PED Certified GH3030 Heat Exchanger Tube Manufacturer
PED Certified GH3030 Heat Exchanger Tube Manufacturer
PED-certified GH3030 heat exchanger tubes are high-temperature, corrosion-resistant nickel-based alloy components designed specifically for pressure equipment, particularly suitable for the European market where compliance with the Pressure Equipment Directive 2014/68/EU (PED) is required. GH3030 (often labeled Gh3030 or similar NiCr20Ti) is a solid solution-strengthened nickel-based alloy renowned for its strength up to 850°C and its oxidation resistance.
What are the components of GH3030?
GH3030 is a solid solution strengthened high-temperature alloy, mainly composed of nickel (Ni) and chromium (Cr), with a simple chemical composition. Its typical ratio is 80% nickel and 20% chromium.
1. Chemical composition of GH3030 pipe
| Element | Nickel (Ni) | Chromium (Cr) | Titanium (Ti) | Iron (Fe) | Silicon (Si) |
| Percentage | Balance (≥75.0) | 19.0 - 22.0 | 0.15 - 0.35 | ≤ 1.50 | ≤ 0.80 |
2. Mechanical properties of GH3030 pipe (at room temperature)
Tensile Strength (Rm): ≥ 685 MPa (100 ksi)
Yield Strength (Rp 0.2): ≥ 275 MPa (40 ksi)
Elongation (A5): ≥ 35% (Crucial for expanding and tube-to-sheet welding)

FAQ
Q1: Can your GH3030 tubes replace Nimonic 75 in German thermal projects?
A: Yes. GH3030 is the direct equivalent to the European standard W.Nr. 2.4951 (NiCr20Ti) and the British Nimonic 75. We have a proven track record of supplying these tubes to major energy projects in Germany, ensuring 100% technical and regulatory compatibility.
Q2: What is the maximum length you can supply for heat exchanger bundles?
A: As a specialized superalloy tube manufacturer, we can produce straight seamless tubes up to 12 meters in length, perfect for large-scale boiler and heat exchanger bundles. We also offer U-bending services according to your drawings.
Q3: How do you handle export logistics for EU countries?
A: We have decades of experience in wholesale supply to Europe. We manage all export documentation, seaworthy packaging in reinforced plywood cases, and offer DDP or CIF terms to major ports like Hamburg, Genoa, and Marseille.
