Welcome to inquire! Contact: pay by blog. Different materials, the appearance, the type of pipe in our daily life plays an important role and significance, effectively played a prominent advantage of its own spiral plant Daegu Zhuangrui Jie, Tianjin Steel Pipe, to meet the needs of the public, thus gained considerable development, has won the attention of many users. Now, faced with the diversity of the pipe, as a consumer, how should we choose? Spiral Pipe as superior performance, excellent reputation choice spiral plant in Tianjin, it also has what can not be underestimated the impact and role in development? This series of questions, are deeply important topic of public concern. In use process, the principal stress direction of the spiral steel pipe spiral pipe plant in Tianjin GB spiral, that is indeed equivalent axial direction of pipe defects smaller than the length of straight pipe joints; secondly, because the pipeline are rolled steel spiral pipe plant in Tianjin GB spiral steel pipe impact toughness greater isotropy CVN values ??along the rolling direction than perpendicular to the rolling direction CVN value three times higher. As in pipe wall plus anti-corrosion coating, can increase the loop resistance, adding corrosion current; an external DC power supply, so that the soil pipe constitutes a negative potential, constitute cathodic protection, can eliminate the potential difference between the anode and cathode, anode and cathode from essentially abort the process aborted.
