The development prospect of the double-sided submerged arc welded pipe industry is very good, because it brings more benefits to the enterprise when in use, so it is favored by customers. In order to let everyone know more, next we will talk about the advantages of double-sided submerged arc welded pipe, hoping to bring help to more people.

  double-sided submerged arc welded pipeThe development prospect of this industry is very good, because it brings more benefits to the enterprise when in use, so it is favored by customers. In order to let everyone know more, next we will talk about the advantages of double-sided submerged arc welding pipe, hoping to bring help to more people.

Nowadays, there are still many people who do not know some basic information about double-sided submerged arc welded pipes, so as manufacturers, it is also necessary for us to explain briefly. In fact, the advantages of double-sided submerged arc welded pipes are that the welding current used is large and the corresponding input power is large. Coupled with the heat preservation effect of flux and slag, the thermal efficiency is high and the penetration depth is large. The groove of the workpiece can be smaller, reducing the amount of filler metal. Single wire submerged arc welding can weld through 20mm at one time, and the workpiece has no groove. In addition to these, but also because of its high speed. Taking butt welding of 8~10mm thick steel plate as an example, the single wire speed can reach 50~80 cm/min, and the manual speed does not exceed 10~13 cm/min. Moreover, the good presence of the product can not only separate the contact between the liquid metal and the air, but also make the molten pool metal solidify more slowly. There is more time for the metallurgical reaction between the liquid metal and the molten flux, which also reduces the possibility of defects such as pores and cracks in the weld. Flux can also add some alloying elements to the weld metal to improve the mechanical properties of the metal. The protection effect of double-sided submerged arc welding pipe is better than other arc welding methods when welding in high wind environment. Stabilized by automatic adjustment. Compared with manual arc welding, the dependence of quality on the skill level of welders can be greatly reduced.

Due to the mechanization and automation of the process, the labor intensity of the double-sided submerged arc welded pipe is greatly reduced, and there is no harmful effect of arc light on welders; therefore, it emits less smoke and harmful gases during the welding process, thereby improving working conditions. The double-sided submerged arc welded pipe has good thermal insulation performance, and the heat loss is only 25% of the traditional double-sided submerged arc welded pipe. Long-term operation can save a lot of energy and significantly reduce energy costs. It has strong waterproof and corrosion resistance, so these places do not need to stick to the trench, can be directly buried in the ground or water. The construction is simple and fast, and the comprehensive cost is low. The double-sided submerged arc welded pipe also has good corrosion resistance and impact resistance under low temperature conditions, and can be directly buried in the underground frozen soil. The service life can reach 30-50 years, and the correct installation and use can make the maintenance cost of double-sided submerged arc welded pipe low. Of course, an alarm system can also be set up to automatically detect the water leakage fault of the double-sided submerged arc welded pipe, accurately indicate the fault location, and automatically alarm. Before use, it is necessary to know whether the pipeline is under pressure during use, whether the required double-sided submerged arc welded pipe meets the standard of the pipeline itself, and whether there is pressure. The working conditions of this standard include ventilation pipelines of many power plants, underground ventilation of coal mines, central heating, drinking water pipelines, etc.

The above article content is Xiaobian for everyone to introduce aboutdouble-sided submerged arc welded pipeSome information about the advantages. If you didn't know before, you can come and see it now. The next issue will also tell you about the knowledge points related to it. Remember to watch.

An analysis of the factors that lead to porosity in the weld of double-sided submerged arc welded pipes.


As we all know, the quality of double-sided submerged arc welded pipe is determined by the quality of the weld. Once the weld of double-sided submerged arc welded pipe produces pores, it will not only affect the density of the weld, cause pipeline leakage, but also become the corrosion inducing point, seriously reduce the strength and toughness of the weld. Generally speaking, the moisture, dirt, oxide scale and iron filings in the flux, welding composition and covering thickness, steel plate surface quality, steel plate side plate treatment, welding process and steel pipe forming process may be the causes of weld porosity.

Advantage sharing of double-sided submerged arc welded pipe


Double-sided submerged arc welded pipe is a welded steel pipe made of steel plate or steel strip after crimping. It has the advantages of small size deviation, uniform wall thickness, simple production process, high production efficiency, many varieties and specifications, and less equipment investment. However, because the welding performance of welded steel pipes is lower than that of seamless steel pipes, the utilization rate in petrochemical plants is very low. Double-sided submerged arc welded pipe is divided into straight seam and spiral seam according to the weld form.
