The spray wrap insulated pipe production line​ independently developed by Huashida consists of three parts: a shot blasting and rust removal production line, a polyurethane spraying production line, and a PE winding production line. This is an efficient and automated equipment dedicated to the production of insulation pipes for heating, cooling, petroleum, chemical and other fields. The production line has the characteristics of high precision, energy saving and environmental protection, high production efficiency, and can meet the customized needs of insulation pipes of different specifications.

Huashida itself has 21 years of pipeline R & D, manufacturing and sales experience, especially the company's core product insulation pipeline production line and 3P steel pipe anti-corrosion pipeline production line has accumulated many years of experience, has a professional R & D team and foreign trade sales team, both at home and abroad have Huashida equipment figure, many customers choose Huashida insulation pipe equipment production line, can be seen from the following points.

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.

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.

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.

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.

Qingdao Huashida, the global plastic extrusion equipment R & D manufacturer and solution provider, 70% of customers from the United Arab Emirates, the Middle East, Southeast Asia, Asia, Europe and the United States and other overseas countries. The R&D and manufacturing of insulation pipeline production line of Huashida is widely used in municipal heating, sewage, water supply, natural gas and communication pipe network construction, crude oil pipeline transportation, agricultural irrigation and other fields.

Effectively address customer concerns.

Vacuum Calibrating HDPE insulation pipe production line is the result of Huashida's in-depth study and innovative transformation of German pipe extrusion technology with its profound technical background. This series of production lines uses a highly integrated design concept to exquisitely integrate key processes such as extrusion, vacuum sizing, cooling, traction, cutting, and unloading to build an efficient, smooth and highly synergistic production system.

Huashida mainly does the manufacturing and development of insulation pipe equipment, with 21 years of production experience, in the water supply, heating, oil, natural gas, communication pipe network has a wide range of use, insulation pipe equipment products by domestic and foreign users. Huashida PERT rigid insulation pipe is also one of the products of insulation pipe equipment , what are the advantages of the equipment.

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.
