All personnel engaged on welding operations must possess a current certificate of competence issued by an approved authority. These certificates must be produced for inspection by the Engineer before any welding is undertaken and renewal certificates must be provided every six months.

Each weld shall be given a suitable mark in order that the operative concerned may be identified. This will be rigidly enforced.

The Engineer reserves the right to order at random the cutting out of 2% of the welded joints for inspection and testing. Should any one of the above welds prove faulty in materials or workmanship, further removal of welds may be ordered up to a total of 4% of the welded joints. If the number of welds failing the tests within the above 4% is sufficient to suggest that an operative is not consistent in his standard, the Engineer may order any number of that operative's welds to be removed. The cutting out and repair of all such welds for inspection shall be at the cost of the Sub-Contractor.

Oxy-acetylene and metal arc welding of steel pipework shall be Class 2 to B.S. 2640, B.S. 2971 or B.S. 4515.

Fusion welded joints in copper shall be to B.S. 1077 and bronze welding by gas shall comply in every respect with B.S. 1724.

Gas welding of steel pipework of 65mm and above shall not be permitted unless prior permission is obtained.

Welding shall not be permitted on galvanized pipework under any circumstances.

No locally made ductile iron pipework, flanges or fittings will be accepted.

Generally, all ferrous piping systems shall comply with B.S. 806.

All screwed joints shall be made in compliance with B.S. 21 using jointing compounds carefully selected to suit the type of service.

An isolating valve/cock shall be provided for each pressure gauge.

Pressure gauges shall be installed where shown on the Drawings; and whether shown on the Sub-Contract Drawings or not, in the flows and returns connection of all pumps and chillers.

INSTALLATION

11.14 GENERAL

The Sub-Contractor shall provide all labour and material to form complete pipework systems and shall leave the installation adjusted to the designed flow rates.

All pipe runs shall be installed generally in accordance with the Sub-Contract Drawings but full allowance shall be made by the Sub-Contractor for the detailed development and co-ordination of the scheme and for the future removal and dismantling of sections of the Sub-Contract Works.

All pipework shall be free from burrs, rust and scale and shall be thoroughly cleaned before installation.

During the course of the installation, all open ends shall be plugged or capped to prevent ingress of dirt and on completion each system shall be thoroughly flushed out with clean water. Wooden bungs shall not be used for plugging pipework.

Where two or more pipe runs follow the same route, care shall be taken to ensure that all are parallel to each other and to the building structure, except for the required allowance for venting, etc. Pipework which is to be subsequently insulated shall be so spaced to allow an individual finish to each.

Air relief valve shall be provided at all high points where venting may be required, whether shown on

11.15 FALLS

Pipework shall be installed with correct falls to ensure adequate venting and draining.

11.16 JOINTS

Pipework installed for all particular type of joints are specifically called for in this section.

11.17 ANCHORS

No pipe joints shall be permitted within the thickness of walls or floors, etc.

Joints shall not be closer than 1.0m except where necessitated by fittings.

Anchors shall be positioned in association with pipework change in direction and propriety expansion compensators, etc., such as to absorb the stresses due to pipework expansion and internal pressures by transmission of such forces to the ground or structure at appropriate points.

The Sub-Contractor should particularly note that in addition to serving the purpose of constraining the pipeline, the anchors may be used in connection with testing of pipework, and at such times, it will be necessary to have the extreme ends of the main being tested held with the anchors to prevent the pipeline drawing apart due to the thrust pressures exerted at the end of the pipe.

Adequate pipe anchors shall be provided whether or not shown on the Drawings and shall be constructed from structural steel channel sections secured to the building structure.

11.18 GUIDES

Guides shall be of mild steel riders welded to the pipes on roller or PTFE sliding supports restrained with U-bolts on brackets or as otherwise detailed on the Drawings.

During sectional testing, the Sub-Contractor shall ensure that the expansion joints are adequately tied, anchored or removed to avoid damage to the bellows.

Wherever necessary, due allowance shall be made for the expansion and contraction of pipework by change in direction of pipework, or expansion loops, whether shown on the Sub-Contract Drawings or not.

At building expansion joints, and wherever else necessary, additional allowance shall be made by the provision of stainless steel axial or articulated bellows type expansion compensators complete with all necessary guides, etc., as recommended by the manufacturer to give a working life of not less than twenty years.

Each compensator shall maintain at least the same cross-sectional area as ajoining pipework for its entire length.

On larger diameter steel, ductile and grey iron pipes (150mm diameter and above) judicious use of "dresser" couplings or other equal flexible couplings shall be made in connection to all plant items.

Flexible couplings shall be fitted to pump suction and delivery connections and where indicated on the Sub-Contract Drawings or schematics.

Flexible couplings shall be line size, made from a multi-ply nylon fabric carcass with wire reinforced collars and stainless steel liners designed to suit the fluid conveyed and the working, test, and shock pressures that will be experienced in the various systems.

Manufacturers shall be alerted by the Sub-Contractor to the possibility of variations of service (e.g. on/off pump operation shock pressures, etc.) to ensure correct selection of items for the particular application.

11.20 PIPE SLEEVES

Where pipe pass through walls, floors, etc., the Sub-Contractor shall supply and install pipe sleeves.

Where pipes pass through walls, floors or ceilings rendered liquid-tight puddle flanges shall be supplied by the Sub-contractor and fixed by the Main Contractor.

Sleeves for cast iron, copper, steel, uPVC pipes shall be galvanised steel.

Where sleeves are fitted through floors, they shall extend to at least 50mm clear of finished floor.

Sleeves shall be of sufficient size to allow free movement of pipes and where pipes are insulated, the sleeves are to be oversized to allow the insulation to be carried through the sleeves.

Details of pipes through walls and floors to be submitted for checking before installation.

The Sub-Contractor shall set all sleeves in the shuttering of walls, floors, etc., before concrete is poured and in compliance with the Main Contractor programme. Where holes have to be cut through structure after concrete has been poured as a result of the Sub-Contractor's failure to provide the same, then all costs for this shall be to the Sub-Contractor's account.

Where exposed pipes pass through walls, ceilings and floors, hinged mild steel escutcheon rings are to be used. All plates are to be chromium plated steel and samples of such plates are to be submitted to the Engineer for checking.

Pipe sleeves shall also be provided where piping penetrates external walls and roofs. The space between pipe sleeves and the pipe or insulation shall then be completely caulked by the Contractor, with a soft, non-setting waterproof mastic compound giving an air and watertight seal.

Penetrations through roofs shall also be provided with a weatherproof apron and up stand curb or other provisions as may be specified elsewhere or shown on the Sub-Contract Drawings.

Where pipes pass through fire walls and floor slabs, a metal fire stop is to be welded or bolted around the pipe. This shall be in the form of a 6mm thick flange located in the centre of the slab/wall thickness and welded/screwed to the pipe, the flange being of the same diameter as the internal bore of the pipe sleeve.
