Product Description

The PU Spraying & Winding Pre-Insulated Pipe Production Line is independently developed and manufactured by Qingdao Huashida Machinery Co., Ltd. The complete line integrates three core systems: outer pipe shot blasting and rust removal, polyurethane (PU) foam spraying, and PE polyethylene winding.

Featuring multiple national patents and advanced integrated manufacturing technology, the equipment has achieved Level 5 in a third-party technical evaluation, representing a domestically leading technical standard. It has also been recognized as the First (Set) of Technical Equipment in Shandong Province.

As one of China's leading exporters of this type of equipment, Huashida provides reliable production solutions for large-diameter pre-insulated pipes. The production process achieves a PU foaming rate of over 98%, a closed-cell rate of over 95%, and water absorption below 0.5 kg/m². Its integrated forming process ensures excellent insulation performance, structural stability, and product reliability.

In municipal heating, oil and gas transportation, and petrochemical applications, the technology can reduce lifecycle costs by approximately 30% compared with traditional processes.
