H-shaped steel groove is deep and thick, and can withstand forces in two directions.Heating surface pipes, economizers, superheaters, reheaters, pipes for petrochemical industry, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)San Diego Las Vegas, we have produced galvanized pipe products for many years. Welcome friends who need to buy.The utility model has the advantages that the axial force of the roll is small, the axial movement is small, the working inclined plane is not required, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body.Zhenjiang,According to the theory of steel structure, the I-beam flange should be stressed, that is, the I-beam should be standing rather than lying down.What are the uses of I-beam?The 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.

Because the section size of ordinary I-beam and light I-beam is relatively large and narrow, the moment of inertia of the two main shafts on the section is quite different, the use of I-beam should be reasonably selected according to the mechanical properties chemical properties, weldability and structural size of I-beam. East West derusting: if the galvanized pipe surface is rusty, the manufacturer will choose East West derusting and polish it with a steel wire brushThe key purpose of grinding and polishing alloy pipe is to moisten the surface, and the relevant limit accuracy or appearance change is not easy to change.Workshop cost,The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, the surface of alloy pipe shall be clear of oil stains pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned,San Diego Las VegasGH536 alloy pipe, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film, which determines that the color of the surface layer has no change before and after passivation treatment, and the reproducibility of the solution is good.Plan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %, the interval is min. Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time, and the waist has an included angle with the horizontal axis.

Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materialsQuality documents, Remove defective pipes within the allowable length.The preparations for the construction of high-speed reinforcement mesh include the preparation and inspection of raw materials, and the preparation of construction equipment and engineering machinery.The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages.San Diego Las Vegas,C-section steel has uniform zinc layer, smooth surface,San Diego Las VegasHow to learn steel bar turning, strong adhesion no zinc scar, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, and the zinc content on the surface is usually -g /? It has long service life, corrosion resistance and durability. It is a kind of stronger protection.Pass design The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.
