In view of the current market environment， the position of galvanized pipe is still relatively large. It is precisely because of this strong position that we can see this kind of building material in all walks of life， even in a field that seems to have little contact. It will be applied in many construction projects. At the same time， even in the depressed environment of the steel industry， the application situation and utilization rate of this kind of pipe are very high.
8Galvanized pipe can be seen from its name. It is a square pipe type. Many materials can form galvanized pipe body. It is used for what purpose and where. Most galvanized pipes are steel pipes. After unpacking， leveling，Products Show crimping and welding，EspazaAlloy pipe 12Cr1MoVG priceFull of praise they form round pipes， which are rolled into square pipes， and then cut into the required length. Generally， most of them are in large specifications， ranging from * * .- to * * - Galvanized pipes are divided into structural galvanized pipes， decorative galvanized pipes， architectural galvanized pipes， mechanical galvanized pipes， etc.

What is galvanized pipe
BPort NatalesIn 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.
Uc Cleaning: first， clean the grease， dust and other substances attached to the surface of the galvanized pipe after cleaning.
The first is people. Human factors are the control focus of welding. Therefore， before welding， welders with skilled technology and welder certificate shall be selected for necessary technical training and disclosure. It shall not be replaced at will to ensure the relative stability of the welders welding the pipeline.
Reinforcement mesh is manufactured by automatic and intelligent production line under the strict quality control of the factory. Grid size， reinforcement specification and quality are strictly controlled. The longitudinal and transverse bars of the reinforcement mesh form a network structure， so it has good bonding and anchorage with the concrete， and the load is evenly distributed which obviously shows the seismic crack resistance of the reinforced concrete structure.
yAt present， there is still a big gap in the production technology of C-section steel between China and foreign countries.
D Completion of pipeline trench ground; Bricklaying of pipe shaft is completed.
Jnew productFirst，Products Show we can clean the outer surface of the welded pipe with solvent or emulsion. This method is very effective for cleaning the oil stain， dust and other organic matters on the surface of the welded pipe.
sEAccording to the shape of the product，EspazaAlloy pipe 12Cr1MoVG priceFull of praise special flour， welding or ordinary thread connection shall be used.
Blanking shall be carried out according to the design and site， and the gap between the two pipes is mm ~ mm and then weld.
According to the process， resistance welded pipe (high frequency and low frequency) it is divided into arc welded pipe， gas welded pipe and furnace welded pipe.
Product rangecFirst， the two hole beam end space on the pier top shall be used to set the cast-in-situ transverse cantilever cantilever beam， on which the prefabricated micro bending plate shall be installed. The second is to erect prefabricated sidewalk beams in the cantilever part of the cantilever beam. The sidewalk beams of bridge openings on both sides are longer than the main beam， one end is supported on the cantilever beam of side pier，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd and the other end is supported on the special buttress on the embankment， which is to avoid widening the abutment.
UAt present， there is still a big gap in the production technology of C-section steel between China and foreign countries.
The electric welding reinforcement mesh can reduce the damage and consumption to the reinforcement processing process. According to statistics， after deducting the steel consumption increased by unit lapping， it can also save about % of the steel. After it is transported to the site according to the construction degree of the project， it can be hoisted to the working face. There is no need to set a reinforcement processing site on the site， which saves the site and increases the management level of the site. At the same time， it can also solve the problems of noise pollution caused by straightening reinforcement.
lSan Juan DiosSeamless pipe has a high position in steel pipe， and there are many large factors. The main usage has accounted for more than %， 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.
pKIn order to improve the corrosion resistance of steel pipe， the general steel pipe (black pipe) is galvanized. The galvanized pipe is divided into hot-dip galvanizing and electric steel zinc. The hot-dip galvanizing layer is thick and the cost of electric galvanizing is low， so there is galvanized pipe.
The preparations for the construction of high-speed reinforcement mesh include the preparation and inspection of raw materials， the inspection and acceptance of the lower layer of the pavement， and the preparation of construction equipment and engineering machinery.
