Thrust blocks Most properly bedded Bondstrand 2000MP installations do not require thrust blocks. Consult Ameron for recommendations for systems operating at elevated temperatures. Live loads Bondstrand 2000MP will carry H20 wheel loadings of at least 16,000 lb (7250 kg) when properly bedded in compacted sand in stable soils and provided with at least 3 ft (1 m) of cover.

Buried installations Recommended maximum support spacing for Bondstrand 2000MP pipe at various operating temperatures. Span recommendations are valid for normal horizontal piping support arrangements, a compromise between continuous spans and simple spans, but include no provision for weights such as fittings, flanges, etc. or thrust from branches, turns, etc. Span recommendations are calculated for a maximum long-term deflection of 1⁄2 inch to ensure good appearance and adequate drainage. Values are based on 1⁄2 inch deflection at midspan for fluid specific gravity = 1.0. For continuous spans, increase values by 20%. For end or single spans, decrease values by 20%.
