EN10216-1 is a European standard, a seamless steel pipe standard. It stipulates the manufacturing and inspection methods of seamless steel pipes working at high temperatures, and is mainly used in high-temperature and high-pressure fields such as petroleum, chemical industry, and power stations. In addition, seamless steel pipes under the EN10216-1 standard are also used in boiler water pipes, smoke pipes, superheater pipes, air preheating pipes, etc. This standard has detailed regulations on the chemical composition, mechanical properties, dimensional tolerances, etc. of steel pipes to ensure that the quality and performance of steel pipes meet the standard requirements.
Generally speaking, the chemical compositions specified in the EN 10216-1 standard mainly include carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements, as well as some other alloys that may exist Elements, such as chromium (Cr), molybdenum (Mo), etc.
| Carbon (C) | Silicon (Si) | Manganese (Mn) | Phosphorus(P) | sulfur (S) |
| ≤0.17% ~ 0.30% | ≥ 0.55% | 0.40% ~1.60% | ≤0.035%. | ≤0.035% |
During the production process, seamless steel pipes also need to go through a series of heat treatment and inspection processes, including heat treatment, straightening, cutting, hydrostatic testing, non-destructive testing, etc.
The characteristics of the EN10216-1 standard are mainly reflected in the following aspects:
1. Seamless steel pipe standard: EN10216-1 has higher strength and better sealing performance, so it has wider applications in high pressure, high temperature and other environments.
2. High temperature working performance: This standard pays special attention to the working performance of seamless steel pipes at high temperatures. The standard stipulates the chemical composition, mechanical properties and other requirements of steel pipes at high temperatures to ensure that steel pipes can still maintain stable performance in high temperature environments.
3. Strict quality control: The EN10216-1 standard stipulates in detail the manufacturing and inspection methods of seamless steel pipes, including requirements for chemical composition, mechanical properties, dimensional tolerances, surface quality, etc. of steel pipes. These regulations ensure that the quality and performance of steel pipes meet standard requirements.
4. Various specifications and materials: Seamless steel pipes under the EN10216-1 standard have a variety of specifications and materials to meet the needs of different customers. The specifications and materials of these steel pipes can be customized to meet specific application requirements.
Seamless steel pipes under the N10216-1 standard are mainly used in the following areas: in the extraction, transportation and storage of oil and natural gas. It is used to transport various corrosive liquids and gases in the chemical production process. Power station: used to transport media such as steam, water and hot oil. In boiler manufacturing, it is used as water pipes, smoke pipes, superheater pipes and air preheating pipes, etc. Used in other high temperature and high pressure fields, such as shipbuilding, aviation industry, etc.
