Seamless Steel Pipes Lay A Solid Foundation For Construction

A so-called fluid tube appears on the field. It is actually a processed high-frequency welded pipe. The treatment method is to scrape or wear off the original weld with special equipment, and the other is to hot-roll the welded pipe.

1. Anything that is shaved or worn away will leave traces, and some are still obvious, sometimes more obvious after removing the rust with tools;2) Everyone carefully observes the following, 20# steel and Q235 have different rust due to different materials;3) The manufacturers of such pipes are afraid of taking responsibility, and their quality certificates are fluid pipes and cannot be said to be seamless steel pipes for fluids;4) Merchants selling such pipes generally require a theoretical weight settlement. Everyone knows that genuine domestic seamless steel pipes are beyond the standard thickness and are generally overweight;5) There is also a flaw detection and component inspection. These two methods have limitations because the flaw detection is difficult to distinguish between hot-rolled welded pipes.

With the progress of the society, buildings in various cities and towns have been everywhere, and at a glance, the tall buildings have towering into the sky and are full of exquisiteness. And our seamless steel pipe also plays a decisive role in the construction of the building. The first is the scaffolding. The scaffolding is white and it is what we call the shelf. The construction site is directly used in the external wall, interior decoration or the place where the floor is high and cannot be directly constructed. This is mainly safe and convenient for the construction workers to work up and down.

Compared with ssaw steel pipes, because the quality of seamless steel pipes is relatively stable and the welding is more robust, the use of the latter can reduce the occurrence of accidents in the building. In addition, we can see us in all places such as underground pipeline transportation, groundwater extraction, and boiler hot water transportation. It is precisely because of its high quality is constantly recognized by everyone. Seamless steel pipes are also a more stable and continuous improvement of the building, and continuous improvement.

Here are some common symptoms of fake steel pipes:1. Easy to appear folding. Various fold lines formed on the surface of the seamless steel tube, such defects often run throughout the longitudinal direction of the product. The reason for the folding is that the inferior manufacturer pursues high efficiency, the amount of pressing is too large, and the ear is generated, and the folding occurs at the next rolling, and the folded product is cracked after being bent.

1. There are pockmarks. The pockmark is due to the profitability of the milled steel pipe manufacturers, and the irregularities of the seamless steel pipe surface caused by the rolling and rolling wear often occur. Due to the inferior thick wall and no system, the standard is exceeded.
2. The surface is easy to lick, easy to stick steel, these impurities bite the roller Beijing galvanized angle steel to produce scars. There are two reasons for this: 1 Inferior seamless steel pipe material is uneven and has many impurities. 2 fake inferior material manufacturers guide equipment is easy to produce scars.
3. There are many pores in the material, and the adobe is cracked by the action of thermal stress during the cooling process. Cracks are easily generated on the rolled surface because the billet is an adobe and there is a crack after the adobe.
