If the inner diameter of the jacketed tube is ≤40 mm, which connection method is more appropriate for the inner tube: socket welding or butt welding?
For ordinary pipes, the choice depends on the type of pressure applied to the medium; weld connections offer higher strength, reaching 80%-100% of the strength of the base material； The strength of socket welding is relatively low. Socket welding is commonly used for low-pressure, small-diameter connections ； Butt welding is suitable for applications involving high pressure, high temperature, or highly corrosive media. However, butt welding should be used for jacketed pipes, with socket welding being rarely employed; first, check the relevant specification documents to see if there are any requirements
