In addition, HFW unit is with higher line speed (16m / min), while submerged arc welded steel pipe speed is generally 3m / min, which does not match.Technological innovation of HFW unit is currently mainly limited to the areas of OCTG, cold-formed steel products; Furthermore, it should develop towards the precise direction of the automobile, home appliances, chemicals, boilers, machinery and other industries, as well as in the construction, textile, agriculture and other general use series.
High frequency straight seam welded steel pipe (HFW)The advantage of HFW steel pipe lies in the after-weld heat treatment step to eliminate the residual stress of the weld and heat affected zone, grain refinement and strengthen the mechanical properties. Baosteel HFW610 unit, CNOOC Zhejiang Jinzhou Petroleum Steel Pipe HFW630 unit, Wuhan Iron and Steel Wuhan Jiangbei HFW660 unit, Dagang Oilfield in Bohai New Century HFW245 China 718 steel Manufacturers equipment unit and PetroChina Baoji Petroleum Steel Pipe SEW unit to develop high-quality OCTG, marine pipelines, oil casing and pulp pipeline all illustrate this trend. Fully utilizing and extending this advantage can improve product quality and develop new products. HFW to SAW (submerged arc welded) envisaged extending is relatively difficult.For HFW unit, the larger the diameter, the more restricted by the weight and thickness of strip material, material storage facilities is restricted by the spiral looper, so foreign mainly uses the 600 series unit to produce with “roll to roll” mode, such as Japan.
