One quarter of domestic radial tires failed

October 02 11:07:57, 2025

Recently, the AQSIQ (General Administration of Quality Supervision, Inspection and Quarantine) released inspection results on the quality of car radial tires nationwide. The findings revealed that only 53% of the products passed spot inspections, while the sample sampling pass rate stood at 75%. These figures highlight a pressing need for improvement in the quality of domestically produced radial tires. As a high-tech product, car radial tires offer better performance compared to bias-ply tires and are considered the future direction of the tire industry. The inspection focused on 6.50R16 light truck radial tires as well as 70 and 80 series passenger car radial tires. Out of 28 samples tested across 15 companies, 21 samples from 8 companies met the required standards. However, seven samples failed. Notably, six of these failures were related to the outer edge size, which is a critical dimension affecting vehicle performance. When this measurement is not within acceptable limits, it can lead to improper driving conditions and pose serious safety risks, especially at high speeds. Industry experts point out three primary reasons behind the non-compliance. First, some manufacturers fail to strictly control the quality of imported raw materials. Second, there is often inadequate oversight during the production process. Third, some companies produce tires that do not meet national mandatory standards or instead follow foreign specifications, leading to products unsuitable for the domestic market. This discrepancy between international and local requirements further complicates quality assurance efforts. Improving quality control at every stage of production and ensuring compliance with national regulations will be essential for the long-term growth and competitiveness of the domestic tire industry.

Mechanical Seals For Pumps

Mechanical Seals are essential components in pumps, playing a crucial role in preventing leakage and ensuring the efficient operation of the pumping system.
Mechanical Seals For Pumps are designed to create a tight seal between the rotating shaft and the stationary housing of the pump. They consist of several parts, including a stationary seal face, a rotating seal face, springs, and other components. These seals work by creating a barrier that prevents the pumped fluid from escaping along the shaft.
Mechanical Seal For Water Pump is a specific type of mechanical seal designed for use in water pumps. Water pumps often handle a wide range of fluids, including clean water, wastewater, and chemicals. The mechanical seal for water pump is designed to withstand the specific conditions and requirements of these applications.
Mechanical Seals For Pump come in various designs and configurations to suit different types of pumps and operating conditions. Some common types include single spring seals, double spring seals, and cartridge seals. Each type has its own advantages and disadvantages, depending on factors such as pressure, temperature, and fluid compatibility.
Pump Seals are another term used to refer to mechanical seals for pumps. These seals are available in different materials, such as carbon, ceramic, and silicon carbide, to meet the specific needs of different applications. The choice of material depends on factors such as the type of fluid being pumped, the operating temperature, and the required durability.
In conclusion, mechanical seals for pumps are critical components that ensure the reliable and efficient operation of pumping systems. Whether it's a mechanical seal for a water pump or a general mechanical seal for a pump, these seals play a vital role in preventing leakage and maintaining the integrity of the pumping process. Pump seals come in various designs and materials to meet the diverse requirements of different applications.
