Stationary Concrete Pump Pipe Important parts

The chemical resistance of the pump tube decreases as the temperature increases. Some chemicals do not affect the pump tube at room temperature, but when the temperature rises to a certain extent, it will damage the pump tube. In the chemical compatibility table must be specified in the specific environmental conditions, especially the temperature limit, can be used to determine the chemical compatibility.

Pump tubing is one of the most important parts of peristaltic pumps, and end users often miss the pipe, making it unsuitable for the desired application. Some users even use ordinary pipes instead of peristaltic pump tubes, resulting in catastrophic consequences. With the increasing number of pump tubing on the market, the difficulty in selecting pump tubing is also increasing.

The end user should refer to the chemical compatibility table for each component of the solution, not just the main ingredient, to be checked for compatibility with the tubing to be used. Some acid or solvent in contact with the pump tube for several hours or days later, even if only a trace, but also on the pump tube caused enough damage. The end user should verify each chemical substance in the solution to ensure that it is compatible with the selected pump tubing.

Many pump tubing suppliers will provide chemical compatibility tables. But engineers should be aware that chemical compatibility tables for pump tubing should be used rather than chemical compatibility tables for ordinary pipelines.

Peristaltic pumps are becoming more popular due to their non-polluting pumping characteristics and less maintenance. However, when designing or buying a peristaltic pump system, many engineers often overlook an important component - the pump tube of the peristaltic pump.

Chemical compatibility: The pipe must be chemically compatible with the fluid to be pumped in order to have good pumping performance and safety performance. With the increasing number of pipes on the market - some peristaltic pump models can be used up to 15 kinds of tubing - so users can always find a suitable pipe with a specific fluid with chemical compatibility.

Because the common piping is only in general contact with the chemical and the peristaltic pump tubing is in contact with the chemical fluid under pressure conditions, the chemical compatibility level of the common pipe can not be equated with the chemical compatibility level of the peristaltic pump tubing. Therefore, reference should be made only to the pump tubing, rather than the general chemical compatibility level of the pipe and the associated substance, which would otherwise cause the pump to fail or break the crack, resulting in damage to the pump or a hazardous accident.

The pipe shrinkage forming process is to press the tube with the same diameter as the large diameter of the pipe into the forming mold, and the metal is moved and contracted along the mold cavity by pressing in the axial direction of the tube. Size, divided into a press forming or multiple press forming. The following figure shows the simplified diameter of the concentric reducer forming diagram.

The diameter of the pipe is smaller than that of the large diameter of the reducer, and the inner diameter is expanded with the inner diameter of the tube. The expansion process mainly solves the problem that the reducer is not easy to be formed by the reduced diameter, Sometimes according to the material and product forming needs, the diameter and diameter reduction method combined use.
