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.

Features of Flat Welding FlangesWhen welding flat welding flanges, only one side welding is required, and there is no need to weld the inner port of the pipe and flange connection. The welding installation of butt welding flanges requires double-sided welding of the flanges. Therefore, flat welding flanges are generally used for low and medium pressure pipelines, and butt welding flanges are used for the connection of medium and high pressure pipelines. Butt welding flanges are generally at least PN2.5MPa. Butt welding is used to reduce stress concentration.

Chrome steel is bendy and stylish . it’s the preferential choice for a few of the surrounded programs and industries.The fabrication and forming approaches are fundamentals which will make stainless-steel clean for utility. hot rolling and cold rolling are the forming strategies that offer a finish to the stainless-steel surface.Stainless steel features are optimized through the use of warm rolling and bloodless rolling. the current rolling and cold rolling can improve mechanical characteristics significantly without altering its chemical composition.

Stainless steel surface treatment methods can be roughly divided into five categories, respectively, rolling surface processing, mechanical surface processing, chemical surface processing, reticulated surface processing, color surface processing. Formed products often mirror, drawing, reticulation, etching, electrolytic coloring, coating coloring, etc.

Carbon metallicCarbon metallic is primarily based on positive standards, which, if observed, might come below the carbon metal category. the few factors or the requirements to be stored in mind earlier than classifying into the identical are-There may be no specification of the minimal content material required for certain things like- nickel, titanium, cobalt, chromium, molybdenum, etc.

Stainless steel 304, 316 difference：First, 316 stainless steel containing Mo, corrosion resistance is better than 304 stainless steel in a high temperature environment, so in a high temperature environment, engineers will generally choose 316 material parts.Second, there are also differences between the two from the brand; 304 stainless steel corresponding to the Chinese brand 0Cr18Ni9; 316 stainless steel corresponds to the Chinese brand 0Cr17Ni12Mo2.Thirdly, 316 mainly reduces Cr content, increases Ni content and increases Mo2%~3%.

What is 316 Stainless Steel?Grade 316 is a famous alloy of stainless metal with a melting vary of 2,500 °F – 2,550 °F (1,371 °C – 1,399 °C). As an austenitic stainless metal alloy, it has features such as excessive strength, corrosion resistance, and excessive concentrations of chromium and nickel.
