Low Temperature Load Effect Of Steel Structure - Knowledge
Steel will automatically become hard and brittle over time,which is the phenomenon of "aging".The impact toughness of steel under low temperature load should be tested.Equipment steel structure usually puts forward special requirements or higher requirements in the following aspects:

Steel structure:material,surface roughness,tolerance,surface treatment,straightness (or radian) Connection:hole position deviation,bolt grade;welding method,welding standard,welding material;air tightness,non-destructive testing,liquid penetration testing,etc.are required Overall structure of steel structure:verticality.horizontality,etc

Packaging:packaging materials,packaging methods

Storage:ambient temperature,ambient humidity

Transportation:loading and unloading,placing in vehicles,placing in containers,etc.
