Supply & Demand

Stainless steel capillary tubes have also been an important research product of our company in recent years. Their high precision and cleanliness have earned a good reputation as puncture needles in medical orthopedic materials.

BA tube is a cold-rolled tube, which is a stainless steel tube obtained by rapid cooling under the protection of a reducing atmosphere or in vacuum after high-temperature solidification. It requires excellent surface roughness and cleanliness on both the inner and outer surfaces, and is a pipe material that comprehensively considers organizational stability, corrosion resistance, and ease of processing. The BA tube has extremely high requirements for the internal surface roughness Ra value and its own cleanliness. In addition, strict control should be exercised over the dimensional tolerance of the pipe and the chemical composition of the base material to ensure the weldability and welding quality of the steel pipe. During welding, it can reduce the occurrence of smoke and particles, and improve the corrosion resistance and smoothness of the welding area.

The company introduces internationally advanced JCOE production technology, and all production equipment is produced by domestic first-class manufacturers. It specializes in producing large diameter straight seam double-sided submerged arc welded steel pipes with a diameter of 457.2-1422.4mm, a wall thickness of 8mm 50mm, and a length of 5.8m 12.5m. The materials are ordinary carbon, special steel, and alloy steel, with the highest steel grade reaching X80. The production line adopts the full line PID automation control continuous J-C-O molding process, which is fast, high-quality, with uniform distribution of molding stress, regular tube shape, and an annual output of 150000 tons.

The steel pipe material is non-alloy low carbon steel. Pipe production technical method is ERW welded with longitudinal seam. Product standards are able to comply with ASTM A500, ASTM A53, ASTM A795, BS1387/1985 etc
