How to reduce the corrosion of Q345D seamless steel pipe 


Remove the corrosion of Q345D seamless steel pipe. Solvents and emulsions are used to clean the surface of Q345D seamless steel pipe and remove oil, grease, dust, lubricants and similar organics. This method can not remove the corrosion, scale and flux of the surface of the Q345D seamless steel pipe, so it is only an auxiliary means in the anti-corrosion production. 

Tool rust removal. Q345D seamless steel pipe surface is polished with steel brushes and other tools to remove loose or sloping scale, rust and slag. The manual tool can remove rust up to Sa2 level, and the power tool can remove rust up to Sa3 level. If the surface of the Q345D seamless steel pipe is attached to the solid scale, the rust removal effect of the tool is not ideal, and the anti-corrosion construction requirement of the anchor depth cannot be achieved.


Sandblasting and rust removal Q345D seamless steel pipe. Sand blasting not only completely removes the surface rust, oxides and dirt of Q345D seamless steel pipe, but also achieves uniform roughness under abrasive impact and frictio.

Pickling removes corrosion of Q345D seamless steel pipe. Typically, two chemical and electrolytic methods are used for pickling. Only chemical pickling is used in Q345D seamless steel pipe anti-corrosion to remove scale, rust and old coatings. Sometimes it can be used for reprocessing after sand blasting. Although the chemical cleaning can make the surface of Q345D seamless steel pipe reach a certain degree of cleanliness and roughness, its anchor pattern is shallow and it is easy to pollute the environment.

The Straightening of Corten B channel steel To straighten out the bend and shape of Corten B channel steel in rolling, cold, transport, etc., to make the shape correct and straight by straightening so that meet the Corten B channel steel  quality requirements. There are some reasons to impact the straighten of Corten B channel steel. Effect of straightening equipment on quality of  Corten B channel steel . Corten B channel steel straightening generally use 7-roll to 11-roll roller straightening machine. Small Corten B channel steel  using more rolls straightening machine; The roller straightening quality is good, and the roller straightening for large Corten B channel steel is complicated, so it is often used in seven-roll straightener. Effect of straightening technology on quality of Corten B channel steel . Because the Corten B channel steel is an asymmetrical rolled piece, the temperature is low in the thinner part of the...

Elemental Ni has the significant role in JIS G4304 SUS 420J1 steel plate JIS G4304 SUS 420J1 steel plate has certain wear resistance and corrosion resistance, high hardness. JIS G4304 SUS 420J1 steel plate price is the lower class of stainless steel ball. Instruments, transportation tools, household appliances, etc. JIS G4304 SUS 420J1 steel plate is used in the manufacture of parts resistant to atmospheric, steam, water and oxidizing acid corrosion. The addition of element Ni and the increase of Ni content lead to the increase of thermodynamic stability of SUS420J1 alloy, so SUS420J1 alloy has better properties of rust and oxidation resistant medium. With the increase of Ni content, the performance of the reductive medium of SUS420J1 alloy is further improved. It is worth pointing out that nickel is the only important element to improve the stress corrosion of many medium of SUS420J1 alloy.  Nickel also improves the...
