Flat welding flange with diameter butt welding flange with diameter flat welding flange blind plate

Description :

Flanges, also known as flanges or flanges, are key fittings for detachable connections between pipelines, valves, and equipment.

Tighten the two components together with bolts and washers to achieve sealing and connection.

1、 Main function

1. Connection: Connect pipelines, valves, pump bodies, equipment, etc. into a piping system.

2. Sealing: Cooperate with gaskets to ensure that the pipeline does not leak under pressure and temperature.

3. Easy to disassemble and assemble: convenient for later maintenance, replacement, and upkeep.

2、 Common types

-Plate type flat welding flange: easy to process, low cost, mostly used for medium and low pressure pipelines.

-Flat welding flange with neck: higher strength, suitable for a wider range of pressure and temperature.

-Neck welding flange: With good rigidity and reliable sealing, it is suitable for high pressure, high temperature, flammable and explosive working conditions.

-Blind flange (blind flange): used to block the end of the pipeline for easy opening in the later stage.

-Threaded flange: No need for welding, direct threaded connection, suitable for places where welding is not advisable.

3、 Common materials

-Carbon steel: 20 #, Q235, 16Mn, etc

-Stainless steel: 304, 316L, 321, etc

-Alloy steel, low-temperature steel, special alloys

4、 Execution standards

GB, HG, SH, JB, ASME B16.5, ANSI, DIN and other domestic and international standards.

5、 Application scenarios

Petroleum, chemical, natural gas, electricity, metallurgy, water supply and drainage, HVAC, ships, etc

All industrial and civilian systems that require pipeline connections, sealing, and easy maintenance.
