Qingdao Huashida Machinery Co., Ltd. has built a long term R&D partnership with the Plastic Machinery Research Institute of Beijing University of Chemical Technology, Qingdao University of Science and Technology, and Qingdao University of Technology. The collaboration focuses on four key areas: process optimization, intelligent control, material compatibility, and high efficiency production of large diameter pipes. These efforts have broken through industry bottlenecks and laid a solid foundation for delivering truly one stop solutions.
Huashida has achieved full spectrum design, R&D, and manufacturing capabilities for 3PE steel pipe anti corrosion coating lines, covering:
Standard diameters
Φ50–325, Φ159–820, Φ219–1420
Medium to large diameters
Φ500–1820, Φ600–2500
Ultra large diameters
Φ1000–3200, Φ1000–4200
Specialized lines
One step O wrap 3PE
External 3PE + internal epoxy
External 3PE + internal painting
Elbow pipe coating lines (Φ50–325, Φ400–1200)
High end export lines
High speed spray wrap coating
5PP anti corrosion coating
Submarine concrete weight coating for immersed pipes (Φ300–1500, Φ500–1620, Φ630–3200)
Huashida has achieved milestone progress in 3PE coating technology:
Efficiency – 800 m²/h, an internationally leading production speed, 2–3 times the domestic average.
Intelligence – Control systems on par with global advanced manufacturers.
Standards – Full compliance with international rules and specifications, positioning Huashida as a global icon of Chinese anti corrosion equipment.
Based in China and serving the world, Huashida follows a dual strategy: high end domestic substitution + global export. We align ourselves with China’s carbon reduction goals, new infrastructure initiatives, and the Belt and Road vision. Our mission is to provide Chinese technology, Chinese equipment, and Chinese solutions for the world’s energy arteries.
Domestically, we lead industry upgrades and support self reliance in national pipeline networks, petrochemicals, and offshore engineering. Globally, we compete in high end markets with our advantages in speed, intelligence, and large diameter capabilities, building Huashida into a benchmark Chinese brand for anti corrosion equipment worldwide.
In China
Our equipment is widely used by state owned giants such as Sinopec, CNOOC, PowerChina, and China Nuclear Power, as well as by more than 100 private pipeline companies including Hunan Tianzhu and Hefei Huarui.
Internationally
We serve clients across Europe, Central Asia, the Middle East, and Africa, including Rosneft (Russia), Saudi Aramco, KazMunayGas (Kazakhstan), and Palma (UAE). Our strong presence along the Belt and Road has made Huashida a trusted partner for energy infrastructure projects around the globe.
