Valuable Tips for Best EPS Pre-expander Bead Conveying

2019-11-21

A good eps beads conveying pipeline system is of great significance for the safe production of enterprises, improving production efficiency and improving product quality. The high-quality eps raw material conveying pipeline system will promote the enterprises to achieve good economic and social benefits

 

THERE ARE SOME TIPS:

 

SEKECTION OF PIPE VALUES

 

According to the report, in developed countries in Europe, heavy steel pipes, aluminum

pipes, stainless steel pipes or plastic anti-static pipes are generally used as the bead

conveying pipes. The construction technology of steel pipe and aluminum pipe is

relatively high, but the inner wall is smooth, the bending angle is easy to control, the

bead conveying speed can be improved, and the pipe can be prevented from being

blocked due to the bending angle being too small. For anti-static pipes and rigid PVC

plastic pipes, the advantages are easy installation, smooth inner wall and good corrosion

resistance. However, it is easy to block the pipeline due to the electrostatic problem

of the beads, and the bending angle is 90 degrees at right angles, which has a certain

influence on the conveying speed of the beads, and obviously cannot adapt to the

large-scale production of the enterprise.

PIPE DIAMETER SELECTION AND CONVEYING DISTANCE

 

The distance and density of the beads are inversely proportional to the

conveying pipe. When long-distance production is required, the pipe

diameter is required to be small. Otherwise, the pipe diameter can be used

to increase the production capacity of the enterprise.

TECHNICAL REQUIREMENTS FOR PIPE LAYING 

 

The pipe diameter of the pipe is generally selected to be 150-350mm. The straight

connection between the feed port and the pipe should be kept within 4m without

elbow. For galvanized steel pipe, aluminum pipe, stainless steel pipe, white iron

prefabricated pipe, elbow radius requirement R≥2D The elbow is reduced as much

as possible and the conveying distance is shortened. The pipe interface should be

dispersed, and the whole conveying system should be well grounded. For anti-static

plastic pipes and rigid PVC plastic pipes, besides the requirements of the above

requirements, the outer wall of the pipe must be wrapped with 2.5mm2 bare copper

wire and well grounded (per 5m should be The horizontal distance of the wound copper

wire is less than 2D) to avoid fire caused by static sparks.
