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

One of the steps that are prone to defects in the production of square tubes is heat treatment and the other is tensile treatment. Today we need to know the latter. Maybe some people will have a lot of questions about why square tubes are prone to defects in tensile. Now let's analyze the specific causes of defects.

AzZuwaytinah.Solution treatment and nondestructive testing sand rolling treatment and sand blasting treatment many manufacturers in the market do not do solution treatment and 100% penetration nondestructive testing, and many of them use sand blasting instead of sand rolling. After these steps are omitted,AzZuwaytinahHot dip galvanized pipe factory, the cost is greatly reduced.

When we understand the causes of defects in the drawing process of q355b square tube, we should constantly improve the technology in the subsequent production process, so that we can reduce the occurrence of defects.

.Therefore, the drawing process of square tube is quite meticulous. For a long time, square tube, square tube, seamless square tube, galvanized square tube, galvanized tube and other brand products are provided with complete designated products and quality assurance. In the process of continuous development, square tube has also been processed more rigorously.

Tensile strength: 490-675 yield strength: & Ge; 345 elongation: & Ge; 22 mechanical properties of seamless pipe: tensile strength: 490-675 yield strength: ≥ 345 elongation: & Ge; 21 mechanical properties of seamless pipe: tensile strength: 490-675 yield strength: ≥ 345 elongation: & Ge; 21 mechanical properties of seamless pipe: tensile strength: 490-675 yield strength: ≥ 345 elongation: & Ge; 22 mechanical properties of seamless pipe: tensile strength: 490-675 yield strength: ≥ 345 elongation: & Ge; 22 square tube belongs to low alloy series. It is one of the materials of seamless steel pipe. In low alloy materials, this material is ordinary. Square tube used to be called Q345B square tube.

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.

Square pipes are mainly used in engineering buildings, glass curtain walls door and window decoration, steel structures, machinery, automobiles household appliances, shipbuilding, containers, electric power, agricultural construction, agricultural greenhouses, bicycle frames, motorcycle frames, shelves, fitness equipment, leisure and tourism, steel furniture various specifications of oil casing, oil pipes and pipeline pipes, water, gas, sewage, air Heating and other fluid transportation, fire fighting and support, construction and other fields.

For gas transmission: gas, steam and liquefied petroleum gas.

You can really feel that the square tube is widely used in the development, and q355b square tube factory continues to extend in the technical level, which makes the current square tube develop more widely.

offer.The standard number of spiral square pipe (standard of the Ministry of petroleum) for low pressure transmission is syt5037-2008. The representative materials are q235bq345b and other carbon steel materials. It is mainly used for low-pressure transmission of water, heating and other pipelines.

The researcher's test before using the strip thinning drawing also confirmed that using the strip thinning drawing can greatly reduce the large value of tangential residual stress of the drawn parts and effectively prevent the occurrence of longitudinal cracking. According to different deformation degree and original sheet thickness, the appropriate thinning coefficient & psi is selected; N (generally 0.9t ~ 0.95t), if & psi; If n is too small,AzZuwaytinah120654 galvanized square tube, the deformation stress will increase sharply, resulting in the fracture of the bottom of the drawing part.

Application of square tube products: for mechanical equipment, solar energy equipment, steel structure, automobile parts, bridge ground pile, guardrail and ship internal structure.

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.

Quality assurance.According to production, cold-rolled tubes, cold drawn tubes, tubes, pipe jacking, etc. According to the section shape, the square tube is divided into round and special-shaped. The special-shaped tube has many complex shapes, such as square, oval angular, angular, melon seed, star and winged tube.

Hundreds of degrees Celsius, which can save energy.

Galvanized q355b square pipe for low pressure fluid transmission, Standard No.: gbt3092-2008. The representative materials are the same as above. It is mainly used to transport low-pressure fluids such as water,AzZuwaytinahGalvanized special-shaped square pipe, gas, air and oil and add water or steam. The surface of square pipe shall be hot galvanized or cold galvanized.

AzZuwaytinah.First, remove the deposits on the surface of the square pipe surface with copper wire brush. Use the perfume oil or other scrubbing oil on the surface layer, or use phosphate or chromate solution brush, spray or dip coating. After the fixed reaction time, rinse the acid solution with plenty of fresh water on the surface.

The square tube will be tested in many aspects of its performance in the process. Each test is for the square tube to have a good performance in practical application. So what are the different properties of square tubes? Next, I'll introduce the characteristics of the lower tubes in terms of mechanical properties.

For seamless q355b square tubes, there is a certain hardness, so it is necessary to test the mechanical properties of seamless q355b square tubes.
