Abstract: Although there are a lot of medium and small-scaled ERW pipe production plants, most of them are low technological level, incompletely equipped and poor in technical ability. Addressing this current situation, countermeasures are discussed, taking development of the ERW tubing and linepipe as an example. Also analyzed are the market prospect and restructuring of the product mix of the ERW pipes. The appropriate product size range is further defined so as to improve the manufacturing process flow of the ERW production line. Great care should be taken to the incorporation of the main operation line equipment and process with the mating operation lines(e.g., tube processing and heat treatment)for the purpose of setting up a production chain of hi-quality pro- ducts, and thus enhancing the product competitiveness.
