EN 10216 Seamless Steel Tubes supplier


EN 10216 is a standard which covers steel grade P235TR2, which are well suited for pressure applications. Furthermore, European Standard EN 10216-1 specifies the technical delivery conditions for two qualities steels i.e. en 10216-1 p235tr1 and TR2. Both these steel qualities are seamless tubes produced with a circular cross-section. This standard also mentions specific properties at room temperature from products, for instance, EN 10216-1 Grade P235TR2 Alloy Steel Seamless Tubes manufactured from a quality of non-alloy steel.

 EN 10216-1 Pipe

 

While steels belonging to quality TR1 are used for applications involving the conveyance of different media, whereas steels under quality en 10216-1 p265tr2 are intended for use in systems for both pressure equipment and pipelines. Similar to most English standards, there are different designations that describe the use of the said steel grade.  While the letter P suggests that the EN 10216 Seamless Steel Tubes is to be used for pressure purposes, the number 235 or 265 makes a mention of its minimum yield strength in N/mm2. The letters T designates a tube, whereas R is the designation for non alloy steels meant for ambient or room temperature use, with either number 1 or 2 indicating the quality of the en 10216-1 material.
