RESEARCH / DEVELOPMENT / TECHNOLOGY PIPELINE TECHNOLOGY JOURNAL 23 Previous seam weld failures of HFW carbon and LAS line pipes have deterred projects from selecting it in the past with preference towards the SMLS equivalent. However, over the past 20 years several manufactures have demon- strated their capability (track record) to produce high-qual- ity reliable HFW pipe. In recognition of this, HFW carbon and LAS line pipe should only be procured from pipe mills with the necessary technology and proven capability (track record) to meet the specific project requirements. For each project, the purchaser should always audit the mills quality assurance/quality control (QA/QC), steel quality, reliability of process control/monitoring and NDT. It is important to ensure that these requirements are clearly specified and confirmed by sufficient independent inspection of the criti- cal stages to mitigate seam weld failure. It is proposed that HFW CS and LAS pipe can be consid- ered as a viable alternative solution to SMLS equivalent for a range of scopes that fall into its capability range.
