Straight seam welding is adopted for larger diameter welded pipe， and spiral welding is mostly adopted for large diameter welded pipe; According to the top appearance of seamless steel pipe， it is divided into annular welded pipe and special-shaped (square， pitch， etc.); according to different materials and main purposes， it is divided into mining anti liquid transportation welded steel pipe hot-dip galvanized welded steel pipe for bottom pressure liquid transportation，Products Show continuous conveyor idler electric welded steel pipe，ليسبريدج ›Q345B مصنع أنابيب الصلب غير الملحومةتؤثر بشكل خطير على هامش ربح الصناعة etc. it is arranged from small to large according to diameter * wall thickness according to the specification， model and dimension table in the current standard.
2Installing the pipe structure means the complexity of some elements.
wFredericktonBecause alloy pipe is a very unique pipe fitting， we must use appropriate methods to carry out installation in the case of installation， 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， we must ensure the quality of flanges and elbows， so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline，Products Show and the anchorage length of the reinforcement is the same as that of the reinforcement， without hook.
JCaibarien The 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.
TaIdentification method of galvanized pipe
The seamless pipe produced by the seamless pipe manufacturer is a long seamless pipe without any joints around and with hollow section. The thicker the wall of this product produced by the manufacturer， the higher the use value and economic value of this product. If its wall thickness is thinner， its processing composition will increase significantly， Secondly， the product technology produced by this seamless pipe manufacturer often determines its limitations.
Welded thin-walled pipe: mainly used for making furniture， toys，Products Show lamps， etc. In recent years，ليسبريدج ›Q345B مصنع أنابيب الصلب غير الملحومةتؤثر بشكل خطير على هامش ربح الصناعة thin-walled tubes made of stainless steel strip are widely used， such as high furniture decoration， fence and so on.
tAs shown in the name， I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination generally :， which makes the outer flange thin and the inner flange thick. Therefore， the section characteristics of I-beam in the two main planes are very different， and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market， the structure of the I-beam has determined its torsional performance.
O After the above process，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd and the internal and external surface finishing of pipelines meets the mirror standard (i.e. sanitary standard).
Jnew productIn addition， galvanized steel is more expensive than ordinary steel pipes， so installing them requires a lot of financial costs.
vXPrecautions for galvanized pipe storage
It is also divided into general welded pipe， galvanized welded pipe， oxygen blowing welded pipe， wire sleeve， metric welded pipe， idler pipe， deep well pump pipe， automobile pipe， transformer pipe， electric welding thin-wall pipe， electric welding special-shaped pipe， scaffold pipe and spiral welded pipe.

I Judged as failing.
The grid spacing size and number of reinforcement of electric welding reinforcement mesh are correct， which overcomes the phenomenon of large spacing size error and missing binding and buckle of binding quality caused by manual placement of reinforcement in traditional manual binding. The welded steel mesh has high strength and good elasticity. When pouring concrete， the steel bar is not easy to be partially bent and does not change. Because it is considered that the longitudinal and transverse steel bars are spot welded into a mesh structure， so as to achieve the goal of side-by-side average stress and bonding anchor.
