Double metal wear-resistant elbow powder
The outer wall of the double metal wear-resistant elbow is made of seamless steel pipe and lined with high chromium alloy. Using negative pressure melting mold casting, small geometric size deviation, smooth inner wall, small pipe resistance. Lined metal brand: KmTBCr28-G, carbon content above 2.5, chromium content 26~30%, wear-resistant layer thickness 30mm, casting hardness HR above C60. The design, manufacture and acceptance of wear-resistant elbows shall comply with the power industry standard, technical conditions of wear-resistant pipes DL / T 680-1999. The deviation between the actual weight of each cast elbow and the design weight meets the national standard. Wear-resistant elbow casting rounded diameter R=5-10mm (thickened outside).
