At the moment, a direct -haired electric welding pipe is the most popular product in the domestic pipe market. In the production of this type of pipes, cold -rolled barks are used, using special equipment, the barbar forms the pipe shape of the desired diameter.
The production of this type of pipes is strictly in accordance with GOST 10704-91 from the metal strips of the required width, mainly from low-alloy and structural steel. The shape of the pipes produced using this technology can be different: oval, square, round, rectangular. Round pipes are divided into straight -line and spirals
.The electric welter pipe has found wide application in modern pipeline systems and the construction of communications of industrial facilities. Electric welding pipes are used in the communal farm as elements of water/gas pipelines, at a construction site, using pipes create various designs in the form of frames, fences, profiles.
Steel power pipes are considerable competition for other types of pipes. Electric welding pipes have a number of technological advantages that ordinary pipes do not have: their seam is very strong, thanks to high -temperature electric welding. In terms of strength and tightness, electric welding pipes also surpass all the others, which is why they are used to lay gas and oil trunk.
