Greatly reduce the environmental pollution caused by abrasion, and increase the labor cost of material cleaningSome applications of I-beam:Ottawa, As long as the pipe material is high-strength alloy steel,OttawaA335p9 high pressure alloy pipe, including alloy steel pipes with temperature resistance, pressure resistance, wear resistance and low temperature resistance, the welding process shall be focused on preventing the tendency of martensite structure and cracks due to welding high-temperature operation. The general process requirements are that the welding rod shall be selected and baked as required and sent to the welder for use. The oil and water shall be removed before welding on both sides of the weld Rust and sundries shall be removed and cleaned. The welding line energy shall be as small as possible to minimize the swing during the welding process. The arrangement of the last weld shall have annealing effect on the heat affected zone as far as possible. Slow cooling after welding, cover with asbestos cloth, etc.The 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.Tournai,Stages needing attention in the production and manufacture of alloy tubes Remove defective pipes within the allowable length.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.

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, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.In hardware, you can choose an incomplete performance outside the product. Some construction experts claim that if there is a mechanical effect on these products, they are not suitable. At least this product is impossible.The side length of I-beam is small and the height is large, so it can only bear the force in one direction.Fair price,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.I-beamAt the same height light I-beam has narrower legs, and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam, dimensions and relevant standards.

C-section steel has uniform zinc layer, smooth surface, strong adhesion, no zinc scar, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, and the zinc content on the surface is usually -g /? It has long service life,Ottawa15CrMoG seamless pipe factory, corrosion resistance and durability. It is a kind of stronger protection.Respect for customers,Performance parameters and application scope of I-beam Steel mesh guardrail (steel mesh fence) steel mesh guardrail refers to the guardrail made of steel mesh. It is stronger and more durable than the guardrail made of electric welding mesh, steel mesh, hook mesh etc.,OttawaHot dip galvanized welded pipe manufacturer, but its cost is much higher, and it is rarely used under normal circumstancesb. 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.Ottawa, cold rolling by few station mandrel mill, cold rolling by three high limited mandrel mill and cold rolling by fluctuating mandrel mill. In this way, the advantages of high efficiency, low metal material consumption, excellent product quality and excellent automatic control system are more and more widely used. The competitive advantage of the latter one is low cost and short whole process. It is suitable for the processing and manufacturing of CrMoG alloy pipes with large quantities, small types, multi specifications and high precision. Therefore, it is widely used Frame line crackAll 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.
