IPELINE NDT AND REPAIR WELDINGPipel

IPELINE NDT AND REPAIR WELDING
Pipeline NDT for weld acceptance will be primarily by Phased Array Ultrasonic Testing (PAUT). The
PAUT will mainly be stationed in Station 5. In most cases, the weld repair will be performed in Station 5
following the sentence of defect. If the repair cannot be completed in time before the next pull, then it
will be moved to station 6.
Detail procedure can be found in PHEWMO-PHE12-PHE24-CPP2-I-PRC-0050 006 NDT Procedure for
Pipeline Installation.
6.6 FIELD JOINT COATING PROCEDURE
After the welding and NDT is completed, the field joint coating operations will commence. The pipeline
field joints consist of Heat Shrink Sleeve application on the bare metal area of the weld joint with 75mm
min. overlap with the pipeline corrosion coating area and a High Density Polyurethane Foam (HDPUF)
infill. Corrosion coating of field joint will typically be performed in Station 8, while the foam infill will
typically be done in Station 9.

Pipabidang sendi terdiri dari panas menyusut lengan aplikasi pada daerah logam telanjang Las bersama dengan 75mmmin. tumpang tindih dengan daerah lapisan korosi pipa dan tinggi kepadatan Polyurethane Foam (HDPUF)pengisi. Lapisan korosi bidang bersama akan biasanya dilakukan di Stasiun 8, sementara pengisi busa akanbiasanya dilakukan di Stasiun 9.
