    However, if the pipe is considered unconstrained, the external pressure of the vacuum exceeds the critical collapse pressure. In the case of unconstrained pipe, DR 13 would be the suitable choice. My question is, is it safe to assume through diligent supervision of the construction, and tight specifiions for the eedment,and primary / secondary fill, that the DR 21 will be sufficient?
