Corrosion Resistant Tungsten Tube

The core selling point of this corrosion-resistant tungsten tube is its unparalleled long lifespan and high reliability, designed specifically for those demanding applications with zero failure.

• Applied to semiconductor CVD process: In chemical vapor deposition (CVD) equipment for chip manufacturing, as a boat or heater carrying wafers, its excellent corrosion resistance ensures long-term stability in high-temperature, corrosive process gases (such as H ₂, Cl ₂) environments, and never pollutes precious wafers.
• Applied in the photovoltaic industry: used as a support and guide tube in the thermal field system of polycrystalline silicon ingot furnaces, it can resist the erosion of high-temperature silicon vapor, with a service life far exceeding that of graphite parts, effectively reducing equipment maintenance frequency and production costs.
• Strict quality traceability system: We are well aware of your demanding quality standards. Each batch of high-purity tungsten tubes undergoes strict dimensional tolerances, ultrasonic testing, and metallographic analysis before leaving the factory to ensure that there are no cracks or pores inside. We provide a complete material certificate to ensure that every tungsten tube you purchase has a clear composition and traceable quality.

We understand that in addition to price, professional buyers also want to understand the "inner" of the product. The reason why our corrosion-resistant tungsten tube has outstanding performance lies in its core isostatic pressing process.

• Advanced isostatic pressing: Unlike traditional compression molding, we use cold isostatic pressing technology to process tungsten powder. This technology applies uniform high pressure in all directions to the powder through a liquid medium, thereby forming a tubular billet with highly uniform density and extremely low internal stress. This means that our seamless tungsten tube has a more stable foundation from its inception, and during subsequent sintering and use, it can minimize the risk of deformation, cracking, or corrosion perforation caused by uneven density.
• Precision machining and polishing: The sintered blank tube is processed by our precision CNC machine to ensure accurate tolerances for inner and outer diameters. At the same time, we provide various levels of surface polishing treatments ranging from frosted to mirror finish. The smooth inner wall can effectively reduce material adhesion, facilitate cleaning, and further enhance the corrosion resistance of tungsten pipes in high-pressure and high-purity environments.

Our advantages:

• Ultra high purity: Using high-purity tungsten powder with a purity of ≥ 99.95%, the impurity content is extremely low, eliminating preferential corrosion caused by impurities from the source.
• Dense structure: Thanks to the isostatic pressing process, the grains are small and uniform, without micro pores, which establishes a solid "barrier" for corrosive media.
• More stable performance: The uniform and dense structure brings better high-temperature strength and thermal shock fatigue resistance, significantly extending the service life.
