KonumiQ345B welded pipe manufacturerPerformance and precautions when using

Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time, and the waist is parallel to the roll axis.d. All machines and equipment in a production line can connect with the software of the computer data collection system to complete the timely transmission of data information,When the beam width is small, the reinforcement shall be bent.Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.Toronto,Defects of alloy pipe and solutions: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,KonumiI-button, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned, 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.Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.

Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.Defect detection of seamless pipea. In the forming process, the thick steel plate has uniform deformation, especially in the production and manufacturing of steel structure design grade thick wall pipe specification and model of diameter and wall thickness especially medium diameter small thick wall pipe, which has incomparable advantages of other processing technologies, and can meet a large number of customer regulations on the specification and model of alloy pipe.Welcome calls ,I-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.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.Introduction to product knowledge of alloy pipe:

I-beam is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Baotou Iron and steel, Shangang, huangte, Maanshan Iron and steel, Xuanhua Iron and steel, Japan iron and steel, etc.Honesty and mutual benefit, The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge. If the surface of the welded pipe is rusty, we can polish the appearance of the welded pipe with a wire brush to prevent rust.H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam,Konumi35CrMo thick wall alloy pipe, channel steel and angle steel.Konumi,Alloy pipe is a kind of seamless steel pipe. Alloy pipe is divided into structural seamless pipe and high-pressure heat-resistant alloy pipe. It is mainly different from the production standard and industry of alloy pipe. Annealing and tempering of alloy pipe changes its mechanical properties. Meet the required processing conditions. Its performance is higher than that of ordinary seamless steel pipe, its utilization value is higher, the chemical composition of alloy pipe contains more Cr, and its performance of high temperature resistance, aerospace, chemical industry, electric power, boiler and other industries because the mechanical properties of alloy tubes change and are easy to adjust.Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.I-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.
