CGA E-3 (R2014)

This standard specifies the connections on removable pipeline regulators and station outlets used in the welding, cutting and allied processes where the pipeline pressure does not exceed 200 psig (1380 kPa). Removable connections are those that are commonly and readily engaged or disengaged in routine use and service. A regulator connected to or in the pipeline by pipe threads, bolted flanges, etc., is not considered removable.
