Steel flange
Đặc điểm kỹ thuật ASTM A193 bao gồm các vật liệu bu lông đinh tán bằng thép hợp kim và thép không gỉ cho dịch vụ nhiệt độ cao hoặc áp suất cao.
Common materials for pipe flanges (forged grades): ASTM A105 (high temperature carbon steel to match A53 / A106 / API 5L pipes), A350 Grades LF1 / 2/3 (low temperature carbon steel). to fit A333 pipes), A694 Grades F42 to F80 (high yield carbon steel to fit API 5L pipes), ASTM A182 Grades F5 to F91 (alloy steel flanges to fit A335 pipes) ), A182 Grade F304/316 (stainless steel flange to match SS12 pipe), A182 Gr. F44/F51/F53/F55 (duplex and super duplex to match A790/A928) and various nickel alloys (Inconel, Incoloy, Hastelloy, Monel).
Flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification.
