Recently, seamless pipe diameter 159mm seamless steel pipe production line has successfully rolled J55 (32Mn6) oil pipes for the first time. The first batch of products has been sent to Shaanxi Yanchang Oilfield recently. The successful rolling of the J55 (32Mn6) oil pipe added new members to the Baosteel oil special pipe. At this point, Baotou Steel can produce a full range of petroleum-specific pipes.

Petroleum pipes, that is, seamless steel pipes used for underground oil and gas drilling or transportation of petroleum, are comparable to ordinary seamless steel pipes, whether they are production standards or performance, such as tensile strength, pressure resistance, impact force, bending, etc. Strict regulations. As the tubing is buried deep underground, if there are quality problems, the cost of replacement or repair is huge.

According to Wu Minghong, the deputy director of the seamless factory, after the 159 mm diameter seamless steel pipe production line is put into operation, Baotou Steel has fully equipped the ability to produce oil pipes. Based on this favorable condition, seamless factories actively debug equipment, adjust operating parameters, and try to roll new products. Prior to this, Baotou Steel was able to roll special oil pipes such as oil casing pipe, oil drill pipe and couplings, and the successful rolling of the J55 (32Mn6) oil pipe filled the gap in the production of hot-rolled oil pipes.

According to Liu Shilong, chief of the seamless steel pipe sales department of Baotou Steel Sales Company, the total amount of this oil pipeline contract is 1,120 tons, which is used by two subsidiaries of Shaanxi Yanchang Oilfield. At present, Baosteel sales companies increase
