When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size. 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 two surfaces of the flange are parallel to each other, making it easy to connect, process and install.Dresden,DresdenAlloy pipe 12Cr1MoVG price,There are five main guarantee measures for steel pipe welding. If these five aspects are guaranteed, the quality of galvanized pipe can also be guaranteed. Peak crackTukh,Dresden45 small diameter seamless pipe, Miscellaneous scab The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.At the same height, light I-beam has narrower legs, thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications, dimensions and relevant standards.

X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.Identification method of galvanized pipeThe 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.Quality Assurance,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.Introduction to product knowledge of alloy pipe:Alloy tube is widely used in our daily life which provides us with great assistance. So what industries are alloy tubes applied to? Let&#;s follow the steps of all manufacturers and have a look together:

In order to make the steel pipe workpiece have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and forming processes, heat treatment process is often essential. Steel is the most widely used material in the mechanical industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore, the heat treatment of steel is the main content of metal heat treatment. In addition, aluminum, copper, titanium and their alloys can also change their mechanical,X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water,DresdenHow much is No. 16 I-beam per ton, wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out. 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.The specification of I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is cm. 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 ~ mm, expressed as No. ~ No., and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system, cross rolling pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.Dresden,Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);Classification introductionI-beam
