According to online information, municipal class 2 is suitable for gas pipeline projects with pressures below medium pressure. However, GB1 does not specify a pressure range, with the default being up to 4.0 MPa. So can construction teams handle projects with high pressure (1.6 MPa)? Seeking advice
