Construction preparation

6 If the surface of the welded pipe is rusty, we can polish the appearance of the welded pipe with a wire brush to prevent rust.

xBelize Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal, eliminate structural defects, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe,Products Show quenching machinery and equipment cannot be lacked. Therefore,هيليا38crmoal سبيكة أنابيباعتبارات الاختيار the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process it will eventually lead to bad harm to the product quality.

Thanks to a zinc tube, stand in the formation and development of painful microorganisms.

AKeynes It has iron zinc alloy layer and compact combination, which shows unique corrosion resistance in marine salt spray atmosphere and industrial atmosphere;

Material requirements


Belize



In building construction engineering, welded steel wire mesh is an essential heat preservation and crack prevention material. It has good performance and can take into account the unity between crack resistance and the requirements of face brick for base strength and the stability of heat preservation system.

qThe high-temperature passivation treatment of alloy pipe is to obtain the passivation treatment film by heating in the heat treatment equipment. Before passivation treatment,Products Show the surface layer of parts must be removed to remove waste. At a higher temperature, the passivation treatment film can be obtained according to the transformation temperature and time. The hue of passivation treatment film can refer to the annealing color of alloy pipe, and the main parameters of ambient temperature and time of heat treatment process can be selected.

GIt bears high internal working pressure.

FOK or not? According to the purpose, the welded pipe has general purpose and high temperature and high pressure. The pipe used in the latter is often special alloy steel. The problem of shrinkage cracks in the welding process and the mechanical properties of the pipe in the heat affected zone must be considered and solved,هيليا38crmoal سبيكة أنابيباعتبارات الاختيار and the mechanical properties of the pipe in the heat affected zone will not be greatly changed due to the influence of welding operation.

uS Spiral seam high-frequency welded steel pipe (sy- for general low-pressure fluid transportation takes hot-rolled steel strip coil as pipe blank and is often spiral formed at warm temperature. High frequency lap welding method is selected for welding spiral seam high-frequency welded steel pipe for general low-pressure fluid transportation.

Identification method of galvanized pipe

In hardware, you can choose an incomplete performance outside the product. Some construction experts claim that if there is a mechanical effect on these products, galvanized steel is more expensive than ordinary steel pipes, so installing them requires a lot of financial costs.

qBelize Pure zinc layer is a plastic zinc layer in hot-dip galvanizing. Its properties are basically close to pure zinc and have ductility,Products Show so it is flexible.

zG The rapid popularization and application of cold drawn ribbed bars and hot rolled grade III bars in China provides a good material basis for the development of welded mesh. The formal implementation of welding net product standards and application procedures has played a positive role in product quality and accelerating popularization and application.
