ISO 9001 Welded Black Steel Seamless Pipes 16 Inch

16' High Frequency Welded Steel Pipe Building Structures ERW Steel Pipe

The forming process generally adopts the rolling cold forming method.The diameter of high frequency straight seam welded steel pipe is generally small, generally below 660mm or 26in outside diameter.It is characterized by high welding speed. For example, for steel pipes with an outside diameter of less than 1 inch, the welding speed can be up to 200 meters per minute.For 25 inch pipe with outside diameter, the welding speed can be more than 20 m/min.

According to the different welding technology of high frequency straight seam welded steel pipe can be divided into straight seam high frequency resistance welded steel pipe and straight seam high frequency induction welded steel pipe.For liquid transport: water supply, drainage.For gas transmission: gas, steam, liquefied petroleum gas.For structural use: as pile driving pipe, as bridge;

Pipes for wharves, roads, building structures, etc.ERW steel pipe is straight seam Resistance Welding pipe, English Electric Resistance Welding, abbreviated as ERW, used for transporting oil, natural gas and other vapor liquid objects, can meet the high and low pressure requirements, currently in the world's transportation pipe field occupies a pivotal position.
