Titanium Pipe Tube for Chemical Processing: Corrosion Resistance Guide
Introduction
For buyers selecting Titanium Pipe Tube for Chemical Processing, the main decision points are corrosion media, chloride concentration, temperature, pressure, flow condition, welding requirement, titanium grade, ASTM / ASME standard, wall thickness, surface condition, EN 10204 3.1 MTC, PMI testing, hydrostatic testing, UT or eddy current testing, heat number control, export packaging and delivery capability. Titanium pipe and tube are widely used in chemical processing because titanium forms a stable oxide film that provides excellent resistance to seawater, chlorides, wet chlorine, nitric acid, oxidizing environments and many industrial chemicals where stainless steel may suffer pitting, crevice corrosion or stress corrosion cracking.
Titanium pipe and titanium tube are commonly used in heat exchangers, condensers, evaporators, reactors, pressure vessels, chemical transfer lines, chlor-alkali equipment, desalination systems, acid processing equipment and offshore chemical systems. Grade 2 titanium is the most widely used industrial grade for chemical processing due to its balance of corrosion resistance, weldability and cost. Grade 7 is selected when improved corrosion resistance is needed in selected reducing acid environments, while Grade 12 provides higher strength and good corrosion performance for more demanding process conditions.

Limitations and Buyer Mistakes
Titanium is not suitable for every chemical environment. It performs very well in many oxidizing and chloride-containing media, but it may not be suitable for some strong reducing acids, dry chlorine, hydrofluoric acid or high-temperature conditions without careful engineering review. Buyers should not select titanium only by grade name; they should provide chemical media, concentration, temperature, pressure and operating conditions before final material selection.
Common buyer mistakes include using Grade 2 where Grade 7 is required, selecting welded pipe without checking weld quality, ordering heat exchanger tube without confirming ASTM B338, ignoring hydrostatic or eddy current testing requirements, failing to specify wall thickness tolerance, and accepting material without matching heat number and MTC. For critical chemical projects, third-party inspection and pre-shipment documentation review are strongly recommended.
Surface Finish, Fabrication and Export Packaging
Titanium pipe and tube can be supplied with pickled, bright, polished, cleaned, sandblasted or custom surface condition. For chemical processing, clean surface condition is important because contamination can affect corrosion performance and welding quality. For heat exchanger tubes, inside and outside surface quality, straightness, ovality and wall thickness consistency should be controlled carefully.
Fabrication services may include cutting, beveling, bending, U-bending, cleaning, polishing, end capping, marking and customized length supply. Export packaging should protect titanium pipe and tube from scratches, moisture, contamination and deformation. Common packaging includes plastic wrapping, end caps, wooden cases, wooden pallets, waterproof paper, tube bundles, steel strip binding and clear heat number labels.
