What is BS EN 14141 - Valves for natural gas transportation in pipelines about?
BS EN 14141 applies to all valves (plug, ball, gate, and check valves) used in onshore transmission pipelines for transport of natural gas in accordance with EN 1594, but with a differing temperature range according to the following three classes in accordance with EN 682:
- - 10 °C to 60 °C
- - 20 °C to 60 °C
- The range stated by the purchaser for special design.
BS EN 14141 comprises all valves which are components of the pipeline.
BS EN 14141 specifies valves for pipelines with a maximum operating pressure (MOP) over 16 bar.
BS EN 14141 specifies requirements and appropriate verification tests carried out during production and for certification, purposes to verify that the valves conform to the requirements. A summary of the product and type tests is given in Annex G.
BS EN 14141 makes reference to EN 13942. All the requirements of EN 13942 should be met unless otherwise stated. Paragraphs marked with a dot [•] indicate requirements that are identical to EN 13942.
Note 1: Control valves and safety valves are excluded from the scope of BS EN 14141.
Note 2: Additional national requirements and tests in accordance with individual national legal regulations not yet harmonized may be necessary and are to be advised in the purchase order.
Who is BS EN 14141 - Valves for natural gas transportation in pipelines for?
BS EN 14141 on valves for natural gas transportation in pipelines is useful for:
- Manufacturers and suppliers of valves
- Purchaser of valves
- Design and construction and operation teams
- Testing laboratories
- Natural gas industry
- Onshore natural gas systems
Why should you use BS EN 14141 - Valves for natural gas transportation in pipelines?
The significant properties of valves designed for a special application are defined by performance
requirements accompanied by the description of tests to be carried out as specified in BS EN 14141:
- By the manufacturer on the product during the manufacture and
- By an independent accepted body on test samples for certification purposes to give proof that the valve meets the performance requirements of BS EN 14141.
A type test is included in BS EN 14141 to satisfy the requirements of EN 1594.
BS EN 14141 provides guidance on the design and dimensions of the valves to ensure that the valves withstand safely all stresses occurring under operating conditions.
Compliance to guidelines specified in BS EN 14141 allows welding without damage of the internal parts of the valve.
Functional test on clean gas specified in BS EN 14141, helps determine the ability to function under the influence of clean gas and appropriate operation. This means that the valve withstands several operation cycles under full differential pressure without damage.
Overall, quality assurance can be achieved by users of BS EN 14141, while manufacturing valves - plug, ball, gate, and check valves used in onshore transmission pipelines for transport of natural gas.
BS EN 14141 helps ensure efficient transport of natural gas using valves in transmission pipelines to control, regulate and open/close the flow and pressure of natural gas.
