Products Description
Zr702 pipe fitting refers to a component made from Zr702, which is a zirconium alloy known for its excellent corrosion resistance, high strength, and good thermal conductivity. Zr702, also known as Grade 702 or the ISO grade R50400, is a specific composition of titanium that contains approximately 7% molybdenum, 2% zirconium, and other alloying elements like iron and aluminum.
Features of Zr702 pipe fitting
- Resistance to corrosion: Properties of Zr702 alloy make it suitable for marine, chemical and petrochemical industries because it does sustain considerable amount of corrosion in seawater and in acidic and other hazardous environments.
- Strength: Increased strength to weight ratio of Zr702 pipe fitting results in reduced cost and reduced weight since thinner walls can be employed when compared to conventional materials.
- Conductivity: Zr702 pipe fitting has adequate thermal conductivity which is vital for heat exchangers.
- Plasticity: Zr702 pipe fitting is completely malleable which is ideal for other processes of manufacturing pipe fittings.
Applications of Zr702 Pipe Fitting
Chemical Processing: In the pipe and fitting industry Zr702 chemical resistant pipe fittings are deployed in the chemical industry for processing corrosive chemicals and acidic solutions.
Marine Applications: Oftentimes in shipconstructing and offshore construction, they are used in piping systems in saltwater integraded regions.
Power Generation: Due to the corrosion resistance and heat tolerance of the alloy, the material is used in power plants in steam generators or exchangers of heat.
Pulp and Paper Industry: Zr702 pipe fittings, resistant to corrosive elements and used in processing devices, are employed in the pulp and paper industry, where acidic or caustic substances are used.
Types of Zr702 Pipe Fitting
- Elbows: Functions to change the directional flow of a pipe.
- Tees: Separate the flow into two or three distinct pipes.
- Wyes: Resemble tees but that permit smoother flow.
- Caps: Used to seal the termination of a pipe or to join pipes at various slopes.
- Flanges: Used for joining various pipes and other pieces of equipment.
- Valves: Used to govern the movement of liquids through the pipeline.

What is the delivery method?
A: Generally, we send cargo by UPS, DHL or FedEx. Also, we can send by sea to seaport or by air to the closest airport.
What is Zr702's composition?
A: Commercial purity zirconium (UNS R60702):
✓ Zr ≥99.2%
✓ Fe ≤0.2% (main impurity)
✓ Hf ≤4.5% (nuclear grade requires <100ppm)
Why choose Zr702 over stainless steel?
Key advantages:
• 10x better HCl resistance (up to 37% concentration)
• No pitting in chloride environments
• Maintains ductility at cryogenic temps
Nuclear industry applications?
Essential for:
Reactor coolant piping
Fuel rod cladding
Reprocessing equipment
(due to low neutron absorption: 0.18b)
Pressure rating standards?
Per ASME B31.3:
SCH40: 1500psi @ 300°C
SCH80: 2500psi @ 300°C
(Custom ratings available)
Welding requirements?
Must:
▸ Use ERZr2 filler wire
▸ Maintain argon shielding (front/back)
▸ Limit heat input to 35kJ/inch max
Surface finishes?
Standard:
• Mill finish (Ra 3.2μm)
• Pickled (removes oxide layer)
Special:
• Electropolished (Ra 0.8μm)
Cost comparison?
Approx. 3x 316L stainless steel
but lasts 5-8x longer in corrosive service
How to prevent contamination?
Critical precautions:
Dedicated carbon-free tools
Avoid grinding with SiC abrasives
Clean with alcohol (no chlorides)
