Steel Pipe In High Frequency Welded Steel Pipe For Oil And Gas
Pipeline
Product Description
High Frequency Welded process is to use the skin effect to concentrated on the steel
object surface, use proximity effects to control the position and
the power of the high-frequency electric current flow path. Since
the speed is very high, the contacted plate edge could be heated
and melted inshore time, then extruded through the docking process.
The high-frequency welding (HFW) is mainly used in ordinary or thin
wall steel pipe. It includes contact welding and induction welding.
Direct current welding is generally used for small-caliber steel
tubes.
Resource:
testing facilities for fracture mechanics studies
corrosion & metallurgical test equipment
non-destructive testing
process advice & troubleshooting
tailored training courses
Application Areas
HFW welded steel pipes are widely preferred in Oil, Natural Gas,
Water and other liquids transportation and distribution lines,
heating, cooling, ventilation piping and steel structures for
construction and other general purposes by means of precise
production tolerances and high capacity manufacturing method.
