Hastelloy C-4 Tube for Corrosion-Resistant Pollution Control Systems
Our Hastelloy C-4 tubes are the perfect fit for corrosion-resistant pollution control systems. Made from a nickel-chromium-molybdenum alloy, these tubes are built to handle acidic gases, wet environments, and high temperatures without breaking a sweat. They’re ideal for scrubbers, ducts, and piping in systems like flue gas desulfurization (FGD) and waste incineration. Easy to weld and form, they resist pitting, crevice corrosion, and stress corrosion cracking. Whether it’s hydrochloric, sulfuric, or nitric acids, our tubes keep your systems running smoothly.
The pollution control industry is on the rise, driven by global environmental regulations cracking down on emissions. Power plants, chemical facilities, and waste treatment operations are investing heavily in corrosion-resistant materials to meet these standards. The push for cleaner air and water is fueling demand for durable tubing in FGD systems, incinerators, and wet scrubbers. Emerging markets are ramping up infrastructure, while developed regions focus on retrofitting aging systems. Trends point to materials that offer long lifespans and low maintenance, and our Hastelloy C-4 tubes are leading the pack in this growing market.

Parameter | Hastelloy C-4 Tubes | Other Nickel Alloys | Stainless Steel |
|---|---|---|---|
Acidic Gas Resistance | Outstanding in wet, acidic pollution control | Good, but less consistent in mixed corrosives | Poor, corrodes in acidic and chloride settings |
Temperature Resilience | Reliable at high temperatures | Varies, some alloys weaken at extreme heat | Limited, degrades under high temps |
Weldability | Excellent, no corrosion in weld zones | Good, some require special techniques | Moderate, weld zones prone to corrosion |
Pitting/Crevice Corrosion | Superior resistance in chloride environments | Moderate, depends on alloy | Poor, highly vulnerable to pitting |
Oxidizing Media Resistance | Strong in both oxidizing and reducing conditions | Varies, some struggle with oxidizing media | Better in oxidizing, weak in reducing acids |
Durability | Extremely durable, long service life | Moderate to high, depends on alloy | Moderate, shorter lifespan in harsh environments |
Fabrication Ease | Easy to weld and form | Moderate, some alloys harder to work with | Easy, but corrosion limits applications |
Cost-Effectiveness | Higher initial cost, long-term savings | Varies, some cheaper but less durable | Low cost, frequent replacements needed |
