KovolaRound edge stainless steel stripBasic knowledge of the product

Continuous casting shall be adopted for stainless steel pipe fittings, so as to improve the comprehensive yield, and cooperate with out of furnace refining, which significantly improves the production efficiency, omits the blank opening process and saves a lot of energy consumption.Household worries.Kovola,The existence of medium temperature brittle zone requires strict heat treatment and welding process system to avoid the appearance of harmful phase and damage the performance.According to the purpose,KovolaDN15 stainless steel pipe, it can be divided into oil well pipe (casing, oil pipe and drill pipe), pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe,Kovola304 stainless steel hose, gas cylinder pipe, chemical pipe (high-pressure chemical fertilizer pipe, petroleum cracking pipe) and marine pipe.Bougado,Decorative stainless steel pipe: usually the outer wall is relatively bright, so its name is considered. Decorative stainless steel pipe is used for decorative purposes. The stainless steel pipe for general decorative purposes is relatively thin. Because it is different from the manufacturing process of stainless steel product pipe, the price also varies greatly. The general production process of decorative stainless steel pipe is ordinary welded stainless steel pipe. Guangdong stainless steel product pipe stainless steel product pipe: generally, the surface of stainless steel product pipe is also a bright surface, and a small number of pipes with acid pickling industrial surface. As mentioned above, stainless steel product pipe belongs to the purpose of stainless steel products because the outer diameter size, mechanical properties, acid, alkali and corrosion resistance of stainless steel pipe are relatively good, stainless steel pipes are generally used as anti-corrosion materials or hardware products in large-scale production enterprises. The production process of stainless steel pipes is one-time forming, and nitrogen protection is also added during welding.Add a small amount of sulfur and phosphorus to make it easier to cut.Stainless steel export is an important part of China's export economy. It plays an important role in stimulating China's economic growth. However, from the current situation of China's stainless steel foreign trade, China's stainless steel export has encountered great resistance.

First of all, steel that will not rust is called stainless steel,Kovola600 stainless steel plate, but in an academic sense, steel resistant to weak corrosive media such as air, steam and water and chemical corrosive media such as acid alkali and salt. Also known as stainless acid resistant steel. In practical application, the steel resistant to weak corrosion medium is often called stainless steel, while the steel resistant to chemical medium is called acid resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical medium corrosion, while the latter is generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. Chromium is the basic element for stainless steel to obtain corrosion resistance. When the chromium content in the steel reaches about %, chromium reacts with oxygen in the corrosive medium to form a thin oxide film (self passivation film) on the steel surface, which can prevent further corrosion of the steel matrix. In addition to chromium the commonly used alloy elements include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., so as to meet the requirements of various uses on the microstructure and properties of stainless steel. 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.The back is blocked with blocking plate for ventilation protection; Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection; Use flux cored wire for backing TIG welding.Installation works,Stainless steel pipes and water transmission equipment for fluid transportation such as water and gas are advanced basic water purification materials in the world. They have strong anti-corrosion performance, which can not be compared with cast iron pipes, carbon steel pipes and plastic pipes.Standard classification - classification: national standard GB industry standard Yb local standard enterprise standard qcb- classification: product standard packaging standard basic standard - standard level (divided into three levels): y level: international advanced level I level: international general level H level: domestic advanced level - national standard: stainless steel bar (level I) gb- stainless welding disc Park (level H)Stainless steel pipe can be divided into equal section pipe and variable section pipe according to the profile shape. Variable section pipes include conical pipes, stepped pipes and periodic section pipes.

Marking: in order to make the steel pipe complete the socket of the pipe fitting, the length must be marked and marked at the pipe end.Inspection basis,Add a small amount of sulfur and phosphorus to make it easier to cut.After the pipeline is installed and the pressure test is qualified, it is better to wash with low chloride ion water and disinfect with .% potassium permanganate.There are various connection modes of stainless steel pipes. The common types of pipe fittings are compression type, compression type, union type, push type, push thread type, socket welding type, union flange connection, but most of them are easy to install, firm and reliable. The sealing ring or gasket materials used for connection are mostly silicone rubber, nitrile rubber and EPDM that meet the requirements of national standards. L stainless steel pipe, s stainless steel pipe, L stainless steel pipe and other brand products are provided for a long time. The designated products are complete and the quality is guaranteed,Model & mdash; Except that the risk of weld corrosion of the material is reduced due to the addition of titanium, other properties are similar. Stainless steel decorative pipe, stainless steel pipe, series stainless steel pipe & mdash; Ferritic and martensitic stainless steel model & mdash; Good heat resistance, weak corrosion resistance, % Cr, % Ni.The manufacturing and maintenance of equipment consume more than tons of stainless steel pipe. This kind of industry mainly adopts sanitary or grade stainless steel pipe. The sanitary seamless pipe made of imported sus and l can meet the special requirements of various media in the field of food and biopharmaceutical. Stainless steel has the advantages and good performance of stainless steel. It is widely used in kitchen equipment, workbench, utensils and medical instruments in the food industry The demand for tableware, towel hanging bracket and bracket of refrigerator in daily life is increasing.The best way to improve the quality of stainless steel pipe fittings is to change the process from ingot to billet. Due to the improvement of continuous casting process this has become a necessary means to improve product quality.
