Stainless Steel Pipe Flange-manufacture,factory,supplier from China

Implementation principleThreaded flange is a kind of non-welded flange, which processes the inner hole of the flange into pipe threads, and is matched with the threaded pipe to realize the connection. Compared with the flat welding flange or the butt welding flange, the threaded flange has the characteristics of convenient installation and maintenance, and can be used on some pipelines where welding is not allowed. Alloy steel flanges have sufficient strength, but are not easy to weld, or the welding performance is not good, and threaded flanges can also be selected.

Loose flange: This kind of flange is often used in the case where the medium temperature and pressure are not high and the medium nozzle is highly corrosive. The loose flange is generally used in combination with the flanging short joint, that is, the flange ring is loosely sleeved outside the flanging short joint, the pipe is butt welded with the flanging short joint, and the flange sealing surface is processed on the flanging short joint.In addition, there are flat welding ring and butt welding ring plate loose flange.

Structural features:Threaded flanges manufactured in accordance with ASME B16.5 are similar to sliding flanges, but the holes shall have tapered pipe threads in accordance with ASME b1.20.1. The thread shall be concentric with the axis of the flange opening, and the alignment deviation (perpendicular to the flange face) shall not exceed 5mm per meter. Threaded flanges are NPs 1 / 2 to NPs 24 in size and pressure classes are 150, 300, 400, 600 and 900. The sizes of class 1500 and 2500 are NPs 1 / 2 to NPs 2 - 1 / 2.Class 150 threaded flange has no counterbore.

Both are good steels for high temperature and corrosion resistance, but the 904L stainless steel pipe is much better. See the following for details:310S stainless steel pipe main composition: 25Cr-20Ni-0.08CCountry code: 0Cr25Ni20 or 0Cr25Ni20Si2310S stainless steel pipe designed for high temperature environment, oxidation resistance is better than 309S steel, used as heat resistant steel and boiler.

Stainless Steel Pipes1- Seamless Stainless Steel Pipe :Xinyuan supplies wide range of seamless stainless steel pipe for different industries such as petrochemical, oil & gas industries and other industrial applications.Stainless steel is often referred to as “corrosion-resistant steel” – it does not stain, corrode or rust as easily as normal carbon steel. It would however be misleading to say it is corrosion-proof.

Stainless steel pipe is mainly used for conveying liquid or gas pipeline system. We use alloy steel containing nickel and chromium to make steel pipes, which makes stainless steel corrosion resistant. Stainless steel tubes are oxidation resistant and are a low maintenance solution for high temperature and chemical applications. Because stainless steel tubes are easy to clean and disinfect, they also need to be used in food, beverage and pharmaceutical applications.

 In recent years, the stainless steel welded pipe market has been a "big hot". Because of its good heat transfer performance, it is widely used as a stainless steel heat exchange tube. Looking forward to the development trend of 316L stainless steel welded pipe. 　　First, the carbon content of 316L stainless steel welded pipe is 0.03, which can be used in applications where annealing after welding and high corrosive requirements are not possible. 316L stainless steel welded pipe has corrosion resistance due to the addition of molybdenum.
