In modern acid production, where corrosive environments are constant and extreme, choosing the right pipeline material is critical for maintaining safety, minimizing downtime, and extending service life. Compared to traditional stainless steel, ASTM B338 titanium pipes offer up to 10 times longer lifespan, making them the preferred solution for hydrochloric acid, sulfuric acid, nitric acid, and mixed acid systems.   Jiangsu Hongbao Group specializes in the production of high-performance ASTM B338 titanium pipes, designed to meet the demands of the chemical industry. Our pipes are manufactured with high-purity titanium grades such as Gr2, Gr7, and Gr12, which exhibit superior corrosion resistance in highly acidic and oxidizing media. These materials are especially effective in preventing pitting, crevice corrosion, and stress corrosion cracking—common failures in steel pipelines used in acid environments.   With outer diameters ranging from 6mm to 270mm, wall thicknesses from 0.5mm to 22mm, and lengths up to 18 meters, our seamless titanium pipes are engineered to deliver unmatched durability and dimensional stability. Advanced production facilities—such as 1500T hydraulic presses, vacuum annealing furnaces, and high-precision rolling machines—ensure that every pipe meets strict international quality standards, including ASTM B338 and ASME SB338.   Our titanium pipes are already in widespread use in acid storage systems, acid circulation pipelines, evaporators, and heat exchangers in chemical plants worldwide. With PED, DNV, and Lloyd’s certifications, we are a trusted supplier to many leading chemical equipment manufacturers and EPC contractors.   By switching from steel to ASTM B338 titanium pipes, acid producers can dramatically reduce maintenance frequency, avoid costly plant shutdowns, and achieve lower total cost of ownership over time.

In chlor-alkali production, where highly corrosive media such as chlorine gas, hydrochloric acid, and sodium hydroxide are involved, material selection plays a critical role in ensuring operational safety and long-term stability. Seamless titanium tubes have emerged as the optimal solution for piping and heat exchange systems in these challenging environments due to their superior corrosion resistance, high strength-to-weight ratio, and long service life.   At Jiangsu Hongbao Group, we specialize in manufacturing high-quality seamless titanium and titanium alloy tubes, engineered specifically for demanding chemical applications. Our products conform to ASTM B338, ASTM B861, ASME SB338, and SB861 standards, and are available in Gr2, Gr7, Gr12, and other corrosion-resistant titanium grades ideal for chlor-alkali plants.   With an outer diameter range from 6mm to 270mm, wall thickness from 0.5mm to 22mm, and maximum length up to 18 meters, our seamless titanium tubes are manufactured using state-of-the-art equipment such as 1250T extrusion presses, vacuum annealing furnaces, and automated hydraulic pressure testers. These precision-controlled processes ensure exceptional dimensional accuracy, smooth internal surfaces, and outstanding weldability—all essential for the harsh chemical environments in chlor-alkali systems.   In addition to PED, DNV, and Lloyd’s Register certifications, we provide third-party inspection reports (SGS, TÜV, etc.) to meet the strict quality requirements of global clients. Our seamless titanium tubes are already widely used in electrolytic cells, brine heaters, heat exchangers, and chemical transport pipelines within the chlor-alkali industry.   Choosing Jiangsu Hongbao means choosing a reliable long-term partner committed to precision manufacturing, corrosion resistance, and global service. If you're seeking an efficient, maintenance-free, and corrosion-proof solution for your chlor-alkali project, our titanium seamless tubes offer the ultimate performance.

Titanium tubes are widely used in processing strong corrosive chemical media due to their outstanding corrosion resistance and long-term stability, even under elevated temperatures and concentrations. Common suitable media include: Sulfuric Acid (H₂SO₄): Excellent resistance across a wide range of concentrations and temperatures; ideal for acid concentration units and condensers. Hydrochloric Acid (HCl): Good corrosion resistance in dilute to moderate concentrations; used in recovery and cooling systems. Nitric Acid (HNO₃): Forms a protective oxide film in concentrated nitric acid, providing superior corrosion resistance. Phosphoric Acid (H₃PO₄): Titanium tubes are widely used in phosphate fertilizer and wet-process phosphoric acid systems. Organic Acids (e.g., Formic, Acetic, Oxalic Acid): Titanium exhibits excellent stability against various organic acids used in fine chemical production. Chlorinated Organics and Chlorine Gas: Titanium shows high resistance to chlorine-induced stress corrosion and is suitable for chlorination processes. Alkalis (e.g., NaOH, KOH): Titanium provides moderate resistance in some alkaline environments, applicable in selective caustic heat exchange systems. These properties make titanium tubing an ideal choice for chemical plants requiring high reliability, corrosion resistance, and long service life.

Titanium tubes are widely used across multiple industries due to their exceptional corrosion resistance, high strength-to-weight ratio, and stable thermal performance. Key applications include: Chemical Industry: Used in heat exchangers, condensers, and reactor linings handling aggressive media such as sulfuric acid, hydrochloric acid, chlor-alkali, and organic acids. Power Generation: Applied in power plant condensers where seawater or high-chloride cooling water is used, helping prevent corrosion and fouling. Marine Engineering: Ideal for desalination plants, offshore platform cooling systems, and underwater transport systems due to their excellent seawater corrosion resistance. Pharmaceutical & Food Processing: Suitable for hygienic applications in steam heating, cooling, and transfer systems requiring non-toxic, corrosion-resistant piping. Environmental Protection Equipment: Installed in gas and liquid waste treatment heat exchange systems to ensure long-term durability and reduced maintenance. Petrochemical & Natural Gas: Employed in condensers, reboilers, and heaters handling sulfur-containing or acidic media.

When choosing titanium tubes for applications in chemical processing, seawater systems, or power generation, it is essential to match the tube grade and dimensions to the specific working conditions such as corrosive medium, temperature, pressure, and installation environment. Here are the key selection guidelines: Select Material Grade Based on Corrosive Media: Grade 2 (Commercially Pure Titanium): Suitable for most mild acids, seawater, and moist chlorine gas; cost-effective. Grade 12: Alloyed with molybdenum and nickel, offering enhanced corrosion resistance, ideal for hot concentrated sulfuric acid or reducing media. Determine Material Stability by Temperature Range: Grade 2 is typically used in ambient to medium-temperature conditions (≤300°C). For higher temperatures or thermal cycling, consider Grade 7 or other titanium alloys. Select Wall Thickness Based on Operating Pressure: Low-pressure systems: 0.5–1.0mm wall thickness is sufficient. High-pressure systems: Choose thicker walls (≥1.5mm) for mechanical strength. Decide Length and Outer Diameter Based on Equipment Layout: Common OD range: 6–60mm. Lengths can be customized up to 18 meters to reduce weld joints and improve heat exchange efficiency. Consider Surface Treatments like Vacuum Annealing or Polishing: Applications in chemical or pharmaceutical industries may require polished internal/external surfaces to prevent contamination and fouling. Ensure Compliance with Standards (e.g., ASTM B338): Clarify if international standards apply to meet project quality requirements and facilitate global sourcing. By aligning titanium tube specifications with actual operating conditions, users can ensure long-term reliability, corrosion resistance, and cost-efficiency in demanding industrial environments.
