Titanium Pipes: Lightweight Strength and Superior Performance

Titanium pipes are renowned for their lightweight, high strength, and superior mechanical properties, finding widespread applications in heat exchange equipment, including shell and tube heat exchangers, coil heat exchangers, serpentine coil heat exchangers, condensers, evaporators, and transport pipelines. In terms of manufacturing, seamless titanium pipes are produced using extrusion processes, while welded titanium pipes are formed by welding rolled plates. Generally, seamless titanium pipes have relatively small wall thickness and diameter.

High-Strength Seamless Titanium Pipes: Titanium alloys exhibit remarkable strength, with a tensile strength ranging from 686 to 1176 MPa, while their density is only around 60% of that of steel, resulting in exceptional strength-to-weight ratios.

High Hardness: The hardness of seamless titanium pipes (in the annealed state) typically falls between HRC 32 and 38, showcasing elevated hardness levels.

Low Elastic Modulus: Seamless titanium pipes possess a low elastic modulus, ranging from 1.078 × 10^5 to 1.176 × 10^5 MPa, approximately half that of steel and stainless steel.

Outstanding High and Low-Temperature Performance: Even at high temperatures, titanium alloys maintain excellent mechanical properties, surpassing aluminum alloys in heat resistance. The working temperature range of advanced heat-resistant titanium alloys can reach 550–600°C. At low temperatures, the strength of titanium alloys increases, and they exhibit excellent toughness, maintaining good toughness even at -253°C.

Strong Corrosion Resistance of Seamless Titanium Pipes: In environments below 550°C, titanium rapidly forms a thin and dense titanium oxide film on its surface. This film prevents further penetration of corrosive media, providing superior corrosion resistance compared to most stainless steels in atmospheres, seawater, nitric acid, sulfuric acid, and strong alkalis.
