Pure Titanium/Titanium Alloy Pipes for Industrial Use

Titanium pipes refer to hollow tubular products made of metallic titanium or titanium alloy through rolling, drawing, welding and other processes, which are divided into two categories: seamless titanium pipes and welded titanium pipes. With their core advantages of lightweight & high strength and extreme corrosion resistance, coupled with the characteristics of smooth inner wall and low fluid resistance, they have become core conveying materials in scenarios with strict requirements on pipeline safety and stability such as aerospace, chemical anti-corrosion, marine engineering, and medical devices. They are especially suitable for the conveying environment of harsh media such as strong acids, strong alkalis, seawater, high temperature and high pressure.

Characteristics

Lightweight & High Strength

With a density of only 4.51g/cm³, about 57% of steel, high-strength grades (such as GR5) can match high-strength steel in strength, which can significantly reduce the weight of the pipeline system and lower installation and transportation costs.

Extreme Corrosion Resistance

Extremely stable in harsh media such as seawater, strong acids (except hydrofluoric acid), strong alkalis, chlor-alkali, and wet chlorine gas. The dense oxide film formed on the surface can effectively resist corrosion, and its service life is much longer than that of ordinary stainless steel pipes and other materials.

Excellent Biocompatibility

Pure titanium is non-toxic and non-allergenic to human tissues, does not react with human body fluids, and is an ideal material for medical device pipelines.

Wide Temperature Range Adaptability

The melting point is as high as 1668℃, and it maintains stable mechanical properties in the range of -253℃ to 600℃. It is resistant to low temperatures without embrittlement and high temperatures without softening, suitable for medium transportation under extreme temperature fields.

Smooth Inner Wall and Low Fluid Resistance

The inner wall of titanium pipes has high finish and no burrs, resulting in low fluid transportation resistance and not easy to scale, which can improve transportation efficiency and reduce the risk of pipeline blockage.

Good Processing and Welding Performance

Various processing such as cutting, beveling, bending, and welding can be performed. The welded joint has high strength and good sealing performance, which can meet the installation needs of complex pipeline systems; the ductility is further improved after vacuum annealing.

Seamless Titanium Pipe Production Process

Raw Material Preparation: High-purity sponge titanium is extracted from titanium concentrate through beneficiation, chlorination, and reduction processes, and then smelted into titanium ingots with uniform composition and low impurity content through multiple times of vacuum arc furnace smelting.
Piercing and Billet Making: After heating the titanium ingot, a hollow titanium blank pipe is made by piercing with a piercing machine to prepare for subsequent rolling.
Cold Rolling/Cold Drawing: The titanium blank pipe is processed through multiple passes by a cold rolling mill or cold drawing machine, and the outer diameter and wall thickness are gradually and precisely controlled to the target size to ensure dimensional accuracy and surface finish.
Vacuum Annealing: Put the cold-rolled/cold-drawn titanium pipe into a vacuum annealing furnace, and treat it at a specific temperature and holding time to eliminate internal processing stress and improve material toughness, plasticity and corrosion resistance.
Finishing Processing: Through straightening, cutting, surface treatment (pickling, polishing, etc.), non-destructive testing (ultrasonic testing, eddy current testing, etc.) steps, the finished seamless titanium pipe with precise dimensions and qualified surface is obtained, with material inspection report and quality certificate attached.

Welded Titanium Pipe Production Process

Raw Material Preparation: Select qualified titanium plates as raw materials, and perform cutting and rolling to make tubular blanks.
Welding Forming: Adopt precision welding processes such as plasma arc welding or tungsten inert gas welding to weld the rolled tubular blanks to ensure firm welds and no defects; strictly control the protective atmosphere during welding to prevent titanium from being oxidized.
Subsequent Processing: The welded titanium pipe is optimized for dimensional accuracy and surface quality through cold rolling, straightening and other processes, and re-annealing treatment is performed if necessary.
Finishing and Packaging: Cut, clean the surface, and perform non-destructive testing (weld inspection, wall thickness inspection, etc.) on the titanium pipe, then package it, with material inspection report and quality certificate attached.
