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 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.Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline,Hoger15CrMoG large diameter alloy pipe, whether it is fire water system software, water supply equipment, or pipeline, alloy steel pipe stimulates important effects.Hoger,The first is people. Human factors are the control focus of welding. Therefore, before welding, welders with skilled technology and welder certificate shall be selected for necessary technical training and disclosure. It shall not be replaced at will to ensure the relative stability of the welders welding the pipeline. Frame line crackGagarin,The utility model has the advantages that the axial force of the roll is small,HogerHot dip galvanized welded pipe factory, the axial movement is small, the working inclined plane is not required, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body.→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.H-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel, profiled steel plate, etc.). Due to the reasonable section shape, they can make the steel give more play to its performance and improve the cutting capacity. Different from ordinary I-type, the flange of H-section steel is widened, and the inner and outer surfaces are usually parallel, so it is convenient to connect with other components with high-strength bolts. Its size composition is reasonable, series and models are complete, which is convenient for setting

The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge. Spiral welded steel pipe (sy- for pile is made of hot-rolled steel strip coil as pipe blank, often warm spiral forming, double-sided submerged arc welding or high-frequency welding. It is used for foundation pile of civil building structure, wharf, bridge, etc. 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.Latest consultation,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. 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 pipes can be used for heating (cooling) projects.I-beam is mainly used in building structure, curtain wall engineering, economizers, superheaters, reheaters, pipes for petrochemical industry, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)Inspection itemsThe system is mainly composed of control box, finishing roller, pre leveling unit, finishing unit and straightening unit.Galvanized pipe cleaning, east-west derusting, pickling and shot blastingThe side length of I-beam is small and the height is large, so it can only bear the force in one direction.Hoger,At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.After isothermal quenching treatment
