Peak crack The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.Bono, When the mesh reinforcement on both sides of the beam is different the reinforcement on both sides extends into the beam, and the reinforcement anchorage length is required.Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlementSanta-Rita, Miscellaneous scabAlloy pipes can be used for heating (cooling) projects.→ the two surfaces of the flange are parallel to each other, making it easy to connect, process and install.

Alloy pipe is a kind of seamless steel pipe. Alloy pipe is divided into structural seamless pipe and high-pressure heat-resistant alloy pipe. It is mainly different from the production standard and industry of alloy pipe. Annealing and tempering of alloy pipe changes its mechanical properties. Meet the required processing conditions. Its performance is higher than that of ordinary seamless steel pipe,BonoCold drawn seamless pipe manufacturer, its utilization value is higher, the chemical composition of alloy pipe contains more Cr, and its performance of high temperature resistance, low temperature resistance and corrosion resistance. Ordinary carbon seamless tubes do not contain alloy components or have few alloy components. Alloy tubes are widely used in petroleum, aerospace, chemical industry, electric power boiler and other industries because the mechanical properties of alloy tubes change and are easy to adjust. The surface of hot-dip galvanized parts is bright and beautiful. Hot stamping. Fix the plan product workpiece or preformed vacancy on the rotating journal, with the wheel working pressure vacancy, specification scope 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, mold shell and software requirements,BonoQ345B longitudinal welded pipe factory, which are very simple, and relatively low product cost. The processing time is not long enough, the total length of processing pipeline is limited, and the size of machinery and equipment is generally short.Latest consultation,Defects of alloy pipe and solutions:Requirements of alloy tubes for low and medium pressure boilersThe working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction, so that the width is compressed to achieve the expected parameters, and the compression amount is adjustable; Straighten the width with staggered straightening wheels.

It is a potential rolled strip steel with rectangular section for general purpose. It is very common on construction sites. Its specifications are expressed in thickness and width. At present, most of the flat steel on the market are finished steel, which can be used ready-made for components, ladders, bridges and fences. Flat steel can also be used as blank for welding rigid steel and slab for laminated thin plate.Let's see,Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal, eliminate structural defects, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process, it will eventually lead to bad harm to the product quality.The smooth of steel pipe is mainly through tension reducing, which is a continuous rolling process of hollow base metal without center and tip. Under the condition of ensuring the capillary welding quality,BonoSeamless pipe manufacturer, the whole welded pipe is heated to more than ℃ by the welded pipe tension reduction process, and then rolled to finished pipes with various outer diameters and wall thicknesses by the tension reduction machine ( times in total). The fluid pipes produced by developed countries in the world have adopted the welded pipe smooth process in a large number of boiler pipes. With the development of society, Domestic hot welded pipe has gradually formed a situation to replace smooth pipe.Alloy pipes can be used for heating (cooling) projects.Bono,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 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. 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, and the waist is parallel to the roll axis.Introduction to product knowledge of alloy pipe:
