Product Details

Detailed description

When measuring the elbow of the glass fiber reinforced plastic three-way measurement, place the elbow on a flat place, and first find the verticality of the nozzle with a spirit level. Hold the spirit level against the upper and lower walls of the nozzle to center the air bubbles, and the nozzle is now in a vertical position. Cover with wood chips or rubble. Use powder line to pass from the back (middle) of the elbow, fold over the two sides of the nozzle, make the inner and outer pipe walls stick to the powder line, the two lines cross, and use a square ruler to stick the powder line to the powder line. If both sides of the pink line are pasted on two right-angled sides, the angle is accurate; if one side is not pasted, the angle is not accurate. The length of the elbow is obtained by subtracting the radius of the pipe from the intersection of the two lines of powder to the outer wall of the nozzle.
