BL Nickel Alloy Metal Flange ASTM/UNS N08800 OD: 3" 150#

BL Nickel Alloy Metal Flange ASTM/UNS N08800 OD: 3" Class:150#

Blind flange, also known as blind flange, is actually called blind flange. It is a connection form of flange. It's actually a flange without a hole in the middle.

One of its functions is to block the end of the pipeline, and the other is to facilitate the removal of sundries in the pipeline during maintenance. In terms of sealing effect, it has the same effect as head and pipe cap. However, there is no way to disassemble the head, and the flange blind plate is fixed with bolts, which is very convenient for disassembly. Flange blind plates are made of carbon steel, alloy steel, stainless steel, plastic and so on

800ht further modified the total content of titanium and aluminum (. 85-1.20%) to ensure the best high temperature performance. Nickel alloy is double certified (800H / HT) and has the characteristics of both forms. N08800 alloy is suitable for high temperature structural applications. Nickel content makes the alloy susceptible to chloride stress corrosion cracking and corrosion σ The embrittlement of phase precipitation is highly tolerated. Generally, it has excellent corrosion resistance. Under the condition of solution annealing, 800H and 800ht alloys have excellent creep and stress rupture characteristics.
