EN 10216-1 non alloy steel tubes
EN 10216-1 is a European standard that specifies the technical delivery conditions for two qualities of non-alloy steel tubes.
The tubes are seamless and have a circular cross section. They have specified room temperature properties and are suitable for pressure applications.
The two qualities are TR1 and TR2. The tubes are mainly used as boiler water tubes, smoke tubes, superheater tubes, and air preheater tubes.
The EN 10216 standard has five parts, each specifying the delivery conditions for alloy or non-alloy seamless steel tubes.
1. Quality and Specifications:
- EN 10216-1 defines two qualities of seamless tubes: TR1 and TR2.
- These tubes are made of non-alloy quality steel.
- The steel used in these tubes is fully killed, ensuring uniform properties.
2. Surface Treatment:
- The tubes are varnished on the outside to prevent rusting.
3. Applications:
- EN 10216-1 seamless steel tubes are used for various pressure purposes, including in the production of storage tanks made of heat-resistant steels used in boiler-making and tool-making.
4. Variants:
- The standard includes variants like P195TR1 and P265TR2, each with specified room temperature properties.
5. Use Cases:
- These tubes find applications in boiler water tubes, smoke tubes, superheater tubes, air preheater tubes, and more.
6. Uniform Tolerances:
- Cold Drawn Seamless Mechanical Tubing (CDS) is a type of EN 10216-1 tube known for its uniform tolerances, enhanced machinability, and increased strength.
7. Availability:
- Tubes conforming to EN 10216-1 can be supplied in various lengths, including random lengths.
This part of EN 10216 specifies the technical delivery conditions in two test categories for seamless tubes for circular cross section, with specified elevated temperature properties, made of non-alloy and alloy steel.
