Austenitic stainless steel is generally used for manufacturing and manufacturing chemical equipment components low-temperature equipment components in refrigeration industry, compression type, union type push type, push thread type socket welding type, union flange connection, welding type and derivative series connection mode combining welding with traditional connection. These connection modes have different application ranges according to their principles, but most of them are easy to install, firm and reliable. The sealing ring or gasket materials used for connection are mostly silicone rubber, nitrile rubber and EPDM that meet the requirements of national standards. L stainless steel pipe, s stainless steel pipe, L stainless steel pipe and other brand products are provided for a long time. The designated products are complete and the quality is guaranteed, which eliminates the need for useNsenada,According to the specification,NsenadaStainless steel groove plate, the specification of stainless steel pipe is mainly based on gb- stainless steel seamless steel pipe. The general length (indefinite length) of precision stainless steel pipe and thick wall pipe is -m for hot-rolled steel pipe and m or more for hot-rolled steel pipe. The wall thickness of cold drawn (rolled) stainless steel pipe is .-mm and the length is -m; the wall thickness of stainless steel pipe is greater than mm and the length is -m.Stainless steel pipe, which was produced and used in China at the end of the s, is a new family emerging in the field of pipe materials. It has been widely used in building water supply and direct drinking water pipelines.Soledad,The specific steps of continuous casting billet process of stainless steel pipe fittings are as follows: according to different steel grades, the vibration process of mold is matched with protective slag, which can improve the yield of %, save energy and shorten the production cycle, so as to improve the yield of molten steel.The continuous casting of stainless steel pipe fittings is generally matched with the refining furnace, which has strict requirements on the chemical composition and temperature of molten steel; In order to prevent secondary oxidation of molten steel, non oxidation protection pouring is required during continuous casting production; Strict requirements for refractory materials such as ladle, tundish, this has become a necessary means to improve product quality.

The main way to prevent stress corrosion of austenitic stainless steel is to add SI ~ % and keep the content of N below .% from smelting. In addition, the content of impurities such as P, Sb, Bi and as should be reduced as much as possible. In addition, A-F dual phase steel can be selected, which does not correspond to stress corrosion in Cl - and oh - media. The initial micro crack will not continue to expand after encountering ferrite phase, and the ferrite content should be about % . Series & mdash; Heat resistant chromium alloy steel.Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection (i.e. solid core welding wire + TIG + water-soluble paper)Packaging strategy,Deformation strengthening of austenitic stainless steel stainless steel has good cold deformation performance. It can be cold drawn into very thin steel wire and cold rolled into very thin steel strip or steel pipe. After a large amount of deformation, the strength of the steel is greatly improved, especially when rolling in the subzero temperature zone. The tensile strength can reach more than MPa. This is because in addition to the cold hardening effect, there are also superimposed Deformation induced M transition.No solution treatment. The alloy elements do not dissolve into the matrix, resulting in low alloy content and poor corrosion resistance.For more than years, architects have been using stainless steel to build cost-effective buildings. Many existing buildings fully illustrate the correctness of this choice. Some are very ornamental, such as the Chrysler Building in New York City. However, the role of stainless steel is not so eye-catching, but in the aesthetics and performance of buildings For example, because stainless steel has more wear resistance and pressure resistance than other metal materials of the same thickness it is the preferred material for designers when building sidewalks in places with large population flow.

Restate the quality of stainless steel pipe, such as stainless steel pipe,Application field: launch the market plan of stainless steel pipe in the target market of new products, such as stainless steel kitchen equipment.Stainless hot plate (grade I) GB- stainless cold strip (grade I)All steel with openings at both ends and hollow sections, and with a large ratio of length to section perimeter,Nsenada310S stainless steel heating pipe, can be called steel pipe. When the ratio of length to section perimeter is small, it can be called pipe section or tubular fittings, which belong to the category of pipe products.Nsenada,When hoisting stainless steel pipes, public slings, such as hoisting belt and public collet number, shall be used. It is strictly prohibited to use steel wire rope to avoid scratching the surface; and when hoisting and placing,NsenadaStainless steel pipe machinery and equipment, it shall prevent scratching caused by impact and collision. If there are surface scratches, electric arc traces and surface purification in the process of transportation, storage and processing, it must be completely cleaned, polished with an angle grinder, and then polished Polishing with optical sheet or metallographic sandpaper. Series & mdash; Heat resistant chromium alloy steel.Indicates that the chemical composition is represented by international chemical element symbols and national symbols, and the composition content is represented by letters: for example, China and Russia use fixed digit numbers to represent steel series or numbers; For example, the United States, Japan, series, series and series; The serial number is composed of Latin letters and order, which only indicates the purpose.
