Purchasing Guide

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

  • For procurement requirements that require the use of cast iron drain pipes, it is recommended to prioritize confirming key technical parameters such as pipe diameter, wall thickness, and pressure resistance level to ensure compatibility with the design flow rate and soil load requirements of the drainage system.
  • In scenarios such as municipal roads or underground garages that are prone to water accumulation, cast iron drainage pipes need to have high corrosion resistance and load-bearing capacity, and products with inner lining anti-corrosion coatings can be preferred to extend their service life.
  • When selecting suppliers, reference can be made to product compatibility, business qualifications, enterprise activity, industry performance, and platform statistical information, especially suitable for long-term stable supply infrastructure project procurement.
  • If the project involves high-altitude areas, additional attention should be paid to the low-temperature anti brittle cracking performance of cast iron drainage pipes to avoid damage to the pipeline structure caused by frost heave.
