Type of Stub End / Lap Joint
Type A Stub End / Lap Joint, Decreased pressure factor
Same wall thickness on the weld ends and on the fi tting body as for a pipe with the same specifi ed wall thickness. Their resistance to internal pressure is less than that of a pipe with the same diameter, same wall thickness and made of the same grade of steel.
The required calculation methods are based on the calculation standards defined in EN 13480-3
Type B Stub End / Lap Joint, Full pressure factor
Increased wall thicknesses on the fi tting body, same resistance to internal pressure as for a pipe with the same diameter, same wall thickness and made of the same grade of steel.
The required calculation methods are based on the calculation standards defined in EN 13480-3
