DrohedaReinforcement rapid turnover softwareDo a good job of moisture-proof maintenance in rainy weather

Hot stamping. Fix the plan product workpiece or preformed vacancy on the rotating journal, with the wheel working pressure vacancy, radial wheel. After one or several solutions, 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, specification scope, mold shell and software requirements, which are very simple, very easy to be replaced, and relatively low product cost. The processing time is not long enough, the processing capacity is not high, the total length of processing pipeline is limited and the size of machinery and equipment is generally short.a. In the forming process, the thick steel plate has uniform deformation, 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 which has incomparable advantages of other processing technologies, and can meet a large number of customer regulations on the specification and model of alloy pipe.Droheda,How are seamless tubes made?The 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.Gelsenkirchen,Plan option : Martensitic chromium alloy pipe, Hot push hole diameter. More sensitive applications and facilities of such methods require simplicity, low cost, 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.→ compared with general section steel, it has the advantages of low cost, and saves about % of the manufacturing cost of steel structure.

I-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.General welded pipe: General welded pipe is used to transport low-pressure fluid. It is made of qa, qa and QA steel. It can also be made of other mild steel that is easy to weld. Water pressure, zigzag, flattening and other tests shall be carried out for steel pipes and there are certain requirements for surface quality. Generally, the delivery length is -m,Droheda16Mn large diameter longitudinal welded pipe, and fixed length (or double length) delivery is often required. The standard of welded pipe is expressed in nominal diameter (mm or inch). The nominal diameter is different from the actual. Welded pipe can be divided into general steel pipe and thickened steel pipe according to the specified wall thickness, and steel pipe can be divided into threaded and non threaded according to the way of pipe end. Judged as failing.Marketing Department, Remove defective pipes within the allowable length.Difference and application description between H-beam and I-beamGB No. I-beam is in height, in leg width and in waist thickness.

Using alloy pipe to produce ring parts can improve the utilization rate of raw materials, simplify the production and manufacturing process, and save raw materials and production and processing construction time, such as roller bearing ring throwing Nowadays,DrohedaLarge diameter high pressure alloy pipe, seamless steel pipe has been widely used to produce hydraulic jack sleeve.Economic management,The shape of I-beam is similar to that of H-beam. What is the difference between them? Product description of galvanized pipeAccording to the theory of steel structure, the I-beam flange should be stressed, that is,As shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, generally :, which makes the outer flange thin and the inner flange thick. Therefore, the section characteristics of I-beam in the two main planes are very different, the structure of the I-beam has determined its torsional performance. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.
