Under deformed conditions, welding of porosity defects is extremely difficult.Through the compression attempts of cylindrical specimens, deepen the study of the reformation and development of the porosity defects of the metal materials under the complex stress and strain conditions, and determine the elimination criterion of the porosity defects under the complex stress and strain conditions;

Rolling of high-pressure alloy pipes, sizing and reduction of steel pipes, cooling and finishing of steel pipes, or it can be said that the heating and perforation of steel billets, hot-pickling and pickling, cold-drawn carbon burning heads, spray labeling and dismantling of waste products, a seamless steel pipe The manufacturing method is characterized by: installing a rolling stand with multiple rolls and continuously deploying multiple mandrel-type seamless pipe rolling mills for different rolling targets. After the rolling of the seam steel pipe is stopped, the wall thickness of the rolled steel pipe circumference target is being measured at multiple points. According to the measurement of Liaoning, at least the thickness of the final rolling stand of the mandrel-type seamless pipe rolling mill is separately controlled. The two ends of each axis of the roll are positioned to make the uneven wall thickness reach a small.1625mm reported at 25,802,600 yuan.

Technical standards, including the development of new nickel-based alloy tubes for petroleum and power industries.The new standard defines the strength and corrosion resistance of the alloy used, outlines its chemical composition and heat treatment parameters, and lists the mechanical functions.As tungsten iron nickel 15CrMoG alloy tube tungsten carbide rods


General alloy pipes>alloy pipes>alloy pipes>high-pressure alloy pipes are referred to as seamless steel pipes. They are made of ordinary carbon steel, high-quality carbon steel, ordinary low-alloy steel and alloy structural steel, and are used to make liquid pipelines or make For structure and parts.High-pressure pipes are supplied according to outer diameter and wall thickness. There are multiple wall thicknesses under the same outer diameter, and the pressure range of high-pressure pipes is larger..The length of steel pipe is 3-12 for hot rolled pipe.5m, cold drawn (rolled) tube is 1.5-9m.This article uses thermal simulation technology, mechanical performance testing methods and microscopic analysis methods.The X100 pipeline steel's phase transformation law, strength and toughness characteristics and the change law of the structure of the X100 pipeline steel in the bending pipe manufacturing process have been systematically studied.

In the plasma arc powder surfacing process of nickel alloy, the longitudinal inverter exchange square wave magnetic field is introduced, and the stirring effect of the magnetic field is manipulated to improve the structure function of the surfacing layer..Electromagnetic induction welding technology is a new welding technology that has been perfected in recent years, and its application is becoming more and more common..The external magnetic field generally adopts the longitudinal magnetic field parallel to the arc axis.The longitudinal magnetic field promotes the rotation of the arc, changes the radial dispersion of the arc column plasma flow and current density, and affects the heating and melting of the base material and the formation of the weld..The theory confessed that the manipulation of the external magnetic field has a significant effect on the transition of the molten droplet during welding, the activity of the molten pool metal, the crystal nucleation and crystal growth of the molten pool, etc., so that the primary crystal structure of the surfacing layer is refined and the chemical Uniformity, improve the plasticity and toughness of the surfacing layer, reduce the sensitivity of crystal cracks and pores, thereby improving the function of the surfacing layer, and comprehensively improving the amount of the surfacing layer.During the test, the influence of magnetic field current and frequency of magnetic field on the hardness, wear resistance and microstructure of the surfacing layer was systematically studied, and it was emphasized that under the same welding standard, the application of different magnetic field current and frequency of different magnetic field has a great effect on surfacing welding. Comparison of layer function.The test results are as follows: 1 As long as the surfacing layer structure can be refined under the appropriate magnetic field current and magnetic field frequency..This stopped systematic theoretical research and analysis.2 Through the hardness test, wear resistance test and metallographic test, it is proved that the magnetic field can influence the primary and secondary crystalline structure, and the magnetic field current and the frequency of the magnetic field in the electromagnetic stirring process influence the nucleation rate and structure refinement..


The alloy tube has already appeared in Chen's life, but few people actually understand it. Just by its name, many people must know who rarely uses it..Then take over, the editor will introduce some application methods such as Zhang's pair of alloy tubes.Galvanized pipe.

The alloy tube (alloy tube) is a seamless steel tube with a separate structure and a high heat-resistant alloy tube..Its industrial consumption standard is different from the main alloy tube. The annealing alloy tempering of the tube changes the function of its machinery and equipment..Realize the required process conditions.Variable ratio The higher the value of uniform performance of seamless steel pipe, the more chemical composition containing Cr, high temperature, low temperature, corrosion resistant alloy pipe.Carbon seamless pipes do not include the alloy composition or alloy composition, and are more commonly used in the petroleum, chemical, electric power, boiler, military and other industries because of the many changes in the machine and equipment functions of the alloy pipe. Adjustment.Trimming process to trim or split them into individual 12cr5moi alloy tubes.

The alloy tube of 12Cr1MoV is based on a kind of high-carbon structural steel, adding one or several suitable alloying elements to improve the performance, toughness and hardenability of its machinery and equipment. The alloy tube made of 12Cr1MoV is generally subject to heat Disposal, through the use of external refining or chemical disposal before manufacturing the part.

15CrMoG alloy pipe specification: 8-12401-200mm, first used in low pressure boiler (work pressure is not higher than 5.88Mpa, the operating temperature below 450) heating the outer tube; a high-pressure boiler from the petrochemical industry (work done for heating, usually the above pressure is 9.8Mpa external tube, at 450?Work at a temperature between 650), economizer, superheater, reheater, pipe, etc..Large investors conform to the market, and retail investors are unwilling to lower prices. When the choice is at hand, the Shanghai construction steel market has not taken a firm direction for the time being.
