"Calculation of containers and apparatuses of thermoplastics; standing round, unpressurized containers"

This document establishes a technical framework for the design and calculation of vertical, circular, atmospheric pressure vessels constructed from thermoplastic materials. It outlines specific methodologies to determine dimensional stability and structural integrity under operational conditions. The guidelines focus on material properties relevant to thermoplastics, addressing factors such as pressure resistance, temperature variations, and long-term performance. By providing detailed procedures for load analysis and stress evaluation, the standard ensures that manufactured equipment meets consistent safety and reliability criteria. It serves as a reference for engineers engaged in the development of process plants and storage systems where thermoplastic components are utilized. The text covers essential parameters for sizing and validating these vessels, facilitating uniform engineering practices across the industry. Adherence to these calculated approaches supports the prevention of failures and extends the service life of the equipment. The content is particularly relevant for applications involving chemical processing and fluid storage where corrosion resistance and lightweight construction are critical advantages of thermoplastic usage.
