Quality creates brand - innovation leads the future


Insulated steel pipe is a commonly used pipeline product, its characteristics include the following aspects:
1. Material: The base material of insulated steel pipes is usually seamless steel pipes, spiral welded steel pipes, straight seam welded steel pipes, etc. The insulation layer materials can be polyurethane, aluminum silicate, glass wool, rock wool, etc.
2. Insulation structure: The insulation structure of insulated steel pipes includes inner steel pipes, insulation layers and outer steel pipes. The bonding layer between the insulation layer and steel pipes usually uses polyurethane or epoxy resin.
3. Insulation performance: The insulation performance of insulated steel pipes depends on the material and thickness of the insulation layer. Generally, it can achieve better insulation effects, allowing the pipeline to reduce energy loss and improve transportation efficiency during the process of transporting media.
4. Technical standards: Technical standards for insulated steel pipes usually include national standards, industry standards and enterprise standards, such as GB/T 9711.2-2011 “Technical Specifications for Transportation Steel Pipes in the Oil and Natural Gas Industry Part 2: Spiral Seam Steel Pipes”, GB/T 23257 -2009 “Technical Specifications for Three-Layer Polyethylene Fatty Acid Copolymer Coating for External Anti-corrosion Steel Pipes”, etc.
5. Scope of application: Insulated steel pipes are usually suitable for pipeline systems that transport oil, natural gas, chemicals and other media to improve the transportation efficiency and energy saving and emission reduction effects of the pipeline system.
