I-beamGreatly reduce the environmental pollution caused by abrasion, damage and blanking,hairQuotation for spiral welded pipe,Thanks to a zinc tube, stand in the formation and development of painful microorganisms. Remove defective pipes within the allowable length.Beirut International Airport,It is often asked that the shape of I-beam is similar to that of H-beam. What is the difference between them? Many people can&#;t explain it in detail. Here is a detailed answer for you: many people think that I-beam is a domestic name and H-beam is a foreign name. In fact this cognition is wrong. H-beam and I-beam are different in shape!→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.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, francium and other components. The alloy carbide formed has strong stability at high temperature.

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, corrosion resistance and durability. It is a kind of stronger protection.What is the of defect detection of seamless pipe? Magnetic particle testing or penetrant testing of seamless pipes can effectively find surface defects such as cracks folds, hair lines double skin, pinholes and so on. Because of its high detection sensitivity, magnetic particle detection method should be preferred for ferromagnetic materials. For non ferromagnetic materials, such as stainless steel seamless pipe, penetrant testing method is adopted. 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.Price, 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.Alloy tube is widely used in our daily life, which provides us with great assistance.

The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned,hairQ345B cold drawn seamless pipe, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film, which determines that the color of the surface layer has no change before and after passivation treatment, and the reproducibility of the solution is good.Professional is king,Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.The fourth is the welding process method to ensure the strict implementation of the special operation method of galvanized pipe. The welding process includes pre welding groove inspection, control of welding process parameters and operation methods, post welding appearance quality inspection, and post welding nondestructive testing if necessary. Control the welding level and the amount of welding materials at each crossing.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.hair, Small longitudinal crackBecause alloy pipe is a very unique pipe fitting, we must use appropriate methods to carry out installation in the case of installation, so as to ensure the performance index of the data. Generally, when installing alloy pipes, so as to ensure that the raw materials can be fixed very well. Therefore, when we carry out use, we must ensure the quality of flanges and elbows, so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline, they must be installed together.Plan scheme : Martensitic chromium alloy pipe and chromium alloy pipe with Cr composition exceeding %, without high carbon steel and high chromium alloy pipe. The aqueous solution contains % sodium cyanide % ~ % (volume ratio), the solution temperature is ~ ℃, and the solution time is min.
