Shaanxi Drum Technology Air Compressor enters PTA field

Shaanxi Blower (Group) Co., Ltd. has recently secured a major 600,000-ton-per-year PTA equipment supply contract with Dongfang Hope Group's Chongqing Pengwei Petrochemical Company. This milestone marks the official entry of Shaanxi Drum Process Air Compressor into the PTA industry, and it is expected to provide localized support for large-scale PTA projects in the future. Since the late 1970s, when China began developing its polyester industry, nearly 20 PTA plants have been constructed across the country. Most of these facilities relied on foreign patented technologies, which came with high costs and limited competitiveness. As a result, the adoption of domestic technology and equipment has become crucial for reducing investment and improving market competitiveness. The process air compressor is a critical component in PTA production, providing air for the paraxylene oxidation reaction and recovering energy. Shaanxi Drum has developed advanced technologies in axial compressors, energy recovery turbines, and centrifugal compressors, along with multi-unit set systems. To date, they have designed and completed nearly 2,000 such units. Over the past decade, the company has invested heavily in research and development, enhancing aerodynamic design, structural engineering, manufacturing, automation, testing, and installation techniques. These efforts have brought their products to an international standard, earning them the Second Prize for National Scientific and Technological Progress. In the field of centrifugal compressors, Shaanxi Drum has established independent intellectual property rights through integrated production and research. They have successfully designed and manufactured compressors suitable for various media, including rich gas, synthesis gas, nitrogen oxides, carbon dioxide, recycled gas, natural gas, hydrogen, cracked gas, and more. Their technology has also shown significant success in coal chemical and air separation industries. The Pengwei Petrochemical project, one of the top 10 key new construction projects under the Western Development Plan in 2007, is expected to produce 600,000 tons of PTA annually once completed in late 2008. It will use mature domestic technology, aiming to achieve the highest localization rate, lowest investment cost, fastest construction speed, and strongest competitiveness among petrochemical projects. This project is a major step forward in promoting the localization of key technical equipment in China’s industrial sector.

Fuel Hose

Fuel hoses are essential components in automotive and industrial applications, designed to safely and efficiently transport various fuels such as gasoline, diesel, and oil. These hoses are flexible, durable, and resistant to chemicals and abrasion, ensuring reliable performance in demanding environments.

Fuel hoses are typically made from synthetic rubber or thermoplastic materials, reinforced with multiple layers of braided or spiral textile or steel wire. This construction provides strength and flexibility, allowing the hose to withstand high pressure and temperature fluctuations without compromising its integrity.

The inner tube of a fuel hose is specifically designed to resist the corrosive effects of fuel and prevent leakage. It is often made from a synthetic rubber compound that offers excellent resistance to fuel and oil, ensuring long-lasting performance.

Fuel hoses also feature an outer cover that protects the inner tube and reinforcement layers from external factors such as abrasion, weathering, and UV radiation. The cover is typically made from synthetic rubber or thermoplastic materials, which provide resistance to chemicals, ozone, and other environmental factors.
