Compliance: EN 10217-7 Technical Condition 2 (TC2) for 1.4404 Pipes
The European standard EN 10217-7 specifies the technical delivery conditions for welded tubes made of stainless steel for pressure purposes. Given the corrosive service of 316L, the **1.4404 pipes Manufacturer** production is almost always finalized with the most stringent level of testing and certification.
Technical Condition 2 (TC2) - High Integrity
This is the most common and stringent requirement for critical pressure applications. All weld seams must undergo Non-Destructive Testing (NDT).
- Non-Destructive Testing (NDT): Mandatory weld seam testing (e.g., Eddy Current, Ultrasonic, or Radiographic) is required along the entire length of the weld.
- Testing: Requires Hydrostatic or Eddy Current testing.
- Documentation: Full 3.1 or 3.2 Inspection Certificate is required (TÜV, Lloyd's, DNV, etc.).
- Applications: Pharmaceutical, Food & Beverage, and high-pressure chemical systems.
Technical Condition 1 (TC1) - General Use
Suitable for less critical applications where the full cost and time of NDT are not justified.
- Non-Destructive Testing (NDT): Not mandatory unless specified by the purchaser.
- Testing: Requires flattening or flanging test and a leak tightness test.
- Documentation: 2.2 or 3.1 Inspection Certificate.
- Applications: Structural tubing, low-pressure conveyance, and non-critical components.
Grade 1.4404 (X2CrNiMo17-12-2 / TP316L) Chemical Composition & Key Properties
The EN 1.4404 grade is the low-carbon version of 316, providing superior weldability without compromising the critical Molybdenum-enhanced corrosion resistance. We are a reliable 1.4404 pipes Supplier and X2CrNiMo17-12-2 pipes Supplier globally.

Key Properties of 1.4404 (316L) Pipes
- Weld Decay Immunity: Low carbon content (max 0.03%) prevents carbide precipitation, allowing welding without post-weld solution annealing.
- Corrosion Resistance: Excellent resistance to pitting and crevice corrosion due to Molybdenum content (Mo).
- Dual Certification: Our stock is often dual-certified 1.4401/1.4404, satisfying material requirements for both standards.
- Applications: Widely used for highly corrosive liquid transport, processing equipment, and heat exchangers.

EN 10217-7 Grade 1.4404 Pipes — Frequently Asked Questions
Find answers to common questions about the EN 10217-7 standard, the TP316L pipe price, and low-carbon Molybdenum-enhanced stainless steel.
The very low carbon content (max 0.03%) in 1.4404 prevents sensitization (chromium carbide precipitation) during welding. This allows the pipe to be used in severely corrosive environments in the as-welded condition, making it the preferred choice for welded pipe systems.
The EN 1.4404 grade specifies a Molybdenum content typically between 2.0% and 3.0%. This Mo content is identical to 1.4401, providing the same high resistance to pitting and crevice corrosion.
Yes, 316L offers good corrosion resistance at high temperatures, but due to its low carbon content, it has slightly lower creep and stress-rupture properties than 316 (1.4401) at very high temperatures. For critical high-temperature structural integrity, the standard 1.4401 or stabilized grades like 1.4541 (321) may be preferred.
Yes, we also supply seamless pipes and tubes in the same grade (1.4404/316L) certified to EN 10216-5 and ASTM/ASME standards for seamless pressure applications where welded material is specifically prohibited.
