Huashida Machinery Co., Ltd. has earned a strong reputation in the pipe insulation industry, particularly with its innovative spray foaming insulation pipe production line. This advanced technology has helped numerous clients increase their productivity while delivering superior insulation performance for a wide range of applications.

Qingdao Huashida Machinery Co., Ltd. has earned the trust of its customers and established a strong brand reputation with its high-quality products and comprehensive services. In today’s highly competitive market, Huashida understands that relying solely on products is not enough to meet the comprehensive needs of customers; excellent service and a strong brand presence are equally important. This is one of the main reasons why Iran's REF Company chose to cooperate with Huashida.

In the world of pipeline manufacturing, the need for insulated and corrosion-resistant pipes has led to the development of specialized machinery. These machines ensure the efficient production of preinsulated pipes, which are essential for various applications, including hot and chilled water pipelines.

Since the beginning of this year, the production workshops of Qingdao Huashida Machinery Co., Ltd. have remained in a state of full-capacity operation. Orders for plastic machinery equipment, including insulation pipe production lines, 3PE steel pipe anti-corrosion production lines, and steel pipe internal & external epoxy resin spray coating anti-corrosion production lines, have seen steady growth from domestic customers, with a significant increase in orders from international clients.

Huashida Machinery Co., Ltd. has introduced its advanced 3PE anti-corrosion pipe coating production line, which uses a three-layer coating technology widely applied in the anti-corrosion treatment of pipelines for oil, gas, water, and other fluid transmission. The 3PE coating consists of a Fusion Bonded Epoxy (FBE) base layer, an adhesive middle layer, and an outer polyethylene (PE) layer, effectively preventing corrosion and extending the service life of pipelines. This production line can handle steel pipes with diameters ranging from Φ159mm to Φ4200mm, meeting various anti-corrosion requirements. The line includes several advanced systems, such as steel pipe transportation, surface treatment, dust collection, pipe heating, electrostatic spraying, coating, cooling, edge cutting, hydraulic and pneumatic control, and detection systems. These systems work together to ensure uniform and strong coating layers, with precise control over coating thickness, ensuring superior anti-corrosion, wear resistance, UV protection, and more. The 3PE coating significantly enhances the pipeline's mechanical strength, electrical insulation, waterproofing, wear resistance, and anti-aging properties, making it suitable for long-term use in harsh environments. Huashida's 3PE anti-corrosion pipe coating production line meets several industry standards, including SY/T0413-2002, GB/T23257-2009, and more, and has been exported to countries like Russia, Iran, India, and others, earning wide recognition.

The 3LPE (Three-Layer Polyethylene) coating process is essential for protecting pipelines from corrosion and wear. The 3LPE pipe equipment is used for coating the internal and external surfaces of pipes, typically in water pipeline machines and gas pipeline machines. This process involves applying a three-layer coating: FBE (Fusion Bonded Epoxy) as the first layer for corrosion resistance, followed by a polyethylene layer for mechanical protection, and a final polyethylene outer layer for added strength.
