Standard Specification for Seamless Copper Tube for Natural Gas and Liquified Petroleum (LP) Gas Fuel Distribution Systems
|Publication Date:||15 June 1995|
|ICS Code (Petroleum products and natural gas handling equipment):||75.200|
1.1 This specification establishes the requirements for Type GAS seamless Copper UNS No. C12200 tube suitable for use in above ground natural gas and liquified petroleum (LP) gas fuel distribution systems installed in conformance with the requirements of American National Standard (ANSI) Z223.1, National Fire Protection Association Standard (NFPA) 54, Canadian Gas Association Standards (CGA) B149.1 and B149.2 which are commonly assembled with flared fittings or brazed joints.
1.2 O60 (soft annealed) temper gas tube is produced in the range of standard sizes 0.375-0.875 in. outside diameter; H58 (drawn general purpose) temper gas tube is produced in the range of standard sizes 0.375-1.125 in. outside diameter.
1.3 O60 (soft annealed) temper gas tube systems are normally assembled with single SAE J512 or J513 45° flared fittings (2.3) although brazed connections using wrought (ASME/ANSI B16.22) or cast (ASME/ANSI B16.18) fittings (2.4) may be permitted by local or code requirements. H58 (drawn general purpose) temper gas tube systems must be assembled with brazed connections.
NOTE 1--Tube temper and applicable size are determined by installation code requirements.
1.4 Flared fittings (SAE J512 or J513--Section 2.3) used with seamless copper tube for natural gas and liquified petroleum (LP) gas fuel distribution systems shall be free of residual stresses.
1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
