Power Plant Special Pipe Reducer 10CrMoAl Seawater Corrosion Resistant Pipe Reducer Alloy Pipe Reducer
Features and applications:
It is a special steel that is resistant to seawater corrosion. 10CrMoAl material is the most ideal material for pipelines and processed parts for coastal power plants, coastal oil fields, coastal natural gas and petrochemical plants to transport water, oil and gas and seawater-containing media. It can also be used to make valve flanges.

use:
Material, mainly used to make pipes and equipment. It has the advantages of strong corrosion resistance and convenient installation.
Reasons for corrosion resistance:
1. The Al (aluminum) in the 10CrMoAl material can chemically react with the O (oxygen) in the air to form Al2O3 (aluminum trioxide). This forms a protective film, which is both corrosion-resistant and corrosion-resistant.
2. The Cr (chromium) and Mo (molybdenum) ions in 10CrMoAl can automatically supplement the gaps formed by the pitting corrosion of Cl (chlorine) ions on the steel in the seawater, forming a dense protective layer to prevent the pitting corrosion from developing in depth. In turn, it is resistant to corrosion and prolongs the service life.
welding:
The 10CrMoAl material has better welding performance and is equipped with a special corrosion-resistant electrode "sea O3", without special welding requirements.
