How to classify spiral steel pipe according to its working mode?
Spiral steel pipe irrigation system can be categorized into mobile, semi-fixed and fixed according to the working mode.
Mobile type. In addition to water sources, pipes and water supply equipment can be moved, some pumps are fixed, and some can also be moved. Spiral steel pipe is mostly made of film plastic hose or Velcro-coated plastic hose, which is simple and convenient, low cost, flexible and adaptable, and can cross the ditch and turn at will. However, the film plastic hose is not durable, easy to break, life is generally only 1-2 years. In the late stage of the growth of tall crops, it is difficult to move the hose between rows because the crop grows very tall.
Semi-fixed. One part of the piping system is fixed and the other part is mobile. Typically a main or trunk pipe, the branch pipe is a fixed buried pipe connected by a lead-in that moves the hose to the field. This form of branch pipe spacing is large, the outlet spacing is large, the amount of fixed buried pipe is reduced, and the investment per unit area is reduced. However, frequent movement of the hose on the ground at the site, high labor intensity, poor working conditions.
Fixed type. Low-pressure pipeline irrigation system at all levels of pipelines and water distribution facilities are buried in the ground fixed, water supply spigot or water diversion is directly divided into field furrow border, no hose connection. Field furrows are shorter, fixed spiral steel pipe density, high standards, this operation and management is convenient, uniform irrigation, but the one-time investment is relatively large.
How to manage the safety of spiral steel pipe?
For the spiral steel pipe orifice plate grouping quality exceeds the standard, the following preventive measures should be taken:
Try to use internal matching devices.
The welded pipe group does a good job in grading the welded pipe section.
Partial correction by purple copper hammer or copper washer hammer.
When the deformation of the misaligned port is flat, it should be cut.
Safety management of spiral steel pipe:
In the use of internal supporting equipment, the supporting equipment, compressor equipment and tube elevator must be well inspected before construction, and should be used flexibly according to the operating procedures.
Before the use of each other, we should carefully check whether the equipment used by each other is normal or not: in the use of special personnel must be set up, in accordance with the standard action instructions to direct the operation, in order to avoid the occurrence of accidents.
In construction, such as the use of padded mound or padded sacks of rice hulls to pad the pipeline, then the height of the padding must be strong and firm, in order to prevent the pipeline from being rolled and damaged; do not buffer the spiral steel pipe with frozen soil or stone.
