Global Shift Toward Plastic Pipes
With 56.2% of buried drainage pipes in developed nations now made of plastic, governments worldwide are upgrading to environmentally sustainable solutions. Huashida's PE double-wall corrugated pipes-lightweight, leak-proof, and chemical-resistant-are leading this transition.
Russia's Sanctions Create Opportunities
Localized Production: Huashida's equipment enables Russian manufacturers to replace aging concrete/iron pipes efficiently.
Smart Technology: PCC control systems with touch-screen interfaces simplify operation.
Projected Growth: Export revenue to Russia is expected to surge 100% year-on-year, outpacing Middle East demand.

Huashida's Breakthrough in Russia - Seizing Post-Sanction Opportunities

Amid Western sanctions on Russia, Qingdao Huashida has emerged as a top supplier for plastic pipe equipment, capitalizing on:

Market Drivers:

 Replacement Demand: Russia's underground pipelines require renewal after 20-30 years, creating massive demand.
 Cost Advantage: Huashida's high-cost-performance equipment outperforms pricier European alternatives.

Success Stories:

Supplied municipal drainage & oil/gas anti-corrosion pipe equipment.
Praised by Russian clients: "Huashida machines operate flawlessly in extreme cold, surpassing European brands in value."
With localized support (Russian-language tech services), Huashida is redefining Russia's infrastructure supply chain.


Technical characteristics of the fourth generation of Huashida
Continuous sealed pressure around the circumference of the forming module
Water-cooled setting technology
Uninterrupted continuous water cooling, the cooling pipeline is fixed, and there is no need to unplug and plug the replacement module. The length of the cooling section: 6.3 meters
High production efficiency and low energy consumption
Product launch time: 2003

The DWCP series high-speed corrugated pipe forming machine adopts a closed water-cooled structure, and the mold base drives the left and right modules to move within the closed curve. The mold base adopts a gear dynamic structure, which has the advantages of automatic compensation for mechanical wear, smooth operation, low noise, long service life, and high synchronization. The unique design of the circulating water circuit has high reliability, good cooling effect, and low water impact in the pipeline, which improves the reliability of continuous production of pipes and ensures the surface forming quality of pipes.
