316L stainless steel pipe is a hollow strip of round steel, which is mainly used for petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial pipeline and mechanical components.
304L stainless steel pipe belongs to the international stainless steel marking method. 304L stainless steel tube --S30403 (American AISI, ASTM) 304L corresponds to the Chinese brand is 00Cr19Ni10, characteristics and uses: lower than 0Cr19Ni9 carbon content steel, intergranular corrosion resistance is superior, after welding is not heat treatment parts.
321 stainless steel pipe is made of 321 stainless steel.
321H stainless steel pipes are applied to open-pit machines, building materials, heat-resistant parts and difficult parts for heat treatment, which are highly resistant to grain boundary corrosion.
304 stainless steel pipe as a stainless steel heat resistant steel is used for food equipment, general chemical equipment, and atomic energy industrial equipment. 304 stainless steel is more resistant to rust than 200 series of stainless steel. High temperature resistance is also better, can be up to 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and better intergranular corrosion resistance.
310S stainless steel pipe is a kind of hollow circular steel, which is widely used in oil, chemical, medical, food, light industry, mechanical instruments and so on. When the bending and torsion strength are the same, the weight is lighter, and it is widely used to manufacture mechanical parts and engineering structures. It is also often used as a conventional weapon, barrel, shell, and so on.
The 317 stainless steel tube is a brand of stainless steel produced in accordance with the ASTM standard of the United States. It is equivalent to the 0Cr19Ni13Mo3 stainless steel tube in our country. 317 chromium containing 19%, containing nickel 13%, containing molybdenum 3%.
317L stainless steel tube is a brand of stainless steel produced according to the American ASTM standard. It belongs to the heat-resistant steel, and 317L is equivalent to the 00Cr19Ni13Mo3 stainless steel tube in our country. 317 chromium containing 18.0-20.0%, containing nickel 11.0-15.0%, containing molybdenum 3.0-4.0%.
The stainless steel seamless tube is a strip of steel with hollow section and no joint in the surrounding area. The thicker the wall thickness of the product, the more economical and practical, the thinner the wall, its processing cost will increase greatly.
Stainless steel welded pipe, referred to as welded pipe, commonly used steel or steel strip through the unit and mold curled forming of the steel pipe. The welding steel pipe production process is simple, the production efficiency is high, the variety specification is many, the equipment investment is few, but the general strength is lower than the seamless steel pipe.
304 stainless steel welded pipe as a stainless steel heat resistant steel is used for food equipment, general chemical equipment, and atomic energy industrial equipment. 304 stainless steel is more resistant to rust than 200 series of stainless steel. High temperature resistance is also better, can be up to 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and better intergranular corrosion resistance.
The welded pipe is called the welded pipe for short, and the commonly used steel or steel strip is welded by the curled forming of the unit and the mold.
The three stainless steel is a pipe fittings and a pipe connection. Used in the main pipe to the branch pipe. With the diameter stainless steel three and reducing the points, to take over the end of three equal diameter pass are the same size; different diameter three pass charge the same size, and the size is smaller than the head of branch pipe pipe size.
Flanges (Flange) are also called flanges or flanges. A flange is a part that connects the pipe to the pipe, which is connected to the end of the tube. There are holes in the flange, and the bolts make the two flanges close. The flange is sealed with a cushion. Flange threaded connection (wire connection) flange and welded flange.
The difference between stainless steel elbow and carbon steel elbow is mainly due to the different material. Its chemical composition will keep the elbow surface for a long time without rust and will not be corroded.
The four - way stainless steel refers to a pipe joint made of stainless steel, a pipe used in the branch of a pipe.
A stainless steel joint is a kind of stainless steel joint.
