Hot hole breaking cold rolling method. This method is dominated by expansion and expands vertical sliding and skew rolling. The former one is mainly cold rolling by relatively limited mandrel mill, 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 usedWhether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.Melnick,First, the higher the economy and practicability. The thinner the wall thickness, the greater the processing cost and opportunity and the higher the resource cost. Secondly, smooth steel has low precision the process of smooth steel also determines its limitations. Generally, uneven wall thickness, low brightness inside and outside the pipe, high length cost, pockmarks in the internal appearance, and black spots are not easy to remove. Again, the inspection and shaping need to be processed offline. Therefore, it has its advantages in high pressure, high strength and mechanical structure materials. In the process of use, we will gradually find out. In fact, seamless pipe has also entered the market in recent years. With the growth of market demand, the advantages of seamless pipe have also been stimulated. But there are also many fakes and fake products on the market. Be careful when you choose.The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages.Barrelli,When we carry out different projects, we must use different raw materials,MelnickGH4169 superalloy tube,Melnick10# steel seamless pipe, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, we will apply it, so it is very popular in the field. When people carry out the construction of alloy pipe project, there are many things that must be paid special attention to. Let&#;s take you to know:I-beam, also known as universal beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.In order to make the welded pipe have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and forming process, heat treatment process is often necessary. In addition, physical and chemical properties of aluminum copper, magnesium, titanium and their alloys can be changed by heat treatment to obtain different service properties.

Alloy pipes can be used for heating (cooling) projects. Material requirementsThe 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.Highly recommended,I-beam can be divided into four types according to shape: cold-formed equal edge I-beam, cold-formed unequal edge I-beam, cold-formed inner crimping I-beam and cold-formed outer crimping I-beam.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.→ the two surfaces of the flange are parallel to each other, process and install.

Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members.High quality and low price,Greatly reduce the environmental pollution caused by abrasion, damage and blanking, and increase the labor cost of material cleaningWhen the beam width is small, the reinforcement shall be bent.The pickling agent in the pickling process contains many acidic substances, including hydrochloric acid, sodium cyanide, etc., which has strong corrosion and reduction, and the temperature of etching substances is relatively high. Therefore, the corrosion resistance of alloy pipes is specified higher.Melnick,When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size. 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.Alloy pipe is a spiral seam seamless steel pipe, which is made of hot-rolled strip steel coil, often processed by warm extrusion and welded by automatic double wire double side arc welding process. The alloy pipe sends the hot-rolled strip steel to the welded pipe unit, and the hot-rolled strip steel is extruded through multiple passes. The hot-rolled strip steel is rolled slowly to produce annular pipe material with open mouth gap. Adjust the reduction amount of the extrusion roll to control the welding gap at ~ mm and make both sides of the weld flush. Small longitudinal crack
