→ the two surfaces of the flange are parallel to each other,ChuanguHow much is a welded pipe meal, making it easy to connect, process and install.Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, whether it is fire water system software, water supply equipment, or pipeline, alloy steel pipe stimulates important effects.Chuangu,The use of hot dip galvanizing has expanded with the development of industry and agriculture. Therefore, hot-dip galvanized products have been widely used in industry (such as chemical equipment, petroleum processing marine exploration, metal structure, power transportation, shipbuilding,ChuanguGh4105 alloy pipe, etc.), agriculture (such as sprinkler irrigation, construction (such as water and gas transportation, wire casing, scaffold, house, etc.), bridges, transportation etc. because hot-dip galvanized productsHeating surface pipes, economizers, superheaters, reheaters, pipes for petrochemical industry, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)Chrudim,Stages needing attention in the production and manufacture of alloy tubesThe delivery length of I-beam is divided into fixed length and double length and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into -,ChuanguAll selection of Cold Drawn Welded Pipe, - and - according to different specification numbers. The length selection range of imported I-beam is generally -.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, magnesium, titanium and their alloys can be changed by heat treatment to obtain different service properties.

Methods of exerting efficiency in application of C-section steelFrom the current scope of use it is mainly widely used in glass curtain wall, power tower, communication power grid and other industries. In recent years, it has been widely used in many regions and industries, which is enough to show that the quality of galvanized pipe is very good, and it also brings a lot of convenience in the process of use, so it can be used better.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.quality index,H-shaped steel groove is deep and thick, and can withstand forces in two directions.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. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.I-beam features: the content of chromium carbon alloy is -%, and the macro hardness is - HRC

Dry processing technology: after passivation treatment, parts shall be dried with air compression or hot gas, or drying treatment or air drying can be selected.High quality and low price,Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, 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. The use of I-beam shall be selected according to the requirements of design drawings.Check whether the manufacturer&#;s qualification, business license, organization code certificate, tax registration certificate, production and operation license and other qualification materials are complete. Look at the case, investigate the supplier&#;s performance and the projects served in the past. Whether there is a self built logistics fleet or not, choosing a service provider with a self built logistics fleet can reduce the transportation cost, and more importantly, ensure the timeliness of delivery. After sales service, whether there is a sound and reliable after-sales service guarantee system, and timely solve quality problems in arrival acceptance and subsequent use. Check whether the quality assurance materials such as product quality certificate, material specification and warranty are complete. Check the appearance of the welded pipe, the surface is smooth and flat, the weld is dense, without burr, oil stain, corrosion, extrusion deformation and flat cross section. Use a micrometer to check whether the outer diameter and wall thickness of the welded pipe meet the requirements, and the standard wall thickness deviation shall not exceed % - %. NDT shall be carried out for welded pipe with flaw detector. Conduct bending tensile strength test according to the requirements, bend the welded pipe for degrees, and there is no crack at the bend.When we carry out different projects, we must use different raw materials, 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:Chuangu,Generally there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.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, Shangang, huangte, Maanshan Iron and steel, Xuanhua Iron and steel, Japan iron and steel, etc.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.
