Among the many types of anti-corrosion pipes, 3PE anti-corrosion steel pipe is a common and efficient model. Its full name is three-layer structure polyethylene coating (MAPEC) external anti-corrosion steel pipe. As its name suggests, this outstanding pipeline product is like wearing a set of exquisite "three-layer armor".

Russia has a vast territory, and most of its areas are located in the northern cold zone. This extreme climatic condition places extremely stringent requirements on pipeline joint patching. In the field of pipeline laying and maintenance, the quality of pipe fittings used for patching and anti-corrosion is crucial. Once the quality of pipe fittings is not up to standard, under the erosion of Russia's harsh climatic conditions, it will not take too long for the pipeline to inevitably have serious problems such as leakage and rupture.

Qingdao Huashida Machinery Co., Ltd. has over 20 years of expertise in producing electric heat shrink sleeves, essential for connecting insulated pipes in thermal pipelines. These sleeves use PE boards with mesh covering, which are welded together using electric heat fusion to create strong, durable, and sealed joints. The special heating wire mesh ensures superior connection strength and corrosion resistance, making them an upgrade over previous generation products.

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.

Amid the 2024 economic slowdown, Qingdao Huashida Machinery Co., Ltd. has earned recognition for its advanced technology, reasonable design, excellent after-sales service, and cost-effectiveness. Despite market challenges, its sales have grown significantly.

Qingdao Huashida specializes in the production of insulated pipes equipment and 3LPE pipe coating machine, with products known for their excellent corrosion resistance, long lifespan, and impact resistance. Huashida's HDPE Electro Fusion Tape is essential for pipe jointing in construction. In Turkey, it entered the market successfully through customer recommendations, leading to significant orders.

Recently, Huang Baodong, Chairman and General Manager of Qingdao Huashida Machinery Co., Ltd., led a technical team on a business visit to Kazakhstan. During the visit, they gained a deeper understanding of the local market demand and engaged in extensive discussions with representatives from universities, enterprises, and industrial parks. This visit not only strengthened Huashida's influence in Kazakhstan but also laid a solid foundation for future strategic cooperation.

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.

In the development of modern industry, the selection of insulated pipes equipment is particularly important, especially in various fields such as municipal heating, petroleum, and construction.

Huashida's technical strength and customer service in the field of pipe insulation equipment and 3PE steel pipe anticorrosion equipment have been widely recognized. Recently, a set of vacuum sizing pipe insulation equipment, which is about to be shipped, is being prepared to be delivered to the customer located in Yulin. This customer not only purchased this equipment, but also purchased Huashida's foaming equipment, it is expected that through the application of these advanced equipment, the customer's production efficiency and product quality of pipe insulation will be significantly improved.

Qingdao Huashida Machinery Co., Ltd. has been expanding its high-end plastic machinery equipment to international markets, including insulation pipe production line and spray foaming insulation pipe production line. Recently, the company launched its wrapped steel pipe 3LPE anti-corrosion production line in Kazakhstan, marking the first time Huashida introduced a production line using spiral winding technology for anti-corrosion treatment of steel pipes in the country.

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.

The 3lpe steel pipe anti-corrosion equipment, developed by Qingdao Huashida, is an innovative solution widely used in the oil and gas industry. It primarily consists of three layers: an epoxy powder coating, a polymer adhesive, and polyethylene. This composition provides impact resistance and moisture isolation. Since oil and gas differ from ordinary substances, the equipment ensures that pipelines remain undamaged, prevent leaks, and offer extended service life.
