Welded Threaded Pipe Fittings

Welded Threaded Pipe Fittings are a type of fitting that combines the characteristics of welding and threaded connections,and are widely used in various pipeline systems.Below,we will provide a detailed introduction from the dimensions of definition,type,welding process,common problems,and solutions:

Definition and purpose

Welded threaded fittings are fittings with threaded interfaces that can be connected to pipes or other fittings by welding.It not only utilizes the convenience and detachability of threaded connections,but also ensures the sealing and strength of connections through welding.It is mainly used in pipeline systems to change pipeline direction,branch,connect pipes of different diameters,and close pipeline ends.

Common types

Elbows:There are different angles such as 45°,90°,and 180°,used to change the direction of pipelines,allowing them to bypass obstacles or achieve connections in different directions.

Trips:divided into equal diameter tees and reducing tees,used to achieve branching connections of pipelines,distributing fluid from one pipeline to two or more pipelines,or collecting fluid from multiple pipelines into one pipeline.

Direct head:used to connect two pipes of the same diameter,allowing the pipes to be extended.There are two types of direct heads:ordinary direct heads and reducing direct heads.Reducing direct heads are used to connect pipes of different diameters.

Pipe cap:Installed at the end of the pipeline,it serves to seal the pipeline and prevent fluid leakage or external impurities from entering.

texture of material

Carbon steel:relatively low in price,with high strength and good toughness,suitable for general industrial pipelines and building water supply and drainage systems.

Stainless steel:It has excellent corrosion resistance and can resist the erosion of various chemical media.It is commonly used in industries such as chemical,food,and pharmaceutical industries that require high corrosion resistance.

Alloy steel:By adding alloying elements such as chromium,molybdenum,nickel,etc.,the strength,hardness,high temperature resistance,and corrosion resistance of pipe fittings are improved,making it suitable for harsh working conditions such as high temperature,high pressure,and strong corrosion.
