How to classify the spiral steel pipe?
The irrigation system of thermal expanded steel pipeline can be divided into portable, semi -fixed and fixed forms according to the method of working.
1. Mobile. In addition to boiling water sources, pipelines and water distribution machines can also move. Some pumps are fixed, and some can move. Most of the thermal expansion steel pipes are made of plastic -film plastic hose or Vinunlon plating plastic hose. The actual operation is effective, the cost is cheap, the application of spiritual stools, and strong adaptability. However, the film plastic hose is not durable for a long time, which is very easy to destroy. The use period can generally only be 1-2 years. In the middle and late stages of the growth and development of high -straw crops, there is no way to move plastic hoses in line and line, because crops grow very high.
2. Part of the software of the semi -fixed -no dynamic pipeline system is fixed, and the other part is moved. Generally speaking, the branch tube is a fixed non -dynamic pipe. The pipeline interval of this method is very large, and the exit intervals are also very large. It relatively reduces the total number of fixed non -motion pipes and reduces the project investment of the total enterprise area. As everyone knows, because the plastic hose of the pavement in the field in the pouring period is often moved, the labor efficiency is high, and the standard deviation in the work.
3. Fixed formula. The pipelines and water -assigning equipment in the irrigation system in the underwriting pipeline water pipeline are laid underground and fixed. The power supply plug or water distribution device immediately turns water into the field ditch and river channel without using a plastic hose. The capacity of the field is short, and the relative density of fixed spiral steel pipes is high and standardized. This type of system software is convenient for practical operation and management methods, and it is well -informed, but the relative investment of one -time project investment is very large.
How to manage the spiral steel pipe safety?
Quality management In order to deal with the displacement and super -standard problems during the assembly of the seamless steel pipe mouth, the following preventive measures should be adopted:
(1) Apply internal heart adjustment equipment as much as possible.
(2) Do the precise measurement and maintenance work during assembly.
(3) Do the level classification work of the welding section during assembly.
(4) Partially effective with copper hammer or copper coin hammer.
(5) Laser cutting solutions should be carried out when the wrong mouth is flattened.
