View ASME SA 105 Spectacle Blind Flange Dimensions And Price List EX Hebei In China.
The ASTM A105 specifies different types of flanges, which can include various grades of stainless steel material. The ASTM A105 Carbon Steel Blind Flanges are made of forged carbon steel and are ideal for high-temperature applications. We are one of the top ASTM A105 CS BLRF Flanges producers in China, capable of meeting our client’s requirements. We produce different types of carbon flanges to meet the all-around needs of various industries. Some of the standard ASTM A105 Flanges we manufacture would include:
- ASME SA 105 Spectacle Blind Flange- is a steel plate cut into two discs of a given thickness. Here, one of the disks is a solid plate, and the other one is a ring, whose diameter is the same as that of a flange.
- ASME SA 105 Tapped Blind Flange- These test flanges are made of bling flanges having tapped NPT threaded holes in the middle. These are used at the end of a piping system and can withstand a great amount of pressure.
- SA105N Slip Blind Flange- We are one of the top stockists and suppliers of slip blind flanges used when the piping system needs maintenance, modification, removal, or inspection.
- Carbon Steel Paddle Blind Flange- It has a similar solid end as a spectacle blind wherein an additional handle is welded.
- A105 Low Carbon Steel Raised Face Blind Flange- helps to concentrate larger force on a smaller area, enhancing the containment capabilities.
