Ⅰ. product features:

    Youjiete composite water stop plate flange (Strengthened inward-flanged manhole well (1400)) is made of high strength SMC single-die molding, which has the following advantages:

1. Good size consistency, no deformation and good interchangeability;

2. SMC molding once molding high strength, beautiful appearance;

3. Good product stability, high degree of automation and easy mass production;

4. Good matching with oil tank and easy construction of multiple baselines;

5. Installation operation can be carried out for oil tanks of different diameters.

Ⅱ. Product size:

Overall size: Φ1500X443mm

Net weight: 42kg

Ⅲ. Product installation instructions:

1. Lift the flange of composite water stop plate (hereinafter referred to as flange) to the manhole position of the oil tank, align the marking, remove the flange, and polish 150mm inside and outside the marking area with the grinding wheel of Angle grinder louver, then polish the metal oil tank to produce new metal, and then polish the surface of the glass fiber reinforced plastic oil tank.The following schematic diagram and on-site operation photos:

2. Polish the inner and outer areas of the flange with a height of 100mm into pitted surfaces, and polish all the pitted surfaces in the bonding areas as shown below:

Figure 4 shows the gray and white areas

3. Lift the flange onto the oil tank and install the flange with butt datum line and direction arrow aligned with the oil tank axis, as shown below:
