Stainless steel flanges have become increasingly popular in various industries due to their excellent corrosion resistance, durability, and strength. These flanges are widely used in high-performance applications such as oil and gas, chemical processing, and petrochemical industries.
Stainless steel flanges are designed to connect pipes, valves, pumps, and other equipment to form a piping system. They are available in different sizes, shapes, and types to suit various applications and requirements. Stainless steel flanges are made from high-quality materials such as 304, 316, and 316L stainless steel, which provides superior resistance to corrosion, heat, and pressure.
Large stainless steel flanges will rust in the general environment, mainly on any surface, free iron will rust and cause stainless steel to corrode. Therefore, it must be cleared. The floating powder can generally be removed together with the dust. Some are very sticky and must be treated as embedded iron.
In addition to dust, there are many sources of surface iron, including cleaning with ordinary carbon steel wire brushes and shot blasting with sand, glass beads or other abrasives previously used on ordinary carbon steel, low alloy steel or iron castings, or Grinding the aforementioned non-stainless steel products near the stainless steel flanges and equipment. If no protective measures are taken for the stainless steel flange during blanking or hoisting, the iron on the wire rope, hoisting gear and working table is easy to embed or stain the surface.
Rust removal method for stainless steel flange: immerse the flange in hydrochloric acid, the principle is to reduce the rust to iron, but this method has certain dangers, hydrochloric acid is a corrosive substance, harmful to the human body, be careful not to touch it when operating To the human body, there is still a finished flange and then neutralized with alkali, do not touch your hands directly.
