With the development of steel structure buildings, only I-beam is not enough, that is, thickened I-beam, which is easy to lose stability for load-bearing columns.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.Lu Senjie,Lu SenjieHow much is 25 hot-dip galvanized pipe per meter, Whether the mesh size and wire diameter of electric welding mesh meet the standardsAlloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, whether it is fire water system software, or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system, alloy steel pipe stimulates important effects.Jonava Small longitudinal crackI-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRCKey technical characteristics of alloy pipe

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, double convex steel pipe, double concave steel pipe, melon seed steel pipe, conical steel pipe, corrugated steel pipe watch case steel pipe and others.I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Where can I find it?,Lu SenjieQuotation of high pressure alloy pipe,Classification introductionI-beam: national standard * what is the wall thickness of I-beamIt can withstand continuous moderate impact and can provide composite plates of various thicknesses

Stages needing attention in the production and manufacture of alloy tubesplan, Judged as failing. Polished stainless steel pipes shall be subject to internal inspection and strict manual selection by the steel pipe quality inspector through metal detector (or hydrostatic test),Lu SenjieHow much is a 219 welded pipe, and qualified products shall be packaged and delivered.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.Lu Senjie,H-section steelAlloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length, a large amount of liquid can be transported with an annular tube. In addition, when the circular cross section bears the internal or external axial working pressure, the bearing force is more symmetrical. Therefore, most seamless steel pipes are round steel pipes.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.
