To ensure the success of on-line welding procedures, certain issues must be addressed to guarantee public, environmental, and worker safety both during and after welding.

EWI has developed In-Service Welding Guidelines, a collection of procedures which are documented by both Welding Procedure Specifications (WPSs) and Procedure Qualification Records (PQRs). These procedures – qualified to the requirements of API 1104, API 1107, ASME Section IX, BS4515, BS6990, and CSA Z662 – were developed using both laboratory mock-ups and full-scale pipes, and validated by making field welds onto live gas pipelines. They apply to both hot tap branch connections and sleeve repairs (both fillet and groove welds). The use of properly qualified procedures provides a cost-effective solution while minimizing the risk of hydrogen cracking by eliminating the high costs of unnecessarily complex procedures.

Benefits

Guidelines are provided for:

  • Repair Type
  • Method Selection
  • Differing Conditions

Welding directly onto in-service pipelines is beneficial in saving time, labor, and expense:

  • Uninterrupted Flow: Maintaining product flow eliminates the income lost through non-delivery. It also eliminates the expense and potential environmental impact of draining liquid pipeline contents and venting gas to the atmosphere.
  • Best Welding Practice: Employing these procedures can significantly reduce the time required for welding and the potential for failures attributable to poor welding practice.

Pricing And Contact Information

In-Service Welding Guidelines is available to EWI members for $12,500 and to nonmembers for $16,000.
