Description Flanches are connectors used to connect steel pipes to each other, to connect valves to pipes or antennas, and to connect tools such as the one-way valve of the flowmeter pressure gauge, to connect pumps, and so on. Flanges are disc-shaped pieces that are connected in pairs with the help of bolts and nuts and are easily opened and closed and are suitable for low and high pressures. The sealing between the two flanges is done by the gasket that is placed between them. Flanges are made of steel and its alloys or of cast iron, steel, etc. Other materials. The types of flange as previously described are the most widely used types of flange mentioned in ASME B 16.5 standard:: Throat Flange and Slipan Flange, Silent Weld Flange, Joint Flange Flange, Resin Flange, Rice Face Flange, Orifice Flange, Silent Flange The son, and the blind flange. According to ASME B 16.5 standard, steel flanges and alloys are classified into classes 150-300-400-600-600-900-1500. These numbers are the maximum pressure in PSI that the flanges can withstand at the maximum allowable temperature. The pressure rating is known as ISO. In this standard, the tolerance pressure of steel flanges and its alloys with PN is shown, in which the nominal pressure pressure is in BAR. The flange pressure rating is based on the BX 6-B 6-A 6 API standard. These types of flanges have a higher pressure tolerance than ANSI group flanges and are classified into classes 5000-3000-2000-155000-10000. Flanges are usually spun and made into a piece called a forge. They are made only in a few cases of sheet metal. In ASME B 16.5 standard, only blind flanges and conversion flanges can be made of weldable quality sheets. For more information, call 09339765265 Call 09123261608.
