Durable JIS slip on flange This flange is a Japanese standard 2-inch carbon steel flange with rust resistance and durability. At the same time, our company has advanced equipment, which provides a basis for manufacturing excellent flanges and has obtained various qualification certificates. The industrial processes come into die forging,and machining,we can provide a wide range of slip on weld flanges,following on standards like ASME B16.5 Flange, ASME B16.47 Flange, DIN 2573 Slip On Flange, DIN 2631 Welding Neck Flange, JIS Flange 5K SOP Flange and JIS Flange 10K SOH Flange. Slip on flange is a type of flange that extends steel pipes, pipe fittings, etc into the flange and connects with equipment or pipelines through fillet welds. This flanges have short neck, which increases the strength of the flange and improves the bearing capacity of the flange. So it can be used on higher pressure pipelines. ASME Flange include ASME B16.5 Flange, ASME B16.47-A Flange, ASME B16.47-B Flange, this standard system include slip on flange, blind flange, welded neck flange, threaded flange, lapped joint flange (loose flange), socket welded flange, B16.36 Orifice Flange, long weld neck flange and special flange, sizes from 1/2 inch to 60 inch, class 150, class 300, class 600, class 900, class 1500, class 2500.

BS4504 Slip on are commonly lower in price than weld neck flanges, and to this effect are a popular choice for our customers. It is welded both inside and out to provide sufficient strength and prevent leakage. Slip on pipe flanges as made obvious by their name, these pipe flanges slip over the pipe. They are manufactured with inside diameter that is slightly bigger than the pipe's outside diameter. These attachments are connected to the pipe via fillet weld at the top and bottom of the flange. However customers should bear in mind that this initial cost saving may be diminished by the additional cost of the teo filet welds required for proper installation. Moreover, weld neck flanges have a higher life expentancy than slip on flanges under duress. Slip on flanges are all bored slightly larger than the OD of the pipe. They are preferred over welding neck flanges but many users due to their lower intial cost, but final intallation cost is probably not much less than that of the welding neck flange because of additional welding involved.

DIN2527 Blind flange is used to close ends of piping systems. It is a kind of round plate with no center hold but with all the proper bolt holes. This blind flange is available in various sizes and materials and is used to provide positive closer on the ends of pipes, valves or equipment nozzles. This flange helps in easy access to A Line once it has been sealed. The blind flange is sometimes custom made or machined to accept a nominal sized pipe to which reduction is being made. This reduction can be a threaded reduction or welded reduction. Blind flanges are sometimes supplied with NPT fittings which allow pressure test connections to be fitted. They are used to blank off the ends of pipe. They are also used to blank off the ends of valves and pressure vessel opening. Considering factors like internal pressure and bolt loading, blind flanges, especially in the larger sizes, are the most highly stressed of all types of flanges. Since the maximum stresses in a blind flange are bending stresses at the center, they can safely be allowed to be higher than in other types of flanges. Blind flanges are made to fit standard pipes in all sizes.

Long welding neck flange is the neck height is higher, which improves the rigidity and bearing capacity of the flange. Compared with butt welding flanges, the welding workload is large, the welding rod consumption is high, and it cannot withstand high temperature and pressure, repeated bending and temperature flutuatuins, but it is more convenient for onsite installation and omit the process of welding seam scratching, which is more popular. Long welding neck flange is similar to a standard welding neck flanges, but the neck is considerably longer than other flanges. LWN flange is often used as a nozzle for a barrel or column. This is the most common type of high pressure pipe flange. They are distinguished from other types of pipe flanges by their long tapered hub and gentle transition of thickness in the region of the butt weld joining them to the pipe. The long tapered hub provides an important reinforcement of the weld neck flange proper in terms of strength and resistance to dishing.

JIS Blind flange are used to blank off the ends of piping, valves and pressure vessel opening. From the standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed of all flange types. Blind flange is also used in the flange of the import and export of the equipment, which is used to connect the two equipment. Blind flange is used to close ends of piping systems. It is kind of round plate with no center hold but with all the proper bolt holes. This blind flange is avaliable in various sizes and materials and is used to provide positive closer on the ends of pipes, valves or equipment nozzles. This flange helps in easy access to a line once it has been sealed. The blind flange is sometimes custom made or machined to accept a nominal sizes pipe to which reduction is being made. This reduction can be a threaded reduction or welded reduction.

Spectacle and line blind flanges are similar to a blind flange but different because they fit between two flanges. Spectacle blind gets their name from similarity to pair or eye glasses. Once side of spectacle blind flange is fully closed for complete flow shuts off, whereas the other end is open for full flow. In this setup the blinds can be rotated without having to take the system apart. It also gives visual confirmation if the line is open or close.

British standard BS10 specification for flange and bolting for pipe, valves, and fittings. This covers plain, boss, integrally cast or forged, and welding neck type flanges, in ten tables. Although BS 10 is obsolescent, it remains in use for the dimensions of light duty, economy stainless steel flanges in applications where corrosion resistance and/or hygiene, rather than high pressures and temperatures, are the primary considerations. The following tables details the applicable standard dimensions from tables D,E,F and H of BS10. Surface treatment of flange: the yellow painting flange flange is bright and dazzling, it is needed in the markets of south east of Asia and Africa; black painting flange looks more seriously than other colors, it is needed in the markets of south east and mild east of asia; anti rust oil flange is most markets of the world, and it is the cheapest treatment method.

EN1092-1 type11 welding neck flange are distinguished from other types by their long tapered hub and gentle transition of thickness in the region of the butt weld joining them to the pipe. The long tapered hub provides an important reinforcement of the flange proper from the standpoint of strength and resistance to dishing. The welding neck flanges are normally refered to as the high hub flange. It is designed to transfer stress to the pipe, thereby reducing high stress concentrations at the base of the flange. The welding neck flange is the best designed butt welded flange of those currently avaliable because of its inherent structural valve. It is expensive because of the design.

Aluminum Welding neck flanges are flanges that designed to be joined to a piping system by butt welding. The weld neck flange is relatively expensive because of its long neck, butt is prefereed for high stress applications. The neck, or hub, transmits stresses to the pipe, reducing stress concentrations at the base of the welding neck flange. The gradual transition of thickness from the base of the hub to the wall thickness at the butt weld provides importamt reinforcement of the weld neck flange. The bore of the weld neck matches the bore of the pipe, reducing trubulence and erosion.

Aluminum flange is a method of connecting pipes, valves, pumps and other equipment to form a pipework systems. It is the machinery, petroleum, chemical, water, electricity, shipbuilding sectors piping systems and devices most widely used pipe fittings. Flange is the parts which connects two pipe ends, flange connection is defined by the flange, gasket and bolt three are connexted as a group of combined sealing structure of the detachable connection. The gasket is added between the two flanges and then fastened by bolts. Different pressure flange, thickness is different, and the bolts they use are different.
