2 inch stainless steel weld neck pipe flange

What is 2 inch stainless steel weld neck pipe flange?

2-inch weld neck flange forging is a commonly used flange cover, which refer to the flange with a neck and a round tube transition and welded to the pipe.

Application

2 inch stainless steel weld neck pipe flange cover is widely used. It can be used in aerospace, locomotive, ventilation pipe connection, flange connection and so on. Moreover, It also can be used in fire, electric power, equipment manufacturing, shipbuilding and other industries.

Features

It has the connection is not easy to deformation, high strength, durable, good material and other characteristics.

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. 

Class150 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 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.

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. The other is to add a flange pad between the two welds and bolt them together to complete the connection.

In fact, welding is an important connection mode of high pressure pipeline construction. And 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.

Application:

It has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, petroleum, light and heavy industry, plumbing, fire fighting, electric power, aerospace, shipbuilding and other basic engineering.
