head covers and the insulation shall conform a,s close as possible to the

! contour of the heater head. Head c~fers shall be separate from shell covers and readily removable for maintenance of heaters without destruction

. of the insulation.

' 8.' 15 The completed installation of weatherproof outer covering as specified above shall be guaranteed to provide adequate protection for the insulation and to hep it dry under all normal climatic conditions existing in the locality of

'this installation.

This guarantee extends over a period of one year from the date of commercial plant operation and includes performance of all work which may be required for.necessary insulation and finishing.

8.16 All joints of outer covering for horizontallines shall be located on the

. side of the pipe with laps turned downward.

8.17 Piping All pipe up to and including 12 inch nominal diameter a.

shall be covered with sectional insulating material made up in 36 inch sections having not more than twci longitudinal joints. Insulating material for piping

(,

over 12 inch nominal size and*on all bends, may be made of segmental blocks, molded to fit circumference f,.

of pipe.

Where parallel pipes are on such close centers that separate covering of each pipe is impractical, the pipe may be covered as a group.

Where sectional or block covering is applied in two c.

/O b.

The sectional or block insulation shan be secured with No.16 B&S gauge Monel or stainless steel wire, and shall overlap the adjacent piping insulation to a minimum of 2 inches. Filler rings of the same material shan be provided, if necessary, to insure a good bearing on the piping insulation and on the periphery of the flanges. Covers shall be finished to a smooth cylindrical form, and for each size of pipe shan be uniform in width and diameter. Covers shan be of a design which will permit the nanges and bolts to heat up quickly and be maintained at a temperature as nearly as possible equal to that of the pipe, thus avoiding excessive strains. 'The Sub-contractor shall furnish for the approval of the Contractor, a sketch showing the proposed con-struction of these covers.

('.

Flanges shan in no case be permanently covered until c.

'-~

l the piping in which they are located has been tested and made tight. Flanges covered with Class HI, or IV insulation shall be furnished with temporary covers for testing in order to avoid excessive temperature difference in the Hanges and flange bolts. The test for tightness will normany consist of subjecting the piping to approximate operating conditions for 24

hours, d.

The temporary Hange covers shall be applied and removed by the Subcontractor.

At au flanged joints on piping and equipment the in-e.

sulation shall be tapered-off at an angle of approx-imately 45 degrees on both sides of the joint for a length sufficient to permit removing Hange bolts or studs without damage to the r overing.
