Purchasing Guide

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

  • When purchasing prefabricated buried insulation pipes, it is usually necessary to focus on key technical parameters such as pipe diameter, insulation layer thickness, and temperature resistance range, which directly affect their applicability in scenarios such as centralized heating or chemical pipelines.
  • In municipal heating projects, it is recommended to prioritize the use of prefabricated direct buried insulation pipes with high-density polyethylene outer protective layers, as their corrosion resistance and compressive performance are more suitable for long-term use in underground direct buried environments.
  • When selecting suppliers, reference can be made to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support, especially for energy infrastructure projects that require bulk procurement.
  • For high-temperature medium scenarios such as oil transportation, it is necessary to ensure that the axial shear parameters of prefabricated buried insulation pipes comply with industry standards, and to verify the consistency between the third-party testing report provided by the supplier and the actual sample.
