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.

       Incoloy 925 is an age-hardened nickel-iron-chromium alloy with additions of molybdenum, copper, titanium and aluminum. The chemical composition of this alloy is designed to provide a combination of high strength and excellent corrosion resistance. The nickel content is sufficient to prevent chloride ion stress corrosion cracking. Nickel, along with molybdenum and copper, also provides significant resistance to chemical reduction. Molybdenum helps resist pitting and crevice corrosion. The chromium content of the alloy resists oxidizing environments.

Inconel 600 alloy has the following properties.        1. good resistance to corrosion by reducing, oxidizing and nitriding media        2. good resistance to stress corrosion cracking at both room temperature and high temperature        3. good resistance to dry chlorine and hydrogen chloride gas corrosion        4. good mechanical properties at sub-zero, room temperature and high temperature        5.

Introduction:Alloys comparable to Incoloy 825 alloys are high Ni, highly corrosion-resistant nickel-based alloys with extremely high corrosion resistance to both oxidizing and non-oxidizing acids.Incoloy 825 alloy has good general corrosion resistance to both oxidizing and non-oxidizing acids due to its rich content of Cr, Mo and Cu. In particular, it has extremely high corrosion resistance to sulfuric acid. Due to the high content of Cr, Mo and Ni, it has excellent pitting corrosion resistance, crevice corrosion resistance and stress corrosion cracking resistance in chloride environment.

  Inconel625 alloy is a solid solution reinforced nickel-based deformation high temperature alloy with molybdenum and niobium as the main strengthening elements, has excellent corrosion resistance and get oxidation properties, from low temperature to 980 ℃ have good tensile properties and fatigue properties, and resistance to stress corrosion under salt spray atmosphere, so it can be widely used in the manufacture of aero-engine parts, aerospace structural components and chemical equipment, the alloy is used in the manufacture of Engine magazine, guide blade, mounting edge and barrel, fue
