Inspection, Traceability, and the EN 10204 The level of inspection and traceability needs to be determined and agreed upon for each product. If the design in consideration is for a garden hose or a standard American Society of Mechanical Engineers (ASME) pressure vessel, the general consensus is to not pay for the same level of assurance, although, both products are bound to hold pressure.
It is crucial to ensure that the chemical composition and mechanical properties stated on paper are identical to their physical counterparts, which adds further costs to the project. Ideally, the manufacturer would simply need to reach out to a supplier and ask for the required standard and grade of material. The purchasing team is to acquire the materials, with the correct properties, that match those used by the designer in their calculations. Once the numbers have been deemed satisfactory, the manufacturing process may begin as soon as the necessary materials are procured.

Imagine a designer is doing the final verification for a new product. This article will focus on the EN 10204 standard and explore its importance for steel coupling products.īy Davi Correia, Senior Mechanical Engineer
The EN 10204 is the European standard for the inspection documents of steel products, including steel couplings, line pipes, fittings, and sucker rods. One standard often referenced as guidance for such requirements is the EN 10204. As the steel is processed into a finished product (vessels, pipe, fittings, couplings, etc.), there may be need to track it to the original MTC, in order to fulfill traceability requirements. The MTC will include all specifications of the steel product, including dimensions, sizes, weight, chemical composition, mechanical strength, heat treatment status, test results, traceability, and so on. A Mill Test Certificate (MTC) or a Mill Test Report (MTR) is an important component in the transaction between the manufacturer and buyer of steel products such as plates, bars and strips.
