you should first see whether its material is superior. Stainless steel is a material with strong corrosion resistance and high sanitation and cleanliness. Not only the outer wall is very beautiful, but also very smooth. There will be obvious differences in material first in terms of incision and whether the stainless steel pipe water supply pipe is good or bad.

%).It means: 100 times of Dr + iron loss value (iron loss value per unit weight when 50Hz repeated magnetization and sinusoidal magnetic induction intensity is 5T) + 100 times of thickness value. For example, dr510-50 indicates that the iron loss value is hot-rolled silicon steel plate with thickness of 0.5mm. The grade of hot rolled silicon steel sheet for household appliances is expressed by JDR + iron loss value + thickness value, such as jdr540-50.

.Chloride ions exist in the service environment. Chloride ions exist widely, such as salt,316 stainless steel square tube, sweat, sea water, sea breeze, soil, floating rust of iron foam and so on. Stainless steel corrodes rapidly in the presence of chloride ions, even more than ordinary low carbon steel. Therefore, there are requirements for the service environment of stainless steel, and it is necessary to remove dust frequently and keep it clean and dry. (in this way, we can give him a & ldquo; improper use & rdquo;) there is an example in the United States: an enterprise uses an oak container to contain a solution containing chloride ions. The container has been used for nearly 100 years. The ninetieth generation of the last century plans to replace it. Because the oak material is not modern enough, the container leaks due to corrosion 16 days after it is replaced with stainless steel.

.Clamping operation the jaw of the caliper must be placed perpendicular to the axis of the pipe and pipe fitting, and the convex ring of the pipe fitting needs to be put into the groove of the jaw for clamping. In order to prevent operation, the operator can only stand on the axis of the pipe, not on the left and right sides of the tong head.

The effect of different stabilizers on the stability of ferritic stainless steel during pickling in base solution was studied by means of weight loss curve and scanning electron microscope. The results show that under the experimental conditions, both complex stabilizer HF and adsorption complex stabilizer 5-sulfosalicylic acid can completely remove the oxide layer on the surface of stainless steel The effect of adsorbing complex stabilizer 5-sulfosalicylic acid is obviously better than that of complex stabilizer HF in the stability effect and the flatness of the research results on the properties and microstructure of stainless steel surface s stainless steel pipe after pickling. The deformation behavior at high temperature at 100 ℃ and strain rate of 0.01 ~ 5 s-1. The rheological stress curve is drawn according to the compression experimental data; based on Arrhenius relationship and considering the strain Factor, an improved constitutive equation coupled with strain factor is established; combined with optical microscope (OM) The characteristics of microstructure during material deformation are observed; the dynamic recrystallization critical strain of L stainless steel is determined according to the work hardening rate flow stress curve, and the dynamic recrystallization volume fraction model is established based on the s stainless steel pipe equation. The results show that in the process of thermal deformation of s stainless steel pipe, the flow stress corresponding to lower temperature and faster strain rate is also large; the coupling of stress variable factors The correlation coefficient between the rheological stress of the constitutive model s stainless steel tube and the experimental value is 0.986 88, and its dynamic recrystallization volume fraction and strain change in S shape. The value obtained by the model is consistent with the experimental data The volume fraction of dynamic recrystallization of s stainless steel tube during hot working can be well. Dense palladium membrane was prepared on porous stainless steel substrate with pore size of 5 & mu; m by electroplating and the combination of the two. The palladium membrane on the surface of porous stainless steel was characterized by seeds and XRD. The results show that the pretreatment is completed with 0.1 GL PdCl2 solution A pure palladium film can be prepared by electroless plating of porous stainless steel and electroplating with palladium ammonia solution with palladium content of 17 GL, the nickel content of some models of austenitic stainless steel must be slightly higher than that shown in the table; optional High TA content is 0.10%; high content is 0.75%; high content is the basic characteristics of stainless steel, with high temperature strength and high temperature plasticity, good structural stability, uniform chemical composition, good processing performance and welding performance, high dimensional accuracy and surface quality. 5 causes of rust when brown spots appear on the surface of stainless steel They were greatly surprised: & rdquo; stainless steel will not rust. Rust is not stainless steel. There may be something wrong with the steel quality. & rdquo; in fact, this is a one-sided wrong view of the lack of understanding of stainless steel. Stainless steel will also rust under certain conditions

  409— Cheap model (British and American) usually used as automobile exhaust pipe, is ferritic stainless steel (chromium steel).

Section shape stainless steel pipe can be divided into round pipe and special-shaped pipe according to the section shape. Special shaped tubes include rectangular tubes, rhombic tubes, elliptical tubes, hexagonal tubes, octagonal tubes and various cross-section asymmetric tubes. Special shaped pipe is widely used in various structural parts, tools and mechanical parts. Compared with circular pipe, special-shaped pipe generally has large moment of inertia and section modulus, and has large bending and torsion resistance, which can greatly reduce the structural weight and save steel.

The surface quality, appearance and dimensional accuracy of cold rolled steel strip are better than those of hot rolled plate.

Industry management.There are about 45 types of hot rolled (hot) stainless steel pipes with a diameter of 54-480mm and 36 types with a wall thickness of 5-45mm. There are 65 types of cold drawn (rolled) stainless steel pipes with a diameter of 6-200mm and 39 types with a wall thickness of 0.5-21mm.

According to the production mode, stainless steel pipe is mainly divided into seamless pipe and welded pipe. Seamless steel pipe can be divided into hot-rolled pipe, cold-rolled pipe, cold drawn pipe and pipe. Cold drawing and cold rolling are the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe.

The inventory of stainless steel pipes may be an important factor in market conditions. This is because at this stage, steel inventory has become an important index to investigate and judge the situation of stainless steel pipeline shopping malls, and has become a wind vane to judge the future market trend. What was the stock of stainless steel tubes at that time? It directly affects the air of shopping malls, and then distributes the business behavior of participants in shopping malls
