2 inch stainless steel weld neck pipe flange
What is 2 inch stainless steel weld neck pipe flange?
2-inch weld neck flange forgings are produced and processed in strict accordance with relevant standards, using new technologies, new processes and new concepts, so that the advantages and performance of the flange cover meet the needs of customers, has been recognized by many users, is a commonly used flange cover.
Application
2 inch stainless steel weld neck pipe flange cover is widely used, can be used in aerospace, locomotive, ventilation pipe connection, flange connection and other uses, has the connection is not easy to deformation, high strength, durable, good material and other characteristics, can be used in fire, electric power, equipment manufacturing, shipbuilding and other industries.
What is 2 inch stainless steel weld neck pipe flange class 150?
2 “means the nominal diameter is 2 inches, refers to the flange welding end nozzle outside the diameter is 2”, which is 60.3mm, approximately equal to the metric size of DN50, but not exactly the same. #150 indicates that the nominal pressure is class150, which is 2.5MPa, equivalent to PN25 in HG/T20615-2009.
The Class marker has six pressure levels, Respectively: Class 150, Class 300, Class 600, Class 900, Class 1500, Class 2500.
What is 8 sch 40 316 stainless steel weld neck flange ?
“316 stainless steel “is a kind of material,” flange “is a kind of mechanical commonly used structure. 316 stainless steel flange is a common mechanical shaft connecting part made of 316 material.
8 sch 40 316 stainless steel weld neck flange is used to connect two kinds of pipes, fittings, or equipment, one of which is fixed to one welding. A flange pad is added between the two welds and bolted together to complete the connection. Welding is an important connection mode of high pressure pipeline construction. Weld neck flange connection is easy to use and can withstand large pressure.
The welding method requires that the weld strength at least reach the base metal strength. The weld surface is flat and smooth, without defects such as burn through, porosity, welding leakage, slag inclusion, edge biting and incomplete welding. Residual height less than 2mm.
Because it has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, freezing, sanitation, plumbing, fire fighting, electric power, aerospace, shipbuilding and other basic engineering.
