What “ASME-Coded” Means for a Chromatography Column

What ASME-coded means

ASME-coded means a vessel is designed, fabricated, inspected, and stamped in accordance with the ASME Boiler and Pressure Vessel Code (BPVC) — the standard published by the American Society of Mechanical Engineers that governs how pressure-containing equipment is built. A column that carries the code stamp has been made by a certified shop, to qualified weld procedures, and verified by an authorized inspector.

In short: it’s third-party-backed assurance that the vessel was engineered to hold its rated pressure safely, with the documentation to prove it.

Why it matters for a chromatography column

A packed process column is a pressure vessel — it holds media and fluid under pressure during packing and operation. In a GMP facility, using ASME-coded vessels:

• Reduces risk — the design and welds are qualified for the rated pressure, with margin.
• Eases validation and audits — coded vessels come with documentation inspectors and quality teams expect to see.
• Satisfies site and insurer requirements — many facilities require coded pressure equipment as a matter of policy.

How it relates to IQ/OQ and material certs

ASME coding covers the vessel’s pressure integrity. It sits alongside the other documentation a regulated buyer needs: material test reports (e.g., for 316L stainless or C-22 Hastelloy), surface finish records, and IQ/OQ documentation that supports installation and operational qualification. Together they form the paper trail that lets a column be validated and brought online.

What to ask a fabricator

• Is the column built and stamped to the ASME BPVC?
• What is the rated design pressure, and what is the margin?
• Will you provide material test reports and IQ/OQ documentation packages?
• What surface finish and CIP/SIP design are included?

Mann Welding is an ASME-certified fabricator. Every column and hydraulic control unit is built in the USA to the code, with IQ/OQ documentation available. For the material side of the decision, see choosing a column material.
