Nickel 201 Seamless Tube Nickel Seamless Pipe UNS N02201
Nickel alloy pipe is mainly composed of nickel (Ni), and usually contains chromium (Cr), iron (Fe), molybdenum (Mo), copper (Cu), titanium (Ti) and other elements. The addition of these elements is aimed at improving the specific properties of the alloy, such as corrosion resistance, strength and high temperature resistance.
1. DINGSCO focuses on the production of nickel alloys, we are committed to providing high-performance alloy materials for global petrochemical equipment.
2. DINGSCO has three complete workshops for smelting, forging and processing.
3. Passed LR ISO:9001, PED2014 68, EU, API-6A, API-20B and NORSOK and other international high-quality system certifications
4. DINGSCO has introduced international advanced intelligent 35MN extrusion molding equipment for special nickel alloys to manufacture special nickel alloy pipes and profiles.
The extrusion molding products are mainly used in medical and new energy (solar energy, hydrogen energy) ultra-clean fluid equipment (such as high-purity 316LMD, high-purity 304L), petrochemical ultra-high temperature and ultra-high pressure equipment (such as UNS N06617), ultra-high temperature and ultra-pressure support special-shaped parts for artificial suns (UNS N07718), super-supercritical ultra-pure NiCrFe alloy parts in gas turbines, super ferrite (29-4C) and super-super duplex steel (S32707) parts in seawater desalination devices, nuclear reactor nuclear parts (UNS N06690), rocket launcher fluid parts (UNS N07718/UNS N06002), etc.
Special nickel alloy 35MN extrusion molding equipment will become an important support for DINGSCO's special materials products with higher-end performance, more special uses and more cutting-edge services, and better provide high-performance alloy materials for global petrochemical equipment.
