The 22nd Edition (July 2021) provides specific allowable limits for common weld defects: Documented proof that a specific procedure produces sound
API Standard 1104, , is the primary global standard for gas and arc welding in the construction and repair of pipelines. It ensures structural integrity for systems transporting crude oil, petroleum products, fuel gases, and other fluids. 🛠️ Key Components Individual indications are typically limited to 1 in
Generally prohibited, though shallow crater/star cracks under 5/32 in. (4 mm) may be acceptable in some contexts.
Individual indications are typically limited to 1 in. (25 mm) in a continuous 12 in. weld length.
The standard covers the entire lifecycle of a pipeline weld to ensure safety and compliance:
