The three-layer PE anti-corrosion structure includes fusion bonded epoxy-powder bottom layer, polymer adhesive middle layer and polyethylene top layer. The epoxy powder is a kind of thermo setting nontoxic coating, forming the high molecular weight cross linking structure coating after solidifying ,featuring good chemical anti-corrosion and higher mechanical properties.The function of epoxy-powder bottom layer is to form continuous coating ,providing excellent adhesive by agglutinating and solidifying the steel tube surface with good chemical resistance and cathodic disbanding resistance .The function of polymer adhesive is to agglutinate the epoxy powder before gelation,and to agglutinate the polyethylene top layer ,which unites all three layer together .The three layer PE process ,with the epoxy powder coating as bottom layer, binding and bundling through polyethylene,PE and adhesive ,is widely used in steel pipes anti-corrosion at home and abroad ,and applied to the oil pipeline and gas pipeline ,as well as to the gas supply and water supply for civil use.

The 3PE (three-layer polyethylene) coating system is widely used in the oil and gas industry to protect pipes from corrosion. The process involves applying multiple layers of coatings to pipes, enhancing durability and longevity. To ensure the highest quality of these coatings, advanced 3LPE pipe equipment is essential.

On January 4, Qingdao Huashida Machinery Co., Ltd. was awarded the honorary title of Top Ten outstanding Partner and won a lucky red envelope of 2000 yuan at the "Ingenuity Build Dreams and Wisdom Create the Future - Aoyuan Group 2024 year-end Summary and 2025 Sailing Conference" held by Yunnan Aoyuan Intelligent Environmental Protection Technology Co., LTD.

When it comes to selecting high-quality rubber and plastic foam insulation pipes, Qingdao Huashida Machinery Co., Ltd. stands out as the ideal choice. With a strong foundation in the production of rubber extruders, air conditioner thermal insulation pipe equipment, and rubber-plastic foam insulation pipe equipment, Huashida leads the industry in technological innovation and product excellence.

As a leading company in the insulated pipe equipment industry, Huashida recently conducted an on-site commissioning of insulated pipe equipment for a client in Saudi Arabia. During discussions, the client remarked, "Huashida's influence in the insulated pipe equipment industry is growing steadily in Saudi Arabia. Many friends and peers have praised Huashida." Indeed, as Huashida’s reputation continues to expand, this commissioning project aims to provide efficient and reliable solutions to the local energy and construction industries.

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.

If 2003 marked the founding year of Qingdao Huashida Machinery Co., Ltd., then 21 years later, 2024 is destined to be a landmark year for Huashida Manufacturing as it conquers one pinnacle after another in the global market for plastic machinery and pipe production.

Qingdao Huashida Machinery Co., Ltd. stands at the forefront of innovation with its cutting-edge production line for polyurethane spray PE wrap insulated pipes. This advanced technology integrates a polyurethane foam core with an external polyethylene protective layer, produced through a precise spray-wrapping process. Designed to meet the needs of industries such as oil and gas, municipal water supply, and district heating, these pipes deliver superior thermal performance and long-term reliability.

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.

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.

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.
