|---|---|
| Yield Strength (MPa) | ≥ 245 |
| Tensile Strength (MPa) | ≥ 400 |
| Elongation (%) | ≥ 20 |
| Hardness (HB) | ≤ 200 |
Steel Grade
The steel grades specified under GOST 633-80 include various classifications based on their chemical composition and mechanical properties. Common grades include:
- DKE
- DKELMR
- NKM
- NKB
Application
GOST 633-80 oil steel pipes are primarily used in:
- Oil and Gas Extraction: Essential for drilling operations and transporting crude oil.
- Pipeline Construction: Used in the construction of pipelines for transporting oil and gas.
- Refinery Operations: Suitable for various processes within oil refineries.
Possible Alternative Grades
While GOST 633-80 specifies certain grades, there are alternative grades that can be considered based on specific requirements:
- API 5L: Commonly used for pipeline applications.
- ASTM A106: Suitable for high-temperature service.
- ASTM A53: Often used for structural and pressure applications.
