Pipework Sample Clauses

The Pipework clause defines the requirements and standards for the installation, maintenance, and quality of piping systems within a project. It typically outlines the types of materials to be used, installation methods, testing procedures, and compliance with relevant codes or regulations. For example, it may specify that all pipe joints must be leak-tested before commissioning or that only certain grades of metal piping are acceptable. The core function of this clause is to ensure that all pipework is safe, reliable, and fit for purpose, thereby minimizing the risk of leaks, failures, or non-compliance with legal standards.
Pipework. TS-777 Excavation of any section of the work shall not start until a complete set of the pipes and components for that section is available. TS-778 The trench shall be as narrow as practicable but not less than the pipe diameter plus 300 mm from each side to permit adequate compaction of side fill. Adequate working space shall be left for pipe jointers and joint holes shall be formed where necessary.

Mixing of codes from different countries of origin is not acceptable. 2. All pipes are to be sized to ensure that the process requirement is met with an economically viable and energy efficient solution. Pipe supports shall be provide if the pipe is not buried. 3. The pipeline shall conform to environmental regulation. Pipes are to follow best practices and shall adopt the same Pipework Standard/Code currently at the facility. 4. The design should incorporate the provision for meaningful in-service non-destructive testing during periodic overhauls of the pipeline. The provision and installation of the primary measuring elements for the control and instrumentation will all be required. The provision of all isolating valves and the necessary actuators will be required. 5. All pipes are required to be mild steel, the Contractor determines the required pressure rating of the pipe based on the equipment and pumping system selected. 6. All pipes are required to be compatible for use with the temperature unit. 7.

Pipework. All pipework, connections and delivery systems must conform to British Standard 6572. Pipes laid underground must be buried to a minimum depth of 750mm. Pipe laying may be done by trenching, mole plough or sub-soiler, depending on soil type and machinery available. The ground must be reinstated to original levels with the top soil returned to the surface. Where open ditches are crossed, the pipe must be covered by a tubular steel guard or sleeve pipe and laid 600 mm below the ditch bottom to allow for ditch cleaning. Where farm tracks are crossed, the water pipe must lay on a 75mm bed of sand and be covered by sand to a depth of 100mm before being overlain by backfill. The water supply must be controlled by isolating valves/stop cocks at the point of supply and at each trough. The isolating valves/stop cocks must be protected against frost, they must be easily accessible and protected from damage by livestock. Where they are buried, this must be at a minimum of 600mm and must be easily accessible through a covered inspection chamber. Underground pipework must not damage sites of archaeological or historic interest. Any spoil must not be used to fill and level adjacent wet areas or be put on any sites of archaeological or ecological importance. The water supply must be maintained in good condition for the duration of the agreement. The water trough should be placed in a free draining area to minimise damage by poaching. It should not be placed on or near sensitive habitats or species and the area should ideally be a sacrifice area. The trough should not be located near watercourses, on areas vulnerable to soil erosion or on or near a site of archaeological or historic interest. Troughs made of galvanised steel must comply with British Standard 3445. Other materials such as concrete or moulded polyethylene may be acceptable if agreed with your Natural England contact and if it complies with the appropriate British Standard. The water trough must be installed on a level base so it does not spill water. The trough must either be connected to a water supply or it must be supplied from a ▇▇▇▇▇▇ on a regular basis. The water trough must be maintained in good condition for the duration of the agreement.

Pipework. All suction and delivery pipes shall be connected to the pump casing by means of flexible connections. All flexible connections shall be installed as close to the pump’s casings as possible, and in any event, shall be between the suction valve and the pump casing and delivery non-return valve and the pump casing. In all cases the flexible connection shall be in the section of piping of smallest diameter. Double Victaulic joint are generally preferred for flexible connections, but approved re-enforced rubber bellow units are acceptable for low-pressure services. All valves and pipework external to the pump casing and separated there from by means of flexible connections shall be securely anchored to prevent movement.
