After the pipeline is installed and the pressure test is qualified, it is better to wash with low chloride ion water and disinfect with 0.03% potassium permanganate.
5: stainless steel wire: it can also be called stainless steel wire, coil rod and coil yuan but it is different from stainless steel wire rope. Wire rod mainly includes spring wire and screw wire, stainless steel coil professional stainless steel plate, stainless steel belt, stainless steel pipe and other special products. It is a 20-year-old brand with advantages in price and guaranteed quality. As the name suggests: screw wire is mainly used to make screws, The spring wire is used to make springs or other hardware products required. Others, such as bright wire, hydrogen withdrawal wire, electrolytic wire, axle hairpin wire, etc. the tensile strength is 1500-2000. The hardness of spring wire is as follows: fully soft | 1 / 4 hard | semi hard | 3 / 4 hard | fully hard | extra hard. Steel wire rope gauge: 7 * 1,6 * 12,7 * 7,7 * 19,17 * 39, etc., which is higher than that of wires, rods and tubes of the same material, 304 stainless steel is a kind of high alloy steel that can corrode in air or chemical corrosion medium. Stainless steel has beautiful surface and good corrosion resistance. It does not have to go through surface treatment such as color plating, but gives full play to the inherent surface properties of stainless steel. It is used in many aspects of steel, which is usually called stainless steel. Representative properties include 13 chromium steel, 18-8 chromium nickel steel and other high alloy steels.
.When hoisting stainless steel pipes, public slings, such as hoisting belt and public collet number, shall be used. It is strictly prohibited to use steel wire rope to avoid scratching the surface; and when hoisting and placing, it shall prevent scratching caused by impact and collision. If there are surface scratches, electric arc traces and surface purification in the process of transportation, storage and processing, it must be completely cleaned, polished with an angle grinder, and then polished Polishing with optical sheet or metallographic sandpaper.
The cold rolled steel strip has good strength and yield ratio, and the hot rolled steel strip has good ductility and toughness.
.The specification and appearance quality shall comply with the provisions of gb14975-2002 stainless steel seamless steel pipe. The steel pipe is usually 5 ~ 10m long (indefinite length) hot rolled steel pipe, and the hot-rolled steel pipe is equal to or greater than 1m. The wall thickness of cold drawn (rolled) steel pipe is 0.5 ~ 0mm, 0 ~ 7m; the wall thickness is greater than 0mm, 5 ~ 8m.
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, & ldquo; No matter what kind of cat it is, catching mice is a good cat& rdquo; Professional 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. 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.
Theoretical weight of stainless steel pipe: w = outer diameter - wall thickness x wall thickness x0.02491.
Selection process of stainless steel pipe water supply pipe.
Stabilization treatment. Generally, it is used for 18-8 steel containing Ti and Nb in the solid solution treatment line. After the solid treatment the steel is heated to 850 ~ 880 ℃ for heat preservation and air cooling. At this time, the carbides of Cr are completely dissolved, while the carbides of titanium removal are not completely dissolved, and they are fully precipitated during the cooling process, so that it is impossible for the carbon to form chromium carbides again. Professional L stainless steel pipe, s stainless steel pipe and 904L stainless steel pipe ensure the quality, intergranular corrosion is effectively eliminated.
It is generally suitable for the welding of thin plates below 6mm, with the characteristics of beautiful weld formation and small welding deformation.
Where can I find it?.The Chinese brand of stainless steel plate is 0cr18ni12mo3ti (0Cr18Ni12Mo2Ti with paper should also be this brand). The new brand is 06cr17ni12mo2ti stainless steel plate. The stainless steel plate is added with Ti in SUS316 steel to improve the intergranular corrosion resistance. It is applied to the equipment of, phosphoric acid, professional stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe have stable, safe and reliable performance and can be maintenance free. The technical level has reached the domestic level and the advanced level of similar international products. Other local corrosion resistance properties are better than ferritic stainless steel.
Usage: it is widely used in automobile industry aviation industry and other departments.
The competition in stainless steel pipe industry is fierce and gradually intensified. With the flood of fresh brand blood and the downturn of market economy, it can be seen from some relevant data that the overall market potential is still great. Stainless steel pipe connection manufacturers should know how to proceed step by step and make steady progress in order to have a chance to win the market.
Economic management.2. 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, orange peel is easy to appear on the surface during deep drawing, which affects BQ performance. BQ with high hardness is relatively good.
Stainless steel pipe packing bag is nothing more than the function of protecting the surface of stainless steel pipe, so most stainless steel pipe users do not have to question this point.
Shop around and choose affordable stainless steel water supply pipes. Comparing the prices of pipes sold by various companies, the transmission energy consumption of stainless steel pipe water supply pipe is low, which saves the transmission cost, so the price will not be too expensive.
.After the stainless steel pipe is completed, it must be moved, moved and moved for a long distance. If there is no bag, there will be scratches and scratches on the surface, which will affect the appearance of the surface.
With the development of social economy, the application of stainless steel pipe has been more and more popular. It will bring new changes in various fields.
Batch size: a small number of single batch products will affect the unit price.
