The difference between titanium tube and stainless steel tube

Date: Feb 4th, 2024
Stainless steel pipe is a hollow long steel material, which is widely used as a pipeline for transporting fluids, such as oil, natural gas, water, coal gas, steam, etc. In addition, when bending and torsional strength are the same, it is lighter in weight, so it is also Widely used in manufacturing mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, gun barrels, artillery shells, etc.

Classification of stainless steel pipes: Steel pipes are divided into two categories: seamless steel pipes and welded steel pipes (seamed pipes). According to the cross-sectional shape, it can be divided into round pipes and special-shaped pipes. The most widely used are circular steel pipes, but there are also some special-shaped steel pipes such as square, rectangular, semicircular, hexagonal, equilateral triangle, and octagonal shapes. For steel pipes that are subject to fluid pressure, hydraulic tests must be carried out to check their pressure resistance and quality. If no leakage, wetting or expansion occurs under the specified pressure, they are qualified. Some steel pipes must also undergo hemming tests according to standards or requirements of the purchaser. , expansion test, flattening test, etc.

Industrial pure titanium: Industrial pure titanium has more impurities than chemically pure titanium, so its strength and hardness are slightly higher. Its mechanical and chemical properties are similar to those of stainless steel. Compared with titanium alloys, pure titanium has better strength and better oxidation resistance. It is better than austenitic stainless steel in terms of performance, but its heat resistance is poor. The impurity content of TA1, TA2, and TA3 increases in sequence, and the mechanical strength and hardness increase in sequence, but the plastic toughness decreases in sequence. β-type titanium: β-type titanium alloy metal can be strengthened by heat treatment. It has high alloy strength, good weldability and pressure processability, but its performance is unstable and the smelting process is complex. ​

Titanium tubes are light in weight, high in strength and have superior mechanical properties. It is widely used in heat exchange equipment, such as tube heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators and delivery pipes. At present, many nuclear power industries use titanium tubes as standard tubes for their units. ​

Titanium tube supply grades: TA0, TA1, TA2, TA9, TA10 BT1-00, BT1-0 Gr1, Gr2 Supply specifications: diameter φ4~114mm Wall thickness δ0.2~4.5mm Length within 15m
