How to select an industrial valve
Review function, fluid, pressure, temperature, size, ends, material, permitted leakage and operation together.
Technical library
Concise guidance for better technical decisions
Core concepts, selection routes and common pitfalls before procuring piping equipment.
Pipe, tube and hose differences
Nominal size, outside diameter, sizing convention and application differ across these three families.
Flange and gasket selection
Class, material group, facing, design temperature and gasket chemical compatibility must be evaluated together.
Understanding pipe schedule
Schedule is not one fixed wall thickness; the actual wall varies with size and pipe standard.
Permanent or detachable joint
Maintenance access, permitted leakage, installation conditions and inspection requirements drive the connection type.
Preparing a technical enquiry
Clearly state description, size, schedule or class, material, standard, quantity, service and required documents.

A standard does not replace the project specification
A standard is a general reference; the accepted edition, supplementary requirements, inspection, documentation and project constraints must be checked separately.
