They are not affected by surrounding factors and processes, including corrosion.

1 The vertical of the processed reinforcement bar shall be divided into small sections as required.

omilkWhen we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, we will apply it,Products Show so it is very popular in the field. When people carry out the construction of alloy pipe project,GiguaniFinish rolled reinforcement manufacturerMake every effort to make deep processing production lines stable production and can improve the wear resistance of steel

After hot-dip galvanizing of steel structure, it is equivalent to one-time annealing treatment, which can effectively improve the mechanicalof steel matrix, eliminate the stress during steel forming and welding, and is conducive to turning of steel structure.

According to the historical records of the recent four years, the zinc price in the first quarter was generally higher than that in the whole year, and generally entered a wave of upward trend in the first quarter. However, zinc prices continued to decline in the first quarter of , and showed a trend of accelerating the decline day by day. There are two key reasons for the beginning of this year. First,Products Show the vicious change of the real estate industry has led to a rapid decline in the growth rate of China&#;s consumption of galvanized pipe and seamless steel pipe, and even a contraction month on month; Secondly, the blind expansion of galvanized pipe factory confused the sense of rhythm of supply and demand balance.

dThe shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.

IIdentification method of galvanized pipe

KQuality departmentGalvanized steel pipe: in order to improve the corrosion resistance of steel pipe general steel pipe (black pipe) shall be galvanized. Galvanized steel pipes are divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick and the cost of electro galvanizing is low.

lCWelded steel pipe, also known as welded pipe is a seamless steel pipe made of thick steel plate or hot-rolled strip by electric welding after coiling and forming, generally with a fixed length of m. Welded steel pipe has the advantages of simple production and processing process, many types, specifications and models, and less investment in machinery and equipment projects, but the general compressive strength is less than that of seamless pipe.

Seamless pipe is a long steel with hollow section and no joints around it. There are more than production plants under more than companies in more than countries producing seamless pipes, including more than plants under more than companies in countries.

Welded thin-walled pipe: mainly used for making furniture,Products Show toys, lamps,GiguaniFinish rolled reinforcement manufacturerMake every effort to make deep processing production lines stable production etc. In recent years, thin-walled tubes made of stainless steel strip are widely used, such as high furniture, decoration, fence and so on.

Process inspectionhFrom the comparison of the monthly summary apparent consumption data information of galvanized pipe and the real estate sales data information from to this year, they show the consistency of height width ratio, which not only shows a positive correlation in the overall new trend, but also significantly conforms to the fluctuation direction of the monthly development trend.

UWhether I-section steel is ordinary or light,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.

What are the quality protection measures for galvanized pipe during welding

wmilk Seamless pipe is resistant to corrosion, acid, alkali, salt and atmospheric environment, high temperature, impact and fatigue, does not need regular maintenance, and the effective life is more than years;

jGThe use of welded steel mesh in China is still in its infancy. At present the use of welded steel mesh in China accounts for less than one of the total amount of steel reinforcement. In the early s, steel welded mesh was listed as a key implementation project by the science and Technology Commission and the Ministry of construction, and specifications and procedures were formulated.

During the construction of building wall, cracks and hollows show that the construction materials are unqualified, and the construction personnel are poor. The external wall plastering adopts electric welding steel wire mesh, which can prevent cracking and strengthen the wall.
