It bears high internal working pressure.
5Galvanized pipe is a kind of light thin-walled steel pipe with hollow square section， also known as steel cold-formed profile. It is a section steel with square section shape and size， which is made of Q hot-rolled or cold-rolled strip or coil as the base material， cold bending and high-frequency welding. In addition to wall thickness thickening， the corner size and edge flatness of hot rolled extra thick wall galvanized pipe reach or even exceed the level of resistance welding cold formed galvanized pipe.

GBassalabeskaGalvanized 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.
KfSeamless pipe is made of steel block or solid pipe blank， and then made by hot rolling， cold rolling or cold dial. Seamless pipe plays an important role in Chinas steel pipe industry. Seamless pipe production processes are relatively rich， generally according to the corresponding steps of processing and production.
Acceptance according to standards
With the development of Chinas infrastructure，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd 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， housing and municipal engineering will increase exponentially.
qPatented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materials

qMFrom the situation of chiseling on site， the reinforcement mesh laid by the construction party is cm below the surface layer， which greatly exceeds the specification，الموقعأنابيب سبائكما هي اجراءات تشغيل وصيانة خط الانتاج؟ and then the crack resistance of the reinforcement mesh can be reduced. Because of the increasing temperature， the effect of thermal expansion and cold shrinkage and the characteristics of concrete， the cracking of surface layer is significant.
The multi-al combination of reinforcement mesh welding machine and reinforcement mesh row welding machine based on PLC basic control. At present， the full-automatic mesh welding machine has the characteristics of simple operation high control precision and easy to master the process of high-speed continuous welding.
The weight of seamless pipe is light，Products Show and its weight is only one fifth of that of anti steel.
Honesty and mutual benefitzAre there many welded types of mesh produced? According to the welding type and overall improvement， the difference between the reinforcement mesh and the welded mesh is not particularly large. It is still due to the scattered quality of the southern city. From the perspective of development to the longitudinal and transverse interleaving devices of the reinforcement mesh the bound or welded mesh has better application quality.
H H-section steel is an economic section steel with better mechanical properties than I-section steel. It is named because its section shape is the same as the English letter "H". The flange of hot rolled H-beam is wider than that of I-beam， with large lateral stiffness and strong bending resistance. Under the same specification， H-beam is lighter than I-beam.
High percentage of metal strength.

zWFirst， the two hole beam end space on the pier top shall be used to set the cast-in-situ transverse cantilever cantilever beam， one end is supported on the cantilever beam of side pier， and the other end is supported on the special buttress on the embankment， which is to avoid widening the abutment.
According to the shape of the product， special flour， welding or ordinary thread connection shall be used.
