a. In the forming process, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size, specification and model of diameter and wall thickness, especially in the production and manufacturing of steel structure design grade thick wall pipe, especially medium diameter small thick wall pipe, and can meet a large number of customer regulations on the specification and model of alloy pipe.Alloy pipes can be used for heating (cooling) projects.Big goat,Pipelines of various specifications and models are complete.Defects of alloy pipe and solutions:Taraclia,I-beam has the dual properties of high hardness and toughness materials. Compared with other engineering wear-resistant materials in China, such as various alloy steel plates, cast wear-resistant plates, cast stones, rubber, polyurethane, etc., it has irreplaceable comprehensive excellent properties.Some applications of I-beam: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.

When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical 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. As long as the pipe material is high-strength alloy steel, including alloy steel pipes with temperature resistance, pressure resistance, wear resistance and low temperature resistance, the welding process shall be focused on preventing the tendency of martensite structure and cracks due to welding high-temperature operation. The general process requirements are that the welding rod shall be selected and baked as required and sent to the welder for use. The oil and water shall be removed before welding on both sides of the weld Rust and sundries shall be removed and cleaned. The welding line energy shall be as small as possible to minimize the swing during the welding process. The arrangement of the last weld shall have annealing effect on the heat affected zone as far as possible. Slow cooling after welding, cover with asbestos cloth, etc.It is widely used in various fields of national economic construction, such as buildings, bridges, power stations, oil drilling platforms, vehicles, highways, subways, steel structure plants and large warehousesmanagement,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, it is divided into wide light I-beam and wide flange I-beam. According to the height ratio of flange to web, medium and narrow flange I-beams. The specifications of the first two are -, that is the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Alloy tube is widely used in our daily life which provides us with great assistance. So what industries are alloy tubes applied to? Let&#;s follow the steps of all manufacturers and have a look together:

The specification of I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is cm. The types of I-beam include hot-rolled ordinary I-beam Light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~ mm, expressed as No. ~ No., and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system, cross rolling pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.Test method,Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %First, the wall thickness of high-quality and smooth steel is particularly thick. Because the thicker the wall thickness of the product 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, the process of smooth steel also determines its limitations. Generally,Big goatSeamless pipe real-time price, smooth steel has low precision, 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,Big goatHow much is the price of I-beam, 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.I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRCBig goat,Introduction to product knowledge of alloy pipe: Hot push hole diameter. More sensitive applications and facilities of such methods require simplicity, 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, and can not exceed the working capacity of thick wall pipes of machinery and equipment.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,Big goatAlloy pipe GH3030, Xuanhua Iron and steel, Japan iron and steel, etc.
