Q235B Pure Water Pipes （ERW)
Q235B Pure Water Pipeline Product Introduction
Q235B is a commonly used high-quality carbon structural steel with medium strength, good ductility, and excellent weldability, making it an ideal material for water pipes. We strictly select high-quality Q235B hot-rolled steel coils from large steel mills to ensure stable chemical composition and low impurity content. The entire production process strictly adheres to national water-related product standards, guaranteeing long-term stable operation of pipelines in drinking water, domestic water, and other water conservancy projects, eliminating safety hazards and preventing water pollution.
Q235B Pure Water Pipeline Dedicated Internal Corrosion Protection Process
The inner wall of the water pipes is coated with epoxy powder coating certified for water safety. This dense, uniform, and highly adhesive coating effectively prevents microbial growth and impurity adhesion, maintaining water purity. The outer wall can be coated with various anti-corrosion coatings depending on the operating environment, including 3PE, 2PE, and epoxy coal tar, extending the pipe's service life.

Structural Skeleton | Q235B Welded Steel Pipe (Typically ERW High-frequency Welded Pipe) |
| 2. Inner Layer/ Functional Layer |
Corrosion Resistance & Water Quality Assurance | Food-Grade Plastic (Main options: • Polyethylene (PE) • Polypropylene (PP) • Epoxy Resin (EP)) |
| 3. Outer Layer/ Protective Layer |
External Protection | Hot-dip Galvanized Layer or Epoxy Powder Coating |
Steel pipes ensure "robustness": utilizing the strength and toughness of Q235B material, they guarantee the stability and reliability of the pipeline system.
Plastic pipes ensure "purity": utilizing the chemical inertness and smoothness of food-grade plastic, they ensure the water quality remains uncontaminated.
