Sec. 192.177  Additional provisions for bottle-type holders.

    (a) Each bottle-type holder must be--
    (1) Located on a site entirely surrounded by fencing that prevents 
access by unauthorized persons and with minimum clearance from the fence 
as follows:

------------------------------------------------------------------------
                                                             Minimum
          Maximum allowable operating pressure            clearance feet
                                                             (meters)
------------------------------------------------------------------------
Less than 1,000 p.s.i. (7 MPa) gage....................         25 (7.6)
1,000 p.s.i. (7 MPa) gage or more......................         100 (31)
------------------------------------------------------------------------

    (2) Designed using the design factors set forth in Sec. 192.111; 
and
    (3) Buried with a minimum cover in accordance with Sec. 192.327.
    (b) Each bottle-type holder manufactured from steel that is not 
weldable under field conditions must comply with the following:
    (1) A bottle-type holder made from alloy steel must meet the 
chemical and tensile requirements for the various grades of steel in 
ASTM A 372/A 372M.
    (2) The actual yield-tensile ratio of the steel may not exceed 0.85.
    (3) Welding may not be performed on the holder after it has been 
heat treated or stress relieved, except that copper wires may be 
attached to the small diameter portion of the bottle end closure for 
cathodic protection if a localized thermit welding process is used.
    (4) The holder must be given a mill hydrostatic test at a pressure 
that produces a hoop stress at least equal to 85 percent of the SMYS.
    (5) The holder, connection pipe, and components must be leak tested 
after installation as required by subpart J of this part.
