Split flange is a kind of flange, also known as split flange, which is mainly used in hydraulic machinery and often matched with nozzles

Specifications of split flange: DN15-DN80, types: A, B, C, D, E, F, H, V, eight types Pressure points: light and heavy, that is, 3000PSI and 6000PSI. Two manufacturing standards: national standard JB/ZQ4187 American standard SAE J518, international standard ISO6162ISO6164 materials are: 20 #, 304, 316L, A3 and Q235 (commonly known as carbon steel in the industry).

Split flange product color: metallic color

Product features: anticorrosion, acid and alkali resistance, long service life, reasonable price calculation, smooth surface, acid and alkali resistance, high temperature resistance, beautiful appearance and strong texture performance

Production technology: professional integral forging, forging, manufacturing medium plate, cutting, rolling, etc.

Machining methods: high-precision CNC lathe turning, ordinary lathe finishing turning, argon arc welding and other machining

Nominal pressures sch5s, sch10s, sch20s, sch30s, sch40s, etc

Manufacturing standards: national standard, American standard, Russian standard and Japanese standard, etc.

Material: 201304.316. 316L. 0Cr18Ni9. 321. 202 etc

Uses: Widely used in pipeline fittings of water conservancy and electric power stations, industrial pressure vessels, etc.

Flange pipe fittings are welded pipe fittings Such pipe fittings are used to match with pipes Some are processed and some are not processed Some castings are cast with flanges all together While the welded ones are post-processed Factory can be processed in the construction site can also be processed Pipe fittings with large and small flanges and elbow tee flange fittings Its materials are also various, such as carbon steel, alloy steel, stainless steel and so on

1. Divide by material:

Carbon steel: ASTM/ASME A234 WPBWPC

Alloy: ASTM/ASME A234 WP 1-WP 12-WP 11-WP 22-WP 5-WP 91-WP91115Mo3 15CrMoV35CrMoV

Stainless steel: ASTM/ASME A403 WP 304-304L-304H-304LN-304N

ASTM/ASME A403 WP 316-316L-316H-316LN-316N-316Ti

ASTM/ASME A403 WP 321-321H ASTM/ASME A403 WP 347-347H

Low temperature steel: ASTM/ASME A402 WPL3-WPL 6

High Performance Steel: ASTM/ASME A860 WPHY 42-46-52-60-65-70

Cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, PVCPPRRFPP (reinforced polypropylene), etc.

2. According to the manufacturing method, it can be divided into pushing, pressing, forging and casting, etc.

3. According to the manufacturing standards, it can be divided into national standard, electric standard, ship standard, water standard, American standard, German standard, Japanese standard and Russian standard

4. According to its curvature radius, it can be divided into long radius elbow and short radius elbow Long radius elbow refers to the outer diameter of a pipe whose curvature radius is equal to 1.5 times, that is, R = 1.5 D; Short radius elbow means that its curvature radius is equal to the outer diameter of pipe, that is, R=1. 0D (D is the elbow diameter R is the radius of curvature)

5. According to the pressure grade, there are about seventeen kinds of pipes that are the same as the American standard: Sch5sSch10sSch10Sch 20Sch 30Sch 40SSTDSch40Sch 60Sch 80SXS; Sch80SCH100Sch120Sch140Sch160XXS; Among them, STD and XS are the most commonly used
