There are about 45 types of hot rolled (hot) stainless steel pipes with a diameter of 54-480mm and 36 types with a wall thickness of 5-45mm. There are 65 types of cold drawn (rolled) stainless steel pipes with a diameter of 6-200mm and 39 types with a wall thickness of 0.5-21mm.
SPCC stainless steel belt is simply an extension of ultra-thin stainless steel plate. It is mainly a narrow and long steel plate produced to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors.
.Add a small amount of sulfur and phosphorus to make it easier to cut.
In addition to stress corrosion resistance, 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.
. 409— Cheap model (British and American), usually used as automobile exhaust pipe, is ferritic stainless steel (chromium steel).
416— The addition of sulfur improves the processability of the material.
In order to obtain seamless pipes with smaller size and better quality, cold rolling, cold drawing or a combination of both must be used. Cold rolling is usually carried out on a two high mill. The steel pipe is rolled in an annular pass composed of variable section circular groove and fixed conical plug. Cold drawing is usually carried out on a single chain or double chain cold drawing machine of 0.5 ~ 100t.
1: stainless steel plate: it can be divided into cold-rolled plate and hot-rolled plate. Its surface has bright surface, fog surface and matte surface. It is commonly known as stainless steel plate, including 2B plate and Ba plate. In addition, it can also be plated with other light colors according to customer requirements. The main specifications of plates are: 1m * 1m, 22m * 44m, 5m * 3M, 5m * 6m. If customer demand is large, we can cut them according to customer size. In addition, we can replace wire drawing plate, anti sliding plate and electroplating plate
Measures to improve the welding quality of stainless steel pipe in order to ensure that the outer surface of stainless steel pipe is not damaged and purified, the maintenance of stainless steel pipe should be strengthened in each process of consumption, mainly including the following three aspects: the processing and consumption of stainless steel pipe should have a special consumption workshop (wood board is well used) , avoid the machining platform of austenitic stainless steel and carbon steel or solid overhead.
Mold cost: specifications are commonly used but not commonly used. Common specifications are rapid turnover and low mold sharing cost. Because of low utilization and high cost sharing it is a special enterprise integrating R & D, and service

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, 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, stainless steel pipe is recognized as one of the pipes with good comprehensive performance in metal pipe. Chemical analysis: carry out chemical analysis on the chemical composition of the material, hexagonal rod, square steel, flat steel, hexagonal angle steel, round steel, solid rod. Hexagonal rod and square steel (flat steel) are more expensive than round rod (most of the hexagonal rod specifications are imported high-quality materials). The bright surface is more expensive than black leather surface. Large diameter bars are mostly black leather rods. 303 is a unique material in bars, which belongs to easy turning (cutting) materials, It is mainly used for self cutting. In addition 304f.303cu.316f also belong to easy cutting materials
This kind of steel pipe can be divided into stainless steel seamless steel pipe and stainless steel welded steel pipe (slotted pipe). According to different manufacturing processes, it can be divided into several basic types: hot rolling, cold drawing and cold rolling. According to the section shape, it can be divided into circular pipe and special-shaped pipe. Circular steel pipe is widely used, but there are also some square, rectangular, semicircular, hexagonal, equilateral triangle Octagonal and other special-shaped stainless steel pipes.
Price.& Ge; about 40 thickness: cold rolled 2B plate (0.09 & mdash; 0mm); hot rolled industrial plate No.1 (3-50mm) medium plate, chemical plate and high temperature plate; width: 5mm --- 850mm steel strip; 1000, 1211250, 1500, 1800 and 2000mm coil plate and flat plate surface: 2B smooth surface, No.1 industrial surface, BA (6K) mirror, 8K mirror 9K mirror, wire drawing surface and frosted surface.
Flux coated welding wire is used for backing welding, and argon gas is not used inside the weld. The welder's operation is simple and fast
Stainless welded disc (grade I) gb1270-80 stainless steel pipe (grade I)

Selection process of stainless steel pipe water supply pipe.
%）.It means: 100 times of Dr + iron loss value (iron loss value per unit weight when 50Hz repeated magnetization and sinusoidal magnetic induction intensity is 5T) + 100 times of thickness value. For example, dr510-50 indicates that the iron loss value is hot-rolled silicon steel plate with thickness of 0.5mm. The grade of hot rolled silicon steel sheet for household appliances is expressed by JDR + iron loss value + thickness value, such as jdr540-50.
