H-section steel is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'. There is no slope on the inner side of the two outer edges of H-section steel, which is straight. This makes the welding and splicing of H-section steel simpler than I-section steel, better mechanical properties per unit weight, and can save a lot of materials and construction time.Pass designvictoria,Longitudinal welded pipe has the advantages of simple production process, high production efficiency, low cost and rapid development. The strength of spiral welded pipe is generally higher than that of straight welded pipe. It can produce welded pipe with larger pipe diameter with narrow blank, and welded pipe with different pipe diameter with blank of the same width. However,victoriaHigh pressure alloy pipe 15CrMoG, compared with the straight seam pipe with the same length, the weld length increases by ~ , and the production speed is low. Welded pipes with large or thick diameter are generally made of steel blank directly, while small welded pipes and thin-walled welded pipes only need to be welded directly through steel strip. Then after simple polishing, wire drawing is OK. Welded pipe is welded with strip steel,victoria38CrMoAl alloy pipe, so it is not as high as seamless pipe in its original position. Welded pipe process: uncoiling of raw materials - leveling - end shearing and welding - looper - forming - Welding - removal of internal and external weld beads - pre correction - induction heat treatment - sizing and straightening - eddy current testing - cutting - hydraulic inspection - Pickling - Inspection (strict control) - Packaging - delivery.Dry processing technology: after passivation treatment parts shall be dried with air compression or hot gas,What should we pay attention to in the production of alloy pipeSome applications of I-beam:Pass design

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:The correct and reasonable use of galvanized pipe can play a better role. The product can be widely used in the market because of its obvious performance advantages. Both strength and toughness are worth our choice. Let&#;s see what the specific uses are and what the acceptance standards are? Judged as failing.Administration,Alloy pipes are widely used in building materials, and the test standards of alloy pipes are also different. Alloy pipe has high hardness and can be used at many levels most of which is prestressed reinforcement. Where plastic deformation is not specified but compressive strength is specified, such stainless steel plate can be applied.The shape of I-beam is similar to that of H-beam. What is the difference between them?I-beam,victoriaQ345 straight seam welded pipe, also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.

I-beam: national standard * what is the wall thickness of I-beamService first, Frame line crack Remove defective pipes within the allowable length.The section of I-beam has good straight pressure and tensile resistance, but the section size cannot resist torsion because the wing plate is too narrow. On the contrary, H steel has its own advantages and disadvantages.
