Flue Gas Desulfurization (FGD) systems are a critical part of modern fossil fuel power plants, designed to remove sulfur dioxide (SO₂) from exhaust gases and reduce environmental pollution. One of the most important components in wet FGD systems is the spray pipe, which continuously delivers absorbent slurry to scrubbers. Due to the extremely corrosive environment created by acidic flue gas and slurry mixtures, titanium spray pipes have become the preferred choice for long-term reliability and cost efficiency.
At Jiangsu Hongbao Group Co., Ltd., we specialize in manufacturing titanium and titanium alloy pipes for FGD spray applications. Our products are engineered to meet the most demanding operational requirements, with superior resistance to acid corrosion, chloride attack, and abrasion from slurry particles. They are manufactured according to ASTM B338, ASTM B861, ASME SB338, and SB861 standards, with available grades including Gr2, Gr7, and Gr12, all proven to perform exceptionally in aggressive FGD environments.
Our titanium FGD spray pipes are available in outer diameters from 6mm to 270mm, wall thickness from 0.5mm to 22mm, and lengths up to 18 meters. We utilize advanced production equipment including 2T vacuum consumable electrode furnaces, 1250T extrusion presses, vacuum annealing furnaces, and automatic hydraulic pressure testing systems to ensure precise dimensions, excellent mechanical properties, and smooth internal surfaces for optimal flow performance.
Compared with traditional stainless steel, titanium spray pipes offer significantly longer service life, reduced maintenance requirements, and better resistance to scaling, ensuring uninterrupted operation and lower lifecycle costs for power plants. Many of our titanium spray pipes are already installed in coal-fired and oil-fired power plants worldwide, operating reliably under continuous high-load conditions.
With certifications from PED, DNV, and Lloyd’s Register, and the option for third-party inspections (SGS, TÜV, etc.), we guarantee quality and performance that meet international standards. Our engineering team also offers customization services, including pipe bending, flange integration, and pre-welding, to simplify installation at the plant site.
