The standard focuses on non-alloy and low-alloy steel tubular products used to transport all types of aqueous liquids, including (after proper internal coating). It is widely used by pipeline designers, civil engineers, and quality control personnel. Key Exclusions:
Every fitting or representative sample batch must undergo internal pressure testing. The component must sustain the test pressure without leaking, weeping, or showing signs of permanent plastic deformation. Non-Destructive Testing (NDT)
Be aware that BS EN 10311 is suitable for the following scenarios: Bs En 10311 Pdf
Destructive physical pull tests verify that the joint matches or exceeds baseline pipe strength. Evaluates performance under structural shifts.
Partially. Repair joints (e.g., split sleeves, clock springs) are not explicitly covered, but the qualitative method can be extended. The standard focuses on non-alloy and low-alloy steel
In 2005, after years of collaboration across Europe, the standard was published. The UK adopted it as BS EN 10311 , making it the official benchmark for joints used in steel tubes carrying water or other aqueous liquids (not gas or oil).
Pipelines fail most frequently at joints. According to industry failure databases, approximately 40-50% of all leakage incidents occur at welded seams or mechanical connections. A missing or inadequate standard results in: The component must sustain the test pressure without
Note: Non-destructive testing (NDT) such as radiography or ultrasonic testing is also required for certain applications, but procedure qualification always requires destructive validation.
