Insulated pipes are essential in many industries, especially for applications requiring temperature control, such as district heating, chilled water systems, and energy-efficient buildings. The use of advanced insulation pipe equipment ensures that pipes maintain optimal temperatures while minimizing energy loss. Key machines in the production of insulated pipes include the HDPE Jacket Pipe Machine, HDPE Shell Machine, Pre-insulated Pipe Machine, Chilled Water Pipe Machine, and District Heating Pipe Machine.

The 3PE (Three-Layer Polyethylene) coating process is a crucial method for enhancing the durability and corrosion resistance of pipes used in various industries, such as oil and gas, district heating, and water transportation. This process involves applying three protective layers to the exterior of steel pipes: Fusion Bonded Epoxy (FBE), an adhesive layer, and a final outer layer of polyethylene.

In the field of pipeline engineering, the repair is the key link to ensure the safe operation of the pipeline, and the heat shrinkable sleeve is an indispensable material in the repair operation.

In the Arab region, the harsh environment threatens pipelines. With its excellent performance, Huashida 3PE coating tightly wraps the pipelines, effectively resisting corrosion and other damages, comprehensively safeguarding pipeline safety.

In many fields such as oil and gas pipelines and water pipelines, 3PE (three-layer polyethylene) coating is playing a vital role as an excellent anti-corrosion technology. It not only has excellent corrosion resistance and high mechanical strength, but also has remarkable UV resistance. It can provide reliable protection for pipelines in various harsh environments, and its application in cold regions is even more significant.

From Estrangement To Open-Mindedness - Huashida Brand Enters Saudi Arabia Documentary Abdo, who is at the helm of the Saudi Jeddah pipeline company, is an old man in his 70s, although he believes in Muslims, but he is an open-minded person, and the work is still busy and brisk. Since Jeddah Company introduced a thermal insulation pipe production line from Qingdao Huashida Machinery Co., LTD., many years ago, the two sides often come to each other and have close contacts.

Insulation pipe equipment is crucial for producing pipes with thermal insulation, commonly used in industries like construction, oil and gas, and energy. These pipes are designed to maintain temperature control and protect the pipe from environmental elements. The insulation process involves a range of specialized machinery, each serving a unique function to ensure high-quality insulation performance.

As the Spring Festival of the Year of the Snake approaches, most factories are immersed in the relaxed atmosphere of the holiday, but Huashida has started a busy production and delivery mode. In Huashida's factory, there is a busy scene, and workers are busy loading and shipping a set of 1200-type insulation pipe production lines. This production line includes a series of products such as steel pipe rust removal machines, pipe threading machines, pipe threading platforms, foaming machines, foaming platforms, heating furnaces, etc. It is large in scale and requires 8 large trucks to complete the transportation. It will be shipped to Yekaterinburg, Russia for the first time.As the Spring Festival of the Year of the Snake approaches, most factories are immersed in the relaxed atmosphere of the holiday, but Huashida has started a busy production and delivery mode.

In modern industry and infrastructure construction, pipelines are important carriers for transporting various media, and their safety and durability are of vital importance. 3PE anti-corrosion technology, as an advanced pipeline external anti-corrosion process, has been widely used in many fields due to its excellent performance, providing a solid guarantee for the long-term stable operation of pipelines.

Huashida HDPE Jacket pipe extrusion line for pre-insulated pipe, with its excellent performance, occupies an important position in various pipeline insulation engineering fields. Its thermal conductivity is extremely low, just like a solid heat barrier, which can effectively block heat transfer and greatly improve energy utilization efficiency. The insulation pipe is carefully built with advanced technology and high-quality raw materials to ensure that the insulation effect is long-lasting and stable, without excessive interference from time and environmental factors.

Foamed rubber pipe is a tubular material composed of rubber and plastic, usually made of a mixture of rubber and plastic or composite materials, combining the characteristics of rubber and plastic advantages, the advantages are very obvious.

Epoxy Fusion Bonded Epoxy (FBE) coating has become the preferred technology in the field of steel pipe corrosion protection due to its outstanding corrosion resistance. It is widely applied in critical industries such as oil and gas, chemical, power, and water supply. The epoxy FBE coating​ forms a durable and uniform protective layer through a strong bond with the steel pipe surface, providing long-term and reliable corrosion protection, ensuring stable and safe operation of pipelines even in extreme environments. The core advantage of epoxy FBE coating lies in its exceptional corrosion resistance. The coating undergoes a chemical reaction with the steel pipe surface to form stable covalent bonds, significantly enhancing the adhesion to the metal substrate. This greatly improves the pipe's resistance to water, acids, alkalis, salts, and various chemicals, effectively preventing corrosion and significantly extending the service life of the pipe. Additionally, epoxy FBE coatings have excellent high-temperature resistance, maintaining their integrity even in high-temperature operating environments. The coating does not peel or degrade due to temperature fluctuations, making it an ideal choice for pipelines in industries such as oil and gas where high temperatures are common.

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.
