Quy cách kích thước mặt bích thép Steel Flange
Tiêu chuẩn mặt bích thép
Quy cách kích thước mặt bích thép các theo tiêu chuẩn thông dụng: tiêu chuẩn Anh BS 4504, tiêu chuẩn Nhật Bản JIS B2220, Mỹ ANSI B16.5.
Mặt bích dùng để kết nối các ống thép với nhau, mỗi đầu ống thép hàn với mặt bích, sau đó kết nối các đầu ống có mặt bích với nhau bằng bu lông.
Bảng kích thước mặt bích thép BS 4504 / JIS B2220/ ANSI B16.5
