Short answer. Pipe ends are an engineering decision, not a packing detail. The end configuration controls field fit-up, how the internal lining is closed out, and how the girth weld is coated.
- State butt-weld ends, flanges or other connections on the RFQ, together with the welding procedure.
- Bevel geometry follows the approved WPS/PQR; do not leave it to the fabricator’s discretion.
- Lining termination and pipe-end cutback length must match the chosen field joint system.
- Pipe-end protectors for shipping are specified separately from the permanent end preparation.
AWWA C200 covers the pipe and C206 field welding; the approved WPS/PQR governs bevel preparation.
Because many Southeast Asian projects involve barge legs and a second lift, the permanent bevel also needs a shipping protector that can be removed without damaging the lining termination.
