Gr2 Titanium Pipe

Gr2 Titanium Pipe for Condensers, Evaporators and Heat Exchangers in Marine and Chemical Service

Chlorides turn up everywhere in marine and chemical plants. Surface condensers see them all the time. So do evaporators, and so do heat exchangers. Piping in those systems has to cope. Gr2 Titanium Pipe is supplied by Shaanxi Chuanghui Daye Metal Material Co., Ltd. What arrives is unalloyed, commercially pure (CP) titanium with an alpha-phase microstructure. Density measures 4.51 g/cm³. Yield strength bottoms out at 275 MPa. The minimum tensile strength is 345 MPa. Between pH 2 and pH 12, the titanium dioxide film stays intact. Water moving at up to 20 m/s leaves it alone. Sizes follow whatever you ask for.

What Is Grade 2 Titanium Pipe?

Grade 2 shows up in plenty of industrial jobs. Strength stays moderate. Ductility runs high, and the metal shapes without trouble. Grade 1 is softer than Grade 2. Grade 5 is harder, and parts made from it cost more. Grade 2 sits between the two. Aggressive media in fluid transport? It handles that well.

Stress corrosion cracking (SCC) is a common weak spot in 304 and 316L stainless steel. Chlorides set it off. Titanium does not have this problem. Pitting and crevice corrosion leave it alone too. Density comes to 4.51 g/cm³. Steel weighs more than that. That eases the load on piping supports and on structures.

Corrosion and Erosion Resistance

A TiO2 film covers the whole titanium surface. The film regrows after a scratch. That regrowth protects the pipe in chloride environments.

Seawater moving at up to 20 m/s doesn't wear the pipe down through erosion-corrosion. The water may sit still too. Even then, the pipe holds up against microbiologically influenced corrosion (MIC) and corrosion under insulation (CUI). Many other metals fail in both cases. Temperature changes how long the pipe really lasts. The medium and the operating conditions matter as well.

Applications of Gr2 Titanium Pipe

The main uses are surface condensers, this product, evaporators and heat exchangers. Three service areas are typical:

• Desalination and power generation: Heater tubes and condenser tubes in Multi-Stage Flash (MSF) and Reverse Osmosis (RO) plants are where pipee works. Hot brine and water with high chloride levels give it no trouble. Stainless steel often pits in that kind of water.
• Chlor-alkali chemical processing: This line carries wet chlorine gas. Hypochlorite solutions also go through it. The oxide layer holds only if the water content stays above 0.5%, so keep an eye on that number. Every process has its own limits, so check yours too.
• Offshore oil and gas fire water systems: Platforms use it in deluge systems and in ballast water piping. MIC and stagnant seawater corrosion do little damage to it. That cuts maintenance work in subsea and splash-zone areas.

Titanium Compared With Stainless Steel, Copper-Nickel and Steel

• Stainless steel 304/316L: Chlorides are present, yet titanium does not suffer SCC. Pitting will not start either. The same goes for crevice corrosion.
• Copper-nickel alloys: Seawater that moves fast does less erosion and corrosion damage to titanium.
• Steel piping: Titanium is lighter in weight. A lighter load then goes through the structure.

Fewer replacements can mean fewer shutdowns too. Whether that holds depends on how the system is run. Lifecycle cost may drop as well.

Be used in a wide range of industries.

Fabrication and Installation

Good cold formability shows up when elongation reaches ≥ 20%. Bending gets easier on site, and so does fit-up.

Two forms are available. One is pipe made to ASTM B861 with no seam. The other is welded pipe to ASTM B862. Where condenser and heat exchanger tubes are concerned, ASTM B338 is the standard that applies. After a specific standard? Say so in your inquiry. What we ship then lines up with your purchase order.

Purchasing and Customization

Sizes are made to your request. To quote Gr2 Titanium Pipe accurately, please send:

• Applicable standard (ASTM B338, B861 or B862)
• Seamless or welded type
• Outer diameter, wall thickness and length
• Quantity and service medium
• Any test certificate or inspection requirements

Packing depends on how long the pipes are and how much you order. The shipping route matters too. Send your delivery needs along with the inquiry.

Shaanxi Chuanghui Daye Metal Material Co., Ltd. is based in the Baoji High-tech Development Zone. Locals call this part of China the "Titanium Capital". More than 30 years in the rare metal trade is what the founder brings, the company says. Over 50 countries and regions have taken goods from the firm. The United States, Germany, South Korea and Singapore all sit on that list. Tantalum, niobium and tungsten are part of the range too. So are molybdenum, zirconium, nickel and other rare metal products. Metallurgy and electronics are two fields that use them. The medical field and special steel are two more. Custom sizes of This product can also be supplied to match your drawing. We also supply the Gr2 Titanium Pipe in custom sizes to suit your drawing.

FAQ

Q: Which material goes into Grade 2 titanium pipe?

A: This grade has no alloying elements added. The metal is commercially pure titanium. Its microstructure stays in the alpha phase. Iron is capped at 0.30%. Oxygen sits at or below 0.25%, nitrogen at or below 0.03%, and hydrogen at or below 0.015%.

Q: Which standards apply?

A: Heat exchanger and condenser tubes fall under ASTM B338. For seamless pipe, the standard is ASTM B861. Welded pipe follows ASTM B862.

Q: What strength can I expect?

A: Yield strength reaches a minimum of 275 MPa (40 ksi). Tensile strength bottoms out at 345 MPa (50 ksi). At least 20% elongation is required.

Q: How does it perform in seawater?

A: At flow speeds up to 20 m/s, the TiO2 film holds up against erosion-corrosion. Pitting and crevice corrosion are resisted too, and so is MIC.

Q: Where is it used?

A: Desalination plants are one place you'll see them. They also show up in power condensers and chlor-alkali processing. Offshore fire water systems use them as well, and so do ballast water systems.

Q: Can I order custom sizes?

A: Yes. This product sizes are made to your request. Send your dimensions and quantity to info@chdymetal.com.
