Choosing the right concrete pump pipe is crucial for the efficiency and safety of your construction project. This guide covers the key factors you need to consider.
Material Selection
The most common materials for concrete pump pipes include:
- ST52: Standard carbon steel, good balance of strength and cost
- 45Mn2: High manganese steel, excellent wear resistance for abrasive concrete
- Q235: Economical option for low-pressure applications
- No.20: High-quality carbon steel for precision applications
- 37Mn5: Premium alloy steel for extreme wear conditions
Size Specifications
Standard diameters range from DN100 to DN180, with DN125 being the most commonly used. Wall thickness varies from 4.0mm to 8.0mm depending on pressure requirements.
Quality Standards
Look for pipes that meet or exceed international standards such as ISO, DIN, and ASTM. Request material certificates and pressure test reports from your supplier.
