First of all, preparations need to be made before the construction of refrigeration seamless pipe insulation. Preparation work includes material preparation, tool preparation and construction environment preparation. In terms of material preparation, it is necessary to purchase insulation materials that meet the requirements, such as polyurethane insulation steel pipes, insulation elbow tees and other pipe fittings, valves, etc. In terms of tool preparation, you need to prepare a power supply, welding machine, insulation layer thickness measurement tools, etc. Construction environment preparation includes cleaning the construction area to ensure that the construction site is clean and tidy to avoid adverse effects on the insulation construction.
Next are the steps of refrigeration seamless pipe insulation construction. First, the seamless pipe needs to be hoisted. According to the actual needs of the construction site, the seamless pipes are hoisted according to the installation requirements to ensure that the welders can easily assemble during welding.
Then there is the welding of the insulated steel pipe. Before welding, you need to know whether the pipeline requires ultrasonic flaw detection. If not, the welding process is relatively simple. If ultrasonic flaw detection is required, the pipeline must first be subjected to sub-arc welding.
Note: Ultrasonic flaw detection refers to a technology that uses ultrasonic waves to non-destructively inspect internal defects and scars in materials or mechanical components. It is widely used in machinery, metallurgy and other departments. The principle is that when ultrasonic waves propagate in the material being tested, changes in the material's acoustic properties and internal organization will have a certain impact on the propagation of ultrasonic waves. The technology of understanding the material properties and structural changes by detecting the degree and condition of the impact of ultrasonic waves is called Ultrasonic testing. Ultrasonic testing methods usually include penetration method, pulse reflection method, tandem method, etc.
It should be noted that during the construction process of refrigeration seamless pipe insulation, attention should be paid to safety issues. Construction workers should wear work clothes and safety helmets, use appropriate protective measures, and follow relevant operating specifications. At the same time, it is necessary to regularly check the status of the insulation layer and insulation layer, and perform timely maintenance and repair to ensure the long-term stable operation of the refrigeration system.
Through the detailed introduction in this article, we understand the specific steps and precautions for the construction method of refrigeration seamless pipe insulation. Maintaining good construction quality and maintenance will help improve the energy efficiency and service life of your refrigeration equipment. The refrigeration seamless pipe insulation construction method does play an important role in the refrigeration system and is of great significance to ensure the normal operation of the system and energy conservation.
