Description

CGA E-3 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 psi (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. Therefore, this standard does not apply to the following:

  • regulators built into equipment so as to become an integral part of a larger device;
  • high capacity regulators generally used in fixed locations and provided with inlet fittings larger than covered in this standard; and
  • regulators attached to the pipeline by pipe threads, flanges, etc.

All new pipeline installations shall incorporate the connections specified in Section 5.

This standard does not prejudice the continued use of acetylene and LPG type connections in service or in inventory at a manufacturer’s or user’s site that were manufactured before the effective date of this standard provided the connections are identifiable with the appropriate CGA markings.

The effective date of this standard is three years from the date of the publication of this edition, which was February 17, 2021. New acetylene and LPG pipeline installations on and after the effective date of this standard shall be in compliance with this standard.
