4Stainless steel pipe national standard thickness in the stainless steel pipe industry， the steel that meets the national standard is generally called & ldquo; National Standard & rdquo; Inferior steel that does not meet national standards is called & ldquo; Winning the bid& ldquo; Non standard & rdquo; In practical application， the quality of national standard and non-standard is similar， mainly due to the difference in thickness. A thickness of national standard is actually mm， but a thickness of non-standard is actually only .mm or other thickness less than mm. Non-standard is basically equivalent to winning the bid. Standard index size (mm) label number standard implementation standard gbt- non-standard specific thickness ratio outer diameter steel pipes are produced according to the standard. non-standard belongs to customized difference. Wood office says ha ha customized on demand. thickness area: the difference between standard， thickened，Stainless steel strip stainless steel American Standard and national standard mainly lies in C content and P content; The C content and P content of Chinese standards are lower than those of American Standard ASTM A@_@ The two important elements of material are chromium and nickel，446 stainless steel platePrinciple of heating temperature large plants and large plants of national standard and small plants of American Standard @_ @ The national standard contains more than chromium and the American Standard contains more than chromium@_@ Stainless steel pipe is an American Standard， not in the national standard. The corresponding national standard is crni.
oThe slab solidified on the surface continues to be rapidly cooled through the secondary cooling section until the core becomes solid， and the whole continuous casting process of stainless steel pipe fittings is completed.
Among the steel products exported by China， steel pipe has always been the focus of foreign anti-dumping and countervailing investigations. The Russian Ministry of industry and trade announced that it would launch an anti-dumping investigation on Chinas cold-rolled stainless steel seamless steel pipes exported to the Russian Belarus Kazakhstan customs union. Before that， the Brazilian foreign trade chamber also said that it would impose an anti-dumping tariff of US $ per ton (about RMB yuan) on Chinas steel pipe products， which is valid for five years.
WBesanson UniversityRemarks: to ensure the nickel content of stainless steel strip and the mechanical properties of stainless steel strip， material certificate (Baogang material)， Japan Nippon Steel Material Certificate (Nippon Steel material)， SGS report，Stainless steel strip etc. can be provided.
XoMechanical properties when the steel or sample is stretched， when the stress exceeds the limit， even if the stress is no longer increased， the steel or sample continues to have obvious plastic deformation， which is called yield， and the small stress value when the yield phenomenon occurs is the yield point.
Buttress 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.
after deep drawing， which will affect the BQ attribute.
eModel & mdash; Cheap model (British and American)， usually used as automobile exhaust pipe，Stainless steel strip is ferritic stainless steel (chromium steel).
MThe inner and outer surfaces of steel pipes shall be free of cracks， folds，446 stainless steel platePrinciple of heating temperature crazing， cracks， rolling folds， delaminations and scabs. These defects shall be completely removed (except for pipes for machining). After removal， the wall thickness and outer diameter shall not exceed the negative deviation. Other minor surface defects that do not exceed the allowable negative deviation may not be removed.

It is generally suitable for the welding of thin plates below mm， the ordinary steel pipe will rust after being used for a period of time because the family kitchen and are in a humid environment for a long time the service life is not long， and it will affect the safety of family drinking water! Therefore， the use of stainless steel pipe here can ensure long-term non rusting， and the corrosion resistance and tensile resistance of stainless steel pipe itself. Professional sales of stainless steel plate， stainless steel coil， stainless steel belt， stainless steel pipe， safety， environmental protection economy! The products are exported to foreign countries and are deeply trusted， which makes the stainless steel pipe more and more popular in the field of home decoration!
assetseSelection process of stainless steel pipe water supply pipe.
JAustenitic stainless steel has good resistance to uniform corrosion， intergranular corrosion also occurs in the heat affected zone of the weldment. This is due to the precipitation of Cr rich CrC on the grain boundary. The chromium poor area is formed in the surrounding matrix the greater the tendency of intergranular corrosion. In addition， which is caused by corrosion of the primary cell. This intergranular corrosion phenomenon also exists in the ferritic stainless steel mentioned above.
Doing well in marketing strategy innovation is a very key factor for every manufacturer joining stainless steel pipe to realize the marketing effect of market competition; However， due to the different characteristics of each market， stainless steel pipe manufacturers need to make different marketing strategy adjustments; As the saying goes， catching mice is a good cat& rdquo; The companys professional sales projects include: stainless steel plate， stainless steel coil， stainless steel belt， stainless steel pipe and other related businesses. Merchants who hope to have this business please contact. This is also true in the marketing strategy. Therefore， manufacturers of stainless steel pipes need to make marketing innovation at any time to match the changing market conditions.
a after deep drawing， small black spots and RI high imitation dging will also appear on the surface of the area with large deformation， which will affect the BQ attribute.
hWCold rolled steel strip shall be delivered in the state of heat treatment (annealing， normalizing and tempering after normalizing)， and shall be delivered smoothly.
Theoretical weight of stainless steel pipe: w = outer diameter - wall thickness x wall thickness x..
