Description
The metal ring is a kind of pressure joint seal used for oil and gas pipe flanges, pressure vessels, high speed joint surfaces, high pressure warm valve covers and the like.
There are a variety of materials and types to suit different design and operating requirements and fully comply with API 6A and ANSI B16.20 regulations. The commonly used types are stainless steel oval (Oval) and Octagonal (Octagonal). The new flat-bottomed slotted flange can be used interchangeably. The company supplies it in the shortest time.
 
The hardness of the selected metal ring material should be lower than the flange hardness of 15~20HB, and it is not recommended to reuse because the material may be hardened to damage the flange surface and affect the sealing performance.
API 6A recommends the material and maximum hardness. In addition, dual-phase steels such as Cr-Mo steel (5Cr - 0.5Mo), Monel, Inconel, Hastelloy and other special steels can also be used.
