tubulares

Tubulares is a term used to describe anything that has the form of a tube or pipe, and is employed across several fields to denote a hollow, elongated structure with a central lumen. In English, tubular or tubulars can refer to objects, materials, or shapes that are cylindrical and hollow; in Romance languages such as Spanish and Portuguese, tubulares functions as the plural adjective or noun form for tubular objects.

In biology and medicine, tubules are small hollow passages in organs such as renal tubules in the kidney, seminiferous tubules in the testes, and the cochlear tubules in the inner ear. They are characterized by a tubular lumen lined by epithelium and play roles in transport, secretion, and absorption.

In botany, tubes occur in various structures, notably tubular flowers where petals form a long corolla sheath that often houses nectar and guides pollinators; tubular leaves or stems describe elongated, tube-like morphologies.

In construction and engineering, tubular structures include steel tubes used as columns or frames; tubular steel offers a high strength-to-weight ratio. Tubular design is also applied in lighting, ventilation ducts, and architectural forms that emphasize a stretched cylindrical silhouette.

In the oil and gas industry, tubulars refer to standard pipe products such as drill pipe, production tubing, casings, and line pipe used for drilling, completing, and operating wells.
