Editor's note on the causes of steel rusting: chloride ions exist widely, sweat stains, seawater, sea breeze, soil, etc. stainless steel corrodes rapidly in the presence of chloride ions, even surpassing ordinary low-carbon steel. Chloride ions form complexes with Fe in alloy elements, reducing the positive potential of Fe, and then being stripped of electrons and oxidized [].Clamping connection steps: cut off the pipe according to the required length. When breaking the pipe, it shall not be too large to prevent the pipe from being out of round.EvlerThe cold working process performance and cold forming performance are much better than that of ferritic stainless steel.In the building water supply pipe system, due to the end of the glorious history of galvanized steel pipe, various new plastic pipes and composite pipes have developed rapidly, but various pipes still have some deficiencies in varying degrees, which are far from fully meeting the needs of water supply pipe system and the national requirements for drinking water and related water quality. Therefore, relevant experts: building water supply pipes will eventually return to the era of metal pipes. According to foreign application experience, stainless steel pipe is recognized as one of the pipes with good comprehensive performance in metal pipe.Paoua,For business people,EvlerStainless steel plate, of course, it is better to spend less under feasible conditions. For goods such as stainless steel pipes, we can often see that there will be packaging film bags on them. Although they are not heavy, but why do many people clearly dislike this thing on stainless steel pipes they will also produce certain economic expenses, xincoral Xiaobian will tell you why stainless steel pipes need packaging bags.Austenitic stainless steel is generally used for manufacturing and manufacturing chemical equipment components, low-temperature equipment components in refrigeration industry, and can be used as stainless steel spring and clock spring after deformation strengthening.Welding of stainless steel pipe argon arc welding stainless steel pipe: it is required to have deep penetration, no oxide inclusion, and the heat affected zone can be as small as possible. Argon arc welding maintained by tungsten inert gas has good compliance high welding quality and good penetration function. Its commodities are widely used in chemical, nuclear and food industries.

Stainless steel pipe packing bag is nothing more than the function of protecting the surface of stainless steel pipe, so most stainless steel pipe users do not have to question this point.The method is that the heated tube blank is placed in a closed cylinder, and the perforated rod and rod move to extrude the part from the smaller die hole. This method can produce steel pipes with smaller diameter.Model & mdash; It has better temperature resistance.safety requirements ,Formula for hydraulic test pressure of stainless steel welded pipe for weight calculation fluid (gbt-): where: P - test pressure, MPa; R - stress, taking yield point of %, MPa; s - nominal wall thickness of steel pipe, mm; D - Nominal outer diameter of steel pipe, mm.Inspection: after crimping, check the crimping size with a special gauge.Ferritic stainless steel the Cr content of ferritic stainless steel is generally % ~ %, and the carbon content is less than .%. Other alloying elements are sometimes added. The metallographic structure is mainly ferrite, and there is no & alpha during heating and cooling=& amp; amp; gt;& gamma; The transformation cannot be strengthened by heat treatment. Strong oxidation resistance. At the same time, it also has good hot workability and certain cold workability. Ferritic stainless steel is mainly used to make components with high corrosion resistance and low strength requirements. It is widely used in manufacturing equipment such as production, nitrogen fertilizer and chemical pipelines.

Because stainless steel has many ideal properties required by building materials, it can be said to be unique in metals, and its development continues. In order to make stainless steel more neutral in traditional applications, existing types have been improved, and new stainless steel is being developed to meet the strict requirements of advanced architectural applications. Due to the continuous improvement of production efficiency and quality, stainless steel has become one of the cost-effective materials selected by architects. Stainless steel integrates performance,Evler1 inch stainless steel pipe, appearance and use characteristics, so stainless steel will still be one of the best building materials in the world.Marketing Department, such as thousandth of CrNi (i.e. .% C), stainless C & le; .%, such as CRNI ultra low carbon C & le; .%, it is ~ mm, and in places with deep groove, it is ~ mm. The distance from the nozzle to the working is generally no more than mm.After fine tuning the molten steel temperature in the argon blowing station, it is lifted to the ladle rotary table for continuous casting.Evler,Stainless steel grade group Series & mdash; Chromium nickel manganese austenitic stainless steel series & mdash; Chromium nickel austenitic stainless steel model & mdash; Good ductility, used for molding products. It can also be machined to harden rapidly. Good weldability. The wear resistance and fatigue strength are better than those of stainless steel.Austenitic stainless steel. It contains more than % chromium, about % nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good comprehensive performance and resistance to corrosion of various media.At low temperature, ferritic stainless steel pipe has low-temperature brittleness like carbon steel, but austenitic steel does not. Therefore, ferritic or martensitic stainless steel produces low-temperature brittleness, while austenitic stainless steel or nickel base alloy does not show low-temperature brittleness. Sus (Cr) and SUS (cr) of ferritic stainless steel pipe It shows that the impact value decreases sharply at low temperature. Therefore,EvlerWelding method of stainless steel pipe, it is necessary to pay special attention when using at low temperature. As a way to improve the impact toughness of ferritic series stainless steel, high purification process can be considered. With the help of C and N level, the embrittlement temperature is in the range of - ℃ to - ℃
