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.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,JukapaWelded pipe price in 2020, Japan iron and steel, etc.Jukapa,Various advantages of seamless pipe are widely used to manufacture structural parts and mechanical parts such as petroleum drill pipe automobile drive axle, bicycle frame, steel scaffold for construction engineering, improve material utilization, simplify manufacturing process, save materials and processing time, and are widely manufactured with steel pipe. Only by choosing suitable seamless pipes in different fields can we save resources and improve efficiency. In the future we will expand the research on seamless pipes and produce more seamless pipes with good performance. Please pay more attention to this website. I bring you new knowledge of seamless pipe. In recent years, seamless pipe is more widely used, the market demand of various industries is too large,JukapaHigh strength plastic alloy pipe, there are more and more enterprises producing seamless pipe, with large lateral stiffness and strong bending resistance. Under the same specification,The utility model has the advantages that the axial force of the roll is small, the axial movement is small, and the working slope is not required,Xhy- series high hardness alloy I-beam; Undertake drawings and process wear-resistant pipes（ Φ ≥mm）； Undertake the processing and production of vulnerable parts of cement machinery; Welding technology consultation and service; The wear-resistant layer of alloy wear-resistant plate of high chromium heap welding flux cored wire series is mainly high chromium, as well as manganese, molybdenum, niobium, francium and other components. The alloy carbide formed has strong stability at high temperature.The production process can be summarized as follows: pre leveling → finishing → straightening → post leveling. Flat steel / A / B steel with width of -,JukapaIs there any software for steel bar turning, 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.

The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Idler pipe: it is used for electric welding steel pipe of idler of belt conveyor. It is generally made of Q, QA, B steel and steel, with a diameter of -mm. There are certain requirements for pipe tortuosity, end face straightness with the center line and ovality. Generally, water pressure and flattening tests are carried out.b. The professional two-sided arc welding processing technology can complete the electric welding at a good position, which is not easy to have the disadvantages of staggered joint, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.Standard requirements,Application characteristics of I-beam:I-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.The import and export order of I-beam is generally based on the specifications required in use after determining the corresponding carbon structure steel (or low alloy steel) steel grade. Except for the specification number I-beam has no specific composition and performance series.

The import and export order of I-beam is generally based on the specifications required in use after determining the corresponding carbon structure steel (or low alloy steel) steel grade. Except for the specification number, I-beam has no specific composition and performance series.Service first,The utility model has the advantages that the axial force of the roll is small, the axial movement is small, and the working slope is not required, Seamless tube has high elasticity, can be reused on mechanical equipment, no memory, no deformation, anti-static.I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam.

Ordinary I-beam and light I-beam have formed national standards.Jukapa, Peak crack Hot push hole diameter. More sensitive applications and facilities of such methods require simplicity, low cost, easy maintenance, durable economic development and convenient product specification transformation. For example, the production of large diameter must be grooved pipe, elbow and similar products. You only need to add some spare parts. The expansion method of hot push can be used to process and manufacture large-diameter thick wall and thin alloy steel pipes, and can not exceed the working capacity of thick wall pipes of machinery and equipment.All the cracks occur at -mm away from the edge below the alloy pipe, showing a 'high mountain' shape.
