Welded steel pipes need to be processed through various processes before application. The heat treatment of welded steel pipes is a very important link in the processing of welded steel pipes. Hot working is a metal hot working process in which metal materials are heated, insulated and cooled in a certain medium, due to the inconsistency of cooling speed and time between the surface and the core, the temperature difference will be formed, which will lead to uneven volume expansion and contraction and produce stress, that is, thermal stress.The system is mainly composed of control box, finishing roller, pre leveling unit, finishing unit and straightening unit.Wolfsburg,Next, let&#;s introduce the operation steps of roll adjustment during roll change. First of all, we must replace the specification and model of the welded pipe manufacturer. Generally, replace the complete set of rolls. The adjustment process of the rolls is as follows: first, draw an axis from the channel of the generator set to the import and export with stainless steel wire for adjustment so that the holes of each frame plate are on the same axis, and the bottom line of forming ethics meets the technical standards.Alloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.Owando,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. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge. Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time, and the waist has an included angle with the horizontal axis.

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. Because the zinc coating has excellent ductility, it can be formed by cold stamping, rolling, bending and so on without damaging the coating.All the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.Safety and health,I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.After determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment, put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply, If the current flows from the positive stage to the negative stage, a layer of zinc is deposited in the pipe.

When we carry out different projects, we must use different raw materials,Wolfsburg12cr5moi alloy pipe, 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,WolfsburgHow much is 1 meter of 50 welded pipe, 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:Discount,GB No. I-beam is in height, in leg width and in waist thickness.It is also divided into general welded pipe galvanized welded pipe,WolfsburgHow much is the price of welded pipe, oxygen blowing welded pipe, wire sleeve, metric welded pipe, idler pipe, automobile pipe, transformer pipe, electric welding thin-wall pipe, electric welding special-shaped pipe,Stages needing attention in the production and manufacture of alloy tubes Peak crackBecause all parts of I-beam are arranged at right angles, simple construction cost saving and light structural weight in all directions, and has been widely used. The inner and outer sides of the flange of the I-beam are parallel or close to parallel, and the end of the flange is at a right angle, so it is named parallel flange I-beam. The web thickness of I-beam is smaller than that of ordinary I-beam with the same height of web, and the flange width is larger than that of ordinary I-beam with the same height of web, so it is also named wide edge I-beam.
