The performance and functions of the original color straight seam steel pipe in the specific use process fully demonstrate the operational contribution and usability. After painting and spraying white letters, the straight seam steel pipe also looks very energetic and beautiful. Now Pipe fittings, whether they are carbon steel straight seam steel pipes, carbon steel heads or carbon steel tees, crosses, and other welded pipe fittings, are all in their original color, saving on processes. Even if it is painted, it only looks good at the time and serves the purpose of preventing the surface from rusting. After the straight seam steel pipe is welded to the pipe, it still needs to be painted to prevent corrosion. Then proceed to the heat preservation process.

The performance and functions of straight seam steel pipes and original color straight seam steel pipes in the specific use process fully demonstrate their operational contribution and their use performance. After painting, white lettering was sprayed on, and the straight-seam steel pipes also looked very energetic and beautiful, adding a very good appearance. Why is this? There are two reasons. It turns out that the straight-seam steel pipe maintains its original color, and you can see the original surface without being tampered with. The construction period of straight seam steel pipes can be advanced, and they can be loaded and shipped as soon as they are produced. This is just my thought.

What is the original color straight seam steel pipe? It is to use carbon steel pipes to produce the current straight seam steel pipes, 90-degree straight seam steel pipes, 45-degree straight seam steel pipes, heads, Hebei elbow tees, and other welded pipe fittings without painting and anti-corrosion. primary color. This color includes red (this is how straight-seam steel pipes are produced during production), and cyan, which is the original color of straight-seam steel pipes. The original straight-seam steel pipes were produced and could not be sold without anti-rust paint. Most of them are semi-finished products. It has almost become an industry rule. Otherwise, it is not considered a complete straight seam steel pipe. During construction in winter, the pipes are less susceptible to impact and rupture, which increases the flexibility of construction arrangements. It is environmentally friendly and can be recycled without polluting the environment. Failure to recycle will cause secondary pollution; there are problems such as controlling the cross-linking degree and cross-linking uniformity, and the processing is complex and directly affects the performance of the pipe.

Two points teach you how to distinguish straight seam steel pipes:

Distinguish straight seam steel pipes according to the outer diameter
Those with an outer diameter between φ4.76 and φ12.70 mm are fine-diameter straight-slit steel pipes; those with an outer diameter between φ13-φ114 mm are small-diameter straight-slit steel pipes; those with an outer diameter between φ114-φ406 mm are medium-diameter steel pipes. Straight seam steel pipes; those with an outer diameter greater than φ406 mm are large-diameter straight seam steel pipes.

Distinguish welded pipes according to wall thickness
According to the ratio of wall thickness t to steel pipe outer diameter D, welded pipes can be divided into the following five categories:
①Those with t/D less than 2% are extra thin-walled pipes;
② Thin-walled tubes with t/D equal to 2-5%;
③Those with t/D greater than 5-12% are ordinary wall original pipes;
④Those with t/D greater than 12-18% are thick-walled pipes;
⑤Those with t/D greater than 18% are special original wall pipes.

Thin-walled tubes, ordinary-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. Pipes with these three wall thicknesses may be named thin-walled pipes, ordinary wall-thickness welded pipes, and thickened straight seam steel pipes in the standard.
Because of the corrosion resistance, oxidation resistance, anti-static, and other special functions of straight seam welded pipes, as well as the beautiful appearance and durability of straight seam welded pipes, it has gradually become a trend to use them to make some machinery, components, and springs. As the technological process continues to mature and stabilize, the "Xiangyang" industrial product straight seam welded pipe, which has continued to grow and develop in recent years, is gradually penetrating various fields such as practical hardware and the construction and decoration industry with its unique performance and polynomial performance. And as people become more familiar with it, its demand will become more and more rapid, and its application fields will also become wider and wider. Another example is the widely used welding rods 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 across the board, the application scope of straight seam welded pipes is also further expanding. Many industries that require new materials have adopted straight seam welded pipes. The most obvious ones are the chemical industry and chemical fiber industry. Industrial equipment transformation.
