion, which fine rippled bead and easily detachable slag.
