ERW Steel Pipe

Classification :

ERW steel pipe is a straight seam electric resistance welded pipe, abbreviated as ERW pipe, which is a round pipe welded by steel plates. It is used to transport vapor and liquid objects such as oil and n atural gas, and can meet various requirements of high and low pressure.
