Difference exceeds the difference so r410a refrigerant recharge kit

72%, accounting for 80. Because eating strip edge, always partial lack of meat, steel strip in the welding easy to crack, crack and affect the stability of the weld quality. Requirements section of the same thickness difference does not exceed the predetermined value of the steel pipe, which requires a high degree of uniform wall thickness of the pipe, fluctuations in the thickness of the strip, the same volume will be transferred to the allowable value of the wall thickness of the finished steel strip thickness difference exceeds the difference so r410a refrigerant recharge kit that a large number of steel tube wall thickness exceeds the allowable deviation and scrap judgment. When the tensile strength is less than 30 0MPa, the strip material in the molding process due to the soft, easily wrinkled surface. Eating strip edge (ie, the strip edges jagged uneven phenomenon), generally appear in the tape slitting, slitting machine causes the disc blade blunt or sharp result. Through the company Φ76mm high frequency welded steel pipe(erw steel pipe) unit for a month unqualified statistics that affect steel product quality in the production process elements include raw materials, welding process, the roll adjustment, roll material, equipment failure, the production environment and other reasons seven aspects.99%, it is a relatively minor part.44%, accounting for 24. Visible, the mechanical properties greatly influence the quality of the steel pipe, steel pipe strength of the material should effectively control the quality.01% the sum of the three, is the main link.Frequency welded pipe production process, how to ensure the quality of products meet the technical standards and the needs of customers, we have to factor in steel production process affect product quality analysis. fluctuations affect not only the thickness of the finished steel thickness accuracy, and because the strip of varying thickness, the steel pipe during welding, extrusion pressure and welding temperature instability, resulting in a unstable weld quality when welding steel. Therefore, fluctuations in the strip width, not only affects the accuracy of the outer diameter of the steel pipe, but also seriously affect the quality of the surface of the steel pipe.85 percent the welding process, the roll adjustment accounted for 22. When the tensile strength of steel exceeds 635 MPa, elongation of less than 10% of the strip during welding seam prone to crack. Wherein the raw materials accounted for 32. The four elements of roll materials, equipment failures, and other production environment and other reasons, the impact on the quality of steel products accounted for 19. Therefore, before steel welding, to check each roll strip surface quality and geometry of the strip does not meet quality standards, not production, so as to avoid unnecessary losses. In the steel molding process, camber and wavy cause deviation or flip the strip, easy to produce steel pipe weld lap welding, affecting the quality of steel pipe. Thus, in the steel production process, to deal with raw materials, welding technology and roll adjustment control to focus on three aspects. Further, since the interior of a steel material defects exist sandwich, impurities, such as trachoma, it is also an important factor affecting the quality of steel. ) The strip surface defects on steel strip surface quality defects are common Camber, wavy edge slitting eating several, camber and wavy generally appear in the cold-rolled strip rolling process, by reduction caused by improper control..Effect of Geometry on the quality of steel strip when the strip width is less than the tolerance, the pressing force is reduced when the welded steel pipe, steel pipe weld welding so weak, cracks or open tube; when the width of the strip greater than tolerance, the pressing force is increased when the welded steel pipe, steel pipe welds appear beak, lap welding and other welding defects or burrs.Strip yield point and high tensile strength, it will cause difficulties in forming the strip, particularly when thick wall, resilient materials, large, large deformation stress in the presence of pipe welding, weld cracks easily


R134a refrigerant price high strength oil well pipes

The higher the strength of steel, the greater the sensitivity of sulfide stress cracking, so good to sulfide stress cracking resistance of high strength steel for development. In addition, add the Mo can make in the trace H2S environment passivity oxide film stability, inhibition of hydrogen in the steel.From the perspective of corrosion resistance, corrosion resistant alloy steel can be roughly divided into system of martensite stainless steel, duplex stainless steel and austenite system high Ni alloy three kinds.Oil Wells and gas Wells steel pipes include the drill pipe for mining, well wall protection pipe inserted inside the well to prevent formation collapse and pipeline system hanged inside the wall protection tube for production.Its critical temperature and corrosion resistant alloy elements of the content of Mo and W, depending on the use environment, has developed a Mo and W content different alloy series..In oil Wells and gas Wells with plenty of H2S, can use the austenite high Ni alloy with good corrosion resistance. CO2 and H2S production fluid with together, but can form weak acid after CO2 dissolved in water, can be used as consumption due to steel corrosion reaction of the source of H + ions, so compared with the same acid aqueous solution pH, the corrosion rate of carbon steel.However, the sulfide stress cracking accident happened in the 50s in Canada, so sulfide corrosive environment sulfide stress cracking of high strength steel aroused people's concern.In oil Wells in severe corrosion environment, usually to inject steel rust preventer protection, but no matter technically, or from an economic point of view, anticorrosive agent application is very difficult, therefore developed suitable for all kinds of corrosive environment, without injecting antifushiji the corrosion resistance of alloy steel. Especially under the environment of high temperature, duplex stainless steel containing 22% ~ 25% Cr can be used.Sulfide stress cracking of low alloy steel is a kind of form of hydrogen embrittlement, the production fluid with the system of hydrogen sulfide inhibits corrosion reaction in the process of hydrogen produced by dissipation, to invade the significantly increased the amount of hydrogen in steel.Since the 60s have developed resistance to sulfide stress cracking of low alloy oil well drill pipe, and has made steady development.Based on security considerations, oil well pipe generally adopts seamless steel pipe. The CO2 corrosion environment is often referred to as low sulfur corrosion environment.The sulfide stress cracking resistance of steel is associated with the microstructure of steel.From martensite phase organization view shows the following measures is effective: adding Nb and quenching tempering heat treatment can form fine grain structure; Reduce the intergranular segregation elements such as P and Mn can prevent the grain boundary cracks; Increasing tempering temperature can reduce the internal strain, etc.In the deep well, due to the high bottom hole temperature (5000m class well, downhole temperature about 250 e), so the corrosion environment is very serious.However, because of 13 Cr steel under the temperature of more than 150e, corrosion speed will increase, and the traces of H2S environment with sulfide stress cracking sensitivity, thus developed a new type of 13 Cr steel, namely by lowering the content of C, inhibition of Cr carbide precipitation, ensuring effective amount of Cr, which can improve the application of the critical temperature in CO2 environment.As a result of the oil well and gas well mining depth deepening year by year, such r134a refrigerant price high strength oil well pipes as N80 (yield strength 551 MPa grade) and P110 (yield strength 758 MPa) are developed, these pipes have reached the American petroleum institute standards. To reduce under the environment of CO2 corrosion rate, effective solution is to add Cr, now good to under the environment of CO2 corrosion resistance and economy of 13 Cr steel (AISI420) demand increased rapidly
