Description

P235TR2 is a European standard for welded steel tubes used for pressure purposes. This standard is specified in EN 10217-1, which is a part of the EN 10217 series of standards for welded steel tubes for pressure purposes.

The "P" in P235TR2 stands for "pressure," indicating that this steel tube is intended for use in pressure applications. The number "235" in the designation refers to the minimum yield strength of the steel, which is 235 MPa. The letters "TR" indicate that the tube is a "tube reduced" product, which means that the outside diameter of the tube has been reduced by cold drawing or rolling.

The "2" in P235TR2 indicates that this is a steel tube with improved impact strength at low temperatures. This is achieved by using a different chemical composition than standard P235 tubes, which contains higher amounts of manganese and silicon.

EN 10217-1 specifies the technical delivery conditions for welded steel tubes for pressure purposes, including requirements for dimensions, tolerances, and testing. This standard applies to tubes with a circular cross-section and a wall thickness up to 40 mm.

The steel tube P235TR2 is commonly used in various industries, such as oil and gas, chemical, and power generation, for conveying fluids under pressure. It is also suitable for use in low-temperature applications, such as cryogenic storage and transportation.

Application

P235TR2 is a grade of welded steel tube specified in EN 10217-1 standard. This grade of steel tube is typically used for transporting fluids and gases at low to medium pressure, and is commonly used in industries such as oil and gas, chemical, and construction.

The application of P235TR2 welded steel tube depends on the specific requirements of the project. Some common applications of this grade of tube include:

  1. Transporting liquids and gases: P235TR2 tubes are commonly used for the transportation of fluids and gases at low to medium pressure. These tubes are often used in pipelines, for example, for transporting oil or gas.
  2. Construction: P235TR2 tubes can also be used in the construction industry for various applications such as structural supports, scaffolding, and handrails.
  3. Manufacturing: P235TR2 tubes can be used in the manufacturing industry for various applications such as machinery and equipment.
  4. Heat exchangers: P235TR2 tubes can be used in heat exchangers for transferring heat from one fluid to another.

It is important to note that the specific application of P235TR2 welded steel tube should be determined by a qualified engineer or designer based on the specific requirements of the project, including the pressure, temperature, and fluid or gas being transported. The proper installation and maintenance of the tube should also be ensured to ensure its proper functioning and longevity.
