  • Spiral pipe yield and loss rate

    Spiral pipe yield and loss rate

    Spiral pipe (SSAW) factory attaches great importance to the loss of spiral pipe. From the steel plate to the finished product rate of the spiral pipe, the loss rate of the spiral pipe manufacturer during welding directly affects the cost price of the spiral pipe. The formula for calculating the y...
