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.

With the spray wound pipe production line and one-step polyurethane insulation pipe production line manufactured by Qingdao Huashida Machinery Co., Ltd. sent to Saudi Jeddah Insulation Pipe Company, and officially landed in Riyadh, as a representative of Chinese manufacturing, Huashida became the first enterprise to spray wound pipe production line and one-step polyurethane insulation pipe production line in Saudi Arabia.

Huashida steel pipe internal and external epoxy resin anti-corrosion equipment production line, with good quality and service; At the Shandong Equipment Manufacturing Innovation Conference, Huashida took the stage to receive the certificate of second prize for the epoxy resin anti-corrosion equipment inside and outside the steel pipe.

With the shipment of the spray foaming insulation pipe machine and the One-Step Polyurethane Insulated Pipe Production Line, both manufactured by Qingdao Huashida Machinery Co., Ltd., to Jeddah Insulated Pipeline Company in Saudi Arabia and their official launch in Riyadh, Huashida has become the first Chinese company to introduce these production lines to Saudi Arabia, marking a significant achievement for Chinese manufacturing.
