There is a great demand for welded steel mesh in China&#;s market.

8 Tungsten; can improve the red hardness and thermal strength of steel, and can improve the wear resistance of steel

sLongueuil The utility model has the advantages that the axial force of the roll is small, the working inclined plane is not required, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body.

Spiral welded steel pipe (sy- for pile is made of hot-rolled steel strip coil as pipe blank, often warm spiral forming,Products Show double-sided submerged arc welding or high-frequency welding. It is used for foundation pile of civil building structure,Winnipeg42CrMo tube en alliage à paroi épaisseBon sens de l'utilisation des outils wharf, bridge, etc.

Ow Whether the mesh size and wire diameter of electric welding mesh meet the standards

When the end span plate is connected with the concrete beam for structural reinforcement, the extended reinforcement shall be bent . When the perimeter of the floor is poured integrally with the concrete beam or wall, the length of the surface mesh reinforcement extending into the beam shall not be less than the anchorage length of the small reinforcement required by the standard (without transverse reinforcement) when the beam width is small, toys the extended reinforcement shall be bent.

Welded thin-walled pipe: mainly used for making furniture, lamps, etc. In recent years, thin-walled tubes made of stainless steel strip are widely used,Products Show such as high furniture, decoration, fence and so on.

p Mixed pass system. According to the characteristics of rolling mills and products, in order to give full play to the advantages of their respective systems and overcome their disadvantages mixed pass system is often adopted, that is, the combination of more than two systems. For example, straight leg cross rolling pass system is adopted for finished hole and front hole of finished product, and bent leg cross rolling system is adopted for other passes; or direct rolling system is adopted for rough rolling hole and straight rolling system is adopted for the last ~ finish rolling holes Leg oblique tie hole, etc.

YThere are many types of galvanized pipes, mainly including cold plated seamless pipes and hot-plated seamless pipes. But now the previous one is no longer used. The hot-dip seamless tube is still in use. Hot dip galvanized pipe is mainly used for steel pipes with low pressure fluid such as water and gas. When in use,Products Show if in normal working environment, the thickness of galvanized layer of hot-dip galvanized seamless steel pipe is up to μ M above,Winnipeg42CrMo tube en alliage à paroi épaisseBon sens de l'utilisation des outils and it has been used safely for about years. It can be seen that its service life is very long. Of course, when purchasing, it is basically cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank. In order to ensure the quality, electro galvanizing will not be used. There are also some small enterprises in the market. They will use electro galvanizing in production. In this way, although it is much cheaper in price. However, the quality is very good when used, and it is also easy to have problems.

gK Straight seam electric welding steel pipe (yb- is a steel pipe whose weld is longitudinally parallel to the steel pipe. It is usually divided into metric welded steel pipe, welded thin-walled pipe, transformer cooling oil pipe, etc.

The third is the welding machine, which must ensure reliable performance and meet the process needs; The welding machine must have qualified ammeter and voltmeter to ensure the correct implementation of welding process. The welding cable shall not be too long, and the welding parameters shall be adjusted when it is too long.

Product rangevGalvanized pipe is actually galvanized pipe. This is mainly because it increases the corrosion resistance of the steel pipe, so it is evenly coated with a layer of zinc. It can prevent the erosion of other chemicals such as and steam, and protect the steel strip. It is non-destructive and effectively prolongs its service life. Generally, the steel strip purchased is rolled into a large number by the galvanized pipe manufacturer, so pay attention to it during storage.

KC-section steel has uniform zinc layer, smooth surface, no zinc scar, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, and the zinc content on the surface is usually -g /? It has long service life, corrosion resistance and durability. It is a kind of stronger protection.

cLongueuil Spiral welded steel pipe (sy- for pile is made of hot-rolled steel strip coil as pipe blank, often warm spiral forming, double-sided submerged arc welding or high-frequency welding. It is used for foundation pile of civil building structure, wharf, bridge, etc.

hGIf the steel pipe is not welded well, that is, if it is not welded the welding conditions of steel mesh skeleton composite pipe shall be provided.

There shall be no bending at the welded junction, and there shall be no staggered joint during assembly. Electric welding positioning is generally spot welding. After inspection and straightening, the free conversion method shall be used for welding as far as possible.
