9Buttress shall be set at the turning of T-interface pipeline in vertical or horizontal direction. The size of buttress shall be determined through calculation according to pipe diameter， corner， working pressure and other factors.
s. This tightly adhered chromium rich oxide protects the surface from further oxidation. This oxide layer is very thin. Through it， you can see the natural luster of the steel surface， which makes the stainless steel have a unique surface. Moreover， if the surface layer is damaged the exposed steel surface will react with the atmosphere to repair itself，Stainless steel coil re form this passive film and continue to play a protective role.

Sl — Cheap model (British and American)， usually used as automobile exhaust pipe， is ferritic stainless steel (chromium steel).
Cutting tool level & rdquo; Martensitic steel， an early stainless steel similar to Brinell high chromium steel. It is also used for surgical tools， which can be made very bright.
Let PS be the external force at the yield point s and fo be the cross-sectional area of the sample， then the yield point & sigma; S = PS / fo (MPA)， MPa is called MPa， equal to n (Newton) / mm (MPA = pa， PA: Pascal = n / M
g. Raw material problem of stainless steel pipe. If the hardness is too low， it is not easy to polish (BQ is not good). If the hardness is too low，Stainless steel coil orange peel is easy to appear on the surface during deep drawing， which affects BQ performance. BQ with high hardness is relatively good.
EIn order to prevent water from serious pollution during storage and transportation，Price list of 30 stainless steel pipeWhat are the main advantages of the water industry now generally uses stainless steel pipes to store and transport water. Because stainless steel pipes have anti rust， high temperature and high pressure resistance and good sanitary performance， stainless steel pipes are slowly used in the industrial field!.
CWhich one is betterThere are ba face， b face， (white skin)， D face， (frosted)， K face and other surfaces with good quality and brightness.
vMDo a good job of preliminary data research. In the highly competitive market，tisco stainless steel sheet,taigang stainless steel sheet,stainless steel sheet,stainless steel coil,stainless steel strip,stainless steel tube-TISCO Stainless Steel Co.,Ltd stainless steel pipe dealers should go deep into the hinterland. It is essential and crucial to do a good job of pre market data research; Only by fully grasping consumer demand trends， habits and other data can we have more confidence to compete for market share. Therefore， the editor of stainless steel pipe believes that in-depth data mining and comprehensive market analysis are powerful for stainless steel control manufacturers in this movement.
SPHC—& mdash; In the first place s is the abbreviation of steel， P is the abbreviation of plate， h is the abbreviation of hot heat， and C is the abbreviation of commercial. It generally represents hot-rolled steel plate and strip.
At low temperature， the company specializes in selling stainless steel plates， coils， belts and tubes with quality assurance. The company specializes in selling， timely supply and high cost performance. It has become the first choice brand for many wire products. Welcome to buy! Ferritic stainless steel tubes have low temperature brittleness like carbon steel， while austenitic steel does not. Therefore， ferritic or martensitic stainless steel produces low temperature brittleness Temperature embrittlement， but austenitic stainless steel or nickel base alloy does not show low temperature embrittlement. Sus (Cr)， SUS of ferritic stainless steel pipe (cr) and others show a sharp drop in impact value at low temperature. Therefore， when the embrittlement temperature is improved in the range of - ℃ to - ℃， it is possible to use it in freezing related projects SUSL has applied suslx (cr Ti， Nb LC) and susl (cr Mo Ti Nb LC) to the shell of refrigeration appliances. Ferritic stainless steel has body centered cubic structure. When the material properties become weak， sharp cracks will expand rapidly and cause brittle failure. Austenitic series stainless steel will not produce brittle failure because it is face centered cubic structure. Arctech has invested in stainless steel (cr-ni-lc) and SUSL (cr-ni-mo-lc) show that they still have superior impact characteristics at low temperature. However， pay attention to the precipitation of ferrite or martensite due to processing， and the tendency of embrittlement caused by carbide or & sigma; equal heterogeneous precipitation due to sensitization.
consumptioneNo matter under dynamic load or static load， it has higher energy absorption capacity than austenitic stainless steel， which has obvious advantages and practical application value for structural parts to deal with sudden accidents such as collision and explosion. Compared with austenitic stainless steel， duplex stainless steel has the following disadvantages: its universality and versatility are not as good as austenitic stainless steel. For example， its service temperature must be below ℃.
NFormula 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.
The stainless steel pipe installed on the pipeline support can be corroded by ppm chloride ion and ppm residual chlorine in an aerobic environment. For carbon steel structural supports， the pipeline shall be insulated to prevent corrosion due to potential difference and the external insulation cotton shall be wrapped for anti-corrosion treatment. Remember， never use glue and other materials that contain chloride ions， halogens and other corrosive effects on stainless steel pipes.
eThe 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 -sulfosalicylic acid can completely remove the oxide layer on the surface of stainless steel The effect of adsorbing complex stabilizer -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 ℃ and strain rate of . ~ s-. The rheological stress curve is drawn according to the compression experimental data; based on Arrhenius relationship and considering the strain Factor， 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 pipe and the experimental value is . ， and the average relative error is only %. The model can better predict the deformation resistance of L stainless steel in the process of thermal deformation
zIExtrusion method means that the heated tube blank is placed in a closed extrusion cylinder， and the perforated rod moves together with the extrusion rod to extrude the extrusion part from the smaller die hole. This method can produce steel pipes with smaller diameter.
There are about types of hot rolled (hot extruded) stainless steel pipes with a diameter of -mm and types with a wall thickness of -mm. There are types of cold drawn (rolled) stainless steel pipes with a diameter of -mm and types with a wall thickness of .-mm.
