On completion of the test, the water is to be released and drained completely
away as rapidly as possible, the system being then thoroughly sluiced through
to ensure the removal of as much dirt and dross as possible before being
refilled and put into service.
The test pressures to be supplied to the various services are as follows:

expansion and contraction is taken up without excessive stress on the pipe or
the building structure, and where this cannot be achieved with the normal run
of pipework, special expansion loops or expansion joints shall be provided.
Expansion loops shall be made up from pipe of the same quality as the main,
either with welded elbows or fabricated from a single length of pipe with
pulled or fire-set bends.
Expansion joints shall be of the stainless steel bellows type adequately
supported, in accordance with the manufacturer's instructions and with guides
on the mains adjacent to the joints.
Expansion joints shall be as manufactured by Engineering Appliances (1978)
Limited. Anchors shall be provided at intervals to ensure expansion is
absorbed at the determined places, and shall consist of a short length of pipe,
flanged at each end and positively fixed to the building structure by heavy
mild steel angle or channel iron.
`Cold draw' shall be applied, suitable to the pipework and service, by pulling
up through long bolts on the expansion loop/joint flanges. The long bolts shall
afterwards be replaced by normal or expansion unit bolts.
The provision for expansion shall be checked before and after any enclosure of
the pipework.
1.45
Protection of Pipework

glazed picture frame and fixed in the plantroom in an agreed position.
1.48
L.P.H.W. Pipework Insulation
All LTHW pipework shall be insulated, including mains and sub-circuits,

terminal units shall be un-insulated.
Pipework shall be insulated with rigid mineral fibre or CFC free phenolic
foam preformed sectional insulation, securely fixed and finished with foil
faced finish Class ‘O’ sheeting with overlaps neatly pasted down.
Bends and fittings shall be formed from mitred and trimmed sections cut to
ensure that a good contact with the surface to be insulated is made and that
the true shape of the fitting is maintained. Straight sections of insulation
shall be applied in lengths up to 1.2m in half segment sections, adjoining
sections being firmly butted together and joined with minimum 100mm
wide, self adhesive foil faced finish dead soft aluminium tape, applied over a
clean surface and firmly pressed down.
The insulation shall be continuous except where brackets or rollers, valves,
unions, flanges, etc are encountered.
Where rollers are encountered the insulation shall be stopped 25mm short
either side and finished with aluminium caps. Where brackets are
encountered, the insulation shall be carried through over the bracket.
End caps of sufficient size to extend from the outside of the insulation to
the outside of the pipework.

covered with 20 gauge hammerclad aluminium sheeting.
The cladding shall be continuous except where insulation terminates at
flanges, valves etc. Where this occurs the end shall be fitted with a polished
aluminium end cap fixed over the aluminium cladding. These end caps shall
be of sufficient size to extend from the outside of the cladding to the outside
of the pipework.
Bends, tees and other junctions shall be formed using purpose made pattern
cut sections.
Joints shall be hidden on the rear, or underside of low level pipework and
on the topside of high level pipework in order to present the cleanest
possible aspects of the work. Traverse joints shall be made using self
tapping stainless steel screws or aluminium pop rivets. All traverse joints
shall line up exactly with those joints on any parallel runs of pipework
wherever practicable.
All valves, strainers, flanges and unions on all services shall then be
enclosed with 20 gauge polished aluminium boxes formed to suit the shape
of the unit being insulated.
Mineral fibre mating shall be used in lieu of rigid sections. MWS & CWS
valves shall also be covered with denso paste.
Rubber compression strips shall be fitted to all edges of the cladding on
boxes, between the box ‘gland’ and the outer cladding of the adjoining work
in order to close gaps between the two.

fastened together on the opposite side by a quick release catch of the toggle
hook pattern. PK screws or any other form of fixing will not be permitted.
Seam joints in the construction of the box shall be lapped and riveted or
