The performance and function of the primary color straight seam steel pipe in the specific use process, the fully demonstrated operational contribution, and the resulting use performance, after painting, spraying white words, the straight seam steel pipe also looks very spiritual and beautiful. Pipe fittings, whether it is carbon steel straight seam steel pipe, carbon steel head or carbon steel tee, four-way, or other welded pipe fittings, are all primary colors, saving the process. It was painted, but it was only good-looking at the time, and it played the role of not rusting on the surface. After the straight seam steel pipe is welded to the pipe, it still needs to be painted and anti-corrosion. Then the heat preservation process is carried out.
The performance and function of the straight seam steel pipe and the primary color straight seam steel pipe in the specific use process, the fully demonstrated operational contribution, and the resulting use performance. After painting, spray white words on it, and the straight seam steel pipe also looks very energetic, very beautiful, and adds a very good appearance. This is why, for two reasons. It turned out that the straight seam steel pipe maintains the original color, the original surface can be seen, and it will not be manipulated by deception. The construction period of the straight seam steel pipe can be advanced, and the production can be loaded and left.
What is the primary color of straight seam steel pipe, that is, carbon steel pipe is used to produce the existing straight seam steel pipe, 90-degree straight seam steel pipe, 45-degree straight seam steel pipe, head, Hebei elbow tee, and other welded pipe fittings are not painted and anti-corrosion? primary color. This color is red (the straight-seam steel pipe is pushed out in the production process), and there is also a cyan color, which is the straight-seam steel pipe of the primary color. The original straight-seam steel pipe was produced without anti-rust paint and could not be sold. Mostly semi-finished products. It has almost become an industry norm. Otherwise, it is not a complete straight seam steel pipe. During construction in winter, the pipes are not easy to be impacted and rupture, which increases the flexibility of construction arrangements and is environmentally friendly and can be recycled without polluting the environment. If it cannot be recycled, it will cause secondary pollution; there are problems such as controlling the degree of cross-linking and cross-linking uniformity, and the processing is complicated and directly affects the performance of the pipe.
Two points teach you how to distinguish straight-seam steel pipes:
Distinguish straight-seam steel pipes by an outer diameter
Small-diameter straight-seam steel pipes with an outer diameter between φ4.76-φ12.70 mm; small-diameter straight-seam steel pipes with an outer diameter between φ13-φl14 mm; medium-diameter steel pipes with an outer diameter between φ114-φ406 mm Straight seam steel pipe; large-diameter straight seam steel pipes with an outer diameter greater than φ406 mm.
Distinguish welded pipes according to wall thickness
Welded pipes can be classified into the following five categories according to the ratio of the wall thickness t to the outer diameter D of the steel pipe: (1) those with t/D less than 2% are ultra-thin-walled pipes; (2) those with t/D equal to 2-5% are thin-walled pipes; (3) t/D Those with more than 5-12% are ordinary wall pipes; ④ those with t/D greater than 12-18% are thick-wall pipes; ⑤ those with t/D greater than 18% are special-wall pipes.
Thin-walled tubes, normal-walled tubes, and thick-walled tubes are not conceptually distinguished by the value of wall thickness. However, some standards have three different wall thicknesses corresponding to the same outer diameter. The pipes with these three wall thicknesses may be named thin-walled pipes, ordinary wall-thickness welded pipes and thickened straight-seam steel pipes in this standard.
Because of the special functions such as corrosion resistance, oxidation resistance, anti-static, and so on, as well as the beauty and durability of the straight seam welded pipe, it has gradually become a trend to use it to make some machinery, components, and springs. With the continuous maturity and stability of the technological process, the "Xiangyang" industrial product straight seam welded pipe, which has been developing and growing in recent years, is gradually infiltrating and infiltrating into practical hardware, construction, and decoration industry and other fields with its function and polynomial function. . And as people become more familiar with it, its demand will become more and more rapid, and its application field will become broader and broader. Another example is the widely used welding rod and a large number of stainless steel components, connectors, etc., whose fields have also been widely occupied by straight-seam welded pipes. In addition, with the development and rational use of high-tech products, the application range of straight-seam welded pipes is also further expanded. Industrial equipment transformation.
