What do tables for varying wall thickness of pipe typically provide?

Tables for varying wall thickness of pipe are designed to provide specific information about the physical characteristics of the pipe, which includes mass per unit length, such as kilograms per meter. This information is crucial for engineers and designers when selecting materials for a project, as it helps them understand the weight implications, structural integrity, and overall material requirements.

While the other options might be relevant in various contexts, they do not directly pertain to the primary purpose of these tables. Cost per meter may be determined from different resources or pricing sheets, length of pipe sections can vary based on project needs and do not hinge on wall thickness, and warranty information typically comes from manufacturers or suppliers rather than being a fundamental characteristic of the pipe itself. Therefore, the correct answer focuses on the essential data that these tables are designed to present.
