EN 10217-1 Welded Steel Tubes for Pressure Purposes

EN 10217-1 is a welded steel pipe standard developed by the European Committee for Standardization, which specifically regulates the technical requirements of non-alloy carbon steel welded round pipes used at room temperature.

The standard covers three strength grades: P195, P235, and P265. Each is divided into two inspection grades, TR1 and TR2. TR2 has stricter inspection requirements.

We are a Chinese manufacturer of high-quality carbon steel pipes. We strictly follow the standard for chemical composition, mechanical properties, hydrostatic testing, and non-destructive testing. The manufacturing process can be ERW, SAW, or LSAW. The products can be in a welded or normalized state.

This pipe is widely used in pressure vessels, industrial piping, fire protection, and water supply and drainage systems.

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.
