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 ℃ ~ ℃) Judged as failing.Santa Clara,The pipeline shall be positioned according to the drawing design,Santa ClaraHow much is the rebar labor per square meter?, and the pipeline support shall be prefabricated according to the site conditions. Hang the wire from the th floor down and fix the support.I-beam is widely usedCamajuani,Key technical characteristics of alloy pipeI-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows: Peak crack

I-beam is widely usedSteel transfers heat excellently; Can withstand high temperature; Strong and strong materials; Probably a long time ago. In addition, there is the low cost of metal.It is often asked that the shape of I-beam is similar to that of H-beam. What is the difference between them? Many people can&#;t explain it in detail. Here is a detailed answer for you: many people think that I-beam is a domestic name and H-beam is a foreign name. In fact, this cognition is wrong. H-beam and I-beam are different in shape!Safety and health,When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, we will apply it, so it is very popular in the field. When people carry out the construction of alloy pipe project there are many things that must be paid special attention to. Let&#;s take you to know:The 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, or it can be used as blank for welded pipe and thin slab for laminated thin plate.Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlement

Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason, the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, when the billet section is narrow and wide I-beam is required to be rolled, when the billet is wide and small I-beam is required to be rolled, etc.recommend, damage and blanking, and increase the labor cost of material cleaning The tensile strength of seamless pipe is more than ~ times that of ordinary steel, the elastic coefficient is better than that of steel, and has good creep resistance, corrosion resistance and seismic resistance.All the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation showing a 'high mountain' shape.Santa Clara,Welded steel pipes need to be processed through various processes before application. The heat treatment of welded steel pipes is a very important link in the processing of welded steel pipes. Hot working is a metal hot working process in which metal materials are heated, insulated and cooled in a certain medium, and their metal properties are controlled by changing the metallographic structure on the surface or inside of the material. During the heating and cooling process of structural welded steel pipe workpiece,Santa ClaraWhat are the manufacturers of high frequency welded pipe, due to the inconsistency of cooling speed and time between the surface and the core, the temperature difference will be formed, which will lead to uneven volume expansion and contraction and produce stress, that is, thermal stress.I-beamThe specification of pass design I-beam is expressed in cm of waist width. For example, 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 ~,Santa ClaraT-welded pipe manufacturer, 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.
