The inspection required sand picking of the entire cold box, so the installation of the instrument piping should not be taken lightly. Attention is pa
The clumping or crumbling of pearl sand from a height will cause serious injury and damage to pipes and equipment in the cold box, and may even cause
The silica gel of the air separation cold box system seal fails, the lack of seal is the top space is in a negative pressure state, the cold box top p
The scope of work is to check for problems and safety hazards, to carefully analyse the causes of deformation or damage and to propose feasible soluti
The first and foremost task of cold box maintenance is to drain the pearlescent sand from the cold box, and with the increasing size of air separation
After the air separation equipment is put into operation, in long-term operation due to temperature stress and material fatigue will cause a number of
Steel structure cold box design mainly uses square cold box, using ring ladder or fold back ladder, main cold box and heat exchanger cold box separate
In pipelines, secondary stresses are generally caused by the action of thermal expansion and contraction and by end point displacement.
Secondary stresses are stresses that arise due to the constraint received by the deformation of the pipe and are not directly balanced with external f
Primary stresses are those resulting from the action of an applied load, such as pressure or gravity. The arrangement of pipes and the setting of supp
Air separation equipment temperature below -20 degrees, resulting in poor operating conditions, steel in low temperature conditions, will gradually ch
