China is a big steel country.
6Seamless pipe is a long steel with hollow section and no joints around it. There are more than production plants under more than companies in more than countries producing seamless pipes， including more than plants under more than companies in countries.
zBrosadStages needing attention in the production and manufacture of alloy tubes
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.
WFantinoGalvanized pipe is actually galvanized pipe. This is mainly because it increases the corrosion resistance of the steel pipe， so it is evenly coated with a layer of zinc. It can prevent the erosion of other chemicals such as and steam，Products Show and protect the steel strip. It is non-destructive and effectively prolongs its service life. Generally，MonctonC'est combien, 50 dollars?Plan de rectification des problèmes de l'industrie the steel strip purchased is rolled into a large number by the galvanized pipe manufacturer， so pay attention to it during storage.
Bx Seamless pipe mechanical properties， easy processing， etc;
The reinforced concrete surface reinforcement method has the advantages of simple construction technology and strong adaptability which can greatly improve the bearing capacity， flexural stiffness and ductility of the brick wall. At the same time， its natural frequency can be changed to improve its performance in normal use. It is mainly applicable to the solid wall， porous hollow brick wall and mm thick empty bucket brick wall with no cracks and shear in the original wall.
Pipelines of various specifications and models are complete.
uThe production process can be summarized as follows: pre leveling → finishing → straightening → post leveling. Flat steel / A / B steel with width of -， thickness of -， rectangular section and slightly pure edge. Flat steel can be finished steel，Products Show or it can be used as blank for welded pipe and thin slab for laminated thin plate.
W Seamless pipe is resistant to corrosion， acid， salt and atmospheric environment， high temperature， impact and fatigue， does not need regular maintenance， and the effective life is more than years;
MQuality inspection report Welded steel mesh， a new form of reinforcement， is especially suitable for large-area concrete engineering.
zLStraight 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，Products Show it is divided into annular welded pipe and special-shaped (square， pitch，MonctonC'est combien, 50 dollars?Plan de rectification des problèmes de l'industrie 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， continuous conveyor idler electric welded steel pipe， 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.
The zinc coating is thick， the crystallization is detailed， uniform and non porous，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd and the corrosion resistance is excellent;
If the steel pipe is not welded well， that is， if it is not welded， the welding conditions of steel mesh skeleton composite pipe shall be provided.

XPassivation treatment operation of alloy pipe
The smooth of steel pipe is mainly through tension reducing， which is a continuous rolling process of hollow base metal without center and tip. Under the condition of ensuring the capillary welding quality， the whole welded pipe is heated to more than ℃ by the welded pipe tension reduction process， and then rolled to finished pipes with various outer diameters and wall thicknesses by the tension reduction machine ( times in total). The fluid pipes produced by developed countries in the world have adopted the welded pipe smooth process in a large number of boiler pipes. With the development of society Domestic hot welded pipe has gradually formed a situation to replace smooth pipe.

cZ Because the zinc coating has excellent ductility， it can be formed by cold stamping， rolling， bending and so on without damaging the coating.
Generally， you can judge whether it is qualified from the appearance
