A Comprehensive Update in the Evaluation of Pipeline Weld

Girth weld defect acceptance criteria are set and enforced in all pipeline constructions in the U.S. per federal regulations (CFR 49 Parts 192 and 195). With the increased use of mechanized welding and AUT (Automated Ultrasonic Testing) in new pipeline constructions, alternative defect acceptance criteria based on ECA (Engineering Critical Assessment) principles are frequently used API 5L Pipe Specification (Updated on 2020) - Octal SteelAPI 5L pipe used for oil and gas transmissions, it includes carbon steel pipe in seamless and welded (ERW, SAW). Covers API 5L Grade B, X42, X46, X52, X56, X60, X65, X70, X80 PSL1, PSL2 and onshore/offshore services.

Challenges for Design, Manufacture and Installation of HP

Abstract With the increasing development of high temperature/high pressure wells, particularly in deep water, riser designs using conventional strength material are utilising increasingly heavier wall thickness pipe, up to 50mm wall thickness in 8" and 10" OD X65 linepipe. Such riser designs are challenging existing seamless linepipe manufacturing and girth welding capabilities.

HEAVY WALL LINE PIPE FOR SEVERE APPLICATIONSHeavy wall seamless pipes are required for deep and ultra-deep water fields [1] as well as for ultra-high pressure applications. LPs currently considered for such applications are seamless pipes with wall thicknesses up to 40-50mm, diameter in the range 8÷16 and YS up to about 490 MPa. The envisaged

The heavy wall pipe was an X65, 10 ¾ OD × 46 mm WT. The welding procedure was a narrow-groove bevel, STT® process for the root pass and the GMAW process for hot, fill, and cap passes. Four full scale fatigue tests were conducted for this investigation, two girth welds per fatigue specimen. Investigation on the strain capacity of girth welds of X80 Jul 01, 2017 · All girth welds were produced by pulsed gas metal arc welding (PGMAW), the major parameters of which are summarised in Table 1 along with a macroscopic photograph of a typical joint cross-section. The pipes were expected to have wall thickness variation in
