1. Introduction

This method statement outlines the procedures for the installation and testing of chilled water piping. It aims to ensure that the installation process adheres to safety standards, quality requirements, and industry best practices. The chilled water piping system will be installed by the approved engineering drawings and specifications.

2. Scope

This method statement covers the installation and testing of chilled water piping from the source to the respective endpoints, including but not limited to the following:

a. Chilled water supply and return piping.

b. Insulation of chilled water piping (if applicable).

c. Supports, hangers, and anchors for the piping.

d. Valves, fittings, and accessories.

3. Equipment and Materials

The following equipment and materials will be required for the installation:

a. Chilled water pipes, fittings, and accessories as per specifications.

b. Insulation materials (if applicable).

c. Welding machine or threading machine (depending on the piping material).

d. Cutting and grinding tools.

e. Welding electrodes or threaded rods.

f. Measuring tape, spirit level, and other necessary tools.

g. Safety equipment (helmets, gloves, goggles, etc.).

4. Installation Procedure

a. Pre-Installation Inspection:

• Ensure that the area is clear and ready for installation.
• Check the engineering drawings to confirm the piping route and location of hangers/supports.
• Verify that the piping materials conform to the required standards and specifications.

b. Installation of Piping:

• Lay out the chilled water piping as per the approved drawings and secure the route, avoiding any interference with other services.
• Cut and prepare the pipes to the required lengths, ensuring clean and burr-free edges.
• Join the pipes using either welding or threading methods, depending on the piping material. Ensure strong and leak-free connections.
• Install valves, fittings, and accessories according to the design requirements.
• Provide expansion loops/expansion joints where necessary to accommodate thermal expansion and contraction.
• Properly support the chilled water piping at regular intervals using hangers, supports, and anchors. The supports should be designed to handle the weight and movement of the piping system.
• If the piping is required to pass through walls or floors, use suitable sleeves or firestop materials to maintain fire safety integrity.

c. Insulation (if applicable):

• If insulation is required for the chilled water piping, ensure that it is applied as per the approved specifications.
• Insulate all chilled water pipes, fittings, and accessories to prevent condensation and maintain the temperature of the chilled water.

d. Flushing and Cleaning:

• Before testing, thoroughly flush the entire chilled water piping system to remove any debris, dirt, or foreign particles that could potentially cause damage to equipment or block the flow.

5. Testing Procedure

a. Hydrostatic Testing

• Fill the chilled water piping system with water, ensuring all air is expelled from the pipes.
• Gradually increase the pressure to 1.5 times the maximum working pressure or as specified in the design, and hold it for a duration as per project requirements (typically at least 2 hours).
• Check for any visible leaks or pressure drops. Any identified leaks must be rectified, and the test repeated until the system is leak-free.

6. Health, Safety, and Environment (HSE)

• All personnel involved in the installation must wear appropriate personal protective equipment (PPE) at all times.
• Ensure that all safety protocols and procedures are followed during installation and testing.
• Adequate fire extinguishers and first aid kits should be readily available at the installation site.

7. Quality Control

• Regular inspections should be carried out during the installation to ensure compliance with the specifications and engineering drawings.
• Any non-conformities or deviations should be documented, reported, and rectified before continuing the installation.

8. Record Keeping

• Maintain detailed records of the installation process, including photographs and relevant test results.
• Ensure that all necessary certificates, manufacturer's documentation, and approvals are obtained and filed appropriately.

9. Conclusion

This method statement outlines the procedures for the safe and efficient installation and testing of chilled water piping. Strict adherence to safety standards, quality control measures, and approved engineering drawings will be maintained throughout the process. Any deviations or non-conformities will be promptly addressed to ensure the successful completion of the project.
