Cangzhou Bohai Pipe Co., Ltd. specializing in the production of wear-resistant elbow technical parameters density ≥3.6 g / cm3 Rockwell hardness ≥85 HRA Compressive strength ≥850 Mpa fracture toughness KΙC ≥4.8MPa · m1 / 2 flexural strength ≥290MPa thermal conductivity of 20W / mK thermal expansion coefficient: 7.2 × 10-6m / mK Cangzhou Bohai Pipe Co., Ltd. specializing in the production of wear-resistant elbow wear elbow corrosion, anti-fouling since the steel ceramic layer (a-AL2O3), is neutral trait . So with acid and resistance to seawater corrosion, wear elbow, and also has anti-fouling properties. Good performance since the alumina ceramics (a-AL2O3), a single stable crystal structure. So that the composite tube long-term normal operation within -50--900 ℃ temperature range. Linear expansion coefficient of 6-8 × 10-6 / 0C, around about 1/2 of steel. Material has good thermal stability. Wear elbow DN300_ wear elbow _ Ltd. Cangzhou Bohai Bohai Sea by Cangzhou tube. Cangzhou Bohai Tube Co., Ltd. (www.czbh628.com) (www.hbbh628.com) strong, credible, three-way, etc. Hebei Cangzhou accumulated a large number of loyal customers. The company better work attitude and constantly improving Cangzhou Bohai innovative ideas will lead into the brilliant and you work for a better future!
