What’s The Difference Between Toriconical Heads and Conical Heads

Toriconical Heads and Conical Heads

This guide explains the difference between toriconical heads and conical heads for pressure vessels and tank transitions. You’ll learn how the toroidal knuckle radius changes stress at the cone-to-shell junction, impacts fabrication and inspection, and affects ASME/PED documentation. Includes a practical RFQ checklist and a comparison table to help buyers specify the right head geometry and avoid fit-up surprises.

How We Build a Cylindrical Tank with Hemispherical Heads

Hemispherical Heads

A cylindrical tank with hemispherical heads looks simple, but the build has a lot of “gotchas.” This post walks through the real-world process: material selection, forming, fit-up, welding, inspection/NDT, and the documentation that code buyers expect. You’ll learn what to specify early to avoid rework, delays, and rejected parts.
