China Tungsten Alloy Tube for Counterweight, Find details about China Tungsten Alloy Tube, Tungsten Tube from Tungsten Alloy Tube for Counterweight
Tungsten heavy alloy tubes are suitable raw material for radiation protection, as tungsten heavy alloy tubes combination of radiographic density (more than 60% denser than lead), good mechanical strength, and low thermal expansion, good corrosion resistance, high radiation absorption (superior to lead), simplified life cycle and high strength. Tungsten heavy alloy tubes can provide the same degree of protection as lead whilst significantly reducing the overall volume and thickness of shields and containers. Tungsten alloy is non-toxic and are generally considered environmentally friendly, unlike lead or depleted uranium. Most commonly tungsten heavy alloy tubes are used as vial and syringe shielding.
Besides, tungsten heavy alloy tubes could also be used as the counterweight for oil logging, as tungsten heavy alloy tubes have special properties such as high density, high impact resistance and crack resistance, etc.
we can not only offer the tungsten heavy alloy tubes according to the international standard, but also as per customer's special requirements.
As tungsten heavy alloy tubes have high density with small capacity, high temperature resistance, reduction in press down-time, minimal extruded metal pick-up, high impact resistance and crack resistance, wonderful shock resistance, good corrosion resistance, etc, tungsten heavy alloy tubes are increasingly welcome by public.
