What are the polishing processes that affect stainless steel elbows

The elbow of the stainless steel elbow is welded to the steel pipe, requiring a heating process to be welded together along the entire cross section. Under normal circumstances, there are two kinds of heating welding and flash butt welding, high production efficiency, easy to complete the automation technology, so it has been widely used

The one we are talking about below is mainly for a finishing process, which is an option for pipe fittings with less smooth surfaces

So the impact of stainless steel elbow polishing process is what

The grinding and polishing process of stainless steel elbow, the key advantage of chemical polishing is that the microscopic convex part of the material surface is dissolved in the chemical substance rather than the concave part, so as to obtain a smooth surface

There is no need for complex facilities to polish and polish complex style products together, can effectively polish and polish large quantities of products together

In the rough polishing link, hold the product sample tightly, repeat along the radius of the disc, adjust the resistance evenly, to prevent the resistance is too large when polishing and polishing, sometimes sprinkle the polish, after the polish resistance will gradually decrease, the polish concentration will reduce until the fine friction traces disappear, rough polishing and polishing sample first clean with water

The polishing marks left by rough polishing are removed by small polishing. The polishing surface is glossy and smooth. The polishing machine used by fine polishing is basically the same as that of rough polishing machinery

ffecting the characteristics of stainless steel elbow grinding and polishing conditions, surface there are some scratches, there are some stray points, and a part of acid treatment flaws, deep drawing, large deformation area surface will produce black spots, affecting the BQ characteristics, the materIf the hardness standard is too low, it is not easy to polish and polish. If the hardness standard is too low, the surface is easy to produce orange peel lines when drawing, which affects the BQ characteristics. BQ with high hardness standard is relatively good.

What should we do to improve butt welding techniques

Most stainless steel elbow pipe fittings are butt welded. In order to improve the quality of butt welding, a groove with corresponding direction and corresponding edge is opened on both sides. This standard is also very strict

The thickness, direction and deviation area of pipe fittings will be required. The geometric size is many more than that of pipe fittings, so this technology is still at the level of postgraduate technician

Is 316 stainless steel the same as surgical steel?

It is the addition of chromium that gives the steel its unique stainless, corrosion-resisting properties. Austenitic 304 and 316 stainless steels are considered surgical or medical-grade stainless steels, they are the most commons stainless steels.
