6 Inch Blind Flange
6 Inch blind flange means the size of the blind flange is 6 inches .Blind flange is also called flange cover, also known as blind plate or blind flange. The formal name of blind disk is flange cover, which belongs to the national standard flange system. The middle of blind flange is solid, surrounded by bolt holes, and its appearance is like an iron cover, so it is also called flange cover. The stainless steel one is called stainless steel flange cover.

6 Inch Blind Flange Models
6 Inch Blind Flange
6 Inch blind flange can be flat or convex, concave and convex, tongue and groove, or ring connection, but it does not have a neck like butt welding flange (what is butt welding flange). There is also a temporary blockade when the temporary part of the pipe section needs to be tested for pressure first. Some directly add valves, and some are the original pipes that are not used now, so they are blinded with blind flanges.
Functions Of 6 Inch Blind Flange
- 6-Inch blind flange can be installed on the external thread of the pipe end, which can seal the pipe and serve as a plug. It has dustproof, waterproof and corrosion-resistant functions.
- 6-Inch blind flange mainly plays a sealing role. No additional parts are required when sealing. There are many holes around the flange cover, which are used for connection with the flange. Of course, there are also the most commonly used flange covers that are directly welded on the pipe. The periphery is made of apertures because it is convenient to assemble and can also be used for secondary use. It is also convenient for maintenance.
- 6-Inch blind flange connection is easy to use and can withstand greater pressure.
- In industrial pipelines, flange connection is widely used. In the home, the pipe diameter is small and the pressure is low, and the flange connection is invisible. If you are in a boiler room or production site, there are pipes and equipment connected by flanges everywhere.
- 6-Inch blind flange is mainly used for equipment testing, pressure testing, etc..
6-Inch Blind Flange Production Process
Generally divided into four types: forging, casting, middle plate cutting, and casting. Among them, the price of forged products is the highest, followed by the middle plate, and the lowest is casting. Casting is the worst process. The quality of forging and middle plate is good, and casting is slightly worse.
Precautions For Using 6-Inch Blind Flanges
- Under the premise of meeting the process requirements, set as few blind plates as possible.
- The blind plates set must indicate standard opening or normal closing.
- The location of the 6-inch blind flange is upstream or downstream of the cut-off valve, which should be determined according to the cut-off effect, safety and process requirements.
Connection Of 6-Inch Blind Flange
Blind flange connection is also the simplest connection method between cast iron pipes and steel pipes. Blind flanges can be used on the opening of the inspection port. In addition, blind flange connection is suitable for pipe fittings with a diameter of φ50-315mm.
Performance Characteristics Of 6-Inch Blind Flange Connection
Non-rigid connection, detachable, and tensile resistance. It is generally used on pipelines. In that case, loosening the bolts can rotate the pipes on both sides, and then tightening them can be more convenient to disassemble and assemble.
The flange made of carbon steel is called a carbon steel flange. The blind flange is a connection device for two large-diameter pipes, usually two flanges plus a number of fastening bolts. Carbon steel flange is a flange made of carbon steel. After adding an appropriate amount of carbon element, it will become hard, and the plasticity will decrease and the strength will increase.
6 Inch blind flange is a movable flange, which is usually equipped on water supply and drainage accessories (most common on expansion joints). There is a flange at each end of the expansion joint when it leaves the factory, which is directly connected to the pipes and equipment in the project with bolts, that is, the flange with a slip-on.
The 6 inch blind flange connection method is actually controlled according to the form and standard in the connection, which can show good performance advantages and value, and fully demonstrate good performance.
Determine The Type And Size Of 6-Inch Blind Flange
Based on the use conditions and media characteristics of the pipeline system, the designer needs to first determine the appropriate flange type (such as flat flange, butt welding flange, etc.) and size. When selecting the flange size, factors such as pipe diameter, working pressure, and temperature need to be considered.
Calculate The Thickness And Strength Of 6-Inch Blind Flange
Based on the selected flange type and size, the designer needs to calculate the thickness and strength of the flange. This can be done by consulting relevant standards or using professional calculation software. During the calculation process, factors such as the mechanical properties of the material and the stress condition of the flange need to be considered.
Select The Appropriate Sealing Surface Type And Gasket
The sealing performance of the 6-inch blind flange is crucial to prevent media leakage. Therefore, during the design process, it is necessary to select the appropriate sealing surface type (such as raised surface, concave-convex surface, tongue-and-groove surface, etc.) and gasket. The material and thickness of the gasket also need to be selected according to the media characteristics and working pressure. At the same time, the gasket should be placed in the center of the flange sealing surface, and it is strictly forbidden to place it off-center to ensure a good sealing effect.
