The corridor area is a large flow of people in the wet market and the ground is vulnerable to wear and tear, so it is particularly important to choose a suitable pvc floor mat. This hollow design of the hollow Non Slip Mats is very suitable for the corridor area of the wet market. The following is a brief introduction to the hollow Anti Slip Pvc Floor Mat. The first is its anti-slip design: the hollow anti-slip mat uses a special surface texture and material, which has excellent anti-slip performance. This design effectively prevents pedestrians from slipping in the corridor area and improves the safety of walking. Moreover, it is breathable: the hollow design of the floor mat allows air to circulate freely, helps to keep the ground dry, and reduces the growth of mold and bacteria, which is conducive to maintaining the cleanliness of the corridor area. Finally, its wear resistance, hollow non-slip mat made of wear-resistant materials, can withstand high intensity flow of people and friction, extend the service life, reduce ground wear.

Aerospace Science and Industry Group Testing Technology "Physical Examination" Submarine Oil Pipeline
Recently, 35 prototypes of the submarine pipeline leakage magnetic detector developed by the Third Academy of China Aerospace Science and Industry Corporation have successfully passed CNOOC Group's evaluation. The project is expected to start production this year, marking a significant step in breaking the long-standing foreign monopoly on China’s subsea pipeline inspection services.
Pipeline transportation of oil and natural gas is one of the five major industries in China, playing a vital role in the national economy. Often referred to as the "energy bloodline," it ensures the smooth flow of energy resources across the country. However, over the years, pipeline safety incidents caused by damage have become increasingly frequent, especially underwater oil and gas leaks. These accidents not only result in massive economic losses but also pose serious threats to public safety and the environment. As a result, the international community has been closely monitoring the issue.
"Submarine pipelines are difficult to inspect and even more challenging to repair," an industry expert once noted. A single detection error in pipeline corrosion can lead to maintenance costs exceeding 50 million yuan. Therefore, preventing damage to these critical energy conduits has become a pressing concern.
Magnetic flux leakage detection technology is currently regarded as the most comprehensive method for pipeline inspection worldwide. Approximately 90% of global pipeline inspections use this technique. It works by magnetizing the pipeline with a pair of north and south poles, creating a uniform magnetic field inside. When there is a defect, such as corrosion or cracks, the magnetic field leaks out at that point, which is then detected by sensors. This process is similar to how water leaks from a damaged pipe, making it an effective way to identify issues.
However, due to the complex conditions and environmental factors affecting submarine pipelines, the requirements for detector reliability and adaptability are much higher than those for land-based pipelines. Despite domestic efforts over the past two decades, breakthroughs in this area have remained elusive. As a result, foreign companies have long dominated the market, offering expensive inspection services—often costing nearly 60,000 yuan per kilometer. Additionally, foreign firms can access geographic and operational data, posing risks to national energy security.
Faced with this challenge, the Third Academy quickly developed its own magnetic flux leakage detection technology after receiving the project mandate. After 18 months of research and development, they produced the first prototypes with independent intellectual property. Zheng Li, a 29-year-old project leader, explained: “Our detectors use the pressure of oil and gas to move through the submarine pipelines. With high-precision magnetic flux leakage technology, we can detect and record both internal and external defects, enabling accurate identification and positioning of problem areas.â€
Once deployed, the magnetic leakage detectors will provide comprehensive inspection and evaluation services, much like medical check-ups. They offer detailed reports that help identify issues and recommend appropriate solutions, ensuring precise and effective maintenance of the "energy blood vessels."
Zheng Li added, “There are risks of the detector getting stuck or disassembling, especially in curved or deformed sections. However, thanks to the high reliability standards of aerospace products, our technology is competitive with foreign alternatives. Moreover, our development is tailored to China’s specific needs, offering better quality and service.â€
Currently, the team has developed detectors for 8-inch diameter pipelines and has mastered the key technologies. This is just the beginning. In the future, they plan to expand into 10-inch, 12-inch, and 14-inch series, alongside developing online testing equipment for both subsea and land pipelines. Alongside these advancements, they aim to provide pipeline data analysis, fatigue assessment, and life prediction services.
“The industrialization phase is complete,†said an official from the Third Academy. “Within two years, a 700-square-meter testing system plant and a 600-square-meter R&D center will be built. These facilities will support full-service pipeline testing, fatigue analysis, and life assessments.â€
Replacing foreign-made subsea oil spill detectors with homegrown technology is a reflection of how military defense technology is being integrated into the national economy. It also showcases the broader development of aerospace science and technology under the “big defense, big security, big integration†strategy.
With lower costs, faster evaluation times, stronger data confidentiality, and improved user experience, the “local medical examiner†is expected to take on a crucial role soon, providing reliable and secure pipeline inspection services across China.
