Elbow pipe fittings in welding type need to pay at

Elbow pipe fittings in welding type need to pay attention to matters:

Elbow pipe fittings in the pipeline connection, mainly welding matters need to pay attention to is divided into: national standard elbow in order to prevent the different erosion of elbow fittings because of heating, welding current should not be too large, less than about 20% carbon steel electrode, arc should not be too long, fast cooling between layers, with narrow welding is appropriate.

The stamping elbow in the elbow pipe fittings after welding hardening is larger, easy to produce cracks, using the same type of stamping elbow welding, must carry out preheating above 300 degrees Celsius and about 700 degrees Celsius after welding slow cooling treatment, welding parts can not carry out heat treatment after welding, should choose stamping elbow electrode.

In the installation can also be directly connected with the flange flange connection device on the pipeline, according to the use of the installation.Series Elbow Flow Using Elbow Sensor Elbow Flowmeter, Main Engine Differential Pressure Edge Feeder and Some Pipe Valve Assembly Construction.

The production and application of wall thickness elbow production and application of stamping forming elbow is an earlier production technology in the production of elbow and pipe. At present, the production technology of the company in the production of elbow and pipe is advanced technology and equipment to produce various specifications and models of elbow and pipe.The main role of elbow fittings in pipeline installation is to enable the pipeline to do any Angle of turning.The above briefly introduces the matters needing attention when welding elbow pipe fittings and the role of prayer in pipe installation.The type of connection used during installation is that.
