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.
The production includes the following key links: 1. Steel pipe pretreatment, rust removal and cleaning: First, the surface of the steel pipe is rust-removed, usually by shot blasting or sand blasting, to ensure that the surface is clean and free of rust, oil and other impurities. Preheating: Preheat the cleaned steel pipe so that the subsequent polyurethane can better adhere to the surface of the steel pipe during foaming. 2. Polyurethane foaming spray foaming: Mix the polyurethane raw materials through a high-pressure foaming machine and spray them evenly on the preheated steel pipe surface. The polyurethane raw materials foam rapidly on the surface of the steel pipe to form an insulation layer. 3. Wrapping the outer sheath: Wrap the outer sheath with polyethylene (PE) material on the outside of the polyurethane insulation layer to form an outer sheath. Cooling and shaping: The pipe after winding is cooled and shaped to ensure that the outer sheath and the insulation layer are tightly combined to form a stable structure. 4. Cutting and trimming Cutting: Cut the insulation pipe into the required length according to customer needs. Trimming: Trim the end of the pipe to ensure that the end surface is flat for subsequent installation and connection.
spray wrap insulated pipe production lines are widely used. Middle Eastern oil companies need high-temperature and corrosion-resistant insulation pipes for long-distance transportation of crude oil. Spraying and winding insulation pipes use high-temperature resistant polyurethane foam materials, and the outer layer uses anti-ultraviolet PE sheath to ensure that the pipe can be used for a long time in a high-temperature desert environment.
A heating company in a European country selected the Huashida insulation pipe production line to produce insulation pipes for urban central heating. The pipeline uses a high-density PE outer sheath + polyurethane spraying technology to ensure that the pipeline has excellent insulation performance in cold climates and effectively reduce heat loss.
spray wrap insulated pipes have been widely used in heating, cooling, petroleum, chemical, LNG transportation, industrial cooling water and other fields due to their excellent insulation performance, corrosion resistance and long service life. Whether in high temperature, low temperature or corrosive environment, this kind of pipe can provide stable, safe and energy-saving solutions.
