is the European standard that defines the methods and requirements for connecting non-alloy steel tubes and fittings used specifically for conveying water and other aqueous liquids . It provides a standardized framework for the strength, integrity, and testing of these joints to ensure they can withstand long-term operational pressure without leaking or failing . Scope and Purpose
To qualify a jointing procedure, destructive testing must be performed on test pieces. BS EN 10311 references other standards for specific tests:
The standard’s qualitative tables help you justify these decisions to a notified body or client.
BS EN 10311 is a European Standard that specifies the requirements for non-destructive testing of welds in metallic materials. Here's a brief overview:
Always ensure you are using the latest version or any amendments, as indicated on the BSI or relevant standards body website. Conclusion Bs En 10311 Pdf
Ideal for faster installation, often used in underground water pipelines.
Elias highlighted the paragraph in the PDF. The digital yellow ink glowed on the screen. The bridge hadn't sagged because the steel was weak; it had sagged because the connection was "hard" but "brittle." The bolts were taking the load in shear when they should have been in bearing.
: Specifies the necessary tests to ensure the joint can withstand operating pressures without leakage or failure. Relationship with Other Standards : This standard should be used in conjunction with BS EN 10224
The standard applies to pipelines used for the conveyance of fluids (liquids, gases, or slurries) under pressure. It is commonly cited in the water, gas, oil, and chemical processing industries. is the European standard that defines the methods
BS EN 10311:2005 is a British and European standard that defines requirements for joints connecting steel tubes and fittings
The standard applies specifically to steel tubes used for transporting water. It is important to note that while it covers general water transport, it may not apply to high-pressure steam pipes or specialized chemical pipelines. Non-alloy quality steel. Types: Seamless and welded (HFW, SAW, etc.).
Joints that allow for significant angular deflection or center-line offsets are explicitly excluded . Availability of the PDF
: This standard is often used in conjunction with BS EN 10311. Together, they superseded the older BS 534:1990 Potable Water Regulations BS EN 10311 references other standards for specific
Connections between tubes or fittings with ends prepared according to EN 10224.
One of the most common points of confusion is how this standard interacts with others.
Provides European harmonized standards.
