Russia B750L plate zero cut inventory

In the first quarter of 2020, the output of EU steel pipe industry decreased by 13.3% year-on-year, but it is considered to be flexible due to its close connection with the B750L plate zero cut construction industry. However, demand for large welded pipes

In the first quarter of 2020, the output of EU steel pipe industry decreased by 13.3% year-on-year, but it is considered to be flexible due to its close connection with the B750L plate zero cut construction industry. However, demand for large welded pipes is expected to remain weak in the oil and gas industry. In 2020, the steel consumption of steel pipe industry will account for 13% of EU B750L plate zero cut steel consumption market. Uestf predicts that in 2020, the output of steel pipe industry will continue the downward trend of 2019, with a year-on-year decrease of 19.4%, and a rebound of 9.8% in 2021.

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and B750L plate zero cut pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
