Pure Tantalum Seamless Pipe

Chemical industry: sulfuric acid concentration evaporator pipeline, hydrochloric acid transportation main pipe, nitric acid reactor connecting pipe, organic acid (such as acetic acid) transmission system.

Hydrometallurgy: metal leaching acid delivery pipe, electrolytic tank circulation pipeline​

Semiconductor industry: high-purity acid (such as etching liquid except hydrofluoric acid) delivery pipeline for wafer cleaning​

Pharmaceutical industry: Corrosive reagent transmission tubes and sterile strong acid delivery systems in API synthesis

Environmental protection industry: industrial waste acid recovery device pipelines, high-concentration acid mist treatment pipelines

Extreme corrosion resistance, covering many types of strong acid scenes​

Tantalum exhibits excellent stability against almost all strong inorganic acids, and the key performance data are as follows:​

Hydrochloric acid: no corrosion in the full concentration range and boiling temperature, and can withstand the continuous delivery of 37% concentrated hydrochloric acid for a long time​

Sulfuric acid: The corrosion rate is as low as 0.0004mm/year below 175℃, and can still be controlled within 0.006mm/year at 200℃​

Nitric acid and aqua regia: no chemical reaction at room temperature to boiling temperature, suitable for transporting strong oxidizing acids​

Phosphoric acid: Stable operation below 150°C, corrosion rate controllable in high temperature scenarios, performance better than zirconium and nickel-based alloys​

In extreme working conditions such as boiling concentrated hydrochloric acid, the corrosion resistance stability of tantalum pipes significantly surpasses Hastelloy C276, titanium alloy and other materials, completely solving the pain points of frequent leakage and replacement of traditional pipes.​

Seamless structural design to eliminate the risk of leakage​

Using powder metallurgy blanking, extrusion molding + precision drawing process, there is no welding link in the whole process, eliminating weld corrosion, cracking and other hidden dangers from the root. The structural advantages are specifically reflected in:​

The wall thickness tolerance is precise (±5%) to ensure uniform stress on the pipe body​

Internal surface roughness Ra≤0.8μm to avoid local corrosion caused by acid residue​

Anti-explosion pressure exceeds 45MPa (standard specification), suitable for high-pressure and strong acid delivery systems​

High-purity material to ensure the purity of the medium​

Strictly control the impurity content (Fe≤0.03%, Si≤0.02%, O≤0.02%) to avoid catalytic reactions with strong acids; at the same time, it has:

High melting point (3017℃), can operate stably in the range of - 200℃~260℃, suitable for high and low temperature strong acid working conditions.

Excellent thermal stability, no material embrittlement after long-term use, performance better than 316L stainless steel, Monel alloy​.

Long service life, significant cost reduction and efficiency increase​

Although the initial purchase cost is higher than that of traditional materials, in strong acid scenarios, the service life can be 5-10 times that of Hastelloy and more than 20 times that of 316L stainless steel.
