CharlottetonWelding video of galvanized square pipeScope of application and problems encountered in use

Stage ( & mdash; )Improve the positioning and pre bending steps, if necessary, to ensure that the web hunting problem does not occur when pressing parts. Change the shape of the surface pressure of the material to ensure the quality of the parts and avoid the non movement of the surface shape of the roll gap, resulting in uneven walking feeding.Charlotteton,Square tubes are low alloyClassification of square pipe material square pipe is divided into ordinary carbon steel square pipe and low alloy square pipe according to material. Ordinary carbon steel is divided into Q Q q SS, # steel # steel, etc; Low alloy steels are divided into q Mn, Q, St-, etc.Esperanza,The local heat release in the welding process of square tube can reduce the heat affected zone, avoid the micro of thermal sensitive materials, and maintain the properties of materials.High density may not be obtained by simple pressurization, and insulation shall be carried out at the same time.Fatigue strength, plasticity and hardness discussed above are indicators of the mechanical properties of metals under static load. In fact, many machine parts work under cyclic load, under which fatigue will occur.

The second is the pickling of the square pipe. Both chemical and electrolytic methods are used when pickling the square pipe. These two methods can remove the oxide skin of the square pipe.Galvanized qb square pipe for low pressure fluid transmission, Standard No.: gbt-. The representative materials are the same as above. It is mainly used to transport low-pressure fluids such as water, gas, there will be thinning, so manufacturers usually use thick spot pipes. If thin raw materials are used, the products produced must be unqualified. Generally there are about wires thinned. If the technology is not good or the drawn pipe is used, the thickness is significantly lower than the standard.Quality risk,The load of impact toughness acting on the parts at a great speed is called impact load. It is specialized in products and renewable resources. Its business includes: square tube, square tube seamless square tube, galvanized square tube and galvanized tube. The ability of metal under impact load is called impact toughness.With the improvement of production quality, 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, open square pipe rectangular tube and complex section square tube & mdash& mdash; Surface treatment classification of flower shaped square pipe, corrugated square pipe and special-shaped square pipe square pipe is divided into hot-dip galvanized square pipe, electro galvanized square pipe, oil coated square pipe and pickling square pipe according to surface treatment. Square pipe is classified according to purpose & mdash& mdash; Square tubes for decoration, machine tools and equipment, machinery industry, chemical industry, steel structure, shipbuilding, automobile, steel beam and column and special purpose are classified by wall thickness & mdash& mdash; Super square tube, square tube and thin-walled square tube plasticity refers to the ability of metal materials to produce plastic deformation (deformation) without deformation under load.

The advantage of empty bending is that it can bend the side length when the real bending cannot be carried out,The reason why it is divided into two types is that chemical cleaning can only clean the surface very thoroughly,CharlottetonGalvanized steel square pipe factory, and it is difficult to achieve the desired results in some fine cracks.Square pipe is an important type of square pipe, which has great similarities with seamless steel pipe, but it is different. Square pipe is of great use in square pipe, which is generally used in the field of building materials and pipes. Today we tell you about the painting of square pipe. In fact, most manufacturers need to do this function, not only painting but also galvanizing. Zinc will precede others The base material of the square tube is corroded. If painting doesn't become your business, you should pay a sum of money. If painting, you are recommended to brush zinc rich primer, because other paints will corrode quickly, and then continue to corrode your galvanized layer, so as to achieve the finish coat on the zinc rich primer. In fact,Generally, chemical and electrolytic methods are usedImprove the positioning and pre bending steps, if necessary,Charlotteton6 points galvanized water pipe, to ensure that the web hunting problem does not occur when pressing parts. Change the shape of the surface pressure of the material to ensure the quality of the parts and avoid the non movement of the surface shape of the roll gap, resulting in uneven walking feeding.For gas transmission: gas, steam and liquefied petroleum gas.
