The standard details various jointing methods to ensure leak-tightness and structural integrity, including:
: Push-fit connections that rely on pre-formed push-on rubber gaskets positioned inside the socket profile. These absorb minor longitudinal micro-movements without leaking.
to ensure high-quality surface finish [1].
: 100% visual + 20% radiographic (RT) on girth welds.
The standard outlines several key requirements for steel tubes and pipes, including:
Used for smaller diameter tubes or situations where welding is not permitted.
Preferred for high-pressure applications where a permanent, continuous pipeline is required. Mechanical Couplings:
Utilizing elastomeric seals in accordance with EN 681-1 .
Joints must be designed to withstand internal and external pressures experienced in water distribution networks.
Joints must withstand internal pressure and external loads without leakage or failure.
