Used HDPE 630mm Three-layer Pipe Production Machine

As a leading Chinese company, Qingdao Shende boasts robust technical expertise. Its team of engineers has tailored its core technology to meet the stringent requirements of large-diameter three-layer pipes. Three extruders work in tandem, using high-purity raw materials for the inner layer to ensure clean delivery. Reinforced components in the middle layer increase ring stiffness by 30%, ensuring it withstands heavy vehicle runover. The outer layer's anti-aging formula ensures the pipe remains durable outdoors for years. The independently developed large-scale molds achieve incredible precision, ensuring the three layers are tightly integrated. An intelligent control system ensures stable production throughout the entire process, ensuring pipe diameter tolerances within 0.5 mm, perfectly meeting engineering standards.

Don't be misled by the word "used." Qingdao Shende's equipment is of proven quality. Each recycling machine undergoes a "three-step transformation": a comprehensive inspection with precision instruments to detect even the slightest wear and tear; disassembly and complete refurbishment, with all aging components replaced with original, new ones, and the control system upgraded to an intelligent model; and a 72-hour continuous full-load trial run, where all 15 indicators meet the required standards before delivery. Pipes produced with this equipment retain their performance even after being buried for decades, easily passing project acceptance inspections.

The price advantage directly hits the pain points of businesses! New equipment costs over two million yuan, while used equipment can be purchased for just over eight hundred thousand yuan, instantly saving millions. A pipe factory in Tianjin secured a major municipal contract with this equipment, investing the savings in raw material reserves and market expansion. The investment paid back in less than six months, and monthly profits have now doubled. This is the magic of used equipment.

After-sales service guarantees worry-free production. Upon arrival, engineers provide professional technical support until everyone is proficient in operation. Routine issues are responded to within two hours, and over 300 spare parts are readily available, with next-day delivery to ensure production is not interrupted. One owner exclaimed, "This after-sales service is even more reliable than a new machine!"

Currently, municipal construction is booming, and the market for 630mm HDPE three-layer pipes holds a bright future. Qingdao Shende's used production machines, backed by intelligent manufacturing in China, offer high quality, competitive pricing, and excellent after-sales service. They consistently produce quality pipes from the moment they're turned on. Seize the opportunity, unlock wealth, and ride the wave of the large-diameter pipe market!
