Titanium alloy pressure chamber! 150mm wall thickness, ultra-high pressure testing machine withstands 150MPa

Recently, a breakthrough in titanium alloy pressure cabin technology has triggered heated discussions across the Internet. This technology has successfully withstood a pressure of 150MPa in an ultra-high-pressure testing machine through the design of a 150mm-thick titanium alloy bulkhead, marking my country's major progress in the field of high-end materials and pressure vessels. Below is structured data and analysis surrounding this hot topic.

1. Overview of core data

2. Analysis of technical highlights

1.Material innovation:Using TC4 titanium alloy (Ti-6Al-4V), its yield strength reaches 950MPa and its density is only 60% of steel, achieving ultra-high pressure bearing capacity while reducing weight.

2.Process breakthrough:Through electron beam cladding technology, 150mm thick wall can be formed in one step, which solves the problem of grain boundary weakening caused by traditional welding. The key data comparison is as follows:

3.Application scenarios:This technology has passed a simulated deep sea pressure test of 4,500 meters (corresponding to 150MPa), providing key technical support for the country's most important equipment such as manned deep submersibles and space station modules.

3. Industry impact data

4. Expert opinions

Zhang Moumou, an academician of the Chinese Academy of Engineering, said: "This technology has elevated my country's design capabilities of thick-walled titanium alloy pressure-bearing structures to the first echelon in the world. The withstand pressure of 150MPa is equivalent to placing a 1.5-ton weight on your fingernail, and the deformation of the cabin is controlled within 0.3%. This is a milestone for strategic projects such as 10,000-meter manned deep diving."

5. Future Outlook

According to the R&D team’s disclosure, the next generation technology will focus on"Intelligent sensing pressure cabin"Develop and integrate an optical fiber sensor network to monitor stress distribution in real time, with the goal of achieving a 200MPa pressure level by 2025. The technology roadmap is as follows:

This breakthrough technology not only demonstrates the core strength of China's manufacturing, but also provides a new technological paradigm for the development of global extreme environment equipment. With the advancement of subsequent industrialization, titanium alloy thick-walled pressure-bearing structures are expected to become representatives of "new productivity" in the field of high-end equipment.
