Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of buried insulated steel pipes, it is recommended to prioritize checking key technical parameters such as pipe diameter, insulation layer thickness, and temperature resistance range to ensure compatibility with specific scenarios such as municipal heating or chemical pipelines.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers can usually provide more stable product delivery in long-term cooperation.
  • In scenarios such as oil transportation or regional centralized heating, attention should be paid to the type of anti-corrosion coating and compressive strength of buried insulated steel pipes to avoid pipeline failure caused by soil corrosion or ground loads.
  • When applied in different climatic regions, it is recommended to combine the thermal conductivity and waterproof performance indicators of buried insulated steel pipes. For example, in high-altitude areas, it is necessary to strengthen the moisture-proof design of the insulation layer to reduce heat loss.

Knowledge Base

Q

Polyurethane insulated steel pipe is an efficient insulated pipeline made by combining working steel pipe, polyurethane insulation layer, and high-density polyethylene outer protective pipe (or fiberglass, etc.) through a specific process. It is widely used in heating, cooling, petrochemical, municipal engineering and other fields. The following provides a detailed introduction from five aspects: structure, performance, production process, application scenarios, and price: 1、 Structure

Q

Thermal buried polyurethane insulated steel pipe is a pipeline material used for insulation in water supply, steam, hot water and other pipeline systems. It consists of steel pipes on the inner and outer surfaces, polyurethane insulation layer, and anti-corrosion layer. The polyurethane insulation layer is a key part of the pipeline, which has good insulation performance and low thermal conductivity. This insulation layer can effectively reduce the loss of thermal energy inside the pipeline, improving

Q

The pipe surface shall be flat and smooth, free of rust, pitting, pollutants, etc., to ensure good adhesion with polyurethane foam; 2. For parts of pipelines with large slope or curvature, while ensuring stable connection, the method of bending the pipe first and then insulation can be adopted to avoid affecting the curvature of the pipeline; 3. The thickness of the insulation layer should meet the engineering design requirements, generally around 30
