Compliance: EN 10217-7 Technical Condition 2 (TC2) for 1.4571 Pipes
The European standard EN 10217-7 specifies the technical delivery conditions for welded tubes made of stainless steel for pressure purposes. Due to the high-stakes applications of 316Ti, the **1.4571 pipes Manufacturer** production is virtually always certified to the most stringent level.
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: High-temperature chemical, petrochemical, and power generation 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 1.4571 (X6CrNiMoTi17-12-2 / TP316Ti) Chemical Composition & Key Properties
The EN 1.4571 grade achieves its high performance by adding Titanium (Ti) to the standard Molybdenum (Mo) containing 316. This provides a truly stabilized 316 for high-heat welding. We are a reliable 1.4571 pipes Supplier and X6CrNiMoTi17-12-2 pipes Supplier globally.

Key Properties of 1.4571 (316Ti) Pipes
- Dual-Protection: Molybdenum for pitting resistance in chlorides + Titanium for sensitization resistance at high heat.
- High-Temp Weldability: Maintains full corrosion resistance even after welding and long-term exposure in the critical sensitization range (425°C - 815°C).
- Applications: Excellent for chemical and petrochemical equipment where heat and corrosive fluids combine, such as heat exchanger tubes.
- Alternative Grades: Often specified as an upgrade to 1.4404 (316L) for high-temperature service.

EN 10217-7 Grade 1.4571 Pipes — Frequently Asked Questions
Find answers to common questions about the EN 10217-7 standard, the TP316Ti pipe price, and Molybdenum-Titanium stabilization.
316Ti (1.4571) is stabilized with Titanium, which locks up carbon, preventing sensitization (weld decay) during prolonged high-temperature exposure (425°C - 815°C) that would eventually affect 316L. 316Ti maintains better creep strength and full corrosion resistance in this critical temperature range.
The primary applications are in highly corrosive industrial environments, chemical and petrochemical plants, and offshore platforms that operate under high heat. Examples include heat exchangers, furnace components, and process equipment in the pulp and paper or textile industries.
Both 1.4571 (316Ti) and 1.4541 (321) are Titanium-stabilized. The key difference is that 1.4571 contains Molybdenum, giving it superior resistance to pitting and crevice corrosion in chloride and sulfuric acid environments compared to 1.4541.
Yes, we supply seamless tubes in 1.4571 (TP316Ti) certified to EN 10216-5 and ASTM/ASME standards for heat exchanger and boiler applications where seamless tubing is specified to meet thermal and pressure demands.
