EN 10208-1 Standard: Technical Delivery Conditions for Steel Pipes for Combustible Fluids (Class A)
Purpose and Scope of EN 10208-1
The European standard EN 10208-1 establishes current technical requirements for the production and supply of seamless and welded steel pipes intended for onshore transportation systems for combustible fluids, including gas distribution networks. This specification focuses on general-purpose pipelines where operational loads are lower than those specified in the EN 10208-2 standard. EV Group China provides supplies of pipes that fully comply with the quality parameters set out in the standard.
| Steel Grade | EN Number |
|---|---|
| L210GA | 1.0319 |
| L235GA | 1.0458 |
| L245GA | 1.0459 |
| L290GA | 1.0483 |
| L360GA | 1.0499 |
Please note: Pipeline systems used in the oil and gas industry are governed by the international standard ISO 3183. API 5L requirements may also be applied as a supplement or alternative if specific project conditions exist. This standard does not apply to cast steel products.
EN 10208-2 Standard: High-Strength Steel Pipes for Gas Supply (Class B)
Technical Requirements and Specifics of EN 10208-2
The EN 10208-2 standard regulates higher requirements for quality, mechanical properties, and testing methods for seamless and welded pipes for onshore pipeline systems. Compared to Class A, this standard ensures higher reliability when operating under challenging conditions. Experts at EV Group China recommend selecting the pipe class based on an analysis of the operating environment properties, design standards, and operational risks.
