Annealing → 5. Leveling → ⒍ fine cutting → ⒎ packaging → 8. Reach customers.
After the installation of stainless steel water pipe cleaning pipeline, it is recommended to use 3% potassium permanganate for disinfection. It is strictly prohibited to use bleaching water for disinfection, 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.
.For more than 60 years, the role of stainless steel is not so eye-catching in many other applications, but in the aesthetics and performance of buildings For example, because stainless steel has more wear resistance and pressure resistance than other metal materials of the same thickness, it is the preferred material for designers when building sidewalks in places with large population flow.
Remarks: 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, etc. can be provided.
.Hot rolled stainless steel tubes are generally produced on automatic tube rolling mills. After inspection and removal of surface defects, the solid pipe blank is cut into the required length, centered on the end face of the perforated end of the pipe blank, and then sent to the heating furnace for heating and perforated on the piercer. During perforation it rotates and advances continuously. Under the action of roll and plug, a cavity is gradually formed inside the pipe blank, which is called rough pipe. Then it is sent to the automatic pipe mill to continue rolling. After that, the wall thickness of the whole machine is adjusted, and the diameter is determined by the sizing machine to meet the specification requirements. It is advanced to produce hot rolled seamless steel pipe by continuous pipe mill.
However, some people will still communicate online or by telephone to ask whether the stainless steel pipe we produce can be used as a water pipe.
Stainless welded pipe (grade y) gb3280-84 stainless cold plate (grade I)
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.
The welding alloy has good weldability. Professional stainless steel plate, stainless steel coil, stainless steel belt, stainless steel pipe, large quantity, high quality and low price. Fire resistance - Waterproof - high temperature resistance, strong and durable safe and reliable. The performance of the alloy is that the welding metal and heat deteriorated part still maintain the same corrosion resistance, strength and toughness as the base metal. It is not difficult to weld, but its welding procedure needs to be designed so that after welding, it can maintain a good phase balance and avoid the precipitation of harmful metal phase or non-metal phase. Welding can be carried out in the following equipment: GTAW (TIG); GMAW (MIG);SMAW (“stick” electrode); SAW;FCW;And paw stainless steel features: compared with L and 317L austenitic stainless steel, duplex stainless steel alloy has superior performance in spot corrosion and crack corrosion resistance. It has high corrosion resistance. Compared with austenite, it has lower thermal coefficient and higher thermal conductivity.
Installation materials.The stainless steel pipe installed on the pipeline support can be corroded by 200 ppm chloride ion and 2 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.
Compared with traditional steel, stainless steel can not only ensure high strength and weight ratio, but also have good plasticity, toughness, formability and weldability. It is the first choice for car frame. Stainless steel with superior performance can create cars with light weight, strong resistance, high safety and long service life. Such frames can be recycled and reused. It can not only save costs, but also save resources. And some other auto parts are also made of stainless steel. Stainless steel has a great potential market in the whole automobile industry!
In the building water supply pipe system, since the galvanized steel pipe has ended its glorious history of one hundred years, various new plastic pipes and composite pipes have developed rapidly. The professional stainless steel plate stainless steel coil, stainless steel belt and stainless steel pipe have advanced technology, strict testing, more affordable price and more preferential treatment. Welcome to consult. However, there are still some deficiencies in various pipes to varying degrees, It is far from fully meeting the needs of water supply pipeline system and national requirements for drinking water and related water quality. Therefore, relevant experts: building water supply pipes will eventually return to the era of metal pipes. According to foreign application experience, and the chemical composition meets the requirements
The selection of stainless steel plate shall consider the operating conditions, such as manual operation or automatic operation, the performance and type of hot press, and the quality requirements for materials, such as hardness, gloss, it is required to produce a number of decorative plates with slow quality.
Sincere service.The thickness of cold rolled steel strip is ultra-thin, and the thickness of hot rolled steel strip is large.
Human factors are also one of the causes of product oxidation that some consumers often encounter when using stainless steel products. Some consumers operate improperly in product use and maintenance, especially some stainless steel pipe products used in food and chemical equipment industry. For the artificially generated oxidation of steel products, they should have correct product use knowledge and Reasonable and effective maintenance shall be carried out regularly to reduce oxidation caused by improper use.
(soft, 1 / 23 / 4h) and other primary and secondary stainless steel coils.
.Theoretical weight: Cr Ni austenitic stainless steel austenitic stainless steel (kg / M) s-wall thickness (mm)
Stainless steel is more than twice as high and has enough plastic toughness for forming. The wall thickness of storage tank or pressure vessel made of duplex stainless steel is 30-50% less than that of common austenite, which is conducive to reducing the cost.
However, stainless steel is relative, and it is just ordinary stainless steel. It's better not to use it in a particularly polluted environment. You can rest assured to use stainless steel pipes in your daily life.
