Purchasing Guide

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

  • For procurement needs that require the use of large-diameter coated steel pipes, it is recommended to prioritize confirming key technical parameters such as pipe diameter range, coating thickness, and pressure resistance level to ensure compliance with pressure and corrosion requirements in municipal water supply and drainage or mining transportation scenarios.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers usually have more stable supply capabilities in the field of oil pipeline or fire protection system engineering.
  • In long-distance water or corrosive medium transportation scenarios, attention should be paid to the smoothness and adhesion indicators of the inner wall of large-diameter coated steel pipes to reduce fluid resistance and extend their service life.
  • During procurement, suppliers can be screened through industry platforms for statistical information, and their applicability can be evaluated based on their past practical application cases in power pipelines or chemical projects.

Knowledge Base

Q

Key points for selecting coating materials for large-diameter plastic coated composite steel pipes The selection of coating for large-diameter coated composite steel pipes should be comprehensively judged based on the conveying medium, working temperature, and construction conditions. 1. Selection based on medium temperature: If the temperature of the conveying medium is below 60 ℃, polyethylene powder coating can be considered; If the temperature is between 60 ℃ and 100 ℃, epoxy resin powder can be considered

Q

Coated steel pipes are products that use PE (modified polyethylene) for hot-dip molding or EP (epoxy resin) for internal and external coating, and have excellent corrosion resistance. At the same time, the coating itself also has good electrical insulation and will not produce electrical corrosion. Low water absorption rate, high mechanical strength, low friction coefficient, capable of achieving long-term use.

Q

Firstly, let's take a look at large-diameter coated steel pipes. It is a new type of steel pipe material that uses high-quality steel as the substrate and undergoes advanced high-temperature coating technology to form a high-quality plastic coating on the surface of the steel pipe. This coating has the characteristics of corrosion resistance, wear resistance, compression resistance, and antibacterial properties, making large-diameter coated steel pipes widely used in multiple fields. at home
