Construction materials — Is it accurate that a wide range of plastic pipe types, in both rigid and flexible forms, are used across building services and construction applications?

Introduction / Context:
Plastic piping materials have diversified construction options due to corrosion resistance, weight savings, and ease of installation. Understanding where plastics fit informs selection decisions on drawings and specifications for plumbing, HVAC, electrical, and specialty systems.

Given Data / Assumptions:

• Statement claims wide use of both rigid and flexible plastic pipes.
• Examples include PVC, CPVC, ABS, HDPE, PEX, PP-R, and conduit types.
• Applications span water supply, drainage, venting, hydronic systems, and cable protection.

Concept / Approach:
Rigid plastics (e.g., PVC, CPVC) provide dimensional stability and ease of joining with solvent cements or mechanical couplings. Flexible forms (e.g., PEX, certain HDPE coils) simplify routing and reduce fittings. Selection depends on temperature, pressure, chemical compatibility, and code compliance. Documentation must specify material standards, joining methods, and supports to ensure safe installation.

Step-by-Step Solution:
1) Classify plastics into rigid and flexible families.2) Map materials to applications and joining methods.3) Account for code and environmental constraints in specifications.4) Conclude that a wide variety of plastic pipes are indeed used in construction.

Verification / Alternative check:
Product standards and codes list numerous plastic pipe types and fittings approved for building services; supplier catalogs reinforce the breadth of options.

Why Other Options Are Wrong:

• Incorrect: Ignores the prevalence of plastics in modern construction.
• Low-pressure only / residential only / conduit only: Plastics are used in diverse pressure and non-pressure systems across sectors.

Common Pitfalls:
Mismatching plastic type to temperature/pressure; incorrect solvent cement; insufficient support spacing; overlooking UV sensitivity for exposed runs.

Final Answer:
Correct
