Plate type flat welding titanium flange
Advantages:Convenient materials, simple manufacturing, low cost, widely used.
Disadvantages:Rigidity is poor, so it can not be used for supply and demand, flammable, explosive and higher vacuum requirements of the chemical process piping system and high, extreme harm occasions.
Sealing surface types are flat and abrupt.
Two. Flat welded titanium flange with neck
Advantages:Site installation is more convenient, can omit the welding seam patting kneading process.
Disadvantages:The neck height of the flat welding flange with neck is lower, which improves the stiffness and bearing capacity of the flange. Compared with butt-welding flange, welding workload is large, electrode consumption is high, can not withstand high temperature, high pressure and repeated bending and temperature fluctuations.
Titanium butt welding flange with neck
The sealing surface forms of neck butt welding flange are:
Face (RF), Concave (FM), Convex (M), Tenon (T), Groove (G), Full plane (FF).
Advantages:The connection is not easy to deform, good sealing effect, widely used, suitable for the temperature or pressure fluctuations of the pipeline or high temperature, high pressure and low temperature pipeline, but also used for conveying expensive medium, flammable and explosive medium, toxic gas pipeline.
Disadvantages:The neck butt welding flange is huge in volume, heavy in weight, expensive in price, and difficult in installation and positioning. So they are more likely to bump in transit.
Fourth, integral titanium flange
Integral flange is a way of connecting flange. It also belongs to a neck butt welding steel pipe flange. Material has carbon steel, stainless steel, alloy steel and so on.
In various domestic standards, the IF is used to represent the integral flange. It is mostly used in high pressure pipelines. The production process is generally cast.
In the flange type, an "IF" is used to indicate the overall flange type.
Generally, they are convex and concave surfaces (MFM) and tenon and groove surfaces (TG) in addition to RF surfaces, if they are used in flammable, explosive, high and extremely harmful working conditions.
