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
Stub End / Lap Joint Marking
Each fitting must be permanently marked.
Marking through hard stamping.
- Manufacturer‘s mark or logo
- Country of manufacture (ISO-Code)
- “EN2” as reference to this standard
- “B” for fittings of type B
- Steel name or steel number
- “W” (for welded fittings or fittings that are manufactured from welded pipes)
- Cast number or code number
- Mark of the inspection representative
- Outside diameter D*
- Wall thickness T*
