It has iron zinc alloy layer and compact combination， which shows unique corrosion resistance in marine salt spray atmosphere and industrial atmosphere;
4Seamless pipe has a high position in steel pipe， which is applicable to all walks of life. Seamless pipe factories in China are widely produced. At present， the number of factories in China is also increasing every year， which is determined by the nature and production conditions of seamless pipe. The common production processes and processes are more complex.
wRiverside→ compared with the concrete structure， the I-steel structure can increase the service area by %，Products Show reduce the self weight of the structure by % - %，Minneapolis18 cotation I - beam SteelImpact sur la vie and reduce the structural design internal force.
It is divided into circular welded pipe and special-shaped (square， flat， etc.) welded pipe.
SGelfa Completion of pipeline trench ground; Bricklaying of pipe shaft is completed.
Du Main machines and tools
When excavating a tunnel in a stratum where the rock is not hard and complete， it is generally necessary to excavate a diversion pit (also known as pilot hole) and set temporary support.
General carbon steel wire sleeve (GB / t- is a steel pipe used to protect wires in electrical installation projects such as industrial and civil buildings and installation of machinery and equipment.
uBecause alloy pipe is a very unique pipe fitting， we must use appropriate methods to carry out installation in the case of installation， so as to ensure the performance index of the data. Generally when installing alloy pipes， we will use some flanges and elbows to fix them， so as to ensure that the raw materials can be fixed very well. Therefore， when we carry out use，Products Show we must ensure the quality of flanges and elbows， they must be installed together.
FWelded pipe refers to the steel pipe with joints on the surface， which is welded after the steel strip or steel plate is bent and deformed into circular， square and other shapes. The blank used for welded pipe is steel plate or steel strip. How can the steel strip or steel plate be welded together， and what are the welding skills?
Ttechnical service . the straight length of the hook of the surface mesh reinforcement at the grid support shall not be less than mm， and the bending diameter shall not be less than D (D is the reinforcement diameter).
fRHow are seamless tubes made?
With the development of Chinas infrastructure， the investment in infrastructure continues to grow; Implement the strategy of western development. Economic construction has entered a new stage， and the demand for welded steel mesh for capital construction such as power， transportation， water conservancy，Products Show housing and municipal engineering will increase exponentially.
Divided by weld -- straight welded pipe and spiral welded pipe.
Good reputationjThe use of welded steel mesh can make the project construction convenient. As long as the welded reinforcement mesh is laid as required the concrete can be irrigated， eliminating the links such as on-site cutting，Minneapolis18 cotation I - beam SteelImpact sur la vie placing and binding of reinforcement one by one.
TAccording to the national standard of hot rolled H-section steel in China (GB / t-， H-section steel is divided into narrow flange wide flange and steel pile， HK and Hu respectively. Narrow flange H-section steel is suitable for beams or compression bending members， while wide flange H-section steel and H-section steel piles are suitable for axial compression members or compression bending members. Compared with H-section steel， W， IX and iy are not as good as H-section steel under the premise of equal weight.
Square; Round; Fillet.
dRiversideWelded pipe refers to the steel pipe with joints on the surface， which is welded after the steel strip or steel plate is bent and deformed into circular， square and other shapes. The blank used for welded pipe is steel plate or steel strip. How can the steel strip or steel plate be welded together，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd and what are the welding skills?
uHWhat are the advantages of seamless pipe?
Galvanized 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.
