Description

JIS B2220 10K Flanges

JIS B2220 is a Japanese standard for flanges used in piping systems. 10K flanges belong to a higher pressure group than 5K types, suitable for high pressure systems.

• Material : Usually made from carbon steel, stainless steel, or alloy steel.
• Size : Nominal Diameter (DN) from 10mm to 2000mm.
• Nominal pressure : 10K is equivalent to a nominal pressure of 10 kg/cm² (approximately 1 MPa or 145 psi).

Applications

JIS B2220 – 10K flanges are widely used in many industries, including:

• Oil and gas industry : Connecting pipelines for oil, gas and petroleum products.
• Chemical industry : Used in chemical handling and transportation systems.
• Water industry : Used in water supply and wastewater treatment systems.
• Shipbuilding industry : Used in piping systems on ships.
• Energy industry : Used in power plants, heat conduction systems and other energy applications.

Standards

JIS B2220 standard specifies the requirements for dimensions, pressure, materials and other specifications of flanges to ensure compatibility and safety in use. Some key points of the standard include:

• Dimensions and tolerances : Specify details of outside diameter, inside diameter, flange thickness, and bolt hole sizes.
• Pressure and temperature : Specify the nominal pressure and working temperature range for each type of flange.
• Materials : Requirements on the types of materials allowed to be used, including the physical and mechanical properties of the materials.
• Testing Methods : Provides guidance on inspection and testing methods to ensure product quality, such as pressure testing, dimensional testing, and non-destructive testing.
• Markings and labels : Regulations on marking and identification marks on flanges, including information on manufacturer, size, nominal pressure and material.
