which is rolled by strip steel after process treatment. Many kinds of materials can form a square tube body. It is used for what purpose and where. Most square tubes are steel tubes, mostly structural square tubes, decorative square tubes and building square tubes. Generally, the strip steel is unpacked, leveled, crimped and welded to form a circular tube, which is rolled into a square tube and then cut to the required length. Usually 50 pieces per bag.

The iron filings and burrs on the cutting section shall be completely removed with a file or appropriate tools to prevent the iron filings and burrs from scratching the rubber O-ring and other accessories when connecting another part.

Newark.After chemical pickling, the square tube can be well protected by electrolysis. These are simple ways to prolong the service life of the square tube, We only need to treat according to these, so that the square tube can bring us great help in the use process. The cold galvanized square tube is the principle of cold galvanizing on the square tube used to make the square tube have corrosion performance. Different from hot-dip galvanizing, cold galvanizing coating is mainly carried out according to the electrochemical principle. Therefore, it is necessary to ensure the sufficient of zinc powder and steel, resulting in electrode potential difference, so the steel surface treatment requirements are very high.

Production standard classification square tube is divided according to production standard: national standard square tube, American standard square tube British standard square tube, European standard square tube and non-standard square tube.

.The cut-off position shall match the construction and site conditions, draw the determined position and mark the cut-off line with a meter ruler or other measuring tools.

The standard quantity of combustible and nonflammable square pipes is gbt97-1 (gbt97-199). The representative material is l245-l4 pipeline steel. Professional square pipes, square rectangular pipes, seamless square pipes, galvanized square pipes and galvanized pipes are of high quality and low price. They are fire-resistant, high temperature resistant, durable, safe and reliable. They are mainly used to transport combustible and nonflammable fluids with high requirements.

The strength of square tube refers to the function that the data of square tube are destroyed under static load (appropriate plastic deformation or fracture). Because the action forms of load include tension, contraction, meandering, shear and so on, because the strength is also divided into tensile strength, compressive strength, flexural strength, shear strength and so on. There is often a definite connection between various strengths. In normal use, tensile strength is often used as the fundamental strength gauge.

At present, square tubes also have many good properties, strong corrosion resistance and heat resistance, and are widely used in many scientific and technological fields. Therefore, even so wise people still do not stop studying the surface adhesion resistance of square tubes. Square tubes in the future will have better performance and make more important contributions to development.

According to metallographic classification, the annealed state of square tube: A. hypoeutectoid steel (ferrite + pearlite); b. Eutectoid steel (pearlite); c. Steel precipitation through a common square tube (pearlite + cementite); d. Ledeburite steel (pearlite + cementite).

Now, Fangguan can achieve such good results in the market, which is completely inseparable from the manufacturers' hard work in technology. I believe that the Fangguan market will be better and better in the future.

Installation works.In the heat exchange planning of metallurgy petrochemical and other occupations, there are various forms of heat exchangers, but the conventional heat exchangers have many disadvantages, difficult cleaning, large dust thermal resistance and so on, which can not meet the needs of production customers. The square tube heat exchanger based on square tube throat has the advantages of excellent heat exchange, easy cleaning, small dust thermal resistance and compact structure.

In order to ensure excellent coating quality, the coating is required to be firmly attached to the surface of the coated object. This depends on the quality of the coating itself; On the other hand, it depends on the quality of the coated surface treatment before construction. After various surface treatments, the coating quality and economic effect are very different.

Forging has many advantages in improving the plasticity of q355b square tube and improving the quality of steel, because the cast state of forged metal can be broken when forging q355b square tube. Therefore, there are forging workshops in some q355b square tube factories.

Classification of wall thickness square tubes are divided into super square tubes, square tubes and thin-walled square tubes according to wall thickness. Gbt6728-200gbt6725-200gbt3094-2000, JG 178-200 ASTM A500, JIS g34en10210 or technical agreement.

Honest service.Polishing process of square tube square tube is widely used in our life, so in the subsequent application process, the requirements for square tube in many places are also quite strict, especially for surface treatment. Today, we briefly introduce how the polishing process should be carried out.

Functional index analysis of q355b square tube - mechanical function of plastic square tube. Solid bending, as the name suggests, is to compact the bending. During real bending, the inner and outer rollers and the inner and outer walls of the pipe blank are compacted in both directions.

The square tube represents the large capacity of the metal material under the action of tension, and the calculation formula is: where: FB -- the strong force borne by the sample when it is broken, n (Newton); So -- original cross-sectional area of sample, mm2. Yield point (& sigma; s) the stress of metal material with yield phenomenon when the specimen can continue to elongate without increasing (keeping constant) the force during the tensile process, which is called the yield point.

Newark.Cold formed hollow section steel (American Standard) for cold pressed Q345B square tube (national standard) structure carbon steel cold-formed circular section and pressure welded Q345B square tube and seamless Q345B square tube (European standard) non alloy fine grain cold formed welded hollow structural profile (Japanese standard) angle steel Q345B square tube for general structure galvanized q355b square tube for low pressure fluid transmission, Standard No.: gbt3091-2008. Representative materials: q235q235bq345b, etc. it is mainly used to transport water gas, air, oil and water or steam. It is a special product manufacturing enterprise integrating R & D, and service. It has long been a professional square tube, square tube, seamless square tube, galvanized square tube and galvanized tube. Its purpose is only limited to general low-pressure fluid.

Square tube industry plays an important role in production and construction. Square pipe is a steel pipe made of a whole piece of metal without joints on the surface, which is called square pipe.

When the square tube is processed, it needs to be properly polished to ensure durability, including mechanical polishing, chemical polishing and electrochemical polishing.
