Remove defective pipes within the allowable length.Generally, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing, there is no harm to carry out hot galvanizing in the middle and later stage.Jerino,Wire sleeve: it is also a general carbon steel welded steel pipe. It is used in concrete and various structural power distribution projects. The commonly used nominal diameter is from -mm. The wall of wire sleeve is thin, which is mostly used after coating or galvanizing, and cold bending test is required.Generally, the process of pickling and passivation will be carried out for alloy pipes, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing, there is no harm to carry out hot galvanizing in the middle and later stage.Caria,Defects of alloy pipe and solutions:After isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment. Small longitudinal crack

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,JerinoHow much is 90 galvanized pipe, it is proved that ZYS- bearing damping and antirust oil has outstanding damping effect and good antirust lubrication performance.Galvanized pipe is a name for square pipe, that is, steel pipe with equal side length. It is made of rolled strip steel after process treatment. Steel pipe has been an essential material in building decoration. Galvanized pipe is also used more in decoration, but hot-dip galvanized steel pipe manufacturers need to know about the size of galvanized pipe and several common sizes of galvanized pipe which is helpful for your purchase!The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages.Energy costs,At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.Alloy tube is widely used in our daily life, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.agent,Due to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries.The reinforced concrete surface reinforcement method has the advantages of simple construction technology and strong adaptability, which can greatly improve the bearing capacity, flexural stiffness and ductility of the brick wall. At the same time, porous hollow brick wall and mm thick empty bucket brick wall with no cracks and shear in the original wall.The specification of pass design I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is. 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 ~, expressed as No. ~ No., and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system, cross pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.Jerino,Its heat sealing effect is remarkable. It can be directly buried immediately which can not only save resources, but also reduce consumption, not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.Passivation treatment operation of alloy pipeAlloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline whether it is fire water system software, water supply equipment, or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system, alloy steel pipe stimulates important effects.
