7Galvanized 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， crimping and welding， they form round pipes， which are rolled into square pipes， and then cut into the required length. Generally，Products Show there are galvanized pipes in each package. In terms of spot，Canada40 Cr tubes en alliage de grand diamètreFacteurs affectant la vitesse de transformation 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.
kHalifaxAdvantages of using I-beam: reduce maintenance cost， reduce downtime， reduce wear， such as the reuse rate of mesh and reinforcement installed in the current mesh production company and the treatment of corrosion. The design strength value of circular reinforcement and the design strength value of welded reinforcement mesh. According to the equal strength substitution principle and considering comprehensive factors，Products Show the use of steel welded mesh plate can save the use of steel bars in the steel welded mesh plate factory. And the reinforcement mesh needs to be processed after it is shipped to the site， so there is no wear.
NSaniaThe advantage of the reinforcement mesh system is ecological. It is filled with natural stone materials. There is a gap between the stone materials to allow plants to grow in it. It can also plant plants on it. It has the dual effects of engineering slope protection and plant slope protection. The Ecological Grid mat is a combination with a height of cm ~ cm， mostly a multi grid box separated by spacer mesh.
XwGalvanized pipe has excellent corrosion resistance. Compared with traditional steel， its application life is longer. Secondly this kind of pipe has strong resistance to baking. In case of critical situation， it will not lead to the collapse of building structure in a short time. In addition， this kind of pipe also has a practical advantage， that is， it is more convenient and lighter when carrying out the construction and installation. The operators save time and labor when carrying out the construction， and the operation efficiency has been greatly strengthened. In this regard， it is not difficult to understand why the galvanized pipe is so favored by various construction units.
There is a great demand for welded steel mesh in Chinas market.
Compared with manual binding，Products Show welded steel mesh can reduce the occurrence of cracks by more than %. The use of reinforcement mesh can make the project construction faster. As long as the reinforcement mesh is laid as required， the concrete can be poured，Canada40 Cr tubes en alliage de grand diamètreFacteurs affectant la vitesse de transformation eliminating the links of reinforcement on-site cutting， placing one by one and binding. It can save % - % of working hours， greatly accelerate the construction progress and shorten the construction cycle.
mI-beam， also known as steel beam， is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.
PAccording 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 ，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd and showed a trend of accelerating the decline day by day. There are two key reasons for the beginning of this year. First， the vicious change of the real estate industry has led to a rapid decline in the growth rate of Chinas consumption of galvanized pipe and seamless steel pipe， the blind expansion of galvanized pipe factory confused the sense of rhythm of supply and demand balance.
Ghow much In order to ensure the welding quality of pipes， welders shall be trained， tested and qualified. In addition to the basic theory， the welder should consider the operation skills. The pipe welding process may include several postures of overhead welding， vertical welding and overhead welding (when the pipe cannot rotate). The size of current should be selected to take into account the formation of vertical welding and overhead welding (some pipes are not very large， and the current cannot be adjusted in the middle of one formation). In the process， the stability and formation of arc should be controlled， It can swing properly， and the forming shall be well combined with the necessary swing.
xIWhen the beam width is small， the reinforcement shall be bent.
When the end span plate is connected with the concrete beam for structural reinforcement， the length of the surface mesh reinforcement extending into the beam shall not be less than d. When the beam width is small， the extended reinforcement shall be bent . When the perimeter of the floor is poured integrally with the concrete beam or wall， the length of the surface mesh reinforcement extending into the beam shall not be less than the anchorage length of the small reinforcement required by the standard (without transverse reinforcement) when the beam width is small， the extended reinforcement shall be bent.
Straight seam electric welding steel pipe (yb- is a steel pipe whose weld is longitudinally parallel to the steel pipe. It is usually divided into metric welded steel pipe， welded thin-walled pipe， transformer cooling oil pipe， etc.
Create brilliancepGalvanized pipe features:
XThe 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.
The storage of galvanized pipes should pay attention to several points. The first is the storage location. It cannot be placed in the open air because in the open air， not only the safety of various products such as theft， but also corrosion problems will occur. Open air sites are vulnerable to various extreme weather conditions. Large amounts of rain or snow will erode the zinc coating on the surface to the greatest extent which may lead to rust of the product. The second is the details of storage. It is not directly exposed to the sun. It shall be cooled and dried and shall not be stored with corrosive articles.
nHalifaxAcceptance according to standards
eO The zinc layer obtained by electroplating is relatively pure， alkali and other fog， and can effectively maintain the steel matrix;
Galvanized pipe refers to the shape and high frequency of hollow square steel pipe welded by the back of the steel pipe during the hot rolling or cold rolling of galvanized steel plate or cold bending of galvanized steel plate， or before the galvanization of cold hollow pipe. Galvanized. Galvanized square pipe can be divided into hot galvanized pipe and cold galvanized pipe from the production process. This is because the two galvanized pipes are different， which also leads to many different physical and chemical properties.
