It should be noted that the position of the disc from the calibration line can be adjusted according to the reinforcement diameter, and R and R can be equal or different.It is the process of drawing the die hole of the rolled metal blank (shape, pipe, product, etc.) into a section to reduce the length and increase. It is mostly used for cold processing.Pareso,Functional index analysis of square tube - mechanical function of plastic square tube. special shaped square pipe is the general name of square pipes with other cross-section shapes except circular pipe. According to the different cross-section shape and size of steel pipe, it can be divided into special-shaped square pipe with equal wall thickness (code D), special-shaped square pipe with unequal wall thickness (code BD) and special-shaped seamless steel pipe with variable diameter (code D) These special-shaped large-diameter qb square tubes are widely used in various structural parts, tools and mechanical parts. Compared with circular tubes, special-shaped tubes generally have large moment of inertia and section modulus and have large bending and torsion resistance, which can greatly reduce the structural weight and save steel. Square tubes are an indispensable part of construction workRekhasim,According to smelting classification and furnace type, A. open hearth steel: (a) acid open hearth steel; (b) Alkaline open hearth steel.With the improvement of production quality,ParesoWhere are galvanized pipes,ParesoHow much is a meter of galvanized round pipe, the quality of square tubes is getting better and better. The quality of square tubes will affect our lives. Because the functions of square tubes are different, their characteristics and uses are different. I will introduce the characteristics and uses of square tubes in detail.The surface of fake and inferior square tubes is easy to produce scabs. There are two reasons: the material of fake and inferior square tubes is uneven and there are many impurities. The guide equipment of fake and shoddy material manufacturers is simple and easy to stick to steel. These impurities are easy to scar after biting the roll.

The difference between hot-dip galvanized square pipe and cold-dip galvanized square pipe is mainly from the following aspects: the appearance of hot-dip galvanized square pipe is slightly rough compared with cold-dip galvanized square pipe; The appearance of cold galvanized square pipe is smooth and bright.Function index analysis of square tube - the strength acts on the parts in a great progress. The load on the parts is called the charge and trap load. The power of square tube destruction under the charge and trap load is called the charge and trap toughness.The pressurization size and time are the key to the success or failure of welding. If the square tube synthetic material is not pressurized, a large number of pores will be caused due to the pores of the material itself and the gas generated in the reaction. It is not allowed to leave the reactants in the weld, so it must be densified, usually pressurized during the reaction.Bidding,Stainless steel square tube for fluid transportation (gbt-) is a hot-rolled (extruded, expanded) and cold drawn (rolled) square tube made of stainless steel for fluid transportation.Square tubes for petroleum cracking (gb-) are furnace tubes heat exchangers and pipeline square tubes suitable for petroleum refineries.Viewing color: the color of the cold galvanized square tube is yellowish green, cyan white or slightly colored at a fixed angle with the sun. The color of hot-dip galvanized square pipe is silver white at a fixed angle with the sun.

