EN10253-4 is a European standard that describes the specifications for pipe fittings, including reducing tees, used in pipes for the transport of liquids and gases under pressure.
EN10253-4 reducing tees are pipe fittings that allow for the connection of three pipes of different sizes in a T-shaped configuration. These fittings are designed to allow for a reduction in pipe size while maintaining the flow of the fluid through the system. EN10253-4 reducing tees are manufactured in compliance with the EN10253-4 standard and are available in a range of materials, sizes, and designs to meet various industrial applications.
EN10253-4 Reducing 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.
EN10253-4 reducing tees are available in two designs:
Seamless reducing tees: These tees are manufactured from a single piece of material and do not have any welds or joints.
Welded reducing tees: These tees are manufactured by welding together three pipes of different sizes in a T-shaped configuration.
EN10253-4 Tees are used in a variety of industries and applications including:
Oil and gas industry
Installation and Maintenance:
EN10253-4 reducing tees should be installed and maintained in accordance with the manufacturer’s instructions to ensure safety and reliability. It is important to select the correct type of reducing tee for the specific application and to follow proper installation procedures, including the use of appropriate tools and equipment.
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.
