Spiral steel pipe manufacturers to discuss its factory process
From the surface of the spiral steel pipe to see the processing technology of the spiral steel pipe is not exquisite, generally speaking, good pipe manufacturers in the processing level will be careful, there will not be some friction problems, and on the other hand to knock the -+metal spiral steel pipe, if the sound is brittle and the echo is not very turbid, that the pipe is OK, Instead of waste pipe recycling application
The development of pipe processing upgrade structure, such as multi-layer pipe, that is, the thickness of the strip steel welding process is half of the wall thickness of the multi-layer pipe, not only the compressive strength is higher than that of the thickness of the single-layer pipe, and will not show cold and brittle damage; Engineering construction is fast, simple links save time and labor, production plant and construction site can be engineering construction.
The process is relatively simple and does not require serious facilities and sites. Usually, spiral steel pipe manufacturers can continuously check the way online to ensure that the welding process of the weld is good or bad. This is another key characteristic of spiral steel pipe processing different from spiral steel pipe processing.
Spiral welded pipe production technology
Shipments from spiral welded pipe manufacturers have brought the necessary standards to ensure the processing time of large quantities of spiral pipe, which is still widely used today
The compressive strength of spiral welded pipe is usually higher than that of straight welded pipe. Narrow billet can be used to process welded pipe with larger diameter, and different welded pipe can be processed with the same clear width billet.
The spiral welded pipe for circulating water has single-layer welding and double-sided welding. The welded pipe should ensure that the hydraulic test, compressive strength and cold bending characteristics of the weld should meet the requirements.
Continuous inspection is beneficial to the supervision of welding process defects, the stability of welding process and the assurance of welding process grade. Because of the processing process of the tube bundle, spiral steel pipe is extremely difficult to complete continuous inspection. This will reduce the probability of welding process hazards and quality problems, and even endanger the overall operational reliability of pipeline operation in the future.
From the appearance of the anticorrosive spiral pipe to see whether its production technology will be fine, usually good spiral steel pipe enterprises in production will be careful and meticulous, there will be no grinding defects, at the same time to knock metal pipe, if the sound is crisp and echo is not very dirty, that spiral steel pipe is the latest choice, Instead of waste anticorrosive spiral pipe recycling