, cold drawn tubes, tubes, etc. Hot rolled seamless tubes are produced on the automatic precision tube precision tube rolling mill. The solid tube blank is cut into the required length by removing surface defects, centering on the end face of the perforated end of the tube blank, and then sent to the heating furnace for heating. It is perforated on the piercing machine. At the same time, it rotates and advances continuously under the action of roll and plug, A cavity is gradually formed inside the pipe blank, which is called the rough pipe, and then sent to the automatic pipe mill for continuous rolling. After the wall thickness is adjusted by the whole machine, and the diameter is determined by the sizing machine to meet the specification requirements. The continuous pipe mill is more advanced in producing hot-rolled seamless steel pipe. If you want to obtain seamless pipe with smaller size and better quality, Cold rolling and cold drawing must be adopted, or the combination of cold rolling and cold drawing is usually carried out on the roll mill. The seamless pipe is rolled in the annular pass composed of variable section circular hole groove and fixed conical plug. Cold drawing is usually carried out on the single chain or double chain cold drawing machine that is, the heated pipe blank is placed in a closed cylinder, and the perforated rod and rod move,ParesoLined plastic hot dip galvanized steel pipe, This method can produce steel pipe with small diameter. In the building materials industry, the development of various pipes is different. Because of their different characteristics, there is a certain distance between pipes. Square pipe is one of many pipes in the building materials industry. It is formed after strip steel treatment. We need to understand the various characteristics of steel pipes. However, in the building materials industry, the development of various pipes is different. Because of their different characteristics, there is a certain distance between pipes. Square pipe is one of many pipes in the building materials industry. It is formed after strip steel treatment. The various characteristics of steel pipe need to be understood by everyone. However, due to the of steel pipe and other raw materials, the storage of steel pipe needs specific conditions.Create brilliance,Square pipe for conveying flammable and non flammable fluids, Standard No.: gbt (gbt - ). The representative material is l-l pipeline steel. It is mainly used to transport flammable and non flammable fluids. Low pressure or high pressure square pipes have high requirements. The purpose of large-diameter qb square pipe is qb square pipe, C-shaped steel and H-shaped steel. It is mainly used in the construction of simple plant, steel structure and other infrastructure. Qb square pipe is generally used as the frame and purlin of the plant. C-shaped steel Steel is an important support for the plant, and H-section steel is used as load-bearing. Especially in recent years, a large number of small and medium-sized enterprises have started to build spacious and bright plants. If traditional buildings are built, the time is slow, the work progress is affected, and the investment is large. For some small and medium-sized enterprises, if the investment in the plant is too high, the capital will be produced after operation Serious impact. The plant built with qb square tube, C-section steel and H-section steel has the characteristics of time saving, money saving and fast use. Therefore, the sales of qb square tube, C-section steel and H-section steel have increased significantly in recent years and become the first choice for plant construction. Qb square tube, C-section steel and H-section steel are mainly used in the construction of simple plant, steel structure and other infrastructure The qb square tube is used as the frame and purlin of the plant. The C-shaped steel is used as the important support of the plant, and the H-shaped steel is used as the load-bearing. Especially in recent years, the time is slow, the work progress is affected, and the investment is large. For some small and medium-sized enterprises Said that if the investment in the plant is too high, C-section steel and H-section steel has the characteristics of time saving, money saving and fast use. Therefore, the sales of qb square pipe, becoming the first choice for plant construction. Large diameter qb square pipe plant is introduced Shao measures for effective wrinkle of seamless square pipe: check the wrinkle state, even when the wrinkle around the part is determined to be less than the clamping force, and the gradual increase of the roll gap force can be. When drawing the cone and hemispherical components, it should be increased to increase the inner diameter of the inner plate and the tensile stress of the wrinkle drawbead. Adopt the principle of loosening after tightening to loosen after tightening and ask Question.The common surface treatment of square pipe includes surface treatment, shot blasting treatment, manual mechanical treatment and flame treatment. The treated will be separated. ~ Mpa compressed air entrains abrasives, and the nozzle sprays to the steel surface at high speed. The impact and friction of abrasives remove the oxide scale, rust and dirt on the steel surface,Square tube nonferrous metals also known as non-ferrous metals, refer to metals and alloys other than ferrous metals, such as copper tin, lead, zinc, aluminum, brass, bronze, aluminum alloy and bearing alloy. In addition chromium, nickel, manganese, molybdenum, cobalt square tube, vanadium, tungsten, titanium, etc. are also used in industry. These metals are mainly used as alloy additives to improve the performance of metals. Tungsten, square tube titanium, molybdenum, etc. are mostly used to produce cemented carbide for tools. The above non-ferrous metals are called industrial metals. In addition, there are precious metals: platinum, silver and rare metals, including radioactive square tubes.Square pipe is the name of square pipe, that is, steel pipe with equal side length.
