EN10253-4 is a European standard that describes the specifications for pipe fittings, including tees (or T-pieces), used in pipes for the transport of liquids and gases under pressure.
EN10253-4 Tees are fittings used to split a pipeline into two or more branches. They are designed to be installed in any orientation and are suitable for various applications, such as the distribution of liquids and gases in a piping system.
Material and dimensions
EN10253-4 Tees are available in a variety of materials including steel, stainless steel and carbon steel. The choice of material depends on the specific application and the conditions under which the attachment is used. EN10253-4.
Material | Designation |
---|---|
Carbon steel | S235, P235TR1/2, P265TR1/2, ASTM A234 WPB |
Stainless steel | 1.4301, 1.4306, 1.4401, 1.4571, 1.4541, 1.4828, ASTM A403 WP304/304L, WP316/316L, WP321, WP347 |

Design
EN10253-4 Tees are designed according to the EN 10253-4 standard and are available in different designs such as welded tees and seamless tees. Welded tees are made by welding three pipes together in the shape of a T. Seamless tees are made from one piece of material and have no weld seam.
EN10253-4 T-pieces are available in different pressure ratings, ranging from PN 6 to PN 400. The pressure rating depends on the application and the conditions under which the fitting is used.
Dimensions:
EN10253-4 Tees are available in different sizes ranging from DN 6 to DN 1200. The dimensions are indicated by the nominal diameter (DN), the outside diameter (OD) and the wall thickness (WT).
Design:
EN10253-4 Tees are available in a variety of designs including:
Welded Tees: These are made by welding three pipes together in the shape of a T.
Seamless T-pieces: These are made from one piece of material and have no weld seam.
Pressure class:
EN10253-4 T-pieces are available in different pressure ratings, ranging from PN 6 to PN 400. The pressure rating depends on the application and the conditions under which the fitting is used.
Certification and quality
EN10253-4 T-pieces must be produced according to the standards and regulations laid down in the EN 10253-4 standard. This standard specifies the material properties, dimensions, tolerances, wall thickness and quality requirements for tees.
EN10253-4 Tees must be supplied with a Declaration of Conformity and must be tested for quality and performance. Tests include hydrostatic pressure testing and ultrasonic testing to verify material integrity and welds.
Applications
EN10253-4 Tees are used in a wide range of applications including the oil and gas, chemical, food and pharmaceutical industries. They are used to split a pipeline into two or more branches and are suitable for transporting various liquids and gases.
Conclusion
EN10253-4 Tees are important fittings used in piping systems for transporting various liquids and gases. They are available in different materials, sizes and designs and must be produced according to EN 10253-4 standards and regulations. EN10253-4 Tees are used in a variety of industries and applications and must be supplied with a Declaration of Conformity and tested for quality and performance. It is important to ensure that the correct EN10253-4 tee type is selected for the specific application and to follow the manufacturer’s installation and maintenance instructions to ensure safety and reliability.
