Transformer tube: it is used to make transformer heat dissipation tube and other heat exchangers. It is made of general carbon steel. Flattening, flaring zigzag and hydraulic tests are required. Steel pipes are delivered in fixed length or double length, and then extend it to the rolling mill. This method has fast production speed, but has high requirements for the workability of the blank. It is mainly suitable for the production of carbon steel and low alloy steel pipes. The extrusion law is to pierce the blank or ingot with a punch, and then squeeze it with a steel pipe with an extruder. The efficiency of this method is lower than that of cross rolling method. It is suitable for producing high-strength alloy steel pipe. The billet or ingot must be heated before cross rolling method and extrusion method. The produced steel pipe is called thermal correlation. Steel pipes produced by hot working can sometimes be cold worked as needed. There are two methods of cold working. One is cold drawing. In other words, pull the pipe to the pipe and tilt it to make the steel pipe gradually thinner and longer. Another method is cold rolling. The method of applying the hot smoke invented by brother to cold processing. The cold working of seamless pipe can improve the dimensional accuracy and finishing of steel pipe,Products Show and improve the mechanical properties of materials.

vAntigua and Barbuda Stages needing attention in the production and manufacture of alloy tubes

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?

GKondalaMost of the original bridge decks lack a stable and solid base course with poor integrity. It is necessary to clear the original bridge deck,سانت بطرسبرغ30crmo سبيكة أنابيبإبداعي excavate part of the gravel cushion (if it is non gravel filler, replace it with gravel filler and tamp it), and then pave cement stabilized gravel base course on which reinforced concrete bridge deck is poured. The longitudinal reinforcement and transverse reinforcement of the reinforcement mesh of the bridge deck pavement form a network structure, so it has good bonding and anchorage with the concrete, and the load can be evenly dispersed, which obviously improves the performance of the reinforced concrete structure. According to the practice test, the welded reinforcement mesh laid on the road can reduce the occurrence of cracks than the manual binding mesh.

FyIn 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.

Classification by use

The surface of cold galvanized layer is smooth,Products Show dense and uniform. It has good mechanical properties and corrosion resistance. The consumption of hot-dip galvanized coating is between % - %. The galvanizing process is complex, so the thin-walled pipe shall be galvanized. The zinc coating has strong protection and corrosion resistance.

oXhy- 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 surface coating and double-sided coating is different, as well as manganese, molybdenum, niobium, francium and other components. The alloy carbide formed has strong stability at high temperature.

SThe whole structure is composed of zinc and quaternary crystals, forming dense crystals and barrier layer on the plate, which effectively prevents the penetration of corrosion factors. From the point of view of the strong zinc corrosion resistance of the barrier layer, when the zinc sacrificial anode is at the forefront of protection, the scratches and scratches of some coatings and the insolubility of zinc oxide layer play a protective and blocking role.

Mwhere Platform reinforcement mesh is a widely used reinforcement mesh product,Products Show such as industrial maintenance platform, berm,سانت بطرسبرغ30crmo سبيكة أنابيبإبداعي etc. this kind of reinforcement mesh is widely used in industry, municipal administration, electric power, coal mine and other fields, and has the strongest resistance to surface impact, especially the reinforcement mesh with a cross bar spacing of mm has a strong ability to resist lateral impact.

lR The surface of hot-dip galvanized parts is bright and beautiful.

The development of steel bar mesh is in line with the development of energy-saving economy

Straight seam welding is adopted for larger diameter welded pipe, and spiral welding is mostly adopted for large diameter welded pipe; According to the top appearance of seamless steel pipe, it is divided into annular welded pipe and special-shaped (square,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd pitch, etc.); according to different materials and main purposes, it is divided into mining anti liquid transportation welded steel pipe, hot-dip galvanized welded steel pipe for bottom pressure liquid transportation, continuous conveyor idler electric welded steel pipe, etc. it is arranged from small to large according to diameter * wall thickness according to the specification, pickling will be selected. Pickling of galvanized pipe is divided into chemical and electrolytic. How to prevent white rust of galvanized seamless steel pipe? It has a certain anti-corrosion effect on the pipeline.

wAntigua and Barbuda The finished products shall be placed away from the processing site and stacked in the designated finished product warehouse. Ventilation and other facilities shall be provided in the storage environment.

rO 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.

Silicon; it can improve the hardness of steel but the plasticity and toughness decrease. Electrical steel contains a certain amount of silicon, which can improve the soft magnetic properties
