Chemical Requirement

The EN 10217 Carbon Steel Pipes from UNIASEN are manufactured to meet specific chemical requirements. This ensures that the pipes possess the necessary properties for strength, durability, and corrosion resistance. The chemical composition of the steel includes elements such as carbon, manganese, phosphorus, sulfur, and silicon. Each of these elements contributes to the overall performance of the pipe. For instance, carbon enhances the strength of the steel, while manganese improves its toughness. We strictly monitor the chemical composition of our pipes to ensure that they meet the highest standards of quality and performance.

b Elements not included in this Table shall not be intentionally added to the steel without the agreement of the purchaser, except for elements which may be added for finishing the cast. All appropriate measures shall be taken to prevent the addition of undesirable elements from scrap or other materials used in the steel making process.
b The content of these elements need not be reported unless intentionally added to the cast.
c Option 3: In order to facilitate subsequent forming operation, an agreed maximum copper content lower than indicated and an agreed specified maximum tin content shall apply.
d This requirement is not applicable provided the steel contains a sufficient amount of other nitrogen binding elements, which shall be reported.

Mechanical Requirement

The mechanical requirements of our EN 10217 Carbon Steel Pipes are designed to ensure their strength, durability, and performance. These requirements include properties such as tensile strength, yield strength, elongation, and impact resistance. Our pipes undergo rigorous testing to ensure that they meet these requirements, providing you with a product that you can trust. Whether you’re using our pipes for a high-pressure application or a low-temperature environment, you can be confident that they will perform as expected.
