    702 zirconium coil

    Grade:

    Standard:

    Specification:

    Description:

    1. Common specifications: Determine the heat exchange area according to the capacity of the kettle body, usually: Ф57×3,

    Ф45×2.5, Ф38×3, Ф38×2, Ф30×3, Ф32×2.5mm, etc.

    2. Features: It has strong corrosion resistance, good thermal conductivity (thermal conductivity=0.040Cal/cm2), and long service life.

    3. The production of zirconium coils adopts the following advanced technology, so that you can completely eliminate the trouble of corrosion.

    1) All zirconium pipe connections adopt single-sided welding and double-sided forming technology to ensure the quality of the weld.

    2) Triple argon protection to ensure that the weld and heat-affected zone are not oxidized or nitrided, and weld corrosion is avoided.

    3) The zirconium tube is round-shaped at one time, no bad joints, beautiful and durable.

    4. The reaction kettle made of zirconium metal coil and glass fiber reinforced plastic kettle body is suitable for the following medium environment:

    1) The reaction temperature does not exceed 300°C.

    2) Various concentrations of hydrochloric acid, acetic acid, phosphorous acid, nitric acid, acetic acid, oxalic acid, etc. and their mixed acids (the presence of Fe3+ and F- ions will cause corrosion).

    3) Phosphoric acid whose concentration does not exceed 40% and temperature is less than 100℃.

    4) Sulfuric acid with a concentration of not more than 70%.

    5) Various concentrations of lye or molten alkali.
