给排水隐蔽预埋详细工艺流程

English Answer:

Concealed Embedded Piping and Drainage: Detailed Process Flow.

Pre-Installation Preparation:

1. Verify the construction drawings and obtain approval from the relevant authorities.

2. Establish reference points and survey the site to determine the precise locations of fixtures and piping.

3. Clear the work area of any obstructions or debris.

Material Selection and Inspection:

1. Select piping materials that comply with the

building code and project specifications. Common materials

include PVC, CPVC, PEX, and copper.

2. Inspect all materials upon delivery to ensure they are free from defects or damage.

Pipe Fabrication and Assembly:

1. Cut and join pipes to the required lengths and configurations using appropriate tools and techniques.

2. Deburr and clean all pipe ends before assembling them.

3. Use fittings to connect pipes at angles, changes in direction, or to branch off into multiple lines.

4. Secure pipe connections using glue, solder, or mechanical fasteners as per the manufacturer's instructions.

Installation:

1. Rough-in the piping system by placing it in the

designated locations within the walls, ceilings, or floors.

2. Secure the pipes to structural supports using straps, hangers, or clamps.

3. Ensure that pipes have proper slope and drainage to prevent water stagnation.

4. Connect fixtures to the piping system using flexible connectors or compression couplings.

Testing and Inspection:

1. Conduct a pressure test to check for leaks or weak connections.

2. Inspect all joints and fixtures for proper operation and adherence to building codes.

3. Obtain approval from the relevant authorities before closing up walls or concealing the piping.

Additional Considerations:

1. Install access panels or cleanouts at strategic locations for future maintenance and repair.

2. Label pipes and fixtures clearly for easy identification.

3. Protect the piping system from freezing temperatures or other environmental hazards.
