Storage tank welding tips are all here
Storage tank welding project is more common, especially large storage tank welding requirements are more stringent, here is a brief introduction to the operation process and welding skills of tank welding project with large vertical storage tank as an example.
Vertical cylindrical storage tank is a vertical tank composed of a circular tank wall with the central axis perpendicular to the ground, a flat disc-shaped tank bottom and different forms of tank roof, a vertical tank, accessories (such as ladders, platforms, etc.) and accessories (such as liquid level measurement, fire fighting facilities, etc.). General nominal volume greater than 100m? storage tanks called large storage tanks, the standard used: GB50128-2005.
Second, the storage tank foundation
Tank foundation is the place where the tank is placed, requiring strong, solid; it not only affects the aesthetics, and will lead to uneven stresses on the tank. Tank foundation is a civil construction category, must be in accordance with the foundation construction drawings and technical standards requirements. Tank installation must be checked before the foundation of the tank, qualified before installation.
Three, prefabricated assembly
For large vertical storage tank manufacturing, general division, segmentation and combination of prefabrication, and then assembly, to improve production efficiency is very helpful, the first should be the construction of storage tanks selected materials and accessories for review, prefabricated assembly includes: bottom plate, wall plate, floating roof and internal floating roof, fixed roof top plate, wind ring, strengthening ring, wrapped edge angle steel and other components, parts.
Fourth, the welding of storage tanks
1, welding process assessment
For the first use of steel, according to the steel number, plate thickness, welding method
