Product introduction

1. Material characteristics: Does Q235B adapt to DN350?

Q235B, as a commonly used carbon structural steel, has a yield strength of ≥235MPa and a tensile strength of 375-500MPa, and can stably withstand the pressure of 7-9MPa, which is completely suitable for DN350 small and medium-sized transportation conditions. The material has good plasticity and toughness, is easy to weld and process, can match the welding requirements of LSAW without complicated process, and has the advantages of easily available raw materials and low cost, which is more than 20% lower than that of Q355B material, giving consideration to practicality and economy, and is the best choice for small and medium-sized scale scenes.

2. Specification and technology: How to ensure the stability of transportation and structure?

DN350 is suitable for small and medium-sized large-scale flow transportation, which improves the transportation efficiency by 25% compared with DN300. It can meet the needs of centralized water supply, small and medium-sized heating and industrial auxiliary transportation in the district, and avoid the high cost and construction pressure of large diameter. LSAW longitudinal submerged arc welding process is adopted, and simple forming technology is used. The weld strength is close to the parent metal, and the stress distribution is uniform. After forming, the residual stress is eliminated by simple quenching and tempering treatment, and the outer diameter tolerance is controlled within 0.6%, which ensures the stability of underground and open-air laying.
