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, the mechanical, 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.Ostankako, Pipe installation: 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,OstankakoHow much is the galvanized pipe, multi specifications and high precision. Therefore, it is widely usedPort Macquarie, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.→ the two surfaces of the flange are parallel to each other making it easy to connect, process and install.What are the requirements for alloy pipe construction accessories


Ostankako30CrMo alloy pipeWhat problems are encountered in use



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,OstankakoWhat is the outer diameter of welded pipe DN50, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane,OstankakoHow much is DN25 galvanized pipe per ton, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures. Product description of galvanized pipeThe import and export order of I-beam is generally based on the specifications required in use after determining the corresponding carbon structure steel (or low alloy steel) steel grade. Except for the specification number, I-beam has no specific composition and performance series.superior quality, Remove defective pipes within the allowable length.I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:What should we pay attention to in the production of alloy pipe

I-beam is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Baotou Iron and steel, Shangang, huangte, Maanshan Iron and steel, Xuanhua Iron and steel Japan iron and steel,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, the mechanical, physical and chemical properties of aluminum, copper, magnesium, titanium and their alloys can be changed by heat treatment to obtain different service properties.Classification by production methodPlan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %, the interval is min.Ostankako,Heating surface pipes, economizers, superheaters, reheaters, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)The side length of I-beam is small and the height is large, so it can only bear the force in one direction.Difference and application description between H-beam and I-beam
