While Chinas exported steel pipes are frequently subject to foreign anti-dumping and countervailing investigations， imported steel pipes are also constantly impacting domestic steel enterprises.
6: stainless steel strip (stainless steel coil): or coil， coil， coil， plate coil. There are many names， which is one of the reasons for oxidation of steel products. In terms of production process and product characteristics，316L stainless steel pipe forming a thin oxide film on the product surface is the basic process to avoid oxidation，316L stainless steel pipe factoryRequirements for various value materials and it is also one of the main characteristics of steel products different from other steel products. It is specialized in product sales and renewable resource sales The sales business includes: stainless steel plate， stainless steel coil， stainless steel belt and stainless steel pipe. However， when the oxide film is incomplete and discontinuous due to insufficient or negligent production process， the oxygen in the air will directly react with some elements in the product， resulting in the appearance of oxidation of the product.

Cold rolled oriented silicon steel strip consists of nominal thickness (expanded by times) + code G: ordinary material，316L stainless steel pipe P: high oriented material + guaranteed iron loss value (the value after expanding the iron loss value when the frequency is Hz and the large magnetic flux density is T by times). For example， g indicates that the thickness is .mm and the guaranteed value of iron loss is ≤ cold rolled oriented silicon steel strip. Liaocheng Suntory stainless steel provides electroplated tin plate and hot-dip galvanized plate: electroplated tin plate， electroplated tin sheet and steel strip， also known as tinplate. The surface of the steel plate (belt) is plated with tin， which has good corrosion resistance. In addition， it can be used as packaging material for cans， inner and outer sheath of cables， instrument and telecommunication parts， flashlight and other hardware.
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 -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，316L stainless steel pipe 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，316L stainless steel pipe factoryRequirements for various value materials 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
jAfter molten steel casting， stainless steel pipe fittings generally adopt the same vertical， vertical bending or arc continuous caster as carbon steel. The refined molten steel is poured into the ladle， the ladle to be poured is transferred above the tundish injection inlet through the rotary table， and then the molten steel is injected into the tundish through the long nozzle. The molten steel in tundish enters the mold through the submerged nozzle for forming， the waveform is sinusoidal， and the magnetic induction peak value is the unit weight iron loss value of T) + times of thickness value. Sometimes，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 G is added after the iron loss value to represent high magnetic induction. For example dq represents cold rolled oriented silicon steel strip (sheet) with iron loss value of and thickness of .mm. Now the new model is q.

pQMold cost: specifications are commonly used but not commonly used. Common specifications are rapid turnover and low mold sharing cost. Because of low utilization rate and high cost sharing， the specification of a group of slightly larger formed pipes used in the production of pipe molds is about -.
Allowable depth of straight track: for hot rolled and hot extruded steel pipes with diameter less than or equal to mm s stainless steel pipe and L stainless steel pipe. Therefore， it shall not be greater than % of the nominal wall thickness， and the large depth shall not be greater than .mm; for cold drawn (rolled) steel pipes it shall not be greater than the nominal wall thickness

It is generally suitable for the welding of thin plates below mm， with the characteristics of beautiful weld formation and small welding deformation.
oThe large electric clamping tool is V power supply， and the motor drives the oil cylinder to clamp. The connecting oil pipe and quick connector must not be contaminated， otherwise the dirt entering the oil circuit system will affect the normal use of the tool. Connect the main engine and hydraulic cylinder， turn on the power supply first， then tighten the pressure relief valve， wait until the pressure gauge rises to about MPa， or the main engine automatically trips， then open the pressure relief valve， turn off the power supply and remove the tong head after complete pressure relief.
