There is a great demand for welded steel mesh in China&#;s market.

7Welded thin-walled pipe: mainly used for making furniture, toys, lamps, etc. In recent years, thin-walled tubes made of stainless steel strip are widely used, such as high furniture,Products Show decoration,BrossardCombien coûte 120 poutres I par mètreTraitement de l'effet de l'application fence and so on.

Hot rolled smooth round steel is structural steel, with chemical composition content of C carbon .%, Si silicon .%, Mn manganese %, s sulfur ≤ .%, P phosphorus ≤ .%, yield strength of mpa and tensile strength of MPa. High temperature continuous casting and rolling or ingot heating rolling. Soft, high ductility,.

UNarevaGalvanized pipe features:

EsFirst,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.

Since the s, with the rapid development trend of high-quality hot strip mill production and the development of electric welding and testing technology, the welding quality has been continuously improved, the types, specifications and models of welded steel pipes are increasing, and seamless pipes have been replaced in more and more industries. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the way of welding. Classified by production mode: classified by processing technology - electric arc welded pipe, resistor welded pipe, (high frequency, furnace welded pipe.

China is a big steel country.

mThe specification of pass design I-beam is expressed in cm of waist width. For example,Products Show the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~,BrossardCombien coûte 120 poutres I par mètreTraitement de l'effet de l'application expressed as No. ~ No., and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system, cross pass system and mixed pass system. In addition I-beam can also adopt special rolling method.

MSeamless 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.

LManagement DepartmentHigh percentage of metal strength.

aB The finished products shall be placed away from the processing site and stacked in the designated finished product warehouse. Ventilation and other facilities shall be provided in the storage environment.

Pure zinc layer is a plastic zinc layer in hot-dip galvanizing. Its properties are basically close to pure zinc and have ductility, so it is flexible.

Galvanized pipe features:

Installation conditionst Silicon; it can improve the hardness of steel,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd but the plasticity and toughness decrease. Electrical steel contains a certain amount of silicon, which can improve the soft magnetic properties

D Miscellaneous scab

The zinc coating is thick the crystallization is detailed, uniform and non porous, it is equivalent to one-time annealing treatment, which can effectively improve the mechanicalof steel matrix, eliminate the stress during steel forming and welding, and is conducive to turning of steel structure.

lODefect detection of seamless pipe

What is theof defect detection of seamless pipe? Magnetic particle testing or penetrant testing of seamless pipes can effectively find surface defects such as cracks, folds, double skin, hair lines, pinholes and so on. Because of its high detection sensitivity, magnetic particle detection method should be preferred for ferromagnetic materials. For non ferromagnetic materials such as stainless steel seamless pipe, penetrant testing method is adopted.
