After the installation of stainless steel water pipe cleaning pipeline， it is recommended to use % potassium permanganate for disinfection. It is strictly prohibited to use bleaching water for disinfection
After the installation of stainless steel water pipe cleaning pipeline， and clean it with clean water after disinfection. If it is not put into use for a short time， compressed air must be used to blow out the residual water in the pipe， so as to prevent the corrosion reaction between oxygen free in the pipe and other media.
7Stainless welded disc (grade I) gb- stainless steel pipe (grade I)
vThe back side is not protected by argon， and the flux coated welding wire (self protective flux cored welding wire) + TIG process is adopted. In the s，304 stainless steel plate the backing welding wire has been developed. Recently，Quotation of stainless steel pipeReduce radioactive pollution China has also developed the stainless steel backing welding wire (i.e. flux coated welding wire， such as tgftgftgftgf， etc.) It has been applied to the actual construction and achieved good results. We have successfully applied it in the capacity expansion and reconstruction project of Urumqi Petrochemical.
Cold formed alloys can be cut and cold formed. However， the alloy needs cold forming more than austenitic steel. Because of its high strength， springback should be fully considered.
JLa Rochelle (VI) the growth rate of fixed asset investment in the iron and steel industry dropped significantly. From to June， the investment in fixed assets in the iron and steel industry was . billion yuan， a year-on-year increase of %， of which the investment in ferrous metal smelting and rolling was . billion yuan， a year-on-year increase of %，304 stainless steel plate down percentage point from the same period in ; The investment in ferrous metal mining and dressing was . billion yuan， a year-on-year increase of %， and the growth rate fell sharply by percentage points.
PiThe specification and appearance quality shall comply with the provisions of gb- stainless steel seamless steel pipe. The steel pipe is usually ~ m long (indefinite length) hot rolled steel pipe， and the hot extruded steel pipe is equal to or greater than m. The wall thickness of cold drawn (rolled) steel pipe is . ~ mm， ~ m; the wall thickness is greater than mm ~ m.
— The corrosion resistance is the same， and the strength is better because the carbon content is relatively high.
Mold 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， it is a special product manufacturing enterprise integrating R & D， sales and service. It has long been specialized in selling L stainless steel pipe， s stainless steel pipe and L stainless steel pipe. Therefore， the specification of a group of slightly larger formed pipes used in the production of pipe molds is about -.
bThe domestic prospect is promising，304 stainless steel plate the demand for each pipe is ~ km from to ， including km of cold and hot water pipes in residential construction areas. Some people believe that the development of stainless steel water pipes is of great significance to improve the grade of modern urban buildings.
RIts alloy composition (chromium，Quotation of stainless steel pipeReduce radioactive pollution nickel， titanium， silicon， aluminum， etc.) and the internal structure of stainless steel coil plate are mainly composed of chromium. Chromium has high chemical stability， can form a passive film on the steel surface， isolate the metal from the outside， protect the steel plate from oxidation and increase the corrosion resistance of the steel plate. After the passivation film is destroyed，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 the corrosion resistance decreases.
LClick to viewCold rolled oriented silicon steel strip consists of nominal thickness (expanded by times) + code G: ordinary material， 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， Chinas stainless steel industry should protect its rights on the one hand， but it is important for Chinas stainless steel industry to continuously improve its own quality level and comprehensively upgrade.
In view of the continuous vibration of stainless steel pipe shopping malls， even & ldquo; Roller coaster & rdquo; Market， stainless steel pipe market participants are implementing it carefully & ldquo; Fast forward and fast Exit & rdquo; Therefore， the national stainless steel pipeline inventory has been at a low level. High price sales of various specifications of stainless steel plate， stainless steel coil， stainless steel belt and stainless steel pipe. Waste sellers， industrial companies， enterprises and power departments are welcome to visit and negotiate with the company! At the beginning， the social inventory of stainless steel pipes should progress with the progress of economic aggregate， and with the progress of total output and demand. However， or even did not increase， indicating a relative decline in social inventory level. Low inventory has indeed played a role in market stability.
Relevant information stainless steel export is an important part of Chinas export economy. It plays an important role in stimulating Chinas economic growth. However， from the current situation of Chinas stainless steel foreign trade， Chinas stainless steel export has encountered great resistance.
market prices physical properties chemical composition C: it is specified in， which is usually also called moti or mechanical properties ys (MPA)
TWhen the stainless steel pipe with solid core welding wire is prefabricated， the welded junction can usually be rotated for welding， and the ventilation is very easy. At this time， the blocking plate is usually used to block both sides of the welded junction in the pipe， and the bottom welding is carried out for the protection of ventilation (see Table )， and the outside is blocked with adhesive cloth.
The steel grades for JIS mechanical structures are: S + carbon content + letter code (CK)， in which the carbon content is represented by the intermediate value & times; ， and K: represents steel for carburizing. For example， the carbon content of carbon coil sc is .-.%. The grades of silicon steel sheets in China and Japan are.
m 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.
gWHot dip galvanized sheet hot dip galvanized sheet， which immerses the sheet into the molten zinc bath to make its surface adhere to a layer of zinc. It is mainly produced by continuous galvanizing process， that is the rolled steel plate is continuously immersed in the zinc melting bath to make galvanized steel plate. Liaocheng Suntory stainless steel plate weighing method: stainless steel plate: thickness (mm) x width (m) x Length (m) x density stainless steel plate: thickness (mm) x width (m) x Length (m) x density stainless steel plate: thickness (mm) x width (m) x Length (m) x density stainless steel basic weight (density)
B cold rolling shall be subject to heat treatment， pickling or similar treatment， and then leveled to obtain appropriate gloss.
