                燃气输配的压力机制分级是怎么分级的?

                作者:       来源:       发布日期:2018-01-06

                    国家《城镇燃气╱设计规范》(GB50028-2006)规定,我国燃气输配的压力机制分为七级:

                等级 压力范围
                低?压 P<0.01MPa
                中压B 0.01MPa≤P≤0.2MPa
                中压A 0.2MPa<P≤0.4MPa
                次高压B 0.4MPa<P≤0.8 MPa
                次高压A 0.8MPa<P≤1.6MPa
                高压B: 1.6MPa<P≤2.5MPa
                高压A 2.5MPa<P≤4.0MPa
