The corrosion resistance of carbon steel stamping elbows depends on the alloying elements contained in the steel.Chromium is the basic element to make carbon steel elbow corrosion resistance, when the amount of chromium in steel reaches about 1.2%, chromium and the oxygen in the erosion medium, forming a very thin oxide film on the steel surface, can prevent further erosion of the steel matrix.
Stainless steel stamping elbows do not produce erosion, pitting, corrosion or wear.Stainless steel is still one of the strongest metals used in construction.Because of its excellent corrosion resistance, stainless steel enables structural components to maintain the integrity of the engineering design permanently.Stainless steel is also one of the strongest metal materials used in construction.Because of its excellent corrosion resistance, stainless steel enables structural components to maintain the integrity of the engineering design permanently.
Chromium-containing stainless steel is also a combination of mechanical strength and high extensibility, easy to manufacture parts, to meet the needs of architects and structural designers.All metals react with oxygen in the atmosphere to form an oxide film on the surface.Use and installation of carbon steel stamping elbow: the elbow is used for connecting the pipe at the bend, connecting two pipes with the same nominal diameter to make the pipe turn at an Angle, dividing carbon steel elbow, cast steel elbow, alloy steel elbow, stainless steel elbow, copper elbow, aluminum alloy elbow and so on.
Use analysis of stamping elbow:
1. Stamping elbow is suitable for pipeline system in petroleum, natural gas, chemical industry, hydropower, construction and boiler industries.
2. Without tube blank as raw material, the cost of tube making equipment and mould can be saved, and the carbon steel elbow with arbitrary large diameter and relatively thin wall thickness can be obtained.
3. Due to the above two reasons, stamping elbow can shorten the manufacturing cycle and greatly reduce the production cost.Since no special equipment is required, it is especially suitable for large carbon steel elbow machining on site.
4. The blank is flat or developable surface, so the blanking is simple, the precision is easy to ensure, and the assembly and welding are convenient.
Because stamping elbow has good comprehensive performance, it is widely used in chemical engineering, construction, water supply, drainage, petroleum, heavy and light industry, refrigeration, sanitation, water heating, fire protection, electric power, aerospace, shipbuilding and other basic engineering.
