150class Stainless Steel 304 Flanges Welding Loose Type Flange Non Rusting

Factory Direct Stainless Steel 304 Material 150# Flanged Welding Loose Sleeve Flange

       Flanging activity flange: also called loose sleeve flange, rotary flange. Generally used in combination with flanged pipe joints. The pipe is welded to the flanged pipe joint, and the flange is set outside the flanged pipe joint. The advantage is that the flange can be rotated, easy to align the bolt hole, easy to install in large pipe diameters, flanged flange is also suitable for pipe fittings need to be removed frequently for cleaning and inspection, or used in the alignment of the flange bolt hole only need to turn the flange without rotating the pipe. When using this kind of flange, the material of the pipe joint must be consistent with the pipe, and the material of the flange is not necessarily consistent with the pipe.

This kind of flange, due to the combination of the same flanged joint, is more expensive than the same diameter, the same pressure and temperature grade flat welding flange, for especially expensive pipes, because you can use different materials of cheap materials of flanges, sometimes can achieve economic purposes.

Its resistance to internal pressure is the same as that of flat welded flange, worse than butt welded flange, fatigue life is only 10% of butt welded flange, can not be used in alternating stress occasions.

       Commonly used as a connection is a material change.
The loose sleeve flange is the use of flanging, steel ring, etc., to put the flange on the tube end, and the flange can be moved on the tube end. The steel ring or flanging is the sealing surface, and the role of the flange is to press them. It can be seen that the loose sleeve flange does not contact the medium because it is blocked by the steel ring or flanging.
The loose sleeve flange is suitable for the connection of steel, aluminum and other non-ferrous metals and stainless acid-resistant steel containers and corrosion resistant pipelines.
The loose sleeve flange is a movable flange, which is generally matched on the water supply and drainage accessories (the most common on the expansion joint). When the manufacturer leaves the factory, each end of the expansion joint has a flange, which is directly connected with the pipe and equipment in the project.
It's one of those flanges with a looper. Generally used in pipes, that way, loose bolts can rotate both sides of the pipe, and then tighten. Can be more convenient disassembly pipe. Loose sleeve flange is also called looping flange.

         304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm³; The industry is also called 18/8 stainless steel, which means containing more than 18% chromium and more than 8% nickel; High temperature resistance 800℃, with good processing performance, high toughness characteristics, widely used in industrial and furniture decoration industry and food and medical industry. However, it should be noted that compared with ordinary 304 stainless steel, food-grade 304 stainless steel has a more stringent content index. For example, the international definition of 304 stainless steel is mainly chromium 18%-20% nickel 8%-10%, but food-grade 304 stainless steel is chromium 18% and nickel 8%, allowing a certain range of fluctuations, and limiting the content of various heavy metals. In other words, 304 stainless steel is not necessarily food-grade 304 stainless steel

Among the common marking methods on the market are 06Cr19Ni10 and SUS304, of which 06Cr19Ni10 generally indicates national standard production, 304 generally indicates ASTM standard production, and SUS304 indicates daily standard production.

304 is a versatile stainless steel, which is widely used in the production of equipment and parts requiring good comprehensive properties (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel content. 304 stainless steel is a grade of stainless steel produced according to ASTM standards in the United States
