Alloy pipes can be used for heating (cooling) projects.At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.Kanthal ,Galvanized steel pipe: in order to improve the corrosion resistance of steel pipe, general steel pipe (black pipe) shall be galvanized. Galvanized steel pipes are divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick and the cost of electro galvanizing is low.After isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.Solrod Strand, Frame line crackMain uses: as a finished material, flat steel can be used to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators in buildings. Flat steel is divided into two types according to its shape: plane spring flat steel and single-sided double groove spring flat steel. Hot rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery.The high-temperature passivation treatment of alloy pipe is to obtain the passivation treatment film by heating in the heat treatment equipment. Before passivation treatment, the passivation treatment film can be obtained according to the transformation temperature and time. The hue of passivation treatment film can refer to the annealing color of alloy pipe, and the main parameters of ambient temperature and time of heat treatment process can be selected.

At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.It is divided into circular welded pipe and special-shaped (square, flat etc.) welded pipe.C - section steel is reliable and stable in stress, can be accurately positioned, and is resistant to impact and vibration Moreover, it has good versatility and combination, and has a variety of C-section steel and size selection to ensure its flexibilityQuality risk,Generally, the process of pickling and passivation will be carried out for alloy pipes, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing, there is no harm to carry out hot galvanizing in the middle and later stage.Greatly reduce the environmental pollution caused by abrasion, and increase the labor cost of material cleaningDue to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main sleeves of the section is quite different, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.

Hot stamping. Fix the plan product workpiece or preformed vacancy on the rotating journal, with the wheel working pressure vacancy, radial wheel. After one or several solutions, there can also be a variety of methods for the whole process of hollow thick wall rotating body products. Products manufactured by high-precision processing method have excellent physical properties, specification scope, mold shell and software requirements, which are very simple, very easy to be replaced, and relatively low product cost. The processing time is not long enough, the processing capacity is not high,Kanthal SA213T91 alloy pipe, the total length of processing pipeline is limited, and the size of machinery and equipment is generally short.Test conclusion,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!Generally speaking, the precision of seamless pipe is relatively low, and it is prone to uneven wall thickness, low surface luminosity and high customization cost. At the same time some pits or black spots are easy to appear on the inner and outer surfaces. In addition to these, and its strength is relatively high the seamless pipe manufacturer needs to carry out off-line processing for its detection, the pressure is high, and its advantages can be reflected in the material of mechanical structure. Seamless pipe can be divided into hot extrusion, hot rolling and cold rolling stainless steel pipe according to its rolling method. In addition, different elements can also be used for classification. The inner and outer surfaces of seamless pipes shall be free from chaps, cracks, scabs, delaminations and other defects. If these defects are to be removed, it is necessary to use machining. The removed seamless pipes shall not have negative deviation after the inner diameter is followed, If other minor surface defects with negative deviation cannot be removed, it is not a qualified product. The allowable depth diameter of straight path of seamless pipe is less than or equal to mm, and its depth shall not be greater than . mm. Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time,Kanthal 15CrMo thick wall alloy pipe, and the waist is parallel to the roll axis.Kanthal ,Key technical characteristics of alloy pipe:Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materialsApplication scope of alloy pipe
