Classification and safety management of spiral pipe

First, how to categorize spiral steel pipe according to the working method?

Hot expanded steel pipe pipeline irrigation system based on the work in the method can be divided into portable, semi-fixed and fixed.  

1.Portable. In addition to the water source, pipelines and water distribution machinery and equipment can be moved. Some pumps are stationary, some can be moved. Most of the hot expanded steel pipe made of plastic film plastic hose or Vinylon coated plastic hose, the actual operation of the effective, the cost of cheap, easy to apply, adaptable. But the film plastic hose is not durable, very easy to destroy, the use of general only 1-2 years. In the high crop growth and development in the late stage, there is no way to move the plastic hose in the line with the line, because the crop grows very high.  

2. Semi-fixed immobile piping system software part is fixed, while the other part is moved. Generally, the branch pipe is fixed immobile through the pipe, the branch pipe and movable plastic hose coupling, the water will be transferred to the field. This type of approach has widely spaced branches and widely spaced outlets, which relatively reduces the total number of fixed immovable penetrations and reduces the project investment in the total area of the enterprise. Unknown, because the watering period in the field pavement plastic hose is often moved, labor efficiency is large, poor standards in the work.

3.Fixed type. Bottom pressure pipeline pipeline irrigation system in the individual pipelines and water distribution equipment are laid in the ground and fixed. Power supply plug or water distributor immediately water for the field ditches and rivers, without plastic hose coupling. Field gross pipeline short, immobile spiral steel pipe relative density, specification. This type of system software to facilitate the actual operation and management methods, watering well-proportioned, but the one-time project investment in the relative sex is very large.

Second, how to safety management of spiral steel pipe?  Quality management in order to deal with the seamless steel pipe nozzle splicing displacement and super standard problems, the following precautions should be used: (1) as far as possible to apply internal centering equipment.  (2) Do a good job of accurate measurement and maintenance work in the middle of the splicing.  (3) Do a good job of classifying the grade of welded pipe sections during assembly.  (4) Part with a copper hammer or copper money hammer effect positive.  (5) When the wrong shape of the flat and heavy to carry out laser cutting to solve.
