Black Square Tube Application and Preservation

Black square tube is a name of square tube and rectangular tube, strip is made after processing. Generally, the strip steel is disassembled, flat, coiled, welded to form a round pipe, and then rolled by a round pipe into a square pipe and then cut into the required length.

In the field of engineering, there are many uses of square moment pipe, such as galvanized welded square pipe for low pressure fluid transmission, welding square pipe for mining liquid conveying, large diameter electric welding square pipe for low pressure fluid transmission, stainless steel welded square pipe for mechanical structure, etc.

Large diameter black square tube is also known as rectangular square tube, according to the cross section integral for square tube, square tube, mouth opening square tube, wavy pattern square tube, etc., according to the production process is divided into hot rolling seamless splicing large diameter square moment tube, cold pull seamless splicing large diameter square moment tube, extrusion forming seamless splicing large diameter square moment tube, electric welding welding large diameter square moment pipe.

Black square tube is widely used, construction, machinery, shipbuilding, electric power, agriculture and animal husbandry, storage, fire protection, home appliances and other industries will be used, can be said to be an indispensable part of the development of modern industrial steel. The black square tube is an indispensable part of the field of construction. With the hot construction project, the demand for the other steel pipe is also increasing, so how to save the square moment tube?

Generally, the pipe will be stored in the place or warehouse, and to drainage unobstructed, it is best to keep the pipe away from harmful gas. If it is a relatively small square pipe, you can deposit it in a well-ventilated material shed, and then pad some cushions under the square pipe, to avoid the direct contact of the square pipe with the ground.

Black square tube is a kind of steel tube with equal and unequal length of edges. It can be divided into square tube and moment tube. This is because the cross street area is different, square is square tube, rectangular is moment tube. In terms of use, the two kinds of steel pipes are also different. The square pipe is used for construction, machinery manufacturing, steel construction and other projects, and the moment pipe is used for fluid transportation pipelines, such as oil, natural gas, water, gas, steam and so on.

Seamless square tubes in air will corrode oxides formed by heating may have a significant impact on point corrosion performance. Hot dip galvanized square tube by microtissue plays an important role in the corrosion resistance of alloy. Various phases, such as sulfide inclusion, 3 fertin. Phase, sensitized grain boundary and weld may have a decisive impact on the point corrosion resistance of steel, they are the more sensitive parts of the point corrosion.
