Frame line crackWelded 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, which will lead to uneven volume expansion and contraction and produce stress, that is, thermal stress.Tepelena,According to the shape of the product, special flour, welding or ordinary thread connection shall be used.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, that is medium and narrow flange I-beams. The specifications of the first two are -, 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.Fanipol,I-beam is widely used in buildings or other metal structures.Plan option : Martensitic chromium alloy pipe,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,TepelenaSteel pipe, especially in the production and manufacturing of steel structure design grade thick wall pipe,TepelenaGH3536 alloy 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.

→ compared with the concrete structure the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %, and reduce the structural design internal force. If the surface of the welded pipe is rusty, we can polish the appearance of the welded pipe with a wire brush to prevent rust.The pickling agent in the pickling process contains many acidic substances, including hydrochloric acid,Tepelena273 seamless pipe meter price, sodium cyanide, etc., which has strong corrosion and reduction, and the temperature of etching substances is relatively high. Therefore, the corrosion resistance of alloy pipes is specified higher.quality, The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.b. The professional two-sided arc welding processing technology can complete the electric welding at a good position, which is not easy to have the disadvantages of staggered joint, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.

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.Quality management,The wear resistance, fracture toughness, impact toughness and bending strength under different process conditions were compared, and then the heat treatment process of GCrMo was determined. Development and application of ZYS- bearing damping and antirust oil. Bearing is a new type of multial damping and antirust oil. It takes refined mineral oil as the base oil and is equipped with various additives such as antirust and antifriction. Through comparison test matching test with lubricating grease and user test, it is proved that ZYS- bearing damping and antirust oil has outstanding damping effect and good antirust lubrication performance.Characteristics and application of galvanized pipeI-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.Tepelena,Plan option : Martensitic chromium alloy pipe,Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.Determined by the shape, the section modulus, moment of inertia and corresponding strength of I-beam are obviously better than those of ordinary I-beam with the same single weight. When used in metal structures with different requirements, it shows its superior performance in bearing bending moment, pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.
