Loose Flange-manufacture,factory,supplier from China

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.

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.

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.

In the range of 25-300℃, with the increase of deformation temperature, the strength and elongation of the prepared materials decrease gradually in hot rolled, cold rolled and solid solution states. The reason may be that the rise of temperature, the increase of stacking fault energy and the change of deformation mechanism from twinning to slip. 4.210-4-6.

Stainless steel and nickel are two common materials in numerous industries. Each material has its own set of advantages and disadvantages. In the grand plan of things, it determines which one you consider.What is stainless steel?Stainless steel is a series of alloys with specific carbon and chromium contents.

304 stainless-steel is a common stainless-steel material, density of 7.93 g/cm³, the enterprise is likewise referred to as 18/8 stainless-steel.

Differences between 410 stainless steel and 304 stainless steel410 stainless steel and 304 stainless steel are common stainless steel grades, which are different in composition, performance, use, etc.304 stainless steel contains more metal element nickel (Ni) than 410. It has better corrosion resistance and oxidation resistance, better stability, and is widely used in industrial and household decoration and daily tableware; The 410 stainless steel has higher carbon content, better strength and hardness, and stronger magnetism.

Stainless steel rolls in accordance with the method of classification can be divided into cold rolling and hot rolling two, if it is in accordance with the structural characteristics of steel classification, can be divided into 4 categories, respectively, austenitic stainless steel, ferritic stainless steel, martensitic stainless steel and precipitation hardening stainless steel.Cold rolled stainless steel coil in order to ensure its yield strength, tensile strength, elongation and hardness and other mechanical properties, steel coil in the production of the need to undergo annealing and solut
