How to Specify Chemical Process Filtration: A Practical Guide for Engineers

Chemical process filtration is about more than selecting a filter with the correct connection size. The equipment must withstand the process medium, operate within the required pressure and temperature limits, retain the correct particulate sizes and meet the safety and documentation requirements of the installation. This guide walks through material compatibility, elastomer selection, ATEX and SIL requirements, operating envelopes, particulate characteristics, sealing strategies and documentation — so the specification is right from the start.

High-Viscosity Filtration Explained: Pressure Drop, Media Choice and Sizing

Filtering a thick fluid is not the same as filtering water. The pressure drop across a filter element rises in proportion to the fluid's viscosity, so a filter that behaves perfectly on a thin fluid can starve a pump on a viscous one. This guide explains why viscosity changes the rules, then covers strainers and filters, surface and depth media, magnetic separation, temperature and shear, sizing, and the problems that most often show up in service.

High Pressure Cone and Thread Fittings: A Selection and Assembly Guide

High pressure cone and thread fittings join tube to valves, fittings and manifold blocks with a metal-to-metal seal rather than an elastomer. This guide explains how the connection works, how the HIFLUX range is split by pressure class from 10,000 to 150,000 psi, and what to check when specifying, preparing and assembling a joint.

High Pressure Regulators: Choosing Between GPR, HPR, BPR and ABPR

High pressure regulators fall into two families: pressure-reducing regulators that hold the outlet steady, and back pressure regulators that hold the inlet steady. This guide compares the HIFLUX GPR, HPR, BPR and air operated BPR so you can match the regulator to the job before you request a quote.

High-Pressure Check Valves: Preventing Reverse Flow in Critical Systems

In high-pressure gas and liquid systems, controlling the direction of flow is essential. A high-pressure check valve allows media to move in one direction while restricting flow in the opposite direction. HIFLUX offers O-ring and ball-type designs across multiple tube sizes, with pressure ratings reaching 100,000 psi.
